The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

9.1 Developing a Strong, Clear Thesis Statement

Learning objectives.

  • Develop a strong, clear thesis statement with the proper elements.
  • Revise your thesis statement.

Have you ever known a person who was not very good at telling stories? You probably had trouble following his train of thought as he jumped around from point to point, either being too brief in places that needed further explanation or providing too many details on a meaningless element. Maybe he told the end of the story first, then moved to the beginning and later added details to the middle. His ideas were probably scattered, and the story did not flow very well. When the story was over, you probably had many questions.

Just as a personal anecdote can be a disorganized mess, an essay can fall into the same trap of being out of order and confusing. That is why writers need a thesis statement to provide a specific focus for their essay and to organize what they are about to discuss in the body.

Just like a topic sentence summarizes a single paragraph, the thesis statement summarizes an entire essay. It tells the reader the point you want to make in your essay, while the essay itself supports that point. It is like a signpost that signals the essay’s destination. You should form your thesis before you begin to organize an essay, but you may find that it needs revision as the essay develops.

Elements of a Thesis Statement

For every essay you write, you must focus on a central idea. This idea stems from a topic you have chosen or been assigned or from a question your teacher has asked. It is not enough merely to discuss a general topic or simply answer a question with a yes or no. You have to form a specific opinion, and then articulate that into a controlling idea —the main idea upon which you build your thesis.

Remember that a thesis is not the topic itself, but rather your interpretation of the question or subject. For whatever topic your professor gives you, you must ask yourself, “What do I want to say about it?” Asking and then answering this question is vital to forming a thesis that is precise, forceful and confident.

A thesis is one sentence long and appears toward the end of your introduction. It is specific and focuses on one to three points of a single idea—points that are able to be demonstrated in the body. It forecasts the content of the essay and suggests how you will organize your information. Remember that a thesis statement does not summarize an issue but rather dissects it.

A Strong Thesis Statement

A strong thesis statement contains the following qualities.

Specificity. A thesis statement must concentrate on a specific area of a general topic. As you may recall, the creation of a thesis statement begins when you choose a broad subject and then narrow down its parts until you pinpoint a specific aspect of that topic. For example, health care is a broad topic, but a proper thesis statement would focus on a specific area of that topic, such as options for individuals without health care coverage.

Precision. A strong thesis statement must be precise enough to allow for a coherent argument and to remain focused on the topic. If the specific topic is options for individuals without health care coverage, then your precise thesis statement must make an exact claim about it, such as that limited options exist for those who are uninsured by their employers. You must further pinpoint what you are going to discuss regarding these limited effects, such as whom they affect and what the cause is.

Ability to be argued. A thesis statement must present a relevant and specific argument. A factual statement often is not considered arguable. Be sure your thesis statement contains a point of view that can be supported with evidence.

Ability to be demonstrated. For any claim you make in your thesis, you must be able to provide reasons and examples for your opinion. You can rely on personal observations in order to do this, or you can consult outside sources to demonstrate that what you assert is valid. A worthy argument is backed by examples and details.

Forcefulness. A thesis statement that is forceful shows readers that you are, in fact, making an argument. The tone is assertive and takes a stance that others might oppose.

Confidence. In addition to using force in your thesis statement, you must also use confidence in your claim. Phrases such as I feel or I believe actually weaken the readers’ sense of your confidence because these phrases imply that you are the only person who feels the way you do. In other words, your stance has insufficient backing. Taking an authoritative stance on the matter persuades your readers to have faith in your argument and open their minds to what you have to say.

Even in a personal essay that allows the use of first person, your thesis should not contain phrases such as in my opinion or I believe . These statements reduce your credibility and weaken your argument. Your opinion is more convincing when you use a firm attitude.

On a separate sheet of paper, write a thesis statement for each of the following topics. Remember to make each statement specific, precise, demonstrable, forceful and confident.

  • Texting while driving
  • The legal drinking age in the United States
  • Steroid use among professional athletes

Examples of Appropriate Thesis Statements

Each of the following thesis statements meets several of the following requirements:

  • Specificity
  • Ability to be argued
  • Ability to be demonstrated
  • Forcefulness
  • The societal and personal struggles of Troy Maxon in the play Fences symbolize the challenge of black males who lived through segregation and integration in the United States.
  • Closing all American borders for a period of five years is one solution that will tackle illegal immigration.
  • Shakespeare’s use of dramatic irony in Romeo and Juliet spoils the outcome for the audience and weakens the plot.
  • J. D. Salinger’s character in Catcher in the Rye , Holden Caulfield, is a confused rebel who voices his disgust with phonies, yet in an effort to protect himself, he acts like a phony on many occasions.
  • Compared to an absolute divorce, no-fault divorce is less expensive, promotes fairer settlements, and reflects a more realistic view of the causes for marital breakdown.
  • Exposing children from an early age to the dangers of drug abuse is a sure method of preventing future drug addicts.
  • In today’s crumbling job market, a high school diploma is not significant enough education to land a stable, lucrative job.

You can find thesis statements in many places, such as in the news; in the opinions of friends, coworkers or teachers; and even in songs you hear on the radio. Become aware of thesis statements in everyday life by paying attention to people’s opinions and their reasons for those opinions. Pay attention to your own everyday thesis statements as well, as these can become material for future essays.

Now that you have read about the contents of a good thesis statement and have seen examples, take a look at the pitfalls to avoid when composing your own thesis:

A thesis is weak when it is simply a declaration of your subject or a description of what you will discuss in your essay.

Weak thesis statement: My paper will explain why imagination is more important than knowledge.

A thesis is weak when it makes an unreasonable or outrageous claim or insults the opposing side.

Weak thesis statement: Religious radicals across America are trying to legislate their Puritanical beliefs by banning required high school books.

A thesis is weak when it contains an obvious fact or something that no one can disagree with or provides a dead end.

Weak thesis statement: Advertising companies use sex to sell their products.

A thesis is weak when the statement is too broad.

Weak thesis statement: The life of Abraham Lincoln was long and challenging.

Read the following thesis statements. On a separate piece of paper, identify each as weak or strong. For those that are weak, list the reasons why. Then revise the weak statements so that they conform to the requirements of a strong thesis.

  • The subject of this paper is my experience with ferrets as pets.
  • The government must expand its funding for research on renewable energy resources in order to prepare for the impending end of oil.
  • Edgar Allan Poe was a poet who lived in Baltimore during the nineteenth century.
  • In this essay, I will give you lots of reasons why slot machines should not be legalized in Baltimore.
  • Despite his promises during his campaign, President Kennedy took few executive measures to support civil rights legislation.
  • Because many children’s toys have potential safety hazards that could lead to injury, it is clear that not all children’s toys are safe.
  • My experience with young children has taught me that I want to be a disciplinary parent because I believe that a child without discipline can be a parent’s worst nightmare.

Writing at Work

Often in your career, you will need to ask your boss for something through an e-mail. Just as a thesis statement organizes an essay, it can also organize your e-mail request. While your e-mail will be shorter than an essay, using a thesis statement in your first paragraph quickly lets your boss know what you are asking for, why it is necessary, and what the benefits are. In short body paragraphs, you can provide the essential information needed to expand upon your request.

Thesis Statement Revision

Your thesis will probably change as you write, so you will need to modify it to reflect exactly what you have discussed in your essay. Remember from Chapter 8 “The Writing Process: How Do I Begin?” that your thesis statement begins as a working thesis statement , an indefinite statement that you make about your topic early in the writing process for the purpose of planning and guiding your writing.

Working thesis statements often become stronger as you gather information and form new opinions and reasons for those opinions. Revision helps you strengthen your thesis so that it matches what you have expressed in the body of the paper.

The best way to revise your thesis statement is to ask questions about it and then examine the answers to those questions. By challenging your own ideas and forming definite reasons for those ideas, you grow closer to a more precise point of view, which you can then incorporate into your thesis statement.

Ways to Revise Your Thesis

You can cut down on irrelevant aspects and revise your thesis by taking the following steps:

1. Pinpoint and replace all nonspecific words, such as people , everything , society , or life , with more precise words in order to reduce any vagueness.

Working thesis: Young people have to work hard to succeed in life.

Revised thesis: Recent college graduates must have discipline and persistence in order to find and maintain a stable job in which they can use and be appreciated for their talents.

The revised thesis makes a more specific statement about success and what it means to work hard. The original includes too broad a range of people and does not define exactly what success entails. By replacing those general words like people and work hard , the writer can better focus his or her research and gain more direction in his or her writing.

2. Clarify ideas that need explanation by asking yourself questions that narrow your thesis.

Working thesis: The welfare system is a joke.

Revised thesis: The welfare system keeps a socioeconomic class from gaining employment by alluring members of that class with unearned income, instead of programs to improve their education and skill sets.

A joke means many things to many people. Readers bring all sorts of backgrounds and perspectives to the reading process and would need clarification for a word so vague. This expression may also be too informal for the selected audience. By asking questions, the writer can devise a more precise and appropriate explanation for joke . The writer should ask himself or herself questions similar to the 5WH questions. (See Chapter 8 “The Writing Process: How Do I Begin?” for more information on the 5WH questions.) By incorporating the answers to these questions into a thesis statement, the writer more accurately defines his or her stance, which will better guide the writing of the essay.

3. Replace any linking verbs with action verbs. Linking verbs are forms of the verb to be , a verb that simply states that a situation exists.

Working thesis: Kansas City schoolteachers are not paid enough.

Revised thesis: The Kansas City legislature cannot afford to pay its educators, resulting in job cuts and resignations in a district that sorely needs highly qualified and dedicated teachers.

The linking verb in this working thesis statement is the word are . Linking verbs often make thesis statements weak because they do not express action. Rather, they connect words and phrases to the second half of the sentence. Readers might wonder, “Why are they not paid enough?” But this statement does not compel them to ask many more questions. The writer should ask himself or herself questions in order to replace the linking verb with an action verb, thus forming a stronger thesis statement, one that takes a more definitive stance on the issue:

  • Who is not paying the teachers enough?
  • What is considered “enough”?
  • What is the problem?
  • What are the results

4. Omit any general claims that are hard to support.

Working thesis: Today’s teenage girls are too sexualized.

Revised thesis: Teenage girls who are captivated by the sexual images on MTV are conditioned to believe that a woman’s worth depends on her sensuality, a feeling that harms their self-esteem and behavior.

It is true that some young women in today’s society are more sexualized than in the past, but that is not true for all girls. Many girls have strict parents, dress appropriately, and do not engage in sexual activity while in middle school and high school. The writer of this thesis should ask the following questions:

  • Which teenage girls?
  • What constitutes “too” sexualized?
  • Why are they behaving that way?
  • Where does this behavior show up?
  • What are the repercussions?

In the first section of Chapter 8 “The Writing Process: How Do I Begin?” , you determined your purpose for writing and your audience. You then completed a freewriting exercise about an event you recently experienced and chose a general topic to write about. Using that general topic, you then narrowed it down by answering the 5WH questions. After you answered these questions, you chose one of the three methods of prewriting and gathered possible supporting points for your working thesis statement.

Now, on a separate sheet of paper, write down your working thesis statement. Identify any weaknesses in this sentence and revise the statement to reflect the elements of a strong thesis statement. Make sure it is specific, precise, arguable, demonstrable, forceful, and confident.

Collaboration

Please share with a classmate and compare your answers.

In your career you may have to write a project proposal that focuses on a particular problem in your company, such as reinforcing the tardiness policy. The proposal would aim to fix the problem; using a thesis statement would clearly state the boundaries of the problem and tell the goals of the project. After writing the proposal, you may find that the thesis needs revision to reflect exactly what is expressed in the body. Using the techniques from this chapter would apply to revising that thesis.

Key Takeaways

  • Proper essays require a thesis statement to provide a specific focus and suggest how the essay will be organized.
  • A thesis statement is your interpretation of the subject, not the topic itself.
  • A strong thesis is specific, precise, forceful, confident, and is able to be demonstrated.
  • A strong thesis challenges readers with a point of view that can be debated and can be supported with evidence.
  • A weak thesis is simply a declaration of your topic or contains an obvious fact that cannot be argued.
  • Depending on your topic, it may or may not be appropriate to use first person point of view.
  • Revise your thesis by ensuring all words are specific, all ideas are exact, and all verbs express action.

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.  

Broad thesis (arguable, but difficult to support with evidence) 

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.  

Arguable thesis with analytical claim 

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.  

Arguable thesis with normative claim 

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.  

Questions to ask about your thesis 

  • Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?  
  • Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?  
  • Is the thesis complex enough to require a whole essay's worth of argument?  
  • Is the thesis supportable with evidence from the text rather than with generalizations or outside research?  
  • Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

Simply defined, a thesis is an extended argument. To pass, a thesis must demonstrate logical, structured, and defensible reasoning based on credible and verifiable evidence presented in such a way that it makes an original contribution to knowledge, as judged by experts in the field. Among the many types of scholarly productions, theses are an oddity: each one is different, and there are no standard or generic constructions. Most of those who supervise theses have written just one, and, despite the effort they take to produce, the only people who carefully read a given thesis are the project supervisors, the examiners, and an otherwise rather select audience of specialized academics.

How to prepare an excellent thesis defense

Thesis defence

What is a thesis defense?

How long is a thesis defense, what happens at a thesis defense, your presentation, questions from the committee, 6 tips to help you prepare for your thesis defense, 1. anticipate questions and prepare for them, 2. dress for success, 3. ask for help, as needed, 4. have a backup plan, 5. prepare for the possibility that you might not know an answer, 6. de-stress before, during, and after, frequently asked questions about preparing an excellent thesis defense, related articles.

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

  • Check with your department about requirements and timing.
  • Re-read your thesis.
  • Anticipate questions and prepare for them.
  • Create a back-up plan to deal with technology hiccups.
  • Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

  • your presentation of around 20-30 minutes
  • questions from the committee
  • questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

  • preparing the room of the day of defense
  • setting up equipment for the presentation
  • preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

  • Try meditational breathing right before your defense.
  • Get plenty of exercise and sleep in the weeks prior to your defense.
  • Have your clothes or other items you need ready to go the night before.
  • During your defense, allow yourself to process each question before answering.
  • Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

Argumentative thesis statements, learning objective.

  • Recognize an arguable thesis

Below are some of the key features of an argumentative thesis statement.

An argumentative thesis is . . .

An argumentative thesis must make a claim about which reasonable people can disagree. Statements of fact or areas of general agreement cannot be argumentative theses because few people disagree about them.

Junk food is bad for your health is not a debatable thesis. Most people would agree that junk food is bad for your health.

Because junk food is bad for your health, the size of sodas offered at fast-food restaurants should be regulated by the federal government is a debatable thesis.  Reasonable people could agree or disagree with the statement.

An argumentative thesis takes a position, asserting the writer’s stance. Questions, vague statements, or quotations from others are not argumentative theses because they do not assert the writer’s viewpoint.

Federal immigration law is a tough issue about which many people disagree is not an arguable thesis because it does not assert a position.

Federal immigration enforcement law needs to be overhauled because it puts undue constraints on state and local police is an argumentative thesis because it asserts a position that immigration enforcement law needs to be changed.

An argumentative thesis must make a claim that is logical and possible. Claims that are outrageous or impossible are not argumentative theses.

City council members stink and should be thrown in jail is not an argumentative thesis. City council members’ ineffectiveness is not a reason to send them to jail.

City council members should be term limited to prevent one group or party from maintaining control indefinitely is an arguable thesis because term limits are possible, and shared political control is a reasonable goal.

Evidence Based

An argumentative thesis must be able to be supported by evidence. Claims that presuppose value systems, morals, or religious beliefs cannot be supported with evidence and therefore are not argumentative theses.

Individuals convicted of murder will go to hell when they die is not an argumentative thesis because its support rests on religious beliefs or values rather than evidence.

Rehabilitation programs for individuals serving life sentences should be funded because these programs reduce violence within prisons is an argumentative thesis because evidence such as case studies and statistics can be used to support it.

An argumentative thesis must be focused and narrow. A focused, narrow claim is clearer, more able to be supported with evidence, and more persuasive than a broad, general claim.

The federal government should overhaul the U.S. tax code is not an effective argumentative thesis because it is too general (What part of the government? Which tax codes? What sections of those tax codes?) and would require an overwhelming amount of evidence to be fully supported.

The U.S. House of Representative should vote to repeal the federal estate tax because the revenue generated by that tax is negligible is an effective argumentative thesis because it identifies a specific actor and action and can be fully supported with evidence about the amount of revenue the estate tax generates.
