Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomena, and research findings.

Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. These skills are especially helpful at school and in the workplace, where employers prioritize the ability to think critically. Find out why and see how you can demonstrate that you have this ability.

Examples of Critical Thinking

The circumstances that demand critical thinking vary from industry to industry. Some examples include:

• A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
• A plumber evaluates the materials that would best suit a particular job.
• An attorney reviews the evidence and devises a strategy to win a case or to decide whether to settle out of court.
• A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.

Why Do Employers Value Critical Thinking Skills?

Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.

Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.

Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter and during your interview.

How to Demonstrate Critical Thinking in a Job Search

If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.

Add Keywords to Your Resume

You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your work history, include top critical thinking skills that accurately describe you. You can also include them in your resume summary, if you have one.

For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”

Mention Skills in Your Cover Letter

Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.

Show the Interviewer Your Skills

You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.

Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.

Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.

Top Critical Thinking Skills

Keep these in-demand skills in mind as you refine your critical thinking practice —whether for work or school.

Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with analytical skills can examine information, understand what it means, and properly explain to others the implications of that information.

• Asking Thoughtful Questions
• Data Analysis
• Interpretation
• Questioning Evidence
• Recognizing Patterns

Communication

Often, you will need to share your conclusions with your employers or with a group of classmates or colleagues. You need to be able to communicate with others to share your ideas effectively. You might also need to engage in critical thinking in a group. In this case, you will need to work with others and communicate effectively to figure out solutions to complex problems.

• Active Listening
• Collaboration
• Explanation
• Interpersonal
• Presentation
• Verbal Communication
• Written Communication

Critical thinking often involves creativity and innovation. You might need to spot patterns in the information you are looking at or come up with a solution that no one else has thought of before. All of this involves a creative eye that can take a different approach from all other approaches.

• Flexibility
• Conceptualization
• Imagination
• Drawing Connections
• Synthesizing

Open-Mindedness

To think critically, you need to be able to put aside any assumptions or judgments and merely analyze the information you receive. You need to be objective, evaluating ideas without bias.

• Objectivity
• Observation

Problem-Solving

Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan. Employers don’t simply want employees who can think about information critically. They also need to be able to come up with practical solutions.

• Attention to Detail
• Clarification
• Decision Making
• Groundedness
• Identifying Patterns

More Critical Thinking Skills

• Inductive Reasoning
• Deductive Reasoning
• Noticing Outliers
• Adaptability

• Project Management
• Ongoing Improvement
• Causal Relationships
• Case Analysis
• Diagnostics
• SWOT Analysis
• Business Intelligence

Key Takeaways

• Demonstrate you have critical thinking skills by adding relevant keywords to your resume.
• Mention pertinent critical thinking skills in your cover letter, too, and include an example of a time when you demonstrated them at work.
• Finally, highlight critical thinking skills during your interview. For instance, you might discuss a time when you were faced with a challenge at work and explain how you applied critical thinking skills to solve it.

Science students often experience difficulties as a result of their inability to see that multiple interpretations of the same data can coexist. Perry’s scheme helps show that such students are not lazy, but rather that their perceptions are limited by their stage of development. Understanding the different stages may help science teachers consider the best ways of presenting material in order to help students make the transition from one stage to the next.

Arons, Arnold B. “‘Critical Thinking’ and the Baccalaureate Curriculum.” Liberal Education 71.2 (1985): 141-157.

First asks, “What is involved in critical thinking?” Answers: Asking “how do we know? What is the evidence?” Being aware of gaps in knowledge. Distinguishing between fact and conjecture. Distinguishing between an idea and the name of that idea, and providing definitions. Looking for (hidden) assumptions. Performing hypothetico-deductive reasoning. Knowing inductive and deductive reasoning. Intellectual self-reliance. Being aware of own thinking process. Then discusses why one should bother with critical thinking, bemoans the lack of it in American students, and discusses how to increase or decrease it in students.

Baker, Paul J. “Learning Sociology and Assessing Critical Thinking” Teaching Sociology . 8.3 (April 1981): 325-63.

Reviews works of philosophers, educators, and sociologists who have examined critical thinking as central to the learning process. Suggests 3 strategies to improve the sociology teacher’s capacity to assess critical thinking: a survey of existing instructors, development of analytic tools to assess existing test items, and teacher-developed evaluation materials.

Bean, John. “Helping Students Read Difficult Texts.” Engaging Ideas: The Professor’s Guide to Integrating Writing, Critical Thinking, and Active Learning in the Classroom . San Francisco: Jossey-Bass, 1996. 133-147.

Instructors often note that poor reading and poor writing are interlinked. Reading difficulties may stem from a variety of causes–ten are listed here–and understanding the causes can help instructors devise strategies to help students read more effectively. A variety of suggestions for discussing more effective strategies are given, along with some guidelines in how to construct assignments that require students to employ better reading strategies.

Berthoff, Ann. “Speculative Instruments: Language in the Core Curriculum.” The Making of Meaning: Metaphors, Models, and Maxims for Writing Teachers . Montclair, NJ: Boynton/Cook, 1981. 113-126.

Claims that teaching writing is teaching critical thinking. 3 points about this relationship: observation is central to all disciplines, and learning to observe is learning to think critically; learning terms of art is learning concepts of a field; all disciplines use rhetorical ideas of invention and disposition (organization). Discusses 4 uses of language in all disciplines: speaking, hearing, reading, and writing. Can use writing to relate other aspects of language use in a course together (e.g. to relate lectures to texts).

Brand, Manny. “Toward a Better Understanding of Undergraduate Music Education Majors: Perry’s Perspective.” Bulletin of the Council for Research in Music Education 98 (1988): 22-31.

Music teacher educators often become dismayed when their students fail to demonstrate the type of intellectual engagement with the topic that the educators expect. The Perry model of intellectual development, however, helps to explain the different stages that students move through as they become incorporated into the academic community, and examples of these stages are sketched out. Music teacher educators may want to consider that their students’ responses will, in some ways, be restricted by their students’ stage of development. Therefore, music teacher educators may want to plan their courses in such a way as to foster transitions between the stages.

Brouwer, Peter. “Hold on a Minute Here: What Happened to Critical Thinking in the Information Age?” Journal of Educational Technology Systems 25 (1996-97): 189-197.

Although information technology (IT) is often touted as a means of improving the quality of teaching and learning, as well as enabling universities to offer more and better distance learning courses, IT also offers the potential for information overload. Educators need to teach information literacy so that students are better able to negotiate the amount and the quality of the information they receive. This type of literacy will enable students to make the distinction between information and knowledge.

Bruffee, Kenneth. “Constructive Reading.” A Short Course in Writing , 4th ed. New York: HarperCollins, 1993. 147-187.

In order to write well, students need to learn to read well. By reading constructively, students learn to recognize how meaning is created in a text. This selection offers a series of suggestions for getting students to read constructively, including using a descriptive outline–an outline that makes the distinction between a paragraph’s content and its rhetorical purpose.

Bruffee, Kenneth A. “Writing and Reading as Collaborative or Social Acts.” Sourcebook for Basic Writing Teachers . Ed. Theresa Enos. New York: Random House. 565-574.

Collaborative learning, as evidenced by the social nature of language use, is vital to the writing process. Insofar as writing is a type of “talking” to a reader in a coherent fashion, writing uses language that emerges from a community’s experiences as a means to communicate to that particular community. Entrance to the community is partially dependent upon being able to demonstrate competence within the specific discourse, which in turn implies that the writer has internalized the language conventions of that community in order to think about the topic–a type of thinking that involves what Vygotsky would call internalized social speech. That the writer often works alone fails to detract from the social nature of the act because the writer still internalizes the collaborative exchange within her imagination as part of the writing process.

Carpenter, C. Blaine, and James C. Doig. “Assessing Critical Thinking Across the Curriculum.” Assessing Students’ Learning. New Directions for Teaching and Learning no. 34. Ed. J.H. McMillan. San Francisco: Jossey-Bass, 1988.

Defines critical thinking. Discusses several standardized tests to assess critical thinking. Then outlines efforts to define, assess, and teach/strengthen critical thinking at several colleges and universities.

Carr, Kathryn S. “How Can We Teach Critical Thinking?” Childhood Education 65 (1988): 69-73.

Although most people recognize the need for critical thinking skills, the teaching of those skills is often divorced from content. As a result, critical thinking programs are often unsuccessful. A better program would integrate the application of critical thinking skills into the learning of content. Carr offers a review of various types of thinking skills activities–based upon Bloom’s Taxonomy of Cognitive Domain–applied to content areas.

Ellis, Edwin S. “Integrating Writing Strategy Instruction with Content-Area Instruction: Part II–Writing Processes.” Intervention in School and Clinic 29.4 (1994): 219-228.

Integrated Strategies Instruction Model (ISI) integrates learning strategy instruction with content-area instruction. One part of this model uses writing as a means to get students to think about and apply their content area knowledge. Special attention is given to understanding the writing problems of ineffective writers at the secondary level, especially students with mild learning handicaps. Students are introduced to an executive strategy which uses recursive thinking in order to solve problems, and then taught how to integrate the strategy into a written format. Studies indicate that this method of instruction is successful at improving student performance.

Gleichsner, Jean A. “Using Journal Articles to Integrate Critical Thinking with Computer and Writing Skills” NACTA Journal 38.4 (December 1994): 34-35.

Gleichsner presents an assignment of writing a critical review of a refereed journal article as a way to develop critical thinking in the classroom. She describes in detail the procedure the students follow in doing the assignment and then considers the assignment’s importance for undergraduates, especially in the sciences.

King, Patricia M., Phillip K. Wood, and Robert A. Mines. “Problem Structure, Tests of Critical Thinking and Disciplinary Differences: A Study of Critical Thinking Among College and Graduate Students.” Manuscript. Marked “Submitted for Publication. Do not quote without permission.” Version published in RHE 13.2 (Winter 1990): 167-186.

The authors use multiple measures of critical thinking to find out whether critical thinking ability varies by grad/undergrad, gender, discipline, and “academic ability.” Results: graduate students scored higher than undergrads, some differences that could be accounted for by academic ability and discipline. Results for the different tests differed.

Kiniry, Malcolm and Ellen Strenski. “Sequencing Expository Writing: A Recursive Approach.” College Composition and Communication 36.2 (May 1985): 191-202.

Kiniry and Strenski draw on their experience in UCLA’s writing program to describe a new approach to sequencing assignments in composition courses. They describe 8 typical tasks that undergraduate writers do in all their courses, in a developmental sequence requiring more complex skills: listing, definition, seriation, classification, summary, comparison/contrast, analysis, and academic argument. Each successive skill requires repeating and reinforcing the earlier skills. In addition, they provide sample assignments which would require varying levels of each skill.

Kitchener, Karen S., and Patricia M. King. “The Reflective Judgment Model: Transforming Assumptions about Knowing.” Fostering Critical Reflection in Adulthood: A Guide to Transformative and Emancipatory Learning . Ed. Jack Mezirow. San Francisco: Jossey-Bass, 1990. 159- 176.

Describes a model of the development of the ability to make reflective judgments (basically epistemology): the 7 stages people go through in their ability to make such judgments, and what influences this development. Discusses research indicating that this is a legitimate stage theory and research on education in the different stages.

Kitchener, Karen Strohm. “Educational Goals and Reflective Thinking.” The Educational Forum (Fall 1983): 75-92.

After summarizing history of work on reflective thinking, discusses research on, and models of, reflective thinking and its development. Describes a 7-stage model of the development of reflective thinking ability. Discusses educational implications: reflective judgment isn’t taught explicitly, or if it is epistemology is being ignored. Education might be able to help students progress through developmental stages.

Kitchener, Karen Strohm, and Patricia M. King. “The Reflective Judgment Model: Ten Years of Research.” Beyond Formal Operations III: Models and Methods in the Study of Adolescent and Adult Thought . Eds. M.L. Commons, C. Armon, L. Kohnberg, F.A. Richards, T.A. Grotzer and J. Sinnott. NY: Praeger. 2-29.

Describes a 7-stage model of the development of reflective judgment. Relates reflective judgment to Piaget’s formal operations. Describes how it is determined what stage a person is in, and summarizes research on the model, specifically research relating age and educational level to stage.

Kloss, Robert J. “A Nudge is Best: Helping Students through the Perry Scheme of Intellectual Development.” Journal of College Teaching 42.4 (1994): 151-158.

The Perry scheme of intellectual development is one of the few schemes with practical classroom applications. Drawing upon his ten-year experience of incorporating the scheme in his pedagogy, Kloss describes the different stages and offers concrete suggestions on how to challenge students to move from their initial dualist stage to commitment in relativism.

Law, Joe. “Critical Thinking and Computer-aided Instruction in Sociology 200.” Writing Across the Curriculum . 8 (March, 1998): 1, 3.

Instructors of large classes often have difficulty in knowing whether the students have read and understood the text. One instructor requires her students to take weekly computerized tests over the reading. Outside of the tests, the instructor also requires a research project in which students must keep field notes of their observations of a sociological concept in process.

Law, Joe. “Uncritical `Critical Thinking’: Reexamining Current Paradigms.” no citation. Possibly part of a workshop.

The problem with current instruction in composition in critical thinking is that it separates factual content from thinking, and tends to treat critical thinking as if it were a mechanistic skill. Current approaches may deal with formal/informal logic issues, but shows examples of logic fallacies, rather than the thought processes which led to them. Overviews the major approaches to teaching critical thinking and gives suggestions for overcoming their limitations.

McPeck, John E. “The Meaning of Critical Thinking.” Critical Thinking and Education . New York: St. Martin Press, n.d. 1- 23.

Defines critical thinking as thinking with skepticism about a subject or field. Requires that the thinker have the skills associated with practitioners in that field. Critical thinking can include certain aspects of problem solving and various skills. Argues that critical thinking can be taught using drills and practice, but not with just any drills–only drills that encourage the use of critical thinking. Students must be motivated to use their critical thinking skills.

Moll, Michael B., and Robert D. Allen. “Developing Critical Thinking Skills in Biology.” Journal of College Science Teaching (November 1982): 95- 98.

Describes efforts of biology faculty at West Virginia University to teaching critical thinking skills to introductory biology students. Uses video and discussion during class to enable students to apply concepts as they learn them; derive concepts from observations and data; and practice scientific processes. Presents assessment of the program, including data on improvement in students’ critical thinking skills pretest/posttest.

Nelson, Craig E. “Critical Thinking and Collaborative Learning.” New Directions for Teaching and Learning 59 (Fall 1994): 45-58.

Nelson introduces key aspects of the pedagogy of critical thinking and their relationships with collaborative learning. He suggests that it is important to learn how to explain why incorrect responses occur, in addition to providing the disciplinary expectations of a subject. Students need to move beyond a dualistic approach (yes/no answers) or a multiplistic approach (all answers are equally valid) to one of contextual relativism, where they learn the criteria for judging alternatives in a specific discipline. Nelson includes some examples of in-class exercises to accomplish this level of critical thinking.

Nelson, Craig E. “Skewered on the Unicorn’s Horn: The Illusion of Tragic Tradeoff Between Content and Critical Thinking in the Teaching of Science.” Materials for IU Teaching Resources Center workshop, February 4, 1991.

Presentation by Craig Nelson on the Perry scale, critical thinking in science and how to foster it, and how to use small group discussion fruitfully.

Nelson, Craig E. Fostering Critical Thinking and Mature Valuing Across the Curriculum: Comments & Conversation” Work in progress.

This document is an outline of a workshop presented at Indiana University Bloomington. It covers four modes of thinking ranging from fact recognition to contextual reasoning, with different transitional stages listed. Nelson includes some brief references.

Olson, Carol Booth. “The Thinking/Writing Connection.” Developing Minds: A Resource Book for Teaching Thinking . Ed. Arthur L. Costa . Alexandria, VA: Association for Supervision and Curriculum Development, 1985. 102- 107.

Connects writing and thinking processes. Presents a lesson plan to be used at grade-school level that supposedly encourages students to use all levels of thinking (knowledge, comprehension, application, analysis, synthesis, evaluation) and all parts of the writing process (prewriting, precomposing, writing, sharing, revising, editing, evaluation).

Paul, Richard. “Teaching Critical Thinking in the ‘Strong’ Sense: A Focus on Self-Deception, World Views, and a Dialectical Mode of Analysis.” No citation. 2-7.

Discusses how not to teach critical thinking (as a set of technical skills without larger contextual issues), and how to teach critical thinking. Argues that critical thinking needs to be taught in a dialectical or dialogic way–as arguments in relation to counterarguments. Lists means of evaluating a course on critical thinking taught in this way, and some “basic theoretic underpinnings” for such a course. Argues that multi-categorical ethical issues are ideal for teaching critical thinking.

A basic overview of the Perry scheme of intellectual development of college students. Also discusses some research done on the scheme, and some efforts at changing teaching.

Smith, Raymond. “Sequenced Microthemes: A Great Deal of Thinking for Your Students, and Relatively Little Grading for You.” Teaching Resources Center Newsletter .

This article responds to a Campuswide Writing Program survey of nearly 300 faculty members about the degree of writing used in their courses. While the motivations for assigning writing varies widely, nearly all of the respondents demand writing assignments from their students, although instructors cite that the time involved in grading is a major drawback. The use of sequenced micro-themes, however, allows instructors to foster critical thinking skills or other abilities in their students without adding an inordinate amount of time in grading. Smith includes two different sequences of assignments–one from his Shakespeare course and the other from a journalism course–designed to enable students to grasp important concepts and become prepared for later, more difficult work.

Slattery, Patrick. “Encouraging Critical Thinking: A Strategy of Commenting on College Papers.” College Composition and Communication 41 (October 1990): 332-335.

Suggests types of comments that can be made on student papers to encourage critical thinking: a support response and a challenge response.

Tallman, Julie. “Connecting Writing and Research through the I-Search Paper: A Teaching Partnership between the Library Program and Classroom.” Emergency Librarian 23.1 (September 1995): 20-23.

This article describes the collaboration between a high school English teacher and a librarian in doing a process-oriented research project called the I-Search paper. This process allows students to define their own research topics and reflect on the strategies used to gather and organize information at each step of the process. I-Search emphasizes interpretation over regurgitation of findings. The article also includes some sample prewriting exercises and journal prompts to use with students.

Thoma, George A. “The Perry Framework and Tactics for Teaching Critical Thinking in Economics.” Journal of Economic Education 42 (1993): 128-136.

Offers strategies for nudging student development within the Perry scheme of intellectual development. The underlying principles for these strategies rest in Craig Nelson’s work on transitioning between different modes of thinking.

Thompson, Jan C. “Beyond Fixing Today’s Paper: Promoting Metacognition and Writing Development in the Tutorial through Self-Questioning.” The Writing Lab Newsletter 23.6 (1999): 1-6.

Although open-ended questions are generally preferred by composition specialists, these types of questions are particularly important within the context of tutoring students with learning disabilities. These students tend not to strategize without outside, explicit direction, but open-ended questions help these students develop metacognitive skills through active learning. Socratic discussions, outlines, and the five Ws are discussed, along with rhetorical modes. Self-cuing is another important part of this type of tutorial, especially LD students.

Turner, Michele. “Writing Across the Curriculum and Critical Thinking Skills in Nursing 414.” Writing Across the Curriculum . 9 (May 1998): 1-2.

Describes three assignments used to develop critical thinking skills in a course entitled, “Applying Neuroscience Nursing Principles to Practice.” “Development of a Concept” requires students to use journals to develop a historical review of the evolution of a neuroscience nursing concept. Student-developed questions relating to the daily topic and based upon the preparatory reading, and a textbook exercise meant to stimulate students to become more critical readers as they search for outdated or inaccurate information in the assigned textbook.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Table of contents

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

29 Critical Thinking Skills

Introduction, what you’ll learn to do: d efine critical thinking and its role in your education.

The essence of the independent mind lies not in what it thinks, but in how it thinks. —Christopher Hitchens, author and journalist

By the end of this section, you will be able to explain critical thinking, describe the role that logic plays in critical thinking, and identify how critical thinking skills can be used to evaluate information. You’ll also define information literacy and describe how critical thinking skills can be used to solve problems by identifying strategies for developing yourself as a critical thinker.

Critical Thinking

Learning objectives.

• Define critical thinking

Thinking comes naturally. You don’t have to make it happen—it just does. But you can make it happen in different ways. For example, you can think positively or negatively. You can think with your heart and you can think with rational judgment. You can also think strategically and analytically, and mathematically and scientifically. These are a few of the multiple ways in which the mind can process thought.

What are some forms of thinking you use? When do you use them and why?

As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important thinking skills is critical thinking. Critical thinking is important because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It’s a “domain-general” thinking skill—not a thinking skill that’s reserved for one subject alone or restricted to a particular subject area. Critical thinking is used in every domain, from physics to auto mechanics. It is often employed to problem solve when we are puzzled by something or to reveal that there is an error in common ways of thinking about things. Thus, critical thinking is essential for revealing biases.

For example, Galileo used a common form of reasoning called reductio ad absurdum (Latin for “reduce to absurdity) to show that the physics of his day was mistaken. People at that time believed that the heavier something was, the faster it would fall. Galileo knew this common conception was mistaken and he proved it both empirically and conceptually. Here is how he proved it conceptually. Suppose you have two objects, one heavier (call it B) than the other (call it A). Suppose the heavier object falls faster. When you put the lighter object under the heavier object (c), the lighter object should slow down the heavier object. On the other hand, gluing together both objects results in a heavier object (c), which should fall even faster than (b). See diagram here . The contradiction proves by reductio ad absurdum that the assumption must be false. This is just one example, but the form of reasoning (reductio ad absurdum) is the same across every domain—from science to religion to auto mechanics. The form of reasoning is just this: assume for the sake of the argument that A is true. If we can then show that A leads to a contradiction (literally where two statements are asserted that cannot possibly be true), then we prove that A is false.

Great leaders have highly attuned critical thinking skills, and you can too. In fact, you probably have a lot of these skills already. Of all your thinking skills, critical thinking may have the greatest value.

What Is Critical Thinking?

Critical thinking is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like, “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions, rather than simply memorizing facts or blindly accepting what you hear or read.

Imagine, for example, that you’re reading a history textbook. You wonder who wrote it and why because you detect certain biases in the writing. You find that the author has a limited scope of research focused only on a particular group within a population. In this case, your critical thinking reveals that there are other sides to the story.

Who are critical thinkers, and what characteristics do they have in common? Critical thinkers are usually curious and reflective people. They like to explore and probe new areas and seek knowledge, clarification, and new solutions. They ask pertinent questions, evaluate statements and arguments, and they distinguish between facts and opinions. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit a lack of knowledge or understanding when needed. They are open to changing their mind. Perhaps most of all, they actively enjoy learning, and seeking new knowledge is a lifelong pursuit.

This description may well be you!

No matter where you are on the road to being a critical thinker, you can always more fully develop and finely tune your skills. Doing so will help you develop more balanced arguments, express yourself clearly, read critically, and glean important information efficiently. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching. With critical thinking, you become a clearer thinker and problem solver.

The following video from Lawrence Bland presents the major concepts and benefits of critical thinking.

You can view the transcript for “Critical Thinking.wmv” here .

Supporting Claims with Evidence

Thinking and constructing analyses based on your thinking will bring you in contact with a great deal of information. Some of that information will be factual, and some will not be. You need to be able to distinguish between facts and opinions so you know how to support your arguments. Begin with the following basic definitions:

• Fact: a statement that can be supported by objective evidence such as observation, argument, or research.
• Opinion: a statement whose truth depends on someone’s desire(s) rather than objective evidence. Opinions that cannot be supported by objective evidence are at most subjectively true.

Of course, the tricky part is that most people do not label statements as fact and opinion, so you need to be aware and recognize the difference as you go about honing your critical thinking skills.

You probably have heard the old saying “Everyone is entitled to their own opinions,” which may be true, but conversely not everyone is entitled to their own facts. Facts are true for everyone, not just those who want to believe in them. For example, “mice are mammals”  is a fact since it has been established by scientific research. In contrast, “mice make the best pets” is an opinion (since best means whatever one likes the best—and that is a matter of one’s subjective desires).

Facts vs. Opinion

Determine if the following statements are facts or opinions based on just the information provided here, referring to the basic definitions above. Some people consider scientific findings to be opinions even when they are convincingly backed by reputable evidence and experimentation. However, remember the definition of fact—verifiable by research or observation. Think about what other research you may have to conduct to make an informed decision.

• Oregon is a state in the United States. (How would this be proven?)
• Beef is made from cattle. (See current legislation concerning vegetarian “burgers.”)
• Increased street lighting decreases criminal behavior. (What information would you need to validate this claim?)
• In 1952, Elizabeth became Queen of England. (What documents could validate this statement?)
• Oatmeal tastes plain. (What factors might play into this claim?)
• Acne is an embarrassing skin condition. (Who might verify this claim?)
• Kindergarten decreases student dropout rates. (Think of different interest groups that may take sides on this issue.)
• Carbohydrates promote weight gain. (Can you determine if this is a valid statement?)
• Cell phones cause brain tumors. (What research considers this claim?)
• Immigration is good for the US economy. (What research would help you make an informed decision on this topic?)

Defending against Bias

Once you have all your information gathered and you have checked your sources for currency and validity, you need to direct your attention to how you’re going to present your now well-informed analysis. Be careful on this step to recognize your own possible biases (metacognition). Facts are verifiable statements; opinions are statements without supporting evidence. Stating an opinion is just that. You could say, “Blue is the best color,” and that would be your opinion. In contrast, suppose you were to conduct research and find the use of blue paint in mental hospitals reduces patients’ heart rates by twenty-five percent and contributes to fewer angry outbursts from patients. In that case, the statement “blue paint in mental hospitals reduces patients’ heart rate by twenty-five percent” would be a fact supported by objective evidence.

Not everyone will accept your analysis, which can be frustrating. Most people resist change and have firm beliefs on both important issues and less significant preferences. With all the competing information surfacing online, on the news, and in general conversation, you can understand how confusing it can be to make any decisions. Look at all the reliable, valid sources that claim different approaches to be the best diet for healthy living: ketogenic, low-carb, vegan, vegetarian, low fat, raw foods, paleo, Mediterranean, etc. All you can do in this sort of situation is conduct your own serious research, check your sources, and write clearly and concisely to provide your analysis of the information for consideration. You cannot force others to accept your stance, but you can show your evidence in support of your thinking, being as persuasive as possible without lapsing into your own personal biases.

A Model for Critical Thinking

Students, scholars, and organizations looking for a framework for critical thinking frequently rely on the RED Model. The RED Model was developed by Pearson and consists of three components, (1) Recognize Assumptions; (2) Evaluate Arguments; (3) Draw Conclusions. The video below provides more information on the RED Model. [1]

• Describe the role that logic plays in critical thinking

Critical Thinking and Logic

Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly held belief or a new idea. With critical thinking, anything and everything is subject to question and examination for the purpose of logically constructing reasoned perspectives.

What Is Logic, and Why Is It Important in Critical Thinking?

The word logic comes from the ancient Greek word  logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and reasoning and strives to distinguish between good and bad reasoning. Using logic, you can evaluate ideas or claims people make, make good decisions, and form sound beliefs about the world. [2]

Critical thinking involves reflective thinking, considering bias, and remaining open-minded and curious. It also demands the intellectual rigor to deconstruct and evaluate claims made by others while also making sound and strong arguments, ourselves. Logic is the study and evaluation of arguments to distinguish good reasoning from bad. When using logic in critical thinking, you will consider the logical structure in order to evaluate its quality. In the next section, we will explore what logical structure is.

Logical Structure

Suppose I argue as follows: if it is raining, then the ground is wet; but since it is not raining, it follows that the ground is not wet. This is an argument whose conclusion is the statement “the ground is not wet.” The two premises of the argument are the conditional statement “if it is raining, then the ground is not wet” and the statement “it is not raining.”  We can rewrite the argument to clearly show each of the statements—the two premises and the conclusion—like this:

• If it is raining, then the ground is wet.
• The ground is not wet.
• Therefore, it is not raining.

This example is a valid argument. A valid argument is an argument whose premises guarantee the truth of the conclusion. In other words, a valid argument is one such that on the assumption of the truth of the premises, it is impossible for the conclusion to be false. Think about the previous argument. Can you see that if we accept the two premises (lines 1 and 2) as true, then we must logically accept the conclusion (line 3) to be true? Valid arguments are the gold standard of reasoning in logic—it is what all arguments aspire to be. When you have constructed a valid argument, no one can argue with your reasoning (although they can still disagree with you regarding whether your premises are true). What is interesting about the concept of logical validity is that an argument can be valid (i.e., the reasoning can be good) even if the premises are obviously false or absurd. For example, consider this (slightly altered) argument from a scene in Monty Python and the Holy Grail :

• If this woman weighs the same as a duck, then she is is made of wood.
• Everything made of wood is a witch.
• This woman does weigh the same as a duck.
• Therefore, this woman is a witch.

Clearly, the first two premises of this argument (lines 1 and 2) are false. However, if we hold them (and also the premise in line 3) true, then the conclusion follows logically. That is, this argument is a valid argument. Think about the logic of this argument for a second. If we assume that lines 1 and 3 are true, then it follows that the woman is made of wood.  And if that is true then by line 2, it follows that she is a witch, which is the conclusion stated in line 4. This silly argument illustrates that logic is first and foremost about the relationship between premises and conclusion, not the actual truth of the premises. Whether or not the premises of an argument are true is often a matter that is outside logic. For example, if one of the premises of an argument were the statement “some mammals do not give live birth,” then logic alone cannot help you figure out whether that is true. For that you need another disciplines: biology.

Let’s return to the first argument for a second to illustrate what logical structure is. That argument has a certain structure that looks like this:

• If A then B.
• Therefore, not A.

What is interesting about logic is that once we can see the form of an argument, then we can automatically know that the argument is valid without even considering or thinking about the content of the argument. Any argument that has a valid structure is a valid argument. Logic is (in part) the study of these structures. The structure that I have just identified has a name: modus tollens (which in Latin means “way of denying,” since the second premise contains a negation, “not”).  Lines 1 and 3 of the Monty Python argument above also contain a valid structure that looks like this:

• Therefore, B.

That argument form is called modus ponens (which in Latin means “way of affirming”).

There are many different valid argument structures; however, this is not a logic course, so we will not consider them all.  The important thing to understand is that logic concerns the strength of the relationship between the premises and the conclusion, and the goal in constructing arguments is to construct valid arguments. Again, valid arguments are such that the premises of the argument leave no possibility that the conclusion could be false. In contrast, invalid arguments are ones where the premises do leave open the possibility that the conclusion is false. In other words, the premises do not imply the truth of the conclusion. If an argument is invalid, then we should be able to give a counterexample that proves the argument is invalid. A counterexample is simply a description of a possible scenario where the premises are true and yet the conclusion is false. Let’s look at an example.

• If the train is late, Shondra is angry.
• Shondra is angry.
• Therefore, the train is late.

If we assume the premises (lines 1 and 2) are true, is it possible for the conclusion to be false? If so, then this would show the argument is invalid. Here’s a hint if you can’t already see the answer: might Shondra be angry for some other reason and yet the train still be on time? Suppose Shondra is angry because she spilled coffee on her favorite pants. If so, then it could still be the case that any time the train is late, Shondra is angry but on this occasion, the train is actually on time. Given this scenario, let’s check line by line the argument. In this scenario are the premises true? Yes, they are—premise 1 is true since Shondra would have been angry if the train were late even though the train wasn’t late and premise 2 is true since Shondra is angry because of the coffee spill. And yet the conclusion is false since the train is not late in this scenario. Thus, we have given a counterexample: we have specified a scenario where the premises are true and yet the conclusion is false. And that means the argument is invalid.

Whereas the gold standard of deductive arguments is validity (as discussed in the last section), the standard of inductive arguments is something less than validity. A strong inductive argument is typically called a cogent argument. It is important to understand the difference between deductive and inductive arguments because you need to understand what kind of argument you are trying to make or evaluate. The main difference between inductive and deductive arguments is that whereas deductive arguments seek to establish their conclusions with absolute certainty, inductive arguments only seek to establish their arguments with a high degree of probability. Here’s an example of a strong inductive argument:

• All ravens that have ever been observed anywhere in the world have been black.
• Therefore, all ravens are black.

Notice that this argument doesn’t quite obtain the standard of validity. It is possible that there is a non-black raven somewhere in the world that hasn’t been observed. But even if that is a possibility, it seems that the “all ravens are black” conclusion is still highly likely, given the amount of confirmation that the claim possesses (i.e., the number of ravens that have been observed and that all of them have been black).

Unlike deductive arguments, there is no inductive form that is strong. Any inductive argument could be strong or weak depending on the details of the argument. In contrast, deductive arguments have valid logical structures such that any argument that possesses an inductive form is thereby a valid argument, regardless of the topic of the argument; meaning that to evaluate inductive arguments, we have to draw on our knowledge of how the world is. We can say a couple of things about strong inductive reasoning, but to further understand these concepts would require a course in logic and/or scientific reasoning. We will conclude this page with a few rules of thumb to keep in mind when it comes to inductive arguments:

• When making inductive generalizations (such as the ravens argument), make sure that the instances in your premises are not susceptible to any kind of sampling bias. For example, even if I have observed many black ravens, if I have only observed them in one part of the world, there is a good chance that my sample of ravens is not representative of all the ravens in the world.
• Many times inductive arguments depend on establishing correlations and we try to infer causation based on correlation. However, this inference must be done carefully. As the saying goes, correlation is not causation; a correlation is not sufficient to establish causation—just because A and B are strongly correlated, or tend to occur together, doesn’t mean that A caused B. To establish that causal claim would require both a plausible causal story we can tell and (ideally) further test to determine whether A really does cause B.
• Another common inductive argument is an analogical argument. Analogical arguments attempt to compare two different things (A and B) and argue that since they are similar in relevant respects, if A has a certain property (x), then B must have that property as well. The thing to be on the lookout for here is whether A and B really are similar in relevant respects; because if they aren’t, the logic of the analogical argument breaks down.

Evaluating Information

Learning outcomes.

• Describe how critical thinking skills can be used to evaluate information

Evaluating information can be one of the most complex tasks you will be faced with in college. But if you utilize the following four strategies, you will be well on your way to success:

• Read for understanding by using text coding.
• Examine arguments.
• Clarify thinking.
• Cultivate habits of mind.

Read for Understanding by Using Text Coding

When you read and take notes, use the text coding strategy. Text coding is a way of tracking your thinking while reading. It entails marking the text and recording what you are thinking either in the margins or perhaps on Post-it notes. As you make connections and ask questions in response to what you read, you monitor your comprehension and enhance your long-term understanding of the material. This kind of active reading is a kind of metacognition and is importantly different from more passive reading. You will get a lot more out of your reading if you read actively.

With text coding, mark important arguments and key facts. Indicate where you agree and disagree or have further questions. You don’t necessarily need to read every word, but make sure you understand the concepts or the intentions behind what is written. Feel free to develop your own shorthand style when reading or taking notes. The following are a few options to consider using while coding text.

Examine Arguments

When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and examine the hard facts. You can use the spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the hot end of an argument—feelings, beliefs, cultural influences, and societal influences. The cold end of an argument is the scientific influences.

The following video explains this strategy by describing a spectrum of examples involving culture, beliefs, and feelings as the hot end of the spectrum. Whereas scientific subjects such as geometry, physics, and biology are more on the cold side of this spectrum. Take notes about the examples of the spectrum of authority.

You can view the transcript for “Critical Thinking 101: Spectrum of Authority” here .

Clarify Thinking

When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this clarification well is mainly a process of asking and answering probing questions, such as the logic questions discussed earlier. Design your questions to fit your needs, but be sure to cover adequate ground. What is the purpose? What question are we trying to answer? What point of view is being expressed? What assumptions are we or others making? What are the facts and data we know, and how do we know them? What are the concepts we’re working with? What are the conclusions, and do they make sense? What are the implications?

Cultivate Habits of Mind

Habits of mind are the personal commitments, values, and standards you have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence, being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always questioning your own conclusions—in other words, developing an intellectual work ethic. Try to work these qualities into your daily life.

Students interested in practicing these habits of mind should explore the database Opposing Viewpoints which is available through the FSW library . This database provides viewpoint articles, as well as scholarly sources, on a wide variety of controversial topics. Reading and evaluating the arguments in viewpoint articles will allow students the opportunity to identify assumptions, recognize bias, evaluate source credibility and analyze arguments.

Problem-Solving with Critical Thinking

• Describe how critical thinking skills can be used in problem-solving

Most of us face problems that we must solve every day. While some problems are more complex than others, we can apply critical thinking skills to every problem by asking questions like, what information am I missing? Why and how is it important? What are the contributing factors that lead to the problem? What resources are available to solve the problem? These questions are just the start of being able to think of innovative and effective solutions. Read through the following critical thinking, problem-solving process to identify steps you are already familiar with as well as opportunities to build a more critical approach to solving problems.

Problem-Solving Process

Step 1: define the problem.

Albert Einstein once said, “If I had an hour to solve a problem, I’d spend 55 minutes thinking about the problem and five minutes thinking about solutions.”

Often, when we first hear of or learn about a problem, we do not have all the information. If we immediately try to find a solution without having a thorough understanding of the problem, then we may only be solving a part of the problem.  This is called a “band-aid fix,” or when a symptom is addressed, but not the actual problem. While these band-aid fixes may provide temporary relief, if the actual problem is not addressed soon, then the problem will continue and likely get worse. Therefore, the first step when using critical thinking to solve problems is to identify the problem. The goal during this step is to gather enough research to determine how widespread the problem is, its nature, and its importance.

Step 2: Analyze the Causes

This step is used to uncover assumptions and underlying problems that are at the root of the problem. This step is important since you will need to ensure that whatever solution is chosen addresses the actual cause, or causes, of the problem.

Asking “why” questions to uncover root causes

A common way to uncover root causes is by asking why questions. When we are given an answer to a why question, we will often need to question that answer itself. Thus the process of asking “why” is an   iterative process —meaning that it is a process that we can repeatedly apply. When we stop asking why questions depends on what information we need and that can differ depending on what the goals are. For a better understanding, see the example below:

Problem: The lamp does not turn on.

• Why doesn’t the lamp turn on? The fuse is blown.
• Why is the fuse blown? There was an overloaded circuit.
• Why was the circuit overloaded? The hair dryer was on.

If one is simply a homeowner or tenant, then it might be enough to simply know that if the hair dryer is on, the circuit will overload and turn off.  However, one can always ask further why questions, depending on what the goal is. For example, suppose someone wants to know if all hair dryers overload circuits or just this one. We might continue thus:

• Why did this hair dryer overload the circuit? Because hair dryers in general require a lot of electricity.

But now suppose we are an electrical engineer and are interested in designing a more environmentally friendly hairdryer. In that case, we might ask further:

• Why do hair dryers require so much energy?

As you can see from this example, what counts as a root cause depends on context and interests. The homeowner will not necessarily be interested in asking the further why questions whereas others might be.

Step 3: Generate Solutions

The goal of this step is to generate as many solutions as possible. In order to do so, brainstorm as many ideas as possible, no matter how outrageous or ineffective the idea might seem at the time. During your brainstorming session, it is important to generate solutions freely without editing or evaluating any of the ideas. The more solutions that you can generate, the more innovative and effective your ultimate solution might become upon later review.

You might find that setting a timer for fifteen to thirty minutes will help you to creatively push past the point when you think you are done. Another method might be to set a target for how many ideas you will generate. You might also consider using categories to trigger ideas. If you are brainstorming with a group, consider brainstorming individually for a while and then also brainstorming together as ideas can build from one idea to the next.

Step 4: Select a Solution

Once the brainstorming session is complete, then it is time to evaluate the solutions and select the more effective one.  Here you will consider how each solution will address the causes determined in step 2. It is also helpful to develop the criteria you will use when evaluating each solution, for instance, cost, time, difficulty level, resources needed, etc. Once your criteria for evaluation are established, then consider ranking each criterion by importance since some solutions might meet all criteria, but not to equally effective degrees.

In addition to evaluating by criteria, ensure that you consider the possibilities and consequences of all serious contenders to address any drawbacks to a solution. Lastly, ensure that the solutions are actually feasible.

Step 5: Put Solution into Action

While many problem-solving models stop at simply selecting a solution, in order to actually solve a problem, the solution must be put into action. Here, you take responsibility to create, communicate, and execute the plan with detailed organizational logistics by addressing who will be responsible for what, when, and how.

Step 6: Evaluate progress

The final step when employing critical thinking to problem-solving is to evaluate the progress of the solution. Since critical thinking demands open-mindedness, analysis, and a willingness to change one’s mind, it is important to monitor how well the solution has actually solved the problem in order to determine if any course correction is needed.

While we solve problems every day, following the process to apply more critical thinking approaches in each step by considering what information might be missing; analyzing the problem and causes; remaining open-minded while brainstorming solutions; and providing criteria for, evaluating, and monitoring solutions can help you to become a better problem-solver and strengthen your critical thinking skills.

Information Literacy

• Define information literacy

When conducting any type of thinking, you need to have a firm grasp of information literacy , or knowing how to access the sources you may need. Practicing good information literacy skills involves more than simply using a search engine such as Google, although that could be a starting point. You also engage in creative thinking (e.g., generating topics to research), analytical thinking (e.g., reading and examining the parts of sources), and critical thinking (e.g., evaluating sources for accuracy, authority, etc.). Then there is synthesis that is used when incorporating multiple sources into a research project. Information literacy utilizes all the necessary thinking skills. If you saw the name of a person on the cover of a magazine, for instance, you might assume the person did something important to merit the attention. If you were to google the person’s name, you would instantly need to use context clues to determine if the information your search produced is actually about your person and not someone else with the same or a similar name, whether the information is accurate, and if it is current. If it is not, you would need to continue your research with other sources.

How Information Becomes Knowledge

Life is a series of problems needing solutions. We need to find information that matters and then discover why it matters. Curiosity, then, is a response to an environment of exploration, manifesting in wanting to know why or how. How do you make sense of the world? How does information translate to knowledge? Connecting ideas, thinking critically, acting responsibly, and communicating effectively are all essential to lifelong learning and active engagement in today’s world. You need to become proficient, ethical users and producers of information in a globally connected world. It is important to be able to reason, manage resources, work productively with others, acquire and evaluate information effectively, organize information, interpret and communicate information, and work with an ever-evolving variety of technologies. In other words, you need to become information-savvy consumers and producers. You need to be able to adapt to, understand, evaluate, and make use of technology so you can be citizens that shape our society, rather than being its pawns. What you learn is often what you will communicate to others.

What Is Information Literacy?

Human beings are passionate, curious, and always seeking to connect with each other and make sense of things. Learning is more effective when new information is meaningful and linked to some personal experience or prior knowledge. Learning is about both context and content. It is necessary to learn how to assess, evaluate, and connect in order to make information become knowledge. Information literacy skills are the hallmark of the ability to do research. What is important is for you to learn how to find information that matters and then figure out why it might matter.

“Information literacy is the set of integrated abilities encompassing the reflective discovery of information, the understanding of how information is produced and valued, and the use of information in creating new knowledge and participating ethically in communities of learning” (ACRL, 2015).

Information literacy is a link between the life experiences of you as a student, the academic world of scholarship, and the postcollege real world of application of learning. An information-literate person has the ability to ask questions and knows the difference between ignorance and understanding. (When do I need information?) Information literacy builds a lifelong ability to determine where information is kept (Where is the best place to find this?) and in what forms knowledge is stored (Which knowledge products will likely have what I need?).

Information literacy relies on the use of a critical mind to discern credible from not credible, and valid from not valid. It is actually the core of the first-year experience. Information literacy lasts while the specifics of particular courses fade over time. After all, the nature of research, the core of higher education, is a learning process: “How do I learn about something?” Communication skills are essential to your ability to both learn and share what you’ve learned.

Verifying Source Validity

We need information almost all the time, and with practice, you’ll become more and more efficient at knowing where to look for answers on certain topics. As information is increasingly available in multiple formats, not only in print and online versions but also through audio and visual means, users of this information must employ critical thinking skills to sift through it all.

In today’s information environment, what would be the best way to find valid information about climate change? Would it be Wikipedia, NASA, a printed encyclopedia from 1985, or a report from a political campaign?

If you chose any answer except the NASA website, can you see how the other answers may have a vested interest in encouraging readers to believe a particular theory? The encyclopedia may not intentionally attempt to mislead readers; however, the write-up is not current. And Wikipedia, being an open-source site where anyone may upload information, is not reliable enough to lend full credence to the articles. A professional, government organization that does not sell items related to the topic and provides its ethics policy for review is worthy of more consideration and research. This level of critical thinking and examined consideration is the only way to ensure you have all the information you need to make decisions.

You likely know how to find some sources when you conduct research. And remember—we think and research all the time, not just in school or on the job. If you’re out with friends and someone asks where to find the best Italian food, someone will probably consult a phone app to present choices. This quick phone search may suffice to provide an address, hours, and possibly even menu choices, but you’ll have to dig more deeply if you want to evaluate the restaurant by finding reviews, negative press, or personal testimonies.

Why is it important to verify the validity of sources? The words we write (or speak) and the sources we use to back up our ideas need to be true and honest, or we would not have any basis for distinguishing facts from opinions that may be, at the least damaging level, only uninformed musings but, at the worst level, intentionally misleading and distorted versions of the truth. Maintaining strict adherence to verifiable facts is a hallmark of a strong thinker.

You probably see information presented as fact on social media daily, but as a critical thinker, you must practice validating facts, especially if something you see or read in a post conveniently fits your perception. You may be familiar with the Facebook and Instagram hoaxes requiring users to copy and paste a statement that they will not grant permission for these social media sites to make public the content from their private pages. Maybe you’ve seen any number of posts and memes that inaccurately associate famous people with memorable quotations. We may even allow ourselves to believe inaccurate claims as truth when we experience different emotions including anger, fear, or loneliness; we want to believe a claim is true because it aligns with how we are feeling, regardless of any verifiable source. Be diligent in your critical thinking to avoid misinformation!

Determining how valid a source is typically includes looking into the author’s credentials, experience, and status in the discipline; the actual content of the source material; any evidence the source presents as support; and whether any biases exist that may make the source questionable. Once you know who controls the content of the source you’ve chosen, you need to determine what biases or special interests the site or article may exhibit.

With the proliferation of information in the digital age, it is also important to understand that authority is constructed and contextual (ACRL, 2015). This statement means that in addition to the traditional understanding of authority based on credentials, experience, and status in a discipline, authority can be constructed to better reflect the expertise of a wider community. This means that a blog post may contain the same level of innovative and authoritative information that is found in a traditional, peer-reviewed scholarly journal article. It is important to confirm the accuracy of the information through a clear evaluation process. The accuracy of information can be independently confirmed through multiple sources ensuring that each source is not citing the same source of information.

Recognize information bias

Reflect on what bias the following sites may have. Without consulting the Internet, write one to two sentences on what ideas the following organizations may present. After you consider these organizations on your own, conduct a search and see if you were accurate in your assumptions about the entities.

• National Dairy Council
• Yoga Society
• People for the Ethical Treatment of Animals (PETA)
• The American Medical Association

Whatever you write or declare based on sources should be correct and truthful.  Reliable sources  present current and honest information backed up with evidence you can check. Any source that essentially says you should believe the source “because I said so” isn’t a valid source for critically thinking, information-literate individuals.

Evaluating books, articles, and websites for validity presents different challenges. For books and scholarly articles, in print or online, you can typically establish if the source is current and from a reputable publisher or organization with information on the copyright page or journal publication information.

As you think about the information bias that may exist in your sources, it is also important to understand your own biases when conducting research. Confirmation bias happens when you only look for sources that confirm and prove your predetermined conclusions instead of looking for a range of information to not only challenge your assumptions but also to support your analysis of reputable information.

For a website, you should determine who owns this site. Is it a professional organization such as the American Medical Association? You can usually find this info in the  About  section of the site or in a copyright designation near the end of the landing page. Domain names can help you determine the purpose of the site, but you shouldn’t rely solely on this website marker.

Bias in the News: Activity

Pick one news source from each column below and read an article about the same event from the two news sites you picked.

Do you notice any differences in their reporting? Write down your answers to the following questions:

• What is the main claim of the article on each news site?
• What assumptions does each article make?
• What conclusions does each article draw?
• Are there any big differences between how the two news sites report on the same event? What are they?

Finally, reflect on where you get your news. Why do you use those sources? What are you looking for when you’re choosing your news sources?

Students interested in building information literacy skills can take advantage of the various workshops offered by FSW’s knowledgeable librarians. See Bucs Corner for upcoming workshop opportunities. Another option is to complete the Library Research Tutorial on your own time. Completing the tutorial online or participating in a workshop (in person or on Zoom) will also fulfill a GPS requirement.

Resources for Thinking

When you look into books, articles, and documentaries on thinking, you will find plenty of choices. Some books or articles on thinking may seem to apply only to a narrow group of readers, such as entrepreneurs or artists. For example, the audiences for these two books about thinking seem highly selective: Carl Sagan’s  The Demon-Haunted World: Science as a Candle in the Dark  may be mostly directed to the science community, and James Loewen’s  Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong  is likely of interest primarily to historians. And some chapters may focus specifically on those groups; however, most texts on thinking are also applicable to other disciplines. You may have to work a bit harder to find a common ground or generate your own examples that explain the concepts from the book, but you can still reap benefits from understanding different perspectives. Don’t immediately disregard a book or article just because it doesn’t seem to fit your thinking perspective on the surface; dig a bit more deeply to see what you can learn. Remember, being open-minded and considering as many alternate approaches as possible are two hallmarks of critical thinking.

Finding Print and Online Resources

When you need to research a topic, you probably start with a search engine. That search can be helpful, but can easily lead you down incorrect paths and waste time. Use advanced searches, filters, and other means to target your results more specifically. However, don’t limit yourself to just Internet sources; print journals, books, and articles are still significant sources of information.

Your college may have access to extensive stores of subscription-based site content, photos, videos, and other media through its library, providing more than enough information to start researching and analyzing any topic. Depending on the specific database and school, you may be able to access some of these resources remotely; others may require you to visit the library in person. Remember, when you are gathering and arranging pieces of information, keep track of the source and the URL so that you can both cite it correctly and return to learn more if needed.

The FSW library will provide you with access to print sources but also sources available online through databases. These sources provide you with access to books, magazine articles, newspaper articles, journal articles, industry reports, and a range of videos, photographs, and primary sources. The FSW Library Research Tutorial provides valuable instruction for students on research skills in general and how to use FSW’s Library resources and databases. While these sources are excellent to use when conducting research, there is a range of other sources you can use. Some more general places to explore educational, inspirational, and thought-provoking material follow:

• Exploring  the TED website  is worth a few minutes of time. There you’ll find videos (limited to 18 minutes) of speaking demonstrations by diverse experts in fields covering all disciplines. If you are in an exploratory phase of your thinking and researching, you can scan the TED Talk topics related to your interest area.
• You may be familiar with the Khan Academy, created in 2008 by Salman Khan, as an online learning resource for students and teachers containing tutorials, videos, and practice sets in various subjects from science and mathematics to grammar lessons.
• Massive Open Online Courses (MOOCs) provided by Coursera, Udemy, and Udacity, provide learners and thinkers the chance to take courses, attend webinars and discussions, and learn about a large number of subjects, often free of charge. Much of the content is provided by major universities, and the courses are often facilitated by faculty.
• For-profit companies and nonprofit groups such as the Foundation for Critical Thinking (FCT) can also help you hone your thinking. The FCT presents materials, seminars, and conferences to help people think with “clarity, relevance, logic, accuracy, depth, significance, precision, breadth, and fairness.”

Creating a System for Managing Resources

You could have all the money (or time or cars or great ideas) in the world, but that won’t do you any good if you haven’t also created a system for managing all your resources. In the same way, you might feel overwhelmed with all the choices when a waiter gives you a book-sized menu with hundreds of options, you can stall your thinking if you don’t have an effective and efficient way to access all the great articles, websites, books, podcasts, webinars, and other idea resources you can amass for the life of a project or during a college course or for a life event.

Systems to manage your ideas and thoughts don’t need to be elaborate. The best idea-management system is the one that gets used, so you need to be comfortable with what all is involved in managing these thoughts. Keep in mind, once you get into the swing of researching for and keeping good ideas, you’re going to end up with resources in many different formats. Gone are the days when one shelf of a bookcase near your desk could contain all your thinking resources on a topic. You may still find books, so you don’t need to discard the bookcase just yet, but very likely, you’ll also have online resources including search results, document files, websites, blogs, audio files, videos, and more. You can use filing folders, binders, online folders, boxes, or computer systems to organize your ideas.

A word about stacking papers and clutter: don’t. Clutter impedes creativity, steals focus, and represents procrastination. Fight the temptation to allow clutter to overwhelm your projects and workspace. File or trash anything you are not using right at the moment; this daily practice will save you a tremendous amount of time that you could waste looking for papers or articles you saved for later review.

Like physical clutter, a messy online environment can stall productivity and clear thinking. One key to effective information and idea management is a simple, consistent labeling system. Some companies call this a  naming protocol or naming convention,  a standard way all online files, folders, and drives are labeled for easier retrieval and long-term storage. If you don’t think through a file name with this forward-looking approach and then you don’t access that file for several months, you aren’t likely to remember which file is which, and you may end up wasting valuable time opening random files in an attempt to find the one you need. This isn’t a very efficient way to operate, and in some work environments would not be acceptable on large-scale and important projects. For example, if you were taking an upper-level literature course studying poetry and remember you filed an excellent summary of one of the poems a few years earlier in your freshman composition class, you won’t be too happy when you have seventy-eight documents called  Notes.  Great idea—lousy document/idea management system.

If your searches will take place on multiple devices—a laptop and a tablet, for example, you could use a notetaking app such as Evernote, which contains a wealth of organizational tools and has various levels of access. You can access the same note regardless of where you’re searching. In the same way, you could even use a series of Google Docs or Sheets, as long as you consider the file naming and organizational conventions mentioned above. For example, if you needed to put together a research paper requiring twenty data sources, you could use a spreadsheet to keep track of the source article name, author, topics, potential data points you plan to use, the source, and the URL. Even if you didn’t incorporate everything into the final paper, such a method would save you a lot of time trying to track down small pieces of information. (The sheet would also be a great reference when you write your bibliography.)

Finding print and online sources demands a great deal of time and effort. Understanding how different approaches to thinking are appropriate for various situations as you research will help you be more creative and critical as you identify and verify your sources.

Developing Yourself as a Critical Thinker

• Identify strategies for developing yourself as a critical thinker

Critical thinking is a desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and hatred for every kind of imposture. —Francis Bacon, philosopher

Critical thinking is a fundamental skill for college students, but it should also be a lifelong pursuit. Below are additional strategies to develop yourself as a critical thinker in college and in everyday life:

• Reflect and practice : always reflect on what you’ve learned. Is it true all the time? How did you arrive at your conclusions?
• Use wasted time : It’s certainly important to make time for relaxing, but if you find you are indulging in too much of a good thing, think about using your time more constructively. Determine when you do your best thinking and try to learn something new during that part of the day.
• Redefine the way you see things : It can be very uninteresting to always think the same way. Challenge yourself to see familiar things in new ways. Put yourself in someone else’s shoes and consider things from a different angle or perspective. If you’re trying to solve a problem, list all your concerns: what you need in order to solve it, who can help, what some possible barriers might be, etc. It’s often possible to reframe a problem as an opportunity. Try to find a solution where there seems to be none.
• Analyze the influences on your thinking and in your life : Why do you think or feel the way you do? Analyze your influences. Think about who in your life influences you. Do you feel or react a certain way because of social convention or because you believe it is what is expected of you? Try to break out of any molds that may be constricting you.
• Express yourself : Critical thinking also involves being able to express yourself clearly. Most important in expressing yourself clearly is stating one point at a time. You might be inclined to argue every thought, but you might have a greater impact if you focus just on your main arguments. This focus will help others to follow your thinking clearly. For more abstract ideas, assume that your audience may not understand. Provide examples, analogies, or metaphors where you can.
• Enhance your wellness : It’s easier to think critically when you take care of your mental and physical health. Try taking ten-minute activity breaks to reach thirty to sixty minutes of physical activity each day. Try taking a break between classes and walk to the coffee shop that’s farthest away. Scheduling physical activity into your day can help lower stress and increase mental alertness.
• Strategically plan your hardest work: Do your most difficult work when you have the most energy. Think about the time of day you are most effective and have the most energy. Plan to do your most difficult work during these times. And be sure to reach out for help. If you feel you need assistance with your mental or physical health, talk to a counselor or visit a doctor.

3 Core Critical Thinking Skills Every Thinker Should Have

Critically thinking about critical thinking skills..

Posted March 13, 2020 | Reviewed by Ekua Hagan

• Find a Child Therapist

I recently received an email from an educator friend, asking me to briefly describe the skills necessary for critical thinking. They were happy to fill in the blanks themselves from outside reading but wanted to know what specific skills they should focus on teaching their students. I took this as a good opportunity to dedicate a post here to such discussion, in order to provide my friend and any other interested parties with an overview.

To understand critical thinking skills and how they factor into critical thinking, one first needs a definition of the latter. Critical thinking (CT) is a metacognitive process, consisting of a number of skills and dispositions, that when used through self-regulatory reflective judgment, increases the chances of producing a logical conclusion to an argument or solution to a problem (Dwyer, 2017; Dwyer, Hogan & Stewart, 2014). On the surface, this definition clarifies two issues. First, critical thinking is metacognitive—simply, it requires the individual to think about thinking; second, its main components are reflective judgment, dispositions, and skills.

Below the surface, this description requires clarification; hence the impetus for this entry—what is meant by reflective judgment, disposition towards CT, and CT skills? Reflective judgment (i.e. an individuals' understanding of the nature, limits, and certainty of knowing and how this can affect their judgments [King & Kitchener, 1994]) and disposition towards CT (i.e. an inclination, tendency or willingness to perform a given thinking skill [Dwyer, 2017; Facione, Facione & Giancarlo, 1997; Ku, 2009; Norris, 1992; Siegel, 1999; Valenzuela, Nieto & Saiz, 2011]) have both already been covered in my posts; so, consistent with the aim of this piece, let’s discuss CT skills.

CT skills allow individuals to transcend lower-order, memorization-based learning strategies to gain a more complex understanding of the information or problems they encounter (Halpern, 2014). Though debate is ongoing over the definition of CT, one list stands out as a reasonable consensus conceptualization of CT skills. In 1988, a committee of 46 experts in the field of CT gathered to discuss CT conceptualisations, resulting in the Delphi Report; within which was overwhelmingly agreement (i.e. 95% consensus) that analysis , evaluation and inference were the core skills necessary for CT (Facione, 1990). Indeed, over 30 years later, these three CT skills remain the most commonly cited.

1. Analysis

Analysis is a core CT skill used to identify and examine the structure of an argument, the propositions within an argument and the role they play (e.g. the main conclusion, the premises and reasons provided to support the conclusion, objections to the conclusion and inferential relationships among propositions), as well as the sources of the propositions (e.g. personal experience, common belief, and research).

When it comes to analysing the basis for a standpoint, the structure of the argument can be extracted for subsequent evaluation (e.g. from dialogue and text). This can be accomplished through looking for propositions that either support or refute the central claim or other reasons and objections. Through analysis, the argument’s hierarchical structure begins to appear. Notably, argument mapping can aid the visual representation of this hierarchical structure and is supported by research as having positive effects on critical thinking (Butchart et al., 2009; Dwyer, 2011; Dwyer, Hogan & Stewart, 2012; van Gelder, Bisset & Cumming, 2004).

2. Evaluation

Evaluation is a core CT skill that is used in the assessment of propositions and claims (identified through the previous analysis ) with respect to their credibility; relevance; balance, bias (and potential omissions); as well as the logical strength amongst propositions (i.e. the strength of the inferential relationships). Such assessment allows for informed judgment regarding the overall strength or weakness of an argument (Dwyer, 2017; Facione, 1990). If an argument (or its propositions) is not credible, relevant, logical, and unbiased, you should consider excluding it or discussing its weaknesses as an objection.

Evaluating the credibility of claims and arguments involves progressing beyond merely identifying the source of propositions in an argument, to actually examining the "trustworthiness" of those identified sources (e.g. personal experiences, common beliefs/opinions, expert/authority opinion and scientific evidence). This is particularly important because some sources are more credible than others. Evaluation also implies deep consideration of the relevance of claims within an argument, which is accomplished by assessing the contextual relevance of claims and premises—that is, the pertinence or applicability of one proposition to another.

With respect to balance, bias (and potential omissions), it's important to consider the "slant" of an argument—if it seems imbalanced in favour of one line of thinking, then it’s quite possible that the argument has omitted key, opposing points that should also be considered. Imbalance may also imply some level of bias in the argument—another factor that should also be assessed.

However, just because an argument is balanced does not mean that it isn’t biased. It may very well be the case that the "opposing views" presented have been "cherry-picked" because they are easily disputed (akin to building a strawman ); thus, making supporting reasons appear stronger than they may actually be—and this is just one example of how a balanced argument may, in fact, be biased. The take-home message regarding balance, bias, and potential omissions should be that, in any argument, you should construct an understanding of the author or speaker’s motivations and consider how these might influence the structure and contents of the argument.

Finally, evaluating the logical strength of an argument is accomplished through monitoring both the logical relationships amongst propositions and the claims they infer. Assessment of logical strength can actually be aided through subsequent inference, as a means of double-checking the logical strength. For example, this can be checked by asking whether or not a particular proposition can actually be inferred based on the propositions that precede it. A useful means of developing this sub-skill is through practicing syllogistic reasoning .

3. Inference

Similar to other educational concepts like synthesis (e.g., see Bloom et al., 1956; Dwyer, 2011; 2017), the final core CT skill, inference , involves the “gathering” of credible, relevant and logical evidence based on the previous analysis and evaluation, for the purpose of drawing a reasonable conclusion (Dwyer, 2017; Facione, 1990). Drawing a conclusion always implies some act of synthesis (i.e. the ability to put parts of information together to form a new whole; see Dwyer, 2011). However, inference is a unique form of synthesis in that it involves the formulation of a set of conclusions derived from a series of arguments or a body of evidence. This inference may imply accepting a conclusion pointed to by an author in light of the evidence they present, or "conjecturing an alternative," equally logical, conclusion or argument based on the available evidence (Facione, 1990). The ability to infer a conclusion in this manner can be completed through formal logic strategies, informal logic strategies (or both) in order to derive intermediate conclusions, as well as central claims.

Another important aspect of inference involves the querying of available evidence, for example, by recognising the need for additional information, gathering it and judging the plausibility of utilising such information for the purpose of drawing a conclusion. Notably, in the context of querying evidence and conjecturing alternative conclusions, inference overlaps with evaluation to a certain degree in that both skills are used to judge the relevance and acceptability of a claim or argument. Furthermore, after inferring a conclusion, the resulting argument should be re-evaluated to ensure that it is reasonable to draw the conclusion that was derived.

Overall, the application of critical thinking skills is a process—one must analyse, evaluate and then infer; and this process can be repeated to ensure that a reasonable conclusion has been drawn. In an effort to simplify the description of this process, for the past few years, I’ve used the analogy of picking apples for baking . We begin by picking apples from a tree. Consider the tree as an analogy, in its own right, for an argument, which is often hierarchically structured like a tree-diagram. By picking apples, I mean identifying propositions and the role they play (i.e. analysis). Once we pick an apple, we evaluate it—we make sure it isn’t rotten (i.e. lacks credibility, is biased) and is suitable for baking (i.e. relevant and logically strong). Finally, we infer— we gather the apples in a basket and bring them home and group them together based on some rationale for construction— maybe four for a pie, three for a crumble and another four for a tart. By the end of the process, we have baked some apple-based goods, or developed a conclusion, solution or decision through critical thinking.

Of course, there is more to critical thinking than the application of skills—a critical thinker must also have the disposition to think critically and engage reflective judgment. However, without the appropriate skills—analysis, evaluation, and inference, it is not likely that CT will be applied. For example, though one might be willing to use CT skills and engage reflective judgment, they may not know how to do so. Conversely, though one might be aware of which CT skills to use in a given context and may have the capacity to perform well when using these skills, they may not be disposed to use them (Valenzuela, Nieto & Saiz, 2011). Though the core CT skills of analysis, evaluation, and inference are not the only important aspects of CT, they are essential for its application.

Critical Thinking and Evaluating Information

Critical thinking.

As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important of these skills is critical thinking because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It is a “domain-general” thinking skill, not one that is specific to a particular subject area.

What Is Critical Thinking?

Critical thinking  is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions rather than simply memorizing facts or blindly accepting what you hear or read.

Imagine, for example, that you’re reading a history textbook. You wonder who wrote it and why, because you detect certain biases in the writing. You find that the author has a limited scope of research focused only on a particular group within a population. In this case, your critical thinking reveals that there are “other sides to the story.”

Who are critical thinkers, and what characteristics do they have in common? Critical thinkers are usually curious and reflective people. They like to explore and probe new areas and seek knowledge, clarification, and new solutions. They ask pertinent questions, evaluate statements and arguments, and they distinguish between facts and opinion. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit lack of knowledge or understanding when needed. They are open to changing their mind. Perhaps most of all, they actively enjoy learning, and seeking new knowledge is a lifelong pursuit. This may well be you!

No matter where you are on the road to being a critical thinker, you can always more fully develop and finely tune your skills. Doing so will help you develop more balanced arguments, express yourself clearly, read critically, and glean important information efficiently. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching. With critical thinking, you become a clearer thinker and problem solver.

Critical Thinking and Logic

Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly-held belief or a new idea. With critical thinking, anything and everything is subject to question and examination for the purpose of logically constructing reasoned perspectives.

What Is Logic?

The word  logic  comes from the Ancient Greek  logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and reasoning and strives to distinguish between good and bad reasoning, or between truth and falsehood. Using logic, you can evaluate the ideas and claims of others, make good decisions, and form sound beliefs about the world. [1]

Questions of Logic in Critical Thinking

Let’s use a simple example of applying logic to a critical-thinking situation. In this hypothetical scenario, a man has a Ph.D. in political science, and he works as a professor at a local college. His wife works at the college, too. They have three young children in the local school system, and their family is well known in the community. The man is now running for political office. Are his credentials and experience sufficient for entering public office? Will he be effective in the political office? Some voters might believe that his personal life and current job, on the surface, suggest he will do well in the position, and they will vote for him. In truth, the characteristics described don’t guarantee that the man will do a good job. The information is somewhat irrelevant. What else might you want to know? How about whether the man had already held a political office and done a good job? In this case, we want to think critically about how much information is adequate in order to make a decision based on  logic  instead of  assumptions.

The following questions, presented in Figure 1, below, are ones you may apply to formulating a logical, reasoned perspective in the above scenario or any other situation:

• What’s happening?  Gather the basic information and begin to think of questions.
• Why is it important?  Ask yourself why it’s significant and whether or not you agree.
• What don’t I see?  Is there anything important missing?
• How do I know?  Ask yourself where the information came from and how it was constructed.
• Who is saying it?  What’s the position of the speaker and what is influencing them?
• What else?   What if?  What other ideas exist and are there other possibilities?

Problem-Solving with Critical Thinking

For most people, a typical day is filled with critical thinking and problem-solving challenges. In fact, critical thinking and problem-solving go hand-in-hand. They both refer to using knowledge, facts, and data to solve problems effectively. But with problem-solving, you are specifically identifying, selecting, and defending your solution. Below are some examples of using critical thinking to problem-solve:

• Your roommate was upset and said some unkind words to you, which put a crimp in the relationship. You try to see through the angry behaviors to determine how you might best support the roommate and help bring the relationship back to a comfortable spot.
• Your campus club has been languishing due to lack of participation and funds. The new club president, though, is a marketing major and has identified some strategies to interest students in joining and supporting the club. Implementation is forthcoming.
• Your final art class project challenges you to conceptualize form in new ways. On the last day of class when students present their projects, you describe the techniques you used to fulfill the assignment. You explain why and how you selected that approach.
• Your math teacher sees that the class is not quite grasping a concept. She uses clever questioning to dispel anxiety and guide you to a new understanding of the concept.
• You have a job interview for a position that you feel you are only partially qualified for, although you really want the job and you are excited about the prospects. You analyze how you will explain your skills and experiences in a way to show that you are a good match for the prospective employer.
• You are doing well in college, and most of your college and living expenses are covered. But there are some gaps between what you want and what you feel you can afford. You analyze your income, savings, and budget to better calculate what you will need to stay in college and maintain your desired level of spending.

Problem-Solving Action Checklist

Problem-solving can be an efficient and rewarding process, especially if you are organized and mindful of critical steps and strategies. Remember to assume the attributes of a good critical thinker: if you are curious, reflective, knowledge-seeking, open to change, probing, organized, and ethical, your challenge or problem will be less of a hurdle, and you’ll be in a good position to find intelligent solutions. The steps outlined in this checklist will help you adhere to these qualities in your approach to any problem:

Critical and Creative Thinking

Critical and creative thinking (described in more detail in Chapter 6: Theories of Learning) complement each other when it comes to problem-solving. The following words, by Dr. Andrew Robert Baker, are excerpted from his “Thinking Critically and Creatively” essay. Dr. Baker illuminates some of the many ways that college students will be exposed to critical and creative thinking and how it can enrich their learning experiences.

THINKING CRITICALLY AND CREATIVELY Critical thinking skills are perhaps the most fundamental skills involved in making judgments and solving problems. You use them every day, and you can continue improving them. The ability to think critically about a matter—to analyze a question, situation, or problem down to its most basic parts—is what helps us evaluate the accuracy and truthfulness of statements, claims, and information we read and hear. It is the sharp knife that, when honed, separates fact from fiction, honesty from lies, and the accurate from the misleading. We all use this skill to one degree or another almost every day. For example, we use critical thinking every day as we consider the latest consumer products and why one particular product is the best among its peers. Is it a quality product because a celebrity endorses it? Because a lot of other people may have used it? Because it is made by one company versus another? Or perhaps because it is made in one country or another? These are questions representative of critical thinking. The academic setting demands more of us in terms of critical thinking than everyday life. It demands that we evaluate information and analyze myriad issues. It is the environment where our critical thinking skills can be the difference between success and failure. In this environment we must consider information in an analytical, critical manner. We must ask questions—What is the source of this information? Is this source an expert one and what makes it so? Are there multiple perspectives to consider on an issue? Do multiple sources agree or disagree on an issue? Does quality research substantiate information or opinion? Do I have any personal biases that may affect my consideration of this information? It is only through purposeful, frequent, intentional questioning such as this that we can sharpen our critical thinking skills and improve as students, learners and researchers. While critical thinking analyzes information and roots out the true nature and facets of problems, it is creative thinking that drives progress forward when it comes to solving these problems. Exceptional creative thinkers are people that invent new solutions to existing problems that do not rely on past or current solutions. They are the ones who invent solution C when everyone else is still arguing between A and B. Creative thinking skills involve using strategies to clear the mind so that our thoughts and ideas can transcend the current limitations of a problem and allow us to see beyond barriers that prevent new solutions from being found. Brainstorming is the simplest example of intentional creative thinking that most people have tried at least once. With the quick generation of many ideas at once, we can block-out our brain’s natural tendency to limit our solution-generating abilities so we can access and combine many possible solutions/thoughts and invent new ones. It is sort of like sprinting through a race’s finish line only to find there is new track on the other side and we can keep going, if we choose. As with critical thinking, higher education both demands creative thinking from us and is the perfect place to practice and develop the skill. Everything from word problems in a math class, to opinion or persuasive speeches and papers, call upon our creative thinking skills to generate new solutions and perspectives in response to our professor’s demands. Creative thinking skills ask questions such as—What if? Why not? What else is out there? Can I combine perspectives/solutions? What is something no one else has brought-up? What is being forgotten/ignored? What about ______? It is the opening of doors and options that follows problem-identification. Consider an assignment that required you to compare two different authors on the topic of education and select and defend one as better. Now add to this scenario that your professor clearly prefers one author over the other. While critical thinking can get you as far as identifying the similarities and differences between these authors and evaluating their merits, it is creative thinking that you must use if you wish to challenge your professor’s opinion and invent new perspectives on the authors that have not previously been considered. So, what can we do to develop our critical and creative thinking skills? Although many students may dislike it, group work is an excellent way to develop our thinking skills. Many times I have heard from students their disdain for working in groups based on scheduling, varied levels of commitment to the group or project, and personality conflicts too, of course. True—it’s not always easy, but that is why it is so effective. When we work collaboratively on a project or problem we bring many brains to bear on a subject. These different brains will naturally develop varied ways of solving or explaining problems and examining information. To the observant individual we see that this places us in a constant state of back and forth critical/creative thinking modes. For example, in group work we are simultaneously analyzing information and generating solutions on our own, while challenging other’s analyses/ideas and responding to challenges to our own analyses/ideas. This is part of why students tend to avoid group work—it challenges us as thinkers and forces us to analyze others while defending ourselves, which is not something we are used to or comfortable with as most of our educational experiences involve solo work. Your professors know this—that’s why we assign it—to help you grow as students, learners, and thinkers! —Dr. Andrew Robert Baker,  Foundations of Academic Success: Words of Wisdom

Evaluating Information with Critical Thinking

Evaluating information can be one of the most complex tasks you will be faced with in college. But if you utilize the following four strategies, you will be well on your way to success:

• Read for understanding
• Examine arguments
• Clarify thinking
• Cultivate “habits of mind”

Read for Understanding

When you read, take notes or mark the text to track your thinking about what you are reading. As you make connections and ask questions in response to what you read,  you monitor your comprehension and enhance your long-term understanding of the material. You will want to mark important arguments and key facts. Indicate where you agree and disagree or have further questions. You don’t necessarily need to read every word, but make sure you understand the concepts or the intentions behind what is written. See the chapter on  Active Reading Strategies  for additional tips.

Examine Arguments

When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and examine the hard facts. You can use the spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the “hot” end of an argument—feelings, beliefs, cultural influences, and societal influences—and the “cold” end of an argument—scientific influences. The most compelling arguments balance elements from both ends of the spectrum. The following video explains this strategy in further detail:

Clarify Thinking

When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this well is mainly a process of asking and answering probing questions, such as the logic questions discussed earlier. Design your questions to fit your needs, but be sure to cover adequate ground. What is the purpose? What question are we trying to answer? What point of view is being expressed? What assumptions are we or others making? What are the facts and data we know, and how do we know them? What are the concepts we’re working with? What are the conclusions, and do they make sense? What are the implications?

Cultivate “Habits of Mind”

“Habits of mind” are the personal commitments, values, and standards you have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence, being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always, especially, questioning your own conclusions—in other words, developing an intellectual work ethic. Try to work these qualities into your daily life.

In 2010, a textbook being used in fourth-grade classrooms in Virginia became big news for all the wrong reasons. The book,  Our Virginia  by Joy Masoff, had caught the attention of a parent who was helping her child do her homework, according to  an article in  The Washington Post . Carol Sheriff was a historian for the College of William and Mary and as she worked with her daughter, she began to notice some glaring historical errors, not the least of which was a passage which described how thousands of African Americans fought for the South during the Civil War.

Further investigation into the book revealed that, although the author had written textbooks on a variety of subjects, she was not a trained historian. The research she had done to write  Our Virginia,  and in particular the information she included about Black Confederate soldiers, was done through the Internet and included sources created by groups like the Sons of Confederate Veterans, an organization which promotes views of history that de-emphasize the role of slavery in the Civil War.

How did a book with errors like these come to be used as part of the curriculum and who was at fault? Was it Masoff for using untrustworthy sources for her research? Was it the editors who allowed the book to be published with these errors intact? Was it the school board for approving the book without more closely reviewing its accuracy?

There are a number of issues at play in the case of  Our Virginia , but there’s no question that evaluating sources is an important part of the research process and doesn’t just apply to Internet sources. Using inaccurate, irrelevant, or poorly researched sources can affect the quality of your own work. Being able to understand and apply the concepts that follow is crucial to becoming a more savvy user and creator of information.

When you begin evaluating sources, what should you consider? The  CRAAP test  is a series of common evaluative elements you can use to evaluate the  C urrency,  R elevance,  A uthority,  A ccuracy, and  P urpose of your sources. The CRAAP test was developed by librarians at California State University at Chico and it gives you a good, overall set of elements to look for when evaluating a resource. Let’s consider what each of these evaluative elements means. You can visit the ACC Library’s Web page for a tutorial on  Evaluating Information  using the CRAAP test.

One of the most important and interesting steps to take as you begin researching a subject is selecting the resources that will help you build your thesis and support your assertions. Certain topics require you to pay special attention to how current your resource is—because they are time sensitive, because they have evolved so much over the years, or because new research comes out on the topic so frequently. When evaluating the currency of an article, consider the following:

• When was the item written, and how frequently does the publication come out?
• Is there evidence of newly added or updated information in the item?
• If the information is dated, is it still suitable for your topic?
• How frequently does information change about your topic?

Understanding what resources are most applicable to your subject and why they are applicable can help you focus and refine your thesis. Many topics are broad and searching for information on them produces a wide range of resources. Narrowing your topic and focusing on resources specific to your needs can help reduce the piles of information and help you focus in on what is truly important to read and reference. When determining relevance consider the following:

• Does the item contain information relevant to your argument or thesis?
• Read the article’s introduction, thesis, and conclusion.
• Scan main headings and identify article keywords.
• For book resources, start with the index or table of contents—how wide a scope does the item have? Will you use part or all of this resource?
• Does the information presented support or refute your ideas?
• If the information refutes your ideas, how will this change your argument?
• Does the material provide you with current information?
• What is the material’s intended audience?

Understanding more about your information’s source helps you determine when, how, and where to use that information. Is your author an expert on the subject? Do they have some personal stake in the argument they are making? What is the author or information producer’s background? When determining the authority of your source, consider the following:

• What are the author’s credentials?
• What is the author’s level of education, experience, and/or occupation?
• What qualifies the author to write about this topic?
• What affiliations does the author have? Could these affiliations affect their position?
• What organization or body published the information? Is it authoritative? Does it have an explicit position or bias?

Determining where information comes from, if the evidence supports the information, and if the information has been reviewed or refereed can help you decide how and whether to use a source. When determining the accuracy of a source, consider the following:

• Is the source well-documented? Does it include footnotes, citations, or a bibliography?
• Is information in the source presented as fact, opinion, or propaganda? Are biases clear?
• Can you verify information from the references cited in the source?
• Is the information written clearly and free of typographical and grammatical mistakes? Does the source look to be edited before publication? A clean, well-presented paper does not always indicate accuracy, but usually at least means more eyes have been on the information.

Knowing why the information was created is a key to evaluation. Understanding the reason or purpose of the information, if the information has clear intentions, or if the information is fact, opinion, or propaganda will help you decide how and why to use information:

• Is the author’s purpose to inform, sell, persuade, or entertain?
• Does the source have an obvious bias or prejudice?
• Is the article presented from multiple points of view?
• Does the author omit important facts or data that might disprove their argument?
• Is the author’s language informal, joking, emotional, or impassioned?
• Is the information clearly supported by evidence?

When you feel overwhelmed by the information you are finding, the CRAAP test can help you determine which information is the most useful to your research topic. How you respond to what you find out using the CRAAP test will depend on your topic. Maybe you want to use two overtly biased resources to inform an overview of typical arguments in a particular field. Perhaps your topic is historical and currency means the past hundred years rather than the past one or two years. Use the CRAAP test, be knowledgeable about your topic, and you will be on your way to evaluating information efficiently and well!

Developing Yourself As a Critical Thinker

Critical thinking is a fundamental skill for college students, but it should also be a lifelong pursuit. Below are additional strategies to develop yourself as a critical thinker in college and in everyday life:

• Reflect and practice : Always reflect on what you’ve learned. Is it true all the time? How did you arrive at your conclusions?
• Use wasted time : It’s certainly important to make time for relaxing, but if you find you are indulging in too much of a good thing, think about using your time more constructively. Determine when you do your best thinking and try to learn something new during that part of the day.
• Redefine the way you see things : It can be very uninteresting to always think the same way. Challenge yourself to see familiar things in new ways. Put yourself in someone else’s shoes and consider things from a different angle or perspective.  If you’re trying to solve a problem, list all your concerns: what you need in order to solve it, who can help, what some possible barriers might be, etc. It’s often possible to reframe a problem as an opportunity. Try to find a solution where there seems to be none.
• Analyze the influences on your thinking and in your life : Why do you think or feel the way you do? Analyze your influences. Think about who in your life influences you. Do you feel or react a certain way because of social convention, or because you believe it is what is expected of you? Try to break out of any molds that may be constricting you.
• Express yourself : Critical thinking also involves being able to express yourself clearly. Most important in expressing yourself clearly is stating one point at a time. You might be inclined to argue every thought, but you might have greater impact if you focus just on your main arguments. This will help others to follow your thinking clearly. For more abstract ideas, assume that your audience may not understand. Provide examples, analogies, or metaphors where you can.
• Enhance your wellness : It’s easier to think critically when you take care of your mental and physical health. Try taking activity breaks throughout the day to reach 30 to 60 minutes of physical activity each day. Scheduling physical activity into your day can help lower stress and increase mental alertness. Also,  do your most difficult work when you have the most energy . Think about the time of day you are most effective and have the most energy. Plan to do your most difficult work during these times. And be sure to  reach out for help i f you feel you need assistance with your mental or physical health (see  Maintaining Your Mental and Physical Health  for more information).

44 Critical Thinking Skills

Learning objectives.

By the end of this section, you will be able to:

• Describe the role that logic plays in critical thinking
• Explain how critical thinking skills can be used to problem-solve
• Describe how critical thinking skills can be used to evaluate information
• Identify strategies for developing yourself as a critical thinker

Thinking comes naturally. You don’t have to make it happen—it just does. But you can make it happen in different ways. For example, you can think positively or negatively. You can think with “heart” and you can think with rational judgment. You can also think strategically and analytically, and mathematically and scientifically. These are a few of the multiple ways in which the mind can process thought.

What are some forms of thinking you use? When do you use them, and why?

As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important of these skills is critical thinking. Critical thinking is important because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It’s a “domain-general” thinking skill—not a thinking skill that’s reserved for a one subject alone or restricted to a particular subject area.

Great leaders have highly attuned critical thinking skills, and you can, too. In fact, you probably have a lot of these skills already. Of all your thinking skills, critical thinking may have the greatest value.

What Is Critical Thinking?

Critical thinking  is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like, “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions, rather than simply memorizing facts or blindly accepting what you hear or read.

Imagine, for example, that you’re reading a history textbook. You wonder who wrote it and why, because you detect certain biases in the writing. You find that the author has a limited scope of research focused only on a particular group within a population. In this case, your critical thinking reveals that there are “other sides to the story.”

Who are critical thinkers, and what characteristics do they have in common?

• Critical thinkers are usually curious and reflective people. They like to explore and probe new areas and seek knowledge, clarification, and new solutions. They ask pertinent questions, evaluate statements and arguments, and distinguish between facts and opinion. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit a lack of knowledge or understanding when needed. They are open to changing their mind. Perhaps most of all, they actively enjoy learning, and seeking new knowledge is a lifelong pursuit.

This may well be you!

No matter where you are on the road to being a critical thinker, you can always more fully develop and finely tune your skills. Doing so will help you develop more balanced arguments, express yourself clearly, read critically, and glean important information efficiently. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching. With critical thinking, you become a clearer thinker and problem solver.

Critical Thinking and Logic

Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly-held belief or a new idea. With critical thinking, anything and everything is subject to question and examination for the purpose of logically constructing reasoned perspectives.

What Is Logic, and Why Is It Important in Critical Thinking?

The word  logic  comes from the Ancient Greek  logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and reasoning and strives to distinguish between good and bad reasoning, or between truth and falsehood. Using logic, you can evaluate ideas or claims people make, make good decisions, and form sound beliefs about the world. [1]

Questions of Logic in Critical Thinking

Let’s use a simple example of applying logic to a critical-thinking situation. In this hypothetical scenario, a man has a PhD in political science, and he works as a professor at a local college. His wife works at the college, too. They have three young children in the local school system, and their family is well known in the community. The man is now running for political office. Are his credentials and experience sufficient for entering public office? Will he be effective in the political office? Some voters might believe that his personal life and current job, on the surface, suggest he will do well in the position, and they will vote for him. In truth, the characteristics described don’t guarantee that the man will do a good job. The information is somewhat irrelevant. What else might you want to know? How about whether the man had already held a political office and done a good job? In this case, we want to ask, How much information is adequate in order to make a decision based on logic instead of assumptions?

The following questions, presented in Figure 1, below, are ones you may apply to formulating a logical, reasoned perspective in the above scenario or any other situation:

• What’s happening?  Gather the basic information and begin to think of questions.
• Why is it important?  Ask yourself why it’s significant and whether or not you agree.
• What don’t I see?  Is there anything important missing?
• How do I know?  Ask yourself where the information came from and how it was constructed.
• Who is saying it?  What’s the position of the speaker and what is influencing them?

Problem-Solving

For most people, a typical day is filled with critical thinking and problem-solving challenges. In fact, critical thinking and problem-solving go hand-in-hand. They both refer to using knowledge, facts, and data to solve problems effectively. But with problem-solving, you are specifically identifying, selecting, and defending your solution. Below are some examples of using critical thinking to problem-solve:

• Your roommate was upset and said some unkind words to you, which put a crimp in the relationship. You try to see through the angry behaviors to determine how you might best support the roommate and help bring the relationship back to a comfortable spot.
• Your campus club has been languishing on account of a lack of participation and funds. The new club president, though, is a marketing major and has identified some strategies to interest students in joining and supporting the club. Implementation is forthcoming.
• Your final art class project challenges you to conceptualize form in new ways. On the last day of class when students present their projects, you describe the techniques you used to fulfill the assignment. You explain why and how you selected that approach.
• Your math teacher sees that the class is not quite grasping a concept. She uses clever questioning to dispel anxiety and guide you to new understanding of the concept.
• You have a job interview for a position that you feel you are only partially qualified for, although you really want the job and you are excited about the prospects. You analyze how you will explain your skills and experiences in a way to show that you are a good match for the prospective employer.
• You are doing well in college, and most of your college and living expenses are covered. But there are some gaps between what you want and what you feel you can afford. You analyze your income, savings, and budget to better calculate what you will need to stay in college and maintain your desired level of spending.

Evaluating Information

Evaluating information can be one of the most complex tasks you will be faced with in college. But if you utilize the following four strategies, you will be well on your way to success:

• Read for understanding by using text coding
• Examine arguments
• Clarify thinking
• Cultivate “habits of mind”

Examine Arguments

When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and examine the hard facts. You can use the  spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the “hot” end of an argument—feelings, beliefs, cultural influences, and societal influences—and the “cold” end of an argument—scientific influences.

Clarify Thinking

When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this well is mainly a process of asking and answering probing questions, such as the logic questions discussed earlier. Design your questions to fit your needs, but be sure to cover adequate ground. What is the purpose? What question are we trying to answer? What point of view is being expressed? What assumptions are we or others making? What are the facts and data we know, and how do we know them? What are the concepts we’re working with? What are the conclusions, and do they make sense? What are the implications?

Cultivate “Habits of Mind”

“Habits of mind” are the personal commitments, values, and standards you have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence, being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always, especially, questioning your own conclusions—in other words, developing an intellectual work ethic. Try to work these qualities into your daily life.

Developing Yourself as a Critical Thinker

Critical thinking is a desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and hatred for every kind of imposture. —Francis Bacon, philosopher

Critical thinking is a fundamental skill for college students, but it should also be a lifelong pursuit. Below are additional strategies to develop yourself as a critical thinker in college and in everyday life:

• Reflect and practice : Always reflect on what you’ve learned. Is it true all the time? How did you arrive at your conclusions?
• Use wasted time : It’s certainly important to make time for relaxing, but if you find you are indulging in too much of a good thing, think about using your time more constructively. Determine when you do your best thinking and try to learn something new during that part of the day.
• Redefine the way you see things : It can be very uninteresting to always think the same way. Challenge yourself to see familiar things in new ways. Put yourself in someone else’s shoes and consider things from a different angle or perspective.  If you’re trying to solve a problem, list all your concerns: what you need in order to solve it, who can help, what some possible barriers might be, etc. It’s often possible to reframe a problem as an opportunity. Try to find a solution where there seems to be none.
• Analyze the influences on your thinking and in your life : Why do you think or feel the way you do? Analyze your influences. Think about who in your life influences you. Do you feel or react a certain way because of social convention, or because you believe it is what is expected of you? Try to break out of any molds that may be constricting you.
• Express yourself : Critical thinking also involves being able to express yourself clearly. Most important in expressing yourself clearly is stating one point at a time. You might be inclined to argue every thought, but you might have greater impact if you focus just on your main arguments. This will help others to follow your thinking clearly. For more abstract ideas, assume that your audience may not understand. Provide examples, analogies, or metaphors where you can.
• Enhance your wellness : It’s easier to think critically when you take care of your mental and physical health.  Try taking 10-minute activity breaks to reach 30 to 60 minutes of physical activity each day . Try taking a break between classes and walk to the coffee shop that’s farthest away. Scheduling physical activity into your day can help lower stress and increase mental alertness. Also,  do your most difficult work when you have the most energy . Think about the time of day you are most effective and have the most energy. Plan to do your most difficult work during these times. And be sure to  reach out for help . If you feel you need assistance with your mental or physical health, talk to a counselor or visit a doctor.

Key Takeaways

Critical thinking is a skill that will help speakers further develop their arguments and position their speech in a strong manner.

• Critical thinking utilizes thought, plan, and action. Be sure to consider the research at-hand and develop an argument that is logical and connects to the audience.
• It is important to conduct an audience analysis to understand the ways in which your research and argument will resonate with the group you are delivering your information to; you can strengthen your argument by accurately positioning your argument and yourself in within a diverse audience.

Critical Thinking: What It Is and Why It Counts

2023 Update Peter A. Facione, Ph.D.

The late George Carlin worked “critical thinking” into one of his comedic monologue rants on the perils of trusting our lives and fortunes to the decision-making of people who were gullible, uninformed, and unreflective. Had he lived to experience the economic collapse of 2008 and 2009, he would have surely added more to his caustic but accurate assessments regarding how failing to anticipate the consequences of one’s decisions often leads to disastrous results not only for the decision maker, but for many other people as well.

After years of viewing higher education as more of a private good which benefits only the student, we are again beginning to appreciate higher education as being also a public good which benefits society. Is it not a wiser social policy to invest in the education of the future workforce, rather than to suffer the financial costs and endure the fiscal and social burdens associated with economic weakness, public health problems, crime, and avoidable poverty? Perhaps that realization, along with its obvious advantages for high level strategic decision making, is what led the Chairperson of the Joint Chiefs of Staff to comment on critical thinking in his commencement address to a graduating class of military officers.

Teach people to make good decisions and you have equipped them to improve their own futures and become contributing members of society, rather than burdens on society. Becoming educated and practicing good judgment does not absolutely guarantee a life of happiness, virtue, or economic success, but it surely offers a better chance at those things. And it is clearly better than enduring the consequences of making bad decisions and better than burdening friends, family, and all the rest of us with the unwanted and avoidable consequences of those poor choices.

Defining “Critical Thinking”

Yes, surely, we have all heard business executives, policy makers, civic leaders, and educators talking about critical thinking. At times we found ourselves wondering exactly what critical thinking was and why it is considered so useful and important. This essay takes a deeper look at these questions.

But rather than beginning with an abstract definition – as if critical thinking were about memorization, which is not the case – give this thought experiment a try: Imagine you were invited to a movie by a friend. But it is not a movie you want to see. So, your friend asks you why. You give your honest reason. The movie offends your sense of decency. Your friend asks you to clarify your reason by explaining what bothers you about the film. You reply that it is not the language used or the sexuality portrayed, but you find the violence in the film offensive.

Sure, that should be a good enough answer. But suppose your friend, perhaps being a bit philosophically inclined or simply curious or argumentative, pursues the matter further by asking you to define what you mean by “offensive violence.”

Take a minute and give it a try. How would you define “offensive violence” as it applies to movies? Can you write a characterization which captures what this commonly used concept contains? Take care, though, we would not want to make the definition so broad that all movie violence would be automatically “offensive.” And check to be sure your way of defining “offensive violence” fits with how the rest of the people who know and use English would understand the term. Otherwise, they will not be able to understand what you mean when you use that expression.

Did you produce a definition that works? How do you know?

What you just did with the expression “offensive violence” is very much the same as what had to be done with the expression “critical thinking.” At one level we all know what “critical thinking” means — it means good thinking, almost the opposite of illogical, irrational, thinking. But when we test our understanding further, we run into questions. For example, is critical thinking the same as creative thinking, are they different, or is one part of the other? How do critical thinking and native intelligence or scholastic aptitude relate? Does critical thinking focus on the subject matter or content that you know or on the process you use when you reason about that content?

It might not hurt at all if you formed some tentative preliminary ideas about the questions we just raised. We humans learn better when we stop frequently to reflect, rather than just plowing from the top of the page to the bottom without coming up for air.

Back to critical thinking – let us ask ourselves to generate possible examples of strong critical thinking? How about the adroit and clever questioning of Socrates or a good attorney or interviewer? Or, what about the clever investigative approaches used by police detectives and crime scene analysts? Would we not want to also include people working together to solve a problem as they consider and discuss their options? How about someone who is good at listening to all sides of a dispute, considering all the facts, and then deciding what is relevant and what is not, and then rendering a thoughtful judgment? And maybe too, someone who can summarize complex ideas clearly with fairness to all sides, or a person who can come up with the most coherent and justifiable explanation of what a passage of written material means? Or the person who can readily devise sensible alternatives to explore, but who does not become defensive about abandoning them if they do not work? And the person who can explain exactly how a particular conclusion was reached, or why certain criteria apply?

Or, considering the concept of critical thinking from the opposite direction, we might ask what the consequences of failing to use our critical thinking might be. Imagine for a moment what could happen when a person or a group of people decides important matters without pausing first to think things through.

Expert Opinion

An international group of experts was asked to try to form a consensus about the meaning of critical thinking. One of the first things they did was to ask themselves the question: Who are the best critical thinkers we know and what is it about them that leads us to consider them the best? So, who are the best critical thinkers you know? Why do you think they are strong critical thinkers? Can you draw from those examples a description that is more abstract? For example, consider effective trial lawyers, apart from how they conduct their personal lives or whether their client is guilty or innocent, just look at how the lawyers develop their cases in court. They use reasons to try to convince the judge and jury of their client’s claim of guilt or innocence. They offer evidence and evaluate the significance of the evidence presented by the opposition lawyers. They interpret testimony. They analyze and evaluate the arguments advanced by the other side.

Now, consider the example of a team of people trying to solve a problem. The team members, unlike the courtroom’s adversarial situation, try to collaborate. The members of an effective team do not compete against each other. They work together, like colleagues, for the common goal. Unless they solve the problem, none of them has won. When they find the way to solve the problem, they all have won. So, from analyzing just two examples we can generalize something especially important: critical thinking is thinking that has a purpose (proving a point, interpreting what something means, solving a problem), but critical thinking can be a collaborative, noncompetitive endeavor. And, by the way, even lawyers collaborate. They can work together on a common defense or a joint prosecution, and they can also cooperate with each other to get to the truth so that justice is done.

We will come to a more precise definition of critical thinking soon enough. But first, there is something else we can learn from paradigm examples. When were you thinking about “offensive violence” did you come up with any examples that were tough to classify? Borderline cases, as it were — an example that one person might consider offensive, but another might reasonably regard as non-offensive. Yes, well, so did we. This is going to happen with all abstract concepts. It happens with the concept of critical thinking as well. There are people of whom we would say, on certain occasions, this person is a good thinker, clear, logical, thoughtful, attentive to the facts, open to alternatives, but, wow, at other times, look out! When you get this person on such-and-such a topic, well it is all over then. You have pushed some kind of button, and the person does not want to hear what anybody else has to say. The person’s mind is made up ahead of time. New facts are pushed aside. No other point of view is tolerated.

Do you know any people that might fit that general description?

Now, formulate a list of cases — people that are clearly strong critical thinkers and clearly weak critical thinkers and some who are on the borderline. Considering all those cases, what is it about them that led you to decide which were which? Suggestion: What can the strong critical thinkers do (what mental abilities do they have), that the weak critical thinkers have trouble doing? What skills or approaches do the strong critical thinkers habitually seem to exhibit which the weak critical thinkers seem not to possess?

Core Critical Thinking Skills

Above we suggested you look for a list of mental skills and habits of mind, the experts, when faced with the same problem you are working on, refer to their lists as including cognitive skills and dispositions .

Quoting from the consensus statement of the national panel of experts: interpretation is “to comprehend and express the meaning or significance of a wide variety of experiences, situations, data, events, judgments, conventions, beliefs, rules, procedures, or criteria.” [1] Interpretation includes the sub-skills of categorization, decoding significance, and clarifying meaning. Can you think of examples of interpretation? How about recognizing a problem and describing it without bias? How about reading a person’s intentions in the expression on her face; distinguishing a main idea from subordinate ideas in a text; constructing a tentative categorization or way of organizing something you are studying; paraphrasing someone’s ideas in your own words; or, clarifying what a sign, chart or graph means? What about identifying an author’s purpose, theme, or point of view? How about what you did above when you clarified what “offensive violence” meant?

Again, from the experts: analysis is “to identify the intended and actual inferential relationships among statements, questions, concepts, descriptions, or other forms of representation intended to express belief, judgment, experiences, reasons, information, or opinions.” The experts include examining ideas, detecting arguments, and analyzing arguments as sub-skills of analysis. Again, can you come up with some examples of analysis? What about identifying the similarities and differences between two approaches to the solution of a given problem? What about picking out the main claim made in a newspaper editorial and tracing back the reasons the editor offers in support of that claim? Or, what about identifying unstated assumptions; constructing a way to represent a main conclusion and the reasons given to support or criticize it; sketching the relationship of sentences or paragraphs to each other and to the main purpose of the passage? What about graphically organizing this essay, in your own way, knowing that its purpose is to give a preliminary idea about what critical thinking means?

The experts define evaluation as meaning “to assess the credibility of statements or other representations which are accounts or descriptions of a person’s perception, experience, situation, judgment, belief, or opinion; and to assess the logical strength of the actual or intended inferential relationships among statements, descriptions, questions or other forms of representation.” Your examples? How about judging an author’s or speaker’s credibility, comparing the strengths and weaknesses of alternative interpretations, determining the credibility of a source of information, judging if two statements contradict each other, or judging if the evidence at hand supports the conclusion being drawn? Among the examples the experts propose are these: “recognizing the factors which make a person a credible witness regarding a given event or a credible authority with regard to a given topic,” “judging if an argument’s conclusion follows either with certainty or with a high level of confidence from its premises,” “judging the logical strength of arguments based on hypothetical situations,” “judging if a given argument is relevant or applicable or has implications for the situation at hand.”

Do the people you regard as strong critical thinkers have the three cognitive skills described so far? Are they good at interpretation, analysis, and evaluation? What about the next three? And your examples of weak critical thinkers, are they lacking in these cognitive skills? All, or just some?

To the experts, inference means “to identify and secure elements needed to draw reasonable conclusions; to form conjectures and hypotheses; to consider relevant information and to reason to the consequences flowing from data, statements, principles, evidence, judgments, beliefs, opinions, concepts, descriptions, questions, or other forms of representation.” As sub-skills of inference the experts list querying evidence, conjecturing alternatives, and drawing conclusions. Can you think of some examples of inference? You might suggest things like seeing the implications of the position someone is advocating. Or drawing out or constructing meaning from the elements in a reading. You may suggest predicting what will happen next based on what is known about the forces at work in a given situation. Or formulating a synthesis of related ideas into a coherent perspective. How about this: after judging that it would be useful to you to resolve a given uncertainty, developing a workable plan to gather that information? Or, when faced with a problem, developing a set of options for addressing it. What about conducting a controlled experiment scientifically and applying the proper statistical methods to attempt to confirm or disconfirm an empirical hypothesis?

Beyond being able to interpret, analyze, evaluate, and infer, strong critical thinkers can do two more things. They can explain what they think and how they arrived at that judgment. And they can apply their powers of critical thinking to themselves and improve on their previous opinions. These two skills are called “explanation” and “self-regulation.”

The experts define explanation as being able to present in a cogent and coherent way the results of one’s reasoning. This means to be able to give someone a full look at the big picture: both “to state and to justify that reasoning in terms of the evidential, conceptual, methodological, criteriological, and contextual considerations upon which one’s results were based; and to present one’s reasoning in the form of cogent arguments.” The sub-skills under explanation are describing methods and results, justifying procedures, proposing, and defending with good reasons one’s causal and conceptual explanations of events or points of view, and presenting full and well-reasoned, arguments in the context of seeking the best understandings possible. Your examples first, please… Here are some more: to construct a chart which organizes one’s findings, to write down for future reference your current thinking on some important and complex matter, to cite the standards and contextual factors used to judge the quality of an interpretation of a text, to state research results and describe the methods and criteria used to achieve those results, to appeal to established criteria as a way of showing the reasonableness of a given judgment, to design a graphic display which accurately represents the subordinate and super-ordinate relationship among concepts or ideas, to cite the evidence that led you to accept or reject an author’s position on an issue, to list the factors that were considered in assigning a final course grade.

Maybe the most remarkable cognitive skill of all, however, is this next one. This one is remarkable because it allows strong critical thinkers to improve their own thinking. In a sense this is critical thinking applied to itself. Because of that some people want to call this “meta-cognition,” meaning it raises thinking to another level. But “another level” really does not fully capture it, because at that next level up what self-regulation does is look back at all the dimensions of critical thinking and double check itself. Self-regulation is like a recursive function in mathematical terms, which means it can apply to everything, including itself. You can monitor and correct an interpretation you offered. You can examine and correct an inference you have drawn. You can review and reformulate one of your own explanations. You can even examine and correct your ability to examine and correct yourself! How? It is as simple as stepping back and saying to yourself, “How am I doing? Have I missed anything important? Let me double check before I go further.”

The experts define self-regulation to mean “self-consciously to monitor one’s cognitive activities, the elements used in those activities, and the results educed, particularly by applying skills in analysis, and evaluation to one’s own inferential judgments with a view toward questioning, confirming, validating, or correcting either one’s reasoning or one’s results.” The two sub-skills here are self-examination and self-correction. Examples? Easy — to examine your views on a controversial issue with sensitivity to the possible influences of your personal biases or self-interest, to check yourself when listening to a speaker in order to be sure you are understanding what the person is really saying without introducing your own ideas, to monitor how well you seem to be understanding or comprehending what you are reading or experiencing, to remind yourself to separate your personal opinions and assumptions from those of the author of a passage or text, to double check yourself by recalculating the figures, to vary your reading speed and method mindful of the type of material and your purpose for reading, to reconsider your interpretation or judgment in view of further analysis of the facts of the case, to revise your answers in view of the errors you discovered in your work, to change your conclusion in view of the realization that you had misjudged the importance of certain factors when coming to your earlier decision. [2]

The Delphi Research Method

The panel of experts we keep referring to included forty-six men and women from throughout the United States and Canada. They represented many different scholarly disciplines in the humanities, sciences, social sciences, and education. They participated in a research project that lasted two years and was conducted on behalf of the American Philosophical Association. Their work was published under the title Critical Thinking: A Statement of Expert Consensus for Purposes of Educational Assessment and Instruction . The executive summary is available from www.insightassessment.com

You might be wondering how such a large group of people could collaborate on this project over that long a period and at those distances and still come to a consensus. Good question. Remember we are talking the days before e-mail.

Not only did the group have to rely on snail mail during their two-year collaboration; they used a method of interaction, known as the Delphi Method, which was developed precisely to enable experts to think effectively about something over large spans of distance and time. In the Delphi Method a central investigator organizes the group and feeds them an initial question. [In this case it had to do with how college level critical thinking should be defined so that people teaching at that level would know which skills and dispositions to cultivate in their students.] The central investigator receives all responses, summarizes them, and transmits them back to all the panelists for reactions, replies, and additional questions.

Wait a minute! These are all well-known experts, so what do you do if people disagree? And what about the possible influence of a big-name person? Good points. First, the central investigator takes precautions to remove names so that the panelists are not told who said what. They know who is on the panel, of course. But that is as far as it goes. After that each experts’ argument must stand on its own merits. Second, an expert is only as good as the arguments she or he gives. So, the central investigator summarizes the arguments and lets the panelists decide if they accept them or not. When consensus appears to be at hand, the central investigator proposes this and asks if people agree. If not, then points of disagreement among the experts are registered. We want to share with you one important example of each of these. First, we will describe the expert consensus view of the dispositions which are vital to strong critical thinking. Then we will note a point of separation among the experts.

The Disposition Toward Critical Thinking

What kind of a person would be apt to use their critical thinking skills? The experts poetically describe such a person as having “a critical spirit.” Having a critical spirit does not mean that the person is always negative and hypercritical of everyone and everything.

The experts use the metaphorical phrase critical spirit in a positive sense. By it they mean “a probing inquisitiveness, a keenness of mind, a zealous dedication to reason, and a hunger or eagerness for reliable information. ”

Almost sounds like Supreme Court Justice Sandra Day O’Connor or Sherlock Holmes The kind of person being described here is the kind that always wants to ask “Why?” or “How?” or “What happens if?”. The one key difference, however, is that in fiction Sherlock always solves the mystery, while in the real world there is no guarantee. Critical thinking is about how you approach problems, questions, issues. It is the best way we know of to get to the truth. But! There still are no guarantees — no answers in the back of the book of real life. Does this characterization, that strong critical thinkers possess a “critical spirit, a probing inquisitiveness, a keenness of mind…” fit with your examples of people you would call strong critical thinkers?

But you might say, I know people who have skills but do not use them. We cannot call someone a strong critical thinker just because she or he has these cognitive skills, however important they might be, because what if they just do not bother to apply them?

One response is to say that it is hard to imagine an accomplished dancer who never dances. After working to develop those skills it seems such a shame to let them grow weak with lack of practice. But dancers get tired. And they surrender to the stiffness of age or the fear of injury. In the case of critical thinking skills, we might argue that not using them once you have them is hard to imagine. It’s hard to imagine a person deciding not to think.

Considered as a form of thoughtful judgment or reflective decision-making, in a very real sense critical thinking is pervasive . There is hardly a time or a place where it would not seem to be of potential value. As long as people have purposes in mind and wish to judge how to accomplish them, as long as people wonder what is true and what is not, what to believe and what to reject, strong critical thinking is going to be necessary.

And yet weird things happen, so it is probably true that some people might let their thinking skills grow dull. It is easier to imagine times when people are just too tired, too lax, or too frightened. But imagine it you can, Young Skywalker, so there must be more to critical thinking than just the list of cognitive skills. Human beings are more than thinking machines. And this brings us back to those all-important attitudes which the experts called “dispositions.”

The experts were persuaded that critical thinking is a pervasive and purposeful human phenomenon. The ideal critical thinker can be characterized not merely by her or his cognitive skills but also by how she or he approaches life and living in general. This is a bold claim. Critical thinking goes way beyond the classroom. In fact, many of the experts fear that some of the things people experience in school are harmful to the development and cultivation of strong critical thinking. Critical thinking came before schooling was ever invented; it lies at the very roots of civilization. It is a cornerstone in the journey humankind is taking from beastly savagery to global sensitivity. Consider what life would be like without the things on this list and we think you will understand.

The approaches to life and living which characterize critical thinking include:

* inquisitiveness regarding a wide range of issues,

* concern to become and remain well-informed,

* alertness to opportunities to use critical thinking,

* trust in the processes of reasoned inquiry,

* self-confidence in one’s own abilities to reason,

* open-mindedness regarding divergent world views,

* flexibility in considering alternatives and opinions

* understanding of the opinions of other people,

* fair-mindedness in appraising reasoning,

* honesty in facing one’s own biases, prejudices, stereotypes, or egocentric tendencies,

* prudence in suspending, making, or altering judgments,

* willingness to reconsider and revise views where honest reflection suggests that change is warranted.

What would someone be like who lacked those dispositions?

It might be someone who does not care about much of anything, is not interested in the facts, prefers not to think, mistrusts reasoning as a way of finding things out or solving problems, holds his or her own reasoning abilities in low esteem, is close-minded, inflexible, insensitive, cannot understand what others think, is unfair when it comes to judging the quality of arguments, denies his or her own biases, jumps to conclusions or delays too long in making judgments, and never is willing to reconsider an opinion. Not someone prudent people would want to ask to manage their investments!

The experts went beyond approaches to life and living in general to emphasize that strong critical thinkers can also be described in terms of how they approach specific issues, questions, or problems. The experts said you would find these sorts of characteristics:

* clarity in stating the question or concern,

* orderliness in working with complexity,

* diligence in seeking relevant information,

* reasonableness in selecting and applying criteria,

* care in focusing attention on the concern at hand,

* persistence though difficulties are encountered,

* precision to the degree permitted by the subject and the circumstances.

So, how would a weak critical thinker approach specific problems or issues? Obviously, by being muddle-headed about what he or she is doing, disorganized and overly simplistic, spotty about getting the facts, apt to apply unreasonable criteria, easily distracted, ready to give up at the least hint of difficulty, intent on a solution that is more detailed than is possible, or being satisfied with an overly generalized and uselessly vague response. Remind you of anyone you know?

Someone positively disposed toward using critical thinking would probably agree with statements like these:

“I hate talk shows where people shout their opinions but never give any reasons at all.”“Figuring out what people really mean by what they say is important to me.”

“I always do better in jobs where I’m expected to think things out for myself.”

“I hold off making decisions until I have thought through my options.”

“Rather than relying on someone else’s notes, I prefer to read the material myself.”

“I try to see the merit in another’s opinion, even if I reject it later.”

“Even if a problem is tougher than I expected, I will keep working on it.”

“Making intelligent decisions is more important than winning arguments.”

A person disposed to be averse or hostile toward using critical thinking would probably disagree with the statements above but be likely to agree with these:

“I prefer jobs where the supervisor says exactly what to do and exactly how to do it.”“No matter how complex the problem, you can bet there will be a simple solution.”

“I don’t waste time looking things up.”

“I hate when teachers discuss problems instead of just giving the answers.”

“If my belief is truly sincere, evidence to the contrary is irrelevant.”

“Selling an idea is like selling cars, you say whatever works.”

We used the expression “strong critical thinker” to contrast with the expression “weak critical thinker.” But you will find people who drop the adjective “strong” (or “good”) and just say that someone is a “critical thinker” or not. It is like saying that a soccer (European “football”) player is a “defender” or “not a defender”, instead of saying the player’s skills at playing defense are strong or weak. People use the word “defender” in place of the phrase “is good at playing defense.” Similarly, people use “critical thinker” in place of “is a strong critical thinker” or “has strong critical thinking skills.” This is not only a helpful conversational shortcut, it suggests that to many people “critical thinker” has a laudatory sense. The word can be used to praise someone at the same time that it identifies the person, as in “Look at that play. That’s what I call a defender!”

“If we were compelled to make a choice between these personal attributes and knowledge about the principles of logical reasoning together with some degree of technical skill in manipulating special logical processes, we should decide for the former.”

John Dewey, How We Think , 1909. Republished as How We Think: A Restatement of the Relation of Reflective Thinking to the Educational Process . D. C. Heath Publishing. Lexington, MA. 1933.

We said the experts did not come to full agreement on something. That thing has to do with the concept of a “strong critical thinker.” This time the emphasis is on the word “good” because of the crucial ambiguity it contains. A person can be good at critical thinking, meaning that the person can have the appropriate dispositions and be adept at the cognitive processes, while still not being a good (in the moral sense) critical thinker. For example, a person can be adept at developing arguments and then, unethically, use this skill to mislead and exploit a gullible person, perpetrate a fraud, or deliberately confuse and confound, and frustrate a project.

The experts were faced with an interesting problem. Some, a minority, would prefer to think that critical thinking, by its very nature, is inconsistent with the kinds of unethical and deliberately counterproductive examples given. They find it hard to imagine a person who was good at critical thinking not also being good in the broader personal and social sense. In other words, if a person were “really” a “strong critical thinker” in the procedural sense and if the person had all the appropriate dispositions, then the person simply would not do those kinds of exploitive and aggravating things.

What We All Need Most Right Now

The large majority, however, hold the opposite judgment.

The majority are firm in the view that strong critical thinking has nothing to do with any given set of political or religious tenets, ethical values, cultural mores, orthodoxies, or ideologies of any kind. Rather, the commitment one makes as a strong critical thinker is to always seek the truth with objectivity, integrity, and fair-mindedness. Most experts maintain that critical thinking conceived of as we have described it above, is, regrettably, consistent with abusing one’s knowledge, skills, or power. There have been people with superior thinking skills and strong habits of mind who, unfortunately, have used their talents for ruthless, horrific, and immoral purposes. Would that it was not so! Would that experience, knowledge, mental horsepower, and ethical virtues were all the same. But from the time of Socrates, if not thousands of years before that, humans have known that many of us have one or more of these without having the full set.

Any tool, any approach to situations, can go either way, ethically speaking, depending on the character, integrity, and principles of the persons who possess them. So, in the final analysis most experts maintained that we cannot say a person is not thinking critically simply because we disapprove ethically of what the person is doing. The majority concluded that, “what ‘critical thinking’ means, why it is of value, and the ethics of its use are best regarded as three distinct concerns.”

Perhaps this realization forms part of the basis for why people these days are demanding a broader range of learning outcomes from our schools and colleges. “Knowledge and skills,” the staples of the educational philosophy of the mid-twentieth century, are not sufficient. We must look to a broader set of outcomes including habits of mind and dispositions, such as civic engagement, concern for the common good, and social responsibility.

“Thinking” in Popular Culture

We have said so many good things about critical thinking that you might have the impression that “critical thinking” and “good thinking” mean the same thing. But that is not what the experts said. They see critical thinking as making up part of what we mean by good thinking, but not as being the only kind of good thinking. For example, they would have included creative thinking as part of good thinking.

Creative or innovative thinking is the kind of thinking that leads to new insights, novel approaches, fresh perspectives, whole new ways of understanding and conceiving of things. The products of creative thought include some obvious things like music, poetry, dance, dramatic literature, inventions, and technical innovations. But there are some not so obvious examples as well, such as ways of putting a question that expand the horizons of viable solutions, or ways of conceiving of relationships which challenge presuppositions and lead one to see the world in imaginative and different ways.

The experts working on the concept of critical thinking wisely left open the entire question of what the other forms good thinking might take. Creative thinking is only one example. There is a kind of purposive, kinetic thinking that instantly coordinates movement and intention as, for example, when an athlete dribbles a soccer ball down the field during a match. There is a kind of meditative thinking which may lead to a sense of inner peace or to profound insights about human existence. In contrast, there is a kind of hyper-alert, instinctive thinking needed by soldiers in battle. In the context of popular culture, one finds people proposing all kinds of thinking or this kind of intelligence or that kind of intelligence. Sometimes it is hard to sort out science from pseudo-science – the kernel of enduring truth from the latest cocktail party banter.

“Thinking” in Cognitive Science

Theories emerging from more scientific studies of human thinking and decision-making in recent years propose that thinking is more integrated and less dualistic than the notions in popular culture suggest. We should be cautious about proposals suggesting oversimplified ways of understanding how humans think. We should avoid harsh, rigid dichotomies such as “reason vs. emotion,” “intuitive vs. linear,” “creativity vs. criticality,” “right brained vs. left brained,” “as on Mars vs. as on Venus.”

There is often a kernel of wisdom in popular beliefs, and perhaps that gem this time is the realization that sometimes we decide things very quickly almost as spontaneous, intuitive, reactions to the situation at hand. Many accidents on the freeways of this nation are avoided precisely because drivers can see and react to dangerous situations so quickly. Many good decisions which feel intuitive are really the fruit of expertise. Decisions good drivers make in those moments of crisis, just like the decisions which practiced athletes make in the flow of a game or the decisions that a gifted teacher makes as she or he interacts with students, are borne of expertise, training, and practice.

Recent integrative models of human decision-making propose that the thinking processes of our species is not best described as a conflictive duality as in “intuitive vs. reflective” but rather an integrative functioning of two mutually supportive systems “intuitive and reflective.” These two systems of thinking are present in all of us and can act in parallel to process cognitively the matters over which we are deciding.

One system is more intuitive, reactive, quick and holistic. So as not to confuse things with the notions of thinking in popular culture, cognitive scientists often name this system, “System 1.” The other (yes, you can guess its name) is more deliberative, reflective, computational and rule governed. You are right, it is called “ System 2 .”

In System 1 thinking, one relies heavily on several heuristics (cognitive maneuvers), key situational characteristics, readily associated ideas, and vivid memories to arrive quickly and confidently at a judgment. System 1 thinking is particularly helpful in familiar situations when time is short and immediate action is required.

While System 1 is functioning, another powerful system is also at work, that is, unless we shut it down by abusing alcohol or drugs, or with fear or indifference. Called “ System 2 ,” this is our more reflective thinking system. It is useful for making judgments when you find yourself in unfamiliar situations and have more time to figure things out. It allows us to process abstract concepts, to deliberate, to plan, to consider options carefully, to review and revise our work in the light of relevant guidelines or standards or rules of procedure. While System 2 decisions are also influenced by the correct or incorrect application of heuristic maneuvers, this is the system which relies on well-articulated reasons and more fully developed evidence. It is reasoning based on what we have learned through careful analysis, evaluation, explanation, and self-correction. This is the system which values intellectual honesty, analytically anticipating what happens next, maturity of judgment, fair-mindedness, elimination of biases, and truth-seeking. This is the system which we rely on to carefully think trough complex, novel, high-stakes, and highly integrative problems. [3]

Educators urge us to improve our critical thinking skills and to reinforce our disposition to use those skills because that is perhaps the best way to develop and refine our System 2 reasoning.

Cognitive heuristics are thinking maneuvers which, at times, appear to be almost hardwired into our species. They influence both systems of thinking, the intuitive thinking of System 1 and the reflective reasoning of System 2. Five heuristics often seem to be operating more frequently in our System 1 reasoning are known as availability, affect, association, simulation, and similarity .

Availability , the coming to mind of a story or vivid memory of something that happened to you or to someone close to you, inclines a person to make inaccurate estimates of the likelihood of that thing’s happening again. People tell stories of things that happened to themselves or their friends all the time as a way of explaining their own decisions. The stories may not be scientifically representative, the events may be mistaken, misunderstood, or misinterpreted. But all that aside, the power of the story is to guide, often in a good way, the decision toward one choice rather than another.

The Affect heuristic operates when you have an immediate positive or a negative reaction to some idea, proposal, person, object, whatever. Sometimes called a “gut reaction” this affective response sets up an initial orientation in us, positive or negative, toward the object. It takes a lot of System 2 reasoning to overcome a powerful affective response to an idea, but it can be done. And at times it should be, because there is no guarantee that your gut reaction is always right.

The Association heuristic is operating when one word or idea reminds us of something else. For example, some people associate the word “cancer” with “death.” Some associate “sunshine” with “happiness.” These kinds of associational reasoning responses can be helpful at times, as for example if associating cancer with death leads you not to smoke and to go in for regular checkups. At other times the same association may influence a person to make an unwise decision, as for example if associating “cancer” with “death” were to lead you to be so fearful and pessimistic that you do not seek diagnosis and treatment of a worrisome cancer symptom until it was really too late to do anything.

The Simulation heuristic works when you are imagining how various scenarios will unfold. People often imagine how a conversation will go, or how they will be treated by someone else when they meet the person, or what their friends or boss or lover will say and do when they must address some difficult issue. These simulations, like movies in our heads, help us prepare and do a better job when the difficult moment arrives. But they can also lead us to have mistaken expectations. People may not respond as we imagined, things may go much differently. Our preparations may fail us because the ease of our simulation misled us into thinking that things would have to go as we had imagined them. And they did not.

The Similarity heuristic operates when we notice some way in which we are like someone else and infer that what happened to that person is therefore more likely to happen to us. The similarity heuristic functions much like an analogical argument or metaphorical model. The similarity we focus on might be fundamental and relevant, which would make the inference more warranted. For example, the boss fired your coworker for missing sales targets, and you draw the reasonable conclusion that if you miss your sales target, you will be fired too. Or the similarity that comes to mind might be superficial or not connected with the outcome, which would make the inference unwarranted. For example, you see a TV commercial showing trim-figured young people enjoying fattening fast foods and infer that because you are young too you can indulge your cravings for fast foods without gaining a lot of excess unsightly poundage.

Heuristics and biases often appearing to be somewhat more associated with System 2 thinking include: satisficing, risk/loss aversion, anchoring with adjustment, and the illusion of control.

CRITICAL THINKING SKILLS MAP ON TO LEADERSHIP DECISION MAKING

Successful professionals with leadership responsibilities, like those in business or the military, apply all their critical thinking skills to solve problems and to make sound decisions. At the risk of oversimplifying all the ways that our critical thinking intersects with problem solving and leadership decision making, here are some of the more obvious connecting points:

• Analyze the strategic environment, identify its elements and their relationships
• Interpret events and other elements in the strategic environment for signs of risk, opportunity, weakness, advantage
• Infer , given what is known with precision and accuracy within the strategic environment, the logical and most predictable consequences of various courses of action
• Infer , given the range of uncertainty and risk in the strategic environment, the full range of the possible and probable consequences of each possible course of action
• Evaluate anticipated results for positive and negative impacts
• Evaluate risks, opportunities, options, consequences
• Explain the rationale (evidence, methodology, criteria, theoretical assumptions, and context) for deciding on the integrated strategic objectives and for the planning and action parameters that compose the strategy
• Double Check Everything: At every step review one’s own thinking and make necessary corrections.

Satisficing occurs as we consider our alternatives. When we come to one which is good enough to fulfill our objectives, we often regard ourselves as having completed our deliberations. We satisficed. And why not? The choice is, after all, good enough. It may not be perfect, it may not be optimal, it may not even be the best among the options available. But it is good enough. Time to decide and move forward.

The running mate of satisficing is temporizing. Temporizing is deciding that the option which we have come to is “good enough for now.” We often move through life satisficing and temporizing. At times we look back on our situations and wonder why it is that we have settled for far less than we might have. If we had only studied harder, worked out a little more, taken better care of ourselves and our relationships, perhaps we would not be living as we are now. But, at the time each of the decisions along the way was “good enough for the time being.”

We are by nature a species that is averse to risk and loss . We often make decisions based on what we are too worried about losing, rather than based on what we might gain. This works out to be a rather serviceable approach in many circumstances. People do not want to lose control, they do not want to lose their freedom, they do not want to lose their lives, their families, their jobs, their possessions. High stakes gambling is best left to those who can afford to lose the money. Las Vegas did not build all those multi-million-dollar casino hotels because vacationers are winning all the time! And so, in real life, we take precautions. We avoid unnecessary risks. The odds may not be stacked against us, but the consequences of losing at times are so great that we would prefer to forego the possibilities of gain in order not to lose what we have. And yet, on occasion this can be a most unfortunate decision too. History has shown time and time again that businesses which avoid risks often are unable to compete successfully with those willing to move more boldly into new markets or into new product lines.

Any heuristic is only a maneuver, perhaps a shortcut or impulse to think or act in one way rather than another, but certainly not a failsafe rule. It may work out well much of the time to rely on the heuristic, but it will not work out for the best all the time.

For example, people with something to lose tend toward conservative choices politically as well as economically. Nothing wrong with that necessarily. Just an observation about the influence of Loss Aversion heuristic on actual decision making. We are more apt to endure the status quo, even as it slowly deteriorates, than we are to call for “radical” change. Regrettably, however, when the call for change comes, it often requires a far greater upheaval to make the necessary transformations, or, on occasion, the situation has deteriorated beyond the point of no return. In those situations, we find ourselves wondering why we waited so long before doing something.

The heuristic known as Anchoring with Adjustment is operative when we find ourselves making evaluative judgments. The natural thing for us to do is to locate or anchor our evaluation at some point along whatever scale we are using. For example, a professor says that the student’s paper is a C+. Then, as other information comes our way, we may adjust that judgment. The professor, for example, may decide that the paper is as good as some others that were given a B-, and so adjust the grade upward. The interesting thing about this heuristic is that we do not normally start over with a fresh evaluation. We have dropped anchor, and we may drag it upward or downward a bit, but we do not pull it off the bottom of the sea to relocate our evaluation. First impressions, as the saying goes, cannot be undone. The good thing about this heuristic is that it permits us to move on. We have done the evaluation; there are other papers to grade, other projects to do, other things in life that need attention. We could not endure long if we had to constantly reevaluate everything anew. The unfortunate thing about this heuristic is that we sometimes drop anchor in the wrong place; we have a tough time giving people a second chance at making a good first impression.

The heuristic known as Illusion of Control is evident in many situations. Many of us overestimate our abilities to control what will happen. We make plans for how we are going to do this or that, say this or that, manipulate the situation this way or that way, share or not share this information or that possibility, all the time thinking that somehow our petty plans will enable us to control what happens. We function as if others are dancing on the ends of the strings that we are pulling, when the influences our words or actions have on future events may be quite negligible. At times we do have some measure of control. For example, we may exercise, not smoke, and watch our diet to be more fit and healthy. We are careful not to drink if we are planning to drive so that we reduce the risks of being involved in a traffic accident. But at times we simply are mistaken about our ability to exercise full control over a situation. Sadly, we might become ill even if we do work hard to take care of ourselves. Or we may be involved in an accident even if we are sober. Our business may fail even if we work hard to make it a success. We may not do as well on an exam as we might hope even if we study hard.

Related to the Illusion of Control heuristic is the tendency to misconstrue our personal influence or responsibility for past events. This is called Hindsight Bias. We may overestimate the influence our actions have had on events when things go right, or we may underestimate our responsibility or culpability when things go wrong. We have all heard people bragging about how they did this and how they did that and, as a result, such and such wonderful things happened. We made these great plans and look at how well our business did financially. Which may be true when the economy is strong but not when the economy is failing. It is not clear how much of that success came from the planning and how much came from the general business environment. Or, we have all been in the room when it was time to own up for something that went wrong and thought to ourselves, hey, I may have had some part in this, but it was not entirely my fault. “It was not my fault the children were late for school! Hey, I was dressed and ready to go at the regular time.” As if seeing that the family was running late, I had no responsibility to take some initiative and help.

“Insanity is doing the same thing over and over again while expecting a different outcome.”

Albert Einstein

Research on our shared heuristic patterns of decision-making does not aim to evaluate these patterns as necessarily good or bad patterns of thinking. I fear that my wording of them may not have been as entirely neutral and descriptive as perhaps it should have been. In truth, reliance on heuristics can be an efficient way of deciding things, given how complicated our lives are. We cannot devote maximal cognitive resources to every single decision we make.

Those of us who study these heuristic thinking phenomena are simply trying to document how we humans do think. There are many useful purposes for doing this. For example, if we find that people repeatedly make a given kind of mistake when thinking about a commonly experienced problem, then we might find ways to intervene and to help ourselves not repeat that error repeatedly.

This research on the actual patterns of thinking used by individuals and by groups might prove particularly valuable to those who seek interventions which could improve how we make our own heath care decisions, how we make business decisions, how we lead teams of people to work more effectively in collaborative settings, and the like.

Popular culture offers one other myth about decision-making which is worth questioning. And that is the belief that when we make reflective decisions, we carefully weigh each of our options, giving due consideration to all of them in turn, before deciding which we will adopt. Although perhaps it should be, research on human decision-making shows that this simply is not what happens. [4] When seeking to explain how people decide on an option with such conviction that they stick to their decision over time and with such confidence that they act on that decision, the concept that what we do is build a Dominance Structure has been put forth.

In a nutshell this theory suggests that when we settle on a particular option which is good enough, we tend to elevate its merits and diminish its flaws relative to the other options. We raise it up in our minds until it becomes for us the dominant option. In this way, as our decision takes shape, we gain confidence in our choice and we feel justified in dismissing the other options, even though the objective distance between any of them and our dominant option may not be very great at all. But we become invested in our dominant option to the extent that we can put the other possibilities aside and act based on our choice. In fact, it comes to dominate the other options in our minds so much that we can sustain our decision to act over time, rather than going back to re-evaluate or reconsider constantly. Understanding the natural phenomenon of dominance structuring can help us appreciate why it can be so difficult for us to get others to change their minds, or why it seems that our reasons for our decisions are so much better than any of the objections which others might make to our decisions. This is not to say that we are right or wrong. Rather, this is only to observe that human beings are capable of unconsciously building up defenses around their choices which can result in the warranted or unwarranted confidence to act based on those choices.

Realizing the power of dominance structuring, one can only be more committed to the importance of education and critical thinking. We should do all that we can to inform ourselves fully and to reflect carefully on our choices before we make them, because we are, after all, human and we are as likely as the next person to believe that we are right and they are wrong once the dominance structure begins to be erected. Breaking through that to fix bad decisions, which is possible, can be much harder than getting things right in the first place.

There are more heuristics than only those mentioned above. There is more to learn about dominance structuring as it occurs in groups as well as in individuals, and how to mitigate the problems which may arise by prematurely settling on a “good enough” option, or about how to craft educational programs or interventions which help people be more effective in their System 1 and System 2 thinking. There is much to learn about human thinking and how to optimize it in individuals of different ages; how to optimize the thinking of groups of peers and groups where organizational hierarchies influence interpersonal dynamics. And, happily, there is a lot we know today about human thinking and decision-making that we did not know a few years ago.

Why critical thinking?

Let us start with you first. Why would critical thinking be of value to you to have the cognitive skills of interpretation, analysis, evaluation, inference, explanation, and self-regulation?

Apart from, or maybe in light of, what we said at the beginning of this essay about the utility of positive critical thinking and about the problems that failures of critical thinking contribute to, why would it be of value to you to learn to approach life and to approach specific concerns with the critical thinking dispositions listed above? Would you have greater success in your work? Would you get better grades?

The answer to the grades question, scientifically speaking, is very possibly Yes! A study of over 1100 college students shows that scores on a college level critical thinking skills test significantly correlated with college GPA. [5] It has also been shown that critical thinking skills can be learned, which suggests that as one learns them one’s GPA might well improve. In further support of this hypothesis is the significant correlation between critical thinking and reading comprehension. Improvements in one are paralleled by improvements in the other. Now if you can read better and think better, you probably will do better in your classes, learn more, and get higher grades. It is, to say the least, very plausible.

Learning, Critical Thinking, and Our Nation’s Future

“The future now belongs to societies that organize themselves for learning… nations that want high incomes and full employment must develop policies that emphasize the acquisition of knowledge and skills by everyone, not just a select few.”

Ray Marshall & Marc Tucker, Thinking For A Living: Education And The Wealth of Nations , Basic Books. New York. 1992.

But what a limited benefit — better grades. Who really cares in the long run? Two years after college, five years out, what does GPA really mean? These days a college level technical and professional program has a half-life of about four years, which means that the technical content is expanding so fast and changing so much that in about four years after graduation your professional training will be in serious need of renewal. So, if the only thing a college is good for is to get the entry level training and the credential needed for a particular job, then college would be a time-limited value.

The APA Delphi Report, Critical Thinking: A Statement of Expert Consensus for Purposes of Educational Assessment and Instruction 1990 ERIC Doc. NO.: ED 315423

Is that the whole story? A job is a good thing, but is that what a college education is all about? Just getting started in a job? Maybe some cannot see its further value, but many do. A main purpose, if not the main purpose, of the collegiate experience, at either the two-year or the four-year level, is to achieve what people have called a “liberal education.” Not liberal in the sense of a smattering of this and that for no particular purpose except to fulfill the unit requirement. But liberal in the sense of “liberating.” And who is being liberated? You! Liberated from a kind of slavery. But from whom?

From professors. From dependence on professors so that they no longer stand as infallible authorities delivering opinions beyond our capacity to challenge, question, and dissent. In fact, this is exactly what the professors want. They want their students to excel on their own, to go beyond what is currently known, to make their own contributions to knowledge and to society. [Being a professor is a curious job — the more effective you are as a teacher, less your students require your aid in learning.]

Liberal education is about learning to learn, which means learning to think for yourself on your own and in collaboration with others.

Liberal education leads us away from naive acceptance of authority, above self-defeating relativism, and beyond ambiguous contextualism. It culminates in principled reflective judgment. Learning critical thinking, cultivating the critical spirit, is not just a means to this end, it is part of the goal itself. People who are weak critical thinkers, who lack the dispositions and skills described, cannot be said to be liberally educated, regardless of the academic degrees they may hold.

Yes, there is much more to a liberal education than critical thinking. There is an understanding of the methods, principles, theories, and ways of achieving knowledge which are proper to the different intellectual realms. There is an encounter with the cultural, artistic, and spiritual dimensions of life. There is the evolution of one’s decision making to the level of principled integrity and concern for the common good and social justice. There is the realization of the ways all our lives are shaped by global as well as local political, social, psychological, economic, environmental, and physical forces. There is the growth that comes from the interaction with cultures, languages, ethnic groups, religions, nationalities, and social classes other than one’s own. There is the refinement of one’s humane sensibilities through reflection on the recurring questions of human existence, meaning, love, life, and death. There is the sensitivity, appreciation, and critical appraisal of all that is good and all that is bad in the human condition. As the mind awakens and matures, and the proper nurturing and educational nourishment is provided, these others central parts of a liberal education develop as well. Critical thinking plays an essential role in achieving these purposes.

Anything else? What about going beyond the individual to the community?

The experts say critical thinking is fundamental to, if not essential for, “a rational and democratic society.” What might the experts mean by this?

Well, how wise would democracy be if people abandoned critical thinking? Imagine an electorate that did not care for the facts. An electorate that did not wish to consider the pros and cons of the issues. Or, worse, had neither the education nor the brain power to do so. Imagine your life and the lives of your friends and family placed in the hands of juries and judges who let their political allegiance, biases and stereotypes govern their decisions, who do not attend to the evidence, who are not interested in reasoned inquiry, who do not know how to draw an inference or evaluate one. Without critical thinking, people could easily be exploited not only politically but economically.

The impact of abandoning critical thinking would not be confined to the micro-economics of the household checking account. Suppose the people involved in international commerce were lacking in critical thinking skills, they would be unable to analyze and interpret the market trends, evaluate the implications of interest fluctuations, or explain the potential impact of those factors which influence large scale production and distribution of goods and materials. Suppose these people were unable to draw the proper inferences from the economic facts, or unable to evaluate the claims made by the unscrupulous and misinformed. In such a situation, serious economic mistakes would be made. Whole sectors of the economy would become unpredictable and large-scale economic disaster would become extremely likely. So, given a society that does not value and cultivate critical thinking, we might reasonably expect that in time the judicial system and the economic system would collapse. And, in such a society, one that does not liberate its citizens by teaching them to think critically for themselves, it would be madness to advocate democratic forms of government.

Is it any wonder that business and civic leaders are maybe even more interested in critical thinking than educators? Critical thinking employed by an informed citizenry is a necessary condition for the success of democratic institutions and for competitive free-market economic enterprise. These values are so important that it is in the national interest that we should try to educate all citizens so that they can learn to think critically. Not just for their personal good, but for the good of the rest of us too.

Look at what has happened around the world in places devastated by economic embargoes, one-sided warfare, or the HIV/AIDS epidemic. Or, consider the problem of global climate change, and how important it is for all of us to cooperate with efforts to curtail our use of fossil fuels to reduce emissions of harmful greenhouse gases.

Consider the “cultural revolutions” undertaken by totalitarian rulers. Notice how in virtually every case absolutist and dictatorial despots seek ever more severe limitations on free expression. They label “liberal” intellectuals “dangers to society” and expel “radical” professors from teaching posts because they might “corrupt the youth.” Some use the power of their governmental or religious authority to crush not only their opposition but the moderates as well — all in the name of maintaining the purity of their movement. They intimidate journalists and those media outlets which dare to comment “negatively” on their political and cultural goals or their heavy-handed methods.

The historical evidence is there for us to see what happens when schools are closed or converted from places of education to places for indoctrination. We know what happens when children are no longer being taught truth-seeking, the skills of good reasoning, or the lessons of human history and basic science: Cultures disintegrate; communities collapse; the machinery of civilization fails; massive numbers of people die; and sooner or later social and political chaos ensues.

Or, imagine a media, a religious or political hegemony which cultivated, instead of critical thinking, all the opposite dispositions? Or consider if that hegemony reinforced uncritical, impulsive decision making and the “ready-shoot-aim” approach to executive action. Imagine governmental structures, administrators, and community leaders who, instead of encouraging critical thinking, were content to make knowingly irrational, illogical, prejudicial, unreflective, short-sighted, and unreasonable decisions.

How long might it take for the people in this society which does not value critical thinking to be at serious risk of foolishly harming themselves and each other?

The news too often reports about hate groups, wanton shooting, terrorists, and violently extreme political, ideological, or religious zealots. Education which includes a good measure of critical thinking skills and dispositions like truth-seeking and open-mindedness, is a problem for terrorists and extremists of every stripe because terrorists and extremists want to control of what people think. They are ideologists of the worst kind. Their methods include indoctrination, intimidation, and the strictest authoritarian orthodoxy. In the “black-and-white” world of “us vs. them” a good education would mean that the people might begin to think for themselves. And that is something these extremists do not want.

History shows that assaults on learning, whether by book burning, exile of intellectuals, or regulations aimed at suppressing research and frustrating the fair-minded, evidence-based, and unfettered pursuit of knowledge, can happen wherever and whenever people are not vigilant defenders of open, objective, and independent inquiry.

Does this mean that society should place an extremely high value on critical thinking?

Absolutely!

Does this mean society has the right to force someone to learn to think critically?

Maybe. But, really, should we have to?

“Critical Thinking for Life: Valuing, Measuring, and Training Critical Thinking in All its Forms,” describes the work of Drs. Peter A. and Noreen C. Facione. The essay can be found in the Spring 2013 issue of Inquiry (Vol. XXVIII, No.1).

They and their co-investigators have been engaged in research and teaching about reasoning, decision-making, and effective individual and group thinking processes since 1967. Over the years they developed instruments to measure the core skills and habits of mind of effective thinking, these instruments are now in use in many different languages throughout the world. Since 1992 they have presented hundreds of workshops about effective teaching for thinking and about leadership, decision-making, leadership development, planning and budgeting, and learning outcomes assessment at national and international professional association meetings, business organizations, military bases, healthcare agencies, and on college and university throughout the nation.

What is Critical Thinking?

Many researchers, including Facione, Simpson and Courtneay, Banning, Brookfield, Ornstein and Hunkins, Sternberg, Ennis, and Lipman, have defined critical thinking (CT). Researchers debate whether critical thinking can be learned or if it's a developmental process regulated by motivations, dispositions, and personality traits. Despite differences of opinion, many researchers agree that critical thinking is "Purposeful, self-regulatory judgment which results in interpretation, analysis, evaluation, and inference, as well as explanation of the evidential, conceptual, methodological, criteriological or contextual considerations upon which judgment is based. 11

Critical thinking is also regarded as intellectually engaged, skillful, and responsible thinking that facilitates good judgment because it requires the application of assumptions, knowledge, competence, and the ability to challenge one's own thinking. Critical thinking requires the use of self-correction and monitoring to judge the rationality of thinking as well as reflexivity. When using critical thinking, individuals step back and reflect on the quality of that thinking. Simpson and Courtneay point out that critical thinking processes require active argumentation, initiative, reasoning, envisioning and analyzing complex alternatives, and making contingency-related value judgment. 12

According to Banning, critical thinking involves scrutinizing, differentiating, and appraising information as well as reflecting on information to make judgments that will inform clinical decisions. 13  Brookfield asserts that identifying and challenging assumptions and analyzing assumptions for validity are essential to critical thinking skills. He also suggested that because critical thinkers possess curiosity and skepticism, they are more likely to be motivated to provide solutions that resolve contradictions. 14

Others such as Ornstein and Hunkins suggest that critical thinking and thinking skills refer to problem-solving and other related behaviors. 15  For a number of years, dental educators thought teaching problem-solving skills was akin to teaching critical thinking skills. While teaching problem-solving skills is important to the process of learning how to use critical thinking skills, in the absence of other learning activities it may not be enough.

Sternberg, Ennis, and Lipman assert that critical thinking skills are not a fixed entity but a form of intelligence that can be taught. 16-19  The ability to develop critical thinking skills may be likened to Piaget's concrete and formal operations. If students have not yet reached the formal operations stage, their ability to use critical thinking skills may be limited by an inability to handle abstract ideas. It is important to remember that Piaget's stages of cognitive development are also linked to intellectual potential and environmental experiences. If the learning environment is crucial to the development of critical thinking skills, what instructional strategies can be used to promote critical thinking?

Sternberg asserts that critical thinking involves complex mental operations that cannot be broken into discrete styles of thinking. He claims that CT involves students' total intellectual functioning, not a narrowly defined set of skills. He postulates that there are three mental processes fostering critical thinking: meta-components, performance components, and knowledge-acquisition strategies. 20  Meta-components refer to higher-order mental processes that individuals use to plan, monitor, and evaluate what they do. Performance components refer to the actual steps taken or strategies used, while knowledge-acquisition strategies refer to the ways in which individuals relate old to new material and apply new material. Sternberg does not specify a "how" approach to teaching and learning critical thinking skills. Instead, he provides general guidelines for developing or selecting a program or curriculum that will foster CTS. Interestingly, although not surprisingly, Sternberg states that students are not adequately prepared for the problems and critical thinking tasks they will face in everyday life because they are not taught these skills in their formative years. 21  Tasks that stress right answers or truth telling or use objectively scored tests are generally removed from real-world relevance. Thus, it is particularly important that all aspects of dental educational curriculum stress real-world practice, the importance of oral health care, and the relationship of overall oral health care to systemic health by teaching students how to use critical thinking skills.

Lipman, like Sternberg, does not specify a "how to" approach. However, he makes clear distinctions between ordinary thinking and critical thinking. He explains that ordinary thinking is simplistic thinking because it does not rely upon the use of standards or criteria. Examples of ordinary thinking are guessing, believing, and supposing. Lipman describes critical thinking as a complex process based on standards of objectivity, utility, or consistency in which students can reflect upon the certainty of their thinking because critical thinking is self-correcting. 22  In order words, students can defend their thinking with evidence. Ennis asserts that to help students develop critical thinking skills, teachers must understand the cognitive processes that constitute critical thinking and use instructional activities that will develop these processes. He recommends instructors teach students how to define and clarify information, ask appropriate questions to clarify or challenge statements or beliefs, judge the credibility of sources, and solve problems by predicting probable outcomes through logic or deduction. Ennis also suggests that critical thinkers demonstrate particular attributes. Critical thinkers tend to:

Critical thinkers use these skills appropriately and usually without prompting. They are generally predisposed to think critically and to evaluate the outcome of their thought processes. 24

Instructional Strategies and Critical Thinking

Researchers have asserted that how educators teach has a direct influence on what is learned. 25  Thus, the instructional strategies selected must be appropriate to the desired outcomes. For example, strategies of inquiry are contingent upon the problem being investigated and the targeted concepts, so it is essential that they be integrated with the associated processes of inquiry in order for students to see how new knowledge evolves. 26  Researchers have also recommended eliminating superfluous activities and repetitious content and expanding learner-centered active forms of experiences to promote critical thinking skills. 27  If the goal is for students to use critical thinking skills, then the following opportunities should constitute the majority of learning activities:

     a) Engaging in problem-based learning      b) Analyzing case-based scenarios      c) Engaging in debates, role-play, argument mapping, thinking aloud, and simulation among others 28  

The benefit of engaging students in learning experiences that utilize critical thinking skills is the public nature of their thinking. When students engage in CTS, they have an opportunity to examine tacitly held knowledge of one another, make knowledge and think explicitly, respond to questions and comments, and clarify their thinking processes. 29

Several researchers stated the types of instructional strategies that may be used to promote students' critical thinking skills. Weerts suggested that working in groups might reduce students' stress while trying to answer difficult questions. She points out that working together may result in better answers than working alone. 30  Many dental educators might eschew the notion of using groups. However, it is important to acknowledge that even in classes of 80 to 100 dental students, groups of six to eight students could be developed to facilitate learning and inquiry. These groups could be responsible for answering questions about readings by being called upon randomly during class time. For example, instructors can consider writing three to four focus questions that accompany the readings to guide student comprehension. Instructors could also tell students that they should to be able to answer those questions in class. In this way, students can be held responsible for learning some of this discrete information before class. Rather than having the instructor feel responsible for "telling" students what they should know, the instructor can elicit the key concepts from students. Class time can then be used to present a case where the concept is illustrated, and students can work in groups to analyze how that concept is operationalized rather than receiving discrete knowledge through a lecture. Weerts also suggests that student groups can work together and develop critical thinking skills by:

     Identifying issues      Gathering authoritative sources      Identifying potential treatments      Presenting competing points of view      Weighing modalities in light of the presenting case and then agreeing upon the treatment plan 31  

To ensure that students are developing appropriate skills, the instructor and students can use a Likert scale to rate each other on the following criteria:

     Accuracy and relevancy of supporting evidence      Credibility of authoritative knowledge      Depth and breadth of thought      Clarity and soundness of responses

Hendricson et al. suggest several active learning strategies that can be used to develop students' critical thinking skills.

Van Gelder concurs with Hendricson et al. that critical thinking must be deliberately practiced with the intent to improve performance; however, he states that CT is hard and human beings are not naturally critical. 33  Shermer agrees and describes human beings as "pattern-seeking, story-telling animals ... [who] like things to make sense, and the kinds of sense we grasp most easily are simple familiar patterns or narratives" (p. 42). 34  This penchant for the familiar affects how curriculum is designed and implemented.

As a type of thinking that eschews the uncritical acceptance of information, critical thinking should be a deliberate part of the curriculum. Moreover, exposing students to good examples is insufficient to developing critical thinking skills. Students must demonstrate the ability to transfer critical thinking skills from one situation to another. As Kuhn writes:

"The best approach . . . may be to work from both ends at once-from a bottom-up anchoring in the regular practice [of what is being taught] so that skills are exercised, strengthened and consolidated as well as from a top-down fostering of understanding and intellectual values that play a major role in whether these skills will be used." (p. 24). 35

Kuhn's point has implications for teaching critical thinking skills in the basic science courses as well. Even though students are heavily immersed in learning a tremendous amount of information, they should still be presented with critical thinking learning experiences that embed concepts in actual practice-based scenarios. 36

Argument mapping

Van Gelder suggests that students' critical thinking skills improve faster when instruction is based upon argument mapping. He asserts that when arguments are presented in diagrammatic form, students are more capable of following critical thinking procedures. Because argument maps are visual and more transparent, they make the core operations of critical thinking more straightforward. Van Gelder cautions, however, that belief preservation is a human tendency. He states that individuals tend to make evidence secondary to beliefs. Thus, critical thinking runs counter to human tendencies. Humans tend to seek evidence that supports beliefs and ignore evidence that goes against beliefs. Ideally, critical thinkers will recognize this, put extra effort into searching for evidence that contradicts their own beliefs and cultivate a willingness to change when evidence to the contrary begins to mount. 37

To apply argument mapping to clinical reasoning, consider Case #1.

Case #1-Differing Views on Patient Treatment

A 60-year-old woman has internal resorption of the left maxillary lateral incisor. Radiographic exams reveal that saving the tooth is questionable. The student dentist recommends to Professor Marlin that the patient receive a fixed partial denture (FPD). Marlin confers with Professor James, and James recommends a removable partial denture (RPD).

• The students are instructed to use argument mapping to explain the phenomenon.
• Next, students are asked to write about the contradictions that differentiate viewpoints about FPD and RPD and to write about the counterarguments.
• 3. Finally, students are to identify their treatment decisions and provide evidence that supports or justifies their assertions.

Think-aloud seminar

Lee and Ryan-Wenger recommend the use of the "think-aloud seminar" as a teaching tool. Students are presented with a case and asked relevant questions regarding symptoms and presenting signs. Using this approach, students can exclude underlying pathologies based upon the presentation. This process of excluding potential diagnoses aids students' critical thinking by encouraging them to openly verbalize the rationales behind their opinions. 38

Wong and Chung used simulation to develop diagnostic reasoning skills among nursing students. Students were asked to consider the etiological factors, presenting symptoms, and clinical signs of a patient who presented with a particular condition. As they examined the underlying patholophysiology, the CTS they developed were "assessing duration" and "frequency of symptoms and additional triggers." They also were expected to review their understanding of the possible pathophysiological significance. The next set of CTS they focused on was "considering the pros and cons of treatments" and "drug actions and the possible side effects on the patient." Finally they explored the efficacy of the outcomes. CTS developed in this phase were "determining the success of the treatment," "determining complications," "considering the time it took to resolve the clinical signs and symptoms," and "considering reasons for the development of symptoms." 39

Other strategies

Other strategies that can promote critical thinking include particular behaviors, especially asking questions.

Table 3. Strategies that Promote Critical Thinking

Asking particular types of questions also promotes critical thinking.

  Table 4. Questions that Promote Critical Thinking

Also, Facione and Facione (1996) recommend that students begin analyzing their own thinking. For example, "If you were teaching a colleague about this situation, how would you lead him or her through the issues?" 41

Logical Fallacies

While faculty strive to develop students' abilities to use critical thinking, it is also important to communicate the logical fallacies students may demonstrate in their writing or speaking. Engel provides an overview that illustrates the common fallacies. 42 Three common types of fallacies are shown in Table 5.

Table 5. Common Logical Fallacies (Adapted from Engel, 1990)

Allowing Time for Reflection

Teaching students how to use critical thinking skills shifts teaching from a model that largely ignores thinking to an approach that renders it pervasive 43 When content is didactically taught, it is treated as static and students are unlikely to question or think it through. They tend to rely on rote memorization without grasping the logic, supporting evidence and application of what they are trying to memorize. Students who learn through a critical thinking process truly learn content. At every level, students need to learn how to:

Ask questions precisely, define contexts and purposes, pursue relevant information, analyze key concepts, derive sound inferences, generate good reasons, recognize questionable assumptions, trace important implications, and think empathetically within different points of view (p. 20). 44

Critical thinking is difficult and requires overt practice using a variety of learning activities across the dental curriculum. It is also important to recognize the role that reflection plays in its development. Students need time to think about what they are learning and reflect upon that information. However, what they are learning must have an impact on their feelings in order for critical thinking to occur.

Emotions and Critical Thinking 

The role of emotion in learning to use critical thinking skills is yet another area that necessitates research inquiry. As Zull suggests, if we want students to retain concepts we must allow them to put things into their own words, verbally and in writing. 45  Give students time to think before speaking and better construct ideas in their own words. Processing information takes time; stating one's thinking correctly also takes time. If a student cannot do this alone, we can give him or her the opportunity to discuss questions with others. Giving students time to reflect is giving them time to make connections.

Zull explains the process that takes place within the brain. First, the sensory cortex receives sensory input or concrete experiences. Next, the back integrative cortex tries to create meaning and images during the human process of reflection. The frontal integrative cortex is responsible for short-term memory and problem solving, making decisions and language, and making judgments and evaluations. This activity is akin to how learners handle abstractions-manipulating images and language to create new mental arrangements. The motor cortex triggers all coordinated and voluntary muscle contractions. This matches with the action that completes the learning cycle-actively testing abstractions and converting ideas into physical actions. The brain visualizes items in small amounts and all information arrives at the same time, producing an outline of objects and features in the visual field. 46 Thus, the brain can fully see great detail and nuance. Converting ideas into images helps students learn. Images enhance recall and aid in discovery. Sometimes the best teaching is just showing the student how.

To ensure that students learn, educators need to limit the amount of information they give. Instructors should limit or condense to three or four pieces the amount of information they want students to process.

The amygdala is responsible for screening experiences. 47  If something is recognized as dangerous, the amygdale will instinctively cause the body to "freeze." When a student first encounters something new, he or she may have a somewhat negative reaction. The instructor needs to find a way for the student to move into a more positive emotional territory. 48  Making suggestions or showing examples can remind the student what he or she already knows, and then the student can hang newly acquired knowledge on that "scaffolding." The support given by the instructor allows the student some level of success. Recognizing his or her success helps the student feel more hope, interest, and curiosity. At this point, the student is able to assume more control of the learning process. Boyd (2002) concurs and states, "emotions ... constantly regulate what we experience as reality." She also points out, "The limbic system plays an important role in processing emotion and memory and therefore appears to be important in the transfer of short-term memory into long-term memory." 49  Engaging students emotionally and actively strengthens memory.

Teaching students to use CTS during instruction

There is some empirical evidence that a four-year undergraduate experience contributes to modest gains in overall CT. However, there is little scientific evidence that a single course, other than a critical thinking skills course makes a positive measurable difference. 50  Even in the case of a specific CTS course, the evidence is mixed. 51

Recent studies show that limited efforts to infuse critical thinking in instruction can lead to improved scores on the Cornell Critical Thinking Test Level Z, a test that is aimed at a sophisticated audience and measures six common critical thinking skills. 52  Allegrettti and Frederick (1995) reported pre- to post-test gains on the Cornell Z for a group of college seniors (n = 24) who took a capstone integrated psychology and philosophy course. 53  Solon (2001) found that a partial treatment group of psychology students (n = 26) improved their scores on the Cornell Z compared to a group of untreated humanities students (n = 26). The results were statistically significant (beyond .001). In 2003, Solon studied three groups to compare coursework effects and reported that the full treatment group (n = 25) significantly outscored both the partial (n = 25) and non-treatment (n = 25) groups on the Cornell Z test. 54  Solon (2007) reported that a group of introductory psychology students (n = 25) received a moderate infusion of critical thinking skills (10 hours instruction and 20 hours homework). Compared to the non-treatment group (n= 26), the experimental group significantly improved their scores on the Cornell Z test. 55  These findings suggest that even a moderate infusion of critical thinking skills instruction can result in enhanced reasoning skills without requiring a significant investment from the instructor. 56

Collins and Onwuegbuzie reported significant relationships between overall CTS and achievement in a graduate level research methodology course at the midterm (r = .34, p < .01) and final (r = .26, p < .01) stages. 57  Onwuegbuzie compared the CTS of master's and doctoral level students. He reported that doctoral level students (n = 19) obtained statistically higher overall CTS using the California Critical Thinking Skills Test than the masters' degree students (n = 101, t = -3.54, p < .01). The effect size (d = 0.92) associated with this difference was extremely large. 58

Teaching CTS requires instruction that uses higher order taxonomic skills. These skills require student demonstration or teacher usage of behaviors classified as analysis, evaluation, and creation (levels 4, 5, and 6 on Bloom's revised taxonomy). When teaching takes place at higher levels of learning, lower order behaviors such as remembering, understanding, and applying are subsumed within instruction. The following table lists behaviors common at each level of learning and examples of related dental education activities.

Table 6. Revised Bloom's Taxonomy, Sample Verbs, and Related Learning Activities 59

Making Critical Thinking Explicit

Teaching for critical thinking is a rational and intentional act. Typically, instructors cannot suddenly decide to teach CTS and develop an appropriate learning activity. An instructor must have a clear understanding of what CTS is, how it is implemented during instruction, and what strategies should be used during particular classroom and predoctoral clinical learning activities. Developing a repertoire of well-honed CTS activities appropriate to your specific discipline is advisable.

Also crucial to the teaching of CTS is an educator announcing to students he or she will teach CTS, how he or she intends to do so, and what will be required of the students as learners. It is important to have an explicit conversation with students about what CTS is, what it looks like, and how educators will model it so students can differentiate the teaching of CTS from lower level learning. Effective teaching of university-age students is characterized by collegial and collaborative processes, not instruction that is ambiguous. In ambiguous instruction, the learner does not know what to expect next or have a clear understanding of what behavioral or skill changes he or she should demonstrate as a result of teacher-student interaction. Teaching explicitly helps ensure that less re-teaching will be necessary. Both teachers and students know their responsibilities as instructors and learners.

Stages of Critical Thinking

Paul and Elder claim that individuals progress through predictable stages of unreflective, challenged, beginning, practicing, advanced, and master thinking. 60  They state that unless educators help students develop an intellectual vocabulary for discussing their thought processes and challenge them to identify the problems in their thinking, the students' cognitive processes will remain invisible to them. The implication for curriculum development: If instructors want students to develop critical thinking skills, then critical thinking must be integrated into the foundations of instruction.

It is also important to recognize that when patient care is task focused, it can obscure the bigger picture and become a barrier to the development of critical thinking skills. Individual personality, background, and position might also limit one's ability to think critically. Additionally, gender, age, religion, and socioeconomic status might influence the development of critical thinking skills. One of the biggest barriers to the development of CTS is our educational system. Although it is important to recognize these attributes as potential barriers, it is more important that dental educators establish the kind of learning environments that will foster the development of CTS.

Case #2-Why Are Mrs. Connor's Teeth Yellow?

Mrs. Connor, a 74-year-old white female, comes to your office as a new patient. She presents you with a complaint that her teeth have become yellowed and unattractive. Her husband died one year prior, and since then she has been drinking 8-10 cups of coffee daily. Her internist diagnosed anemia and high blood cholesterol. She is taking iron and Lipitor. She feels better since she began taking Lipitor, but feels her teeth are too yellow. She recently met a widower who invited her to dinner next week. She is worried about the appearance of her teeth.

• Working in groups of six, students are asked to write at least four hypotheses about why Mrs. Connor's teeth are yellow.
• Students must also determine if whiter teeth are important to the health and well being of geriatric patients.
• Students must discuss if there a relationship between the need of care and the use of dental services by older patients.
• A student group will then outline its recommendations and a rationale for the treatment plan to be presented to Mrs. Connor at her next dental appointment.

Teachers must recognize that not all students will apply critical thinking skills at the same rate they learn these skills. Thus, instructional methods and objectives need to match students' cognitive and experiential abilities while trying to stretch students to their growing edge. 61  Students' capacity for self-directed learning (SDL), which is required to implement reflective judgment, underlies many of the critical thinking skill dispositions. 62  There is evidence that the students who routinely use the "learn by doing" approach to explore problems develop more sophisticated SDL than students in lecture-based curricula. 63  The reflection element of critical thinking is considered essential to clinical judgment. 64  Tanner asserts that using the skills associated with reflective thinking prepares students for ill-structured or ambiguous problems that they are likely to encounter in clinical practice. 65

Problem-based learning (PBL) is a popular instructional strategy for promoting collaboration and reflection and negotiating different and individual constructions of knowledge. Some researchers assert that PBL is best used when problems are unsolvable or when they generate many individual constructions of knowledge that appear valid. 66  However, using only problem-based learning to teach critical thinking skills may not be enough. This instructional strategy does not necessarily equip students with the ability to analyze or critique a given situation or the information with which they are been provided. A variety of instructional strategies that give students the opportunity to think aloud, role play, prioritize alternatives, communicate conclusions effectively, simulate, or defend the logical basis of their thinking is recommended to foster students' ability to use critical thinking.

Asking students to apply their understanding of dental and medical knowledge to treatment planning and diagnosis is not an example of CTS. However, asking students to determine differential diagnoses of caries and periodontal disease among patients at various stages of lung cancer requires the ability to reason and justify particular treatment plans or demonstrate critical thinking skills. Habits of the students who demonstrate critical thinking are:

Case #3-Female with Erythroplakia

Mrs. Jacklin, a 40-year-old female, presents you with a history of SLE and erythroplakia on the left lateral border of the tongue. She states she is experiencing a burning sensation on her tongue. She asks why she is having this discomfort and what she can do to make the sore on her tongue go away. The oral exam shows that Mrs. Jacklin has poor oral hygiene and mild dry mouth (xerostomia) but is otherwise not in danger for oral health concerns.

• Working in groups of four, students are asked to locate the four most recent references on oral lesions.
• Using those resources, they are asked to write five or six reasons that the patient is experiencing a tongue lesion and determine what questions they should ask the patient about her personal and social history.
• Next, they identify questions to ask her about her medical history.
• Using the information they have acquired, they are asked to generate a list of potential treatment plans and the benefits and limitations of each plan.
• What should they tell the patient and why?

Critical thinking is not :

Critical thinking cannot be taught in a learning environment where the dental educator always lectures, tells students what ought to be undertaken during patient treatment, or shows students how to do a procedure correctly. Some habits of students who do not use critical thinking skills are:

Critical thinking skills can be developed with frequent practice and the use of ill-structured problems and situations that require the ability to recall useful knowledge quickly, use pattern recognition, discern pertinent information, think ahead, and anticipate outcomes and problems while remaining composed so that emotions do not hinder decisionmaking skills. However, it is important to recognize CTS do not develop spontaneously or with maturation. Since strong personality components underlie CT dispositions, what happens if students admitted to colleges of dentistry do not already possess these traits?

The essence of the independent mind lies not in what it thinks, but in how it thinks. —Christopher Hitchens, author and journalist

Critical Thinking

As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important of these skills is critical thinking. Critical thinking is important because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It’s a discipline-general thinking skill, not a thinking skill that’s reserved for a one subject alone or restricted to a particular content area. Of all your thinking skills, critical thinking may have the greatest value.

What Is Critical Thinking?

Critical thinking is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like, “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions, rather than simply memorizing facts or blindly accepting what you hear or read. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching.

Critical thinkers are curious and reflective people. They explore and probe new areas and seek knowledge, clarification, and solutions. They ask pertinent questions, evaluate statements and arguments, and distinguish between facts and opinion. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit lack of knowledge or understanding when needed. Critical thinkers are open to changing their mind. Perhaps most of all, they actively enjoy learning and view seeking new knowledge as a lifelong pursuit.

Thinking critically will help you develop more balanced arguments, express yourself clearly, read more critically, and glean important information efficiently. With critical thinking, you become a clearer thinker and problem solver.

The following video, from Lawrence Bland, presents the major concepts and benefits of critical thinking.

The Role of Logic in Critical Thinking

Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly-held belief or a new idea. With critical thinking, anything and everything is subject to question and examination for the purpose of logically constructing reasoned perspectives.

The word logic comes from the Ancient Greek logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and reasoning and strives to distinguish between good and bad reasoning or between truth and falsehood. Using logic, you can evaluate ideas or claims people make, make good decisions, and form sound beliefs about the world. [1] . Logical thinkers provide reasonable and appropriate evidence to support their claims, acknowledge the strengths of the opposing side’s position, actively investigate a variety of possible outcomes or new solutions, and use measured and objective language to present their positions.

Examine Arguments

Logical thinkers examine arguments from a variety of perspectives. When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and analyze the hard facts. You can use the spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the “hot” end of an argument (feelings, beliefs, cultural influences, and influences) from the “cold” end of an argument (scientific influences).

Clarify Thinking

When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this well is mainly a process of asking and answering logical, probing questions. Design your questions to fit your needs, but be sure to cover adequate ground.

• What is the purpose?
• What question are we trying to answer?
• What point of view is being expressed?
• What assumptions are we or others making?
• What are the facts and data we know, and how do we know them?
• What are the concepts we’re working with?
• What are the conclusions, and do they make sense?
• What are the implications?

Avoid Fallacies

You’ll also want to make sure you can avoid and spot logical fallacies. Fallacies are faults in thinking or illogical approaches used to persuade the other side. Statements such as, everyone else is doing it ca n be very persuasive even though they demonstrate faulty logic, in this case, the bandwagon appeal. Because these fallacies are always on the “hot” end of an argument, they can undermine your authority and weaken your position. Students shouldn’t park in the faculty lot because that lot is for faculty is another example of a logical fallacy, this time circular reasoning.

Consult the two websites below to identify and avoid some of the many kinds of logical fallacies:

Applying critical thinking

The following questions may apply to formulating a logical, reasoned perspective in the scenario below or any other situation:

• What is happening? Gather the basic information and begin to think of questions.
• Why is it important? Ask yourself why it’s significant and whether or not you agree.
• What don’t I see? Is there anything important missing?
• How do I know? Ask yourself where the information came from and how it was constructed.
• Who is saying it? What’s the position of the speaker and what is influencing them?
• What else? What if? What other ideas exist and are there other possibilities?

A man has a PhD in political science, and he works as a professor at a local college. His wife works at the college, too. They have three young children in the local school system, and their family is well known in the community. The man is now running for political office. Are his credentials and experience sufficient for entering public office? Will he be effective in the political office? Some voters might believe that his personal life and current job, on the surface, suggest he will do well in the position, and they will vote for him. In truth, the characteristics described don’t guarantee that the man will do a good job. The information is somewhat irrelevant. What else might you want to know? How about whether the man had already held a political office and done a good job? In this case, we want to ask, How much information is adequate in order to make a decision based on logic instead of assumptions?

Problem-Solving with Critical Thinking

For most people, a typical day is filled with critical thinking and problem-solving challenges. In fact, critical thinking and problem-solving go hand-in-hand. They both refer to using knowledge, facts, and data to solve problems effectively, but with problem-solving, you are specifically identifying, selecting, and defending your solution.

Applying the strategies described in the action checklist below can help you utilize critical thinking skills to solve problems.

Problem-solving can be an efficient and rewarding process, especially if you are organized and mindful of critical steps and strategies. Remember, too, to assume the attributes of a good critical thinker. If you are curious, reflective, knowledge-seeking, open to change, probing, organized, and ethical, your challenge or problem will be less of a hurdle, and you’ll be in a good position to find intelligent solutions.

 Developing Yourself As a Critical Thinker and Problem-Solver

Critical thinking is a fundamental skill for college students, but it should also be a lifelong pursuit that we continually refine. Below are additional strategies to develop yourself as a critical thinker in college and in everyday life:

• Reflect and practice : Always reflect on what you’ve learned. Is it true all the time? How did you arrive at your conclusions?
• Use wasted time : It’s certainly important to make time for relaxing, but if you find you are indulging in too much of a good thing, think about using your time more constructively. Determine when you do your best thinking and try to learn something new during that part of the day.
• Redefine the way you see things : It can be very uninteresting to always think the same way. Challenge yourself to see familiar things in new ways. Put yourself in someone else’s shoes and consider a certain situation from a different angle or perspective. If you’re trying to solve a problem, list all your concerns, such as what you need in order to solve it, who can help, and what some possible barriers might be. It’s often possible to reframe a problem as an opportunity. Try to find a solution where there seems to be none.
• Analyze the influences on your thinking and in your life : Why do you think or feel the way you do? Analyze your influences. Think about who in your life influences you. Do you feel or react a certain way because of social convention or because you believe it is what is expected of you? Try to break out of any molds that may be constricting you.
• Express yourself : Critical thinking also involves being able to express yourself clearly. Most important in expressing yourself clearly is stating one point at a time. You might be inclined to argue every thought, but you might have greater impact if you focus only on your main arguments. This will help others to follow your thinking clearly. For more abstract ideas, assume that your audience may not understand. Provide examples, analogies, or metaphors where you can.
• Enhance your wellness : It’s easier to think critically when you take care of your mental and physical health. Try taking 10-minute activity breaks to reach 30 to 60 minutes of physical activity each day . Try taking a break between classes and walk to the coffee shop that’s farthest away. Scheduling physical activity into your day can help lower stress and increase mental alertness.
• Do your most difficult work when you have the most energy: Think about the time of day you are most effective and have the most energy. Plan to do your most difficult thinking during these times.

Reflect on Critical Thinking

• Think about someone whom you consider to be a critical thinker (friend, professor, historical figure, etc). What qualities does he/she have?
• Review some of the critical thinking strategies discussed on this page. Choose one strategy that makes sense to you. How can you apply this critical thinking technique to your academic work?
• Habits of mind are attitudes and beliefs that influence how you approach the world (inquiring attitude, open mind, respect for truth, etc.). What is one habit of mind you would like to actively develop over the next year? How will you develop a daily practice to cultivate this habit?

Cultivate Critical Habits of Mind

Earlier in this text we discussed, “habits of mind,” the personal commitments, values, and standards people have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence. Other important habits of mind include being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always, especially, questioning your own conclusions. In their quest towards developing an intellectual work ethic, critical thinkers constantly try to work these qualities into their daily lives.

 problem-solving with critical thinking

Below are some examples of using critical thinking to problem-solve. Can you think of additional action steps to apply to the following situations? You may want to look back to Chapter 2 “Defining Goals” to utilize the five step problem solving strategy described there.

• Your friend was upset and said some unkind words to you, which has put a crimp in the relationship. You try to see through the angry behaviors to determine how you might best support your friend and help bring the relationship back to a comfortable spot.
• Your campus club has been languishing on account of lack of participation and funds. The new club president, though, is a marketing major and has identified some strategies to interest students in joining and supporting the club. Implementation is forthcoming.
• Your final art class project challenges you to conceptualize form in new ways. On the last day of class when students present their projects, you describe the techniques you used to fulfill the assignment. You explain why and how you selected that approach.
• Your math professor sees that the class is not quite grasping a concept. She uses clever questioning to dispel anxiety and guide you to new understanding of the concept.
• You have a job interview for a position that you feel you are only partially qualified for, although you really want the job and you are excited about the prospects. You analyze how you will explain your skills and experiences in a way to show that you are a good match for the prospective employer.
• You are doing well in college, and most of your college and living expenses are covered. But there are some gaps between what you want and what you feel you can afford. You analyze your income, savings, and budget to better calculate what you will need to stay in college and maintain your desired level of spending.
