Writing Tips: Thesis Statements
Defining the Thesis Statement
What is a thesis statement?
Every paper you write should have a main point, a main idea, or central message. The argument(s) you make in your paper should reflect this main idea. The sentence that captures your position on this main idea is what we call a thesis statement.
How long does it need to be?
A thesis statement focuses your ideas into one or two sentences. It should present the topic of your paper and also make a comment about your position in relation to the topic. Your thesis statement should tell your reader what the paper is about and also help guide your writing and keep your argument focused.
Questions to Ask When Formulating Your Thesis
Where is your thesis statement?
You should provide a thesis early in your essay -- in the introduction, or in longer essays in the second paragraph -- in order to establish your position and give your reader a sense of direction.
Tip: In order to write a successful thesis statement:
- Avoid burying a great thesis statement in the middle of a paragraph or late in the paper.
- Be as clear and as specific as possible; avoid vague words.
- Indicate the point of your paper but avoid sentence structures like, “The point of my paper is…”
Is your thesis statement specific?
Your thesis statement should be as clear and specific as possible. Normally you will continue to refine your thesis as you revise your argument(s), so your thesis will evolve and gain definition as you obtain a better sense of where your argument is taking you.
Tip: Check your thesis:
- Are there two large statements connected loosely by a coordinating conjunction (i.e. "and," "but," "or," "for," "nor," "so," "yet")?
- Would a subordinating conjunction help (i.e. "through," "although," "because," "since") to signal a relationship between the two sentences?
- Or do the two statements imply a fuzzy unfocused thesis?
- If so, settle on one single focus and then proceed with further development.
Is your thesis statement too general?
Your thesis should be limited to what can be accomplished in the specified number of pages. Shape your topic so that you can get straight to the "meat" of it. Being specific in your paper will be much more successful than writing about general things that do not say much. Don't settle for three pages of just skimming the surface.
The opposite of a focused, narrow, crisp thesis is a broad, sprawling, superficial thesis. Compare this original thesis (too general) with three possible revisions (more focused, each presenting a different approach to the same topic):
- Original thesis:
- There are serious objections to today's horror movies.
- Revised theses:
- Because modern cinematic techniques have allowed filmmakers to get more graphic, horror flicks have desensitized young American viewers to violence.
- The pornographic violence in "bloodbath" slasher movies degrades both men and women.
- Today's slasher movies fail to deliver the emotional catharsis that 1930s horror films did.
Is your thesis statement clear?
Your thesis statement is no exception to your writing: it needs to be as clear as possible. By being as clear as possible in your thesis statement, you will make sure that your reader understands exactly what you mean.
Tip: In order to be as clear as possible in your writing:
- Unless you're writing a technical report, avoid technical language. Always avoid jargon, unless you are confident your audience will be familiar with it.
- Avoid vague words such as "interesting,” "negative," "exciting,” "unusual," and "difficult."
- Avoid abstract words such as "society," “values,” or “culture.”
These words tell the reader next to nothing if you do not carefully explain what you mean by them. Never assume that the meaning of a sentence is obvious. Check to see if you need to define your terms (”socialism," "conventional," "commercialism," "society"), and then decide on the most appropriate place to do so. Do not assume, for example, that you have the same understanding of what “society” means as your reader. To avoid misunderstandings, be as specific as possible.
Compare the original thesis (not specific and clear enough) with the revised version (much more specific and clear):
- Original thesis: Although the timber wolf is a timid and gentle animal, it is being systematically exterminated. [if it's so timid and gentle -- why is it being exterminated?]
- Revised thesis: Although the timber wolf is actually a timid and gentle animal, it is being systematically exterminated because people wrongfully believe it to be a fierce and cold-blooded killer.
Does your thesis include a comment about your position on the issue at hand?
The thesis statement should do more than merely announce the topic; it must reveal what position you will take in relation to that topic, how you plan to analyze/evaluate the subject or the issue. In short, instead of merely stating a general fact or resorting to a simplistic pro/con statement, you must decide what it is you have to say.
- Avoid merely announcing the topic; your original and specific "angle" should be clear. In this way you will tell your reader why your take on the issue matters.
- Original thesis: In this paper, I will discuss the relationship between fairy tales and early childhood.
- Revised thesis: Not just empty stories for kids, fairy tales shed light on the psychology of young children.
- Avoid making universal or pro/con judgments that oversimplify complex issues.
- Original thesis: We must save the whales.
- Revised thesis: Because our planet's health may depend upon biological diversity, we should save the whales.
- When you make a (subjective) judgment call, specify and justify your reasoning. “Just because” is not a good reason for an argument.
- Original thesis: Socialism is the best form of government for Kenya.
- Revised thesis: If the government takes over industry in Kenya, the industry will become more efficient.
- Avoid merely reporting a fact. Say more than what is already proven fact. Go further with your ideas. Otherwise… why would your point matter?
- Original thesis: Hoover's administration was rocked by scandal.
- Revised thesis: The many scandals of Hoover's administration revealed basic problems with the Republican Party's nominating process.
Do not expect to come up with a fully formulated thesis statement before you have finished writing the paper. The thesis will inevitably change as you revise and develop your ideas—and that is ok! Start with a tentative thesis and revise as your paper develops.
Is your thesis statement original?
Avoid, avoid, avoid generic arguments and formula statements. They work well to get a rough draft started, but will easily bore a reader. Keep revising until the thesis reflects your real ideas.
Tip: The point you make in the paper should matter:
- Be prepared to answer “So what?” about your thesis statement.
- Be prepared to explain why the point you are making is worthy of a paper. Why should the reader read it?
Compare the following:
- Original thesis:
- There are advantages and disadvantages to using statistics. (a fill-in-the-blank formula)
- Revised theses:
- Careful manipulation of data allows a researcher to use statistics to support any claim she desires.
- In order to ensure accurate reporting, journalists must understand the real significance of the statistics they report.
- Because advertisers consciously and unconsciously manipulate data, every consumer should learn how to evaluate statistical claims.
Avoid formula and generic words. Search for concrete subjects and active verbs, revising as many "to be" verbs as possible. A few suggestions below show how specific word choice sharpens and clarifies your meaning.
- Original: “Society is...” [who is this "society" and what exactly is it doing?]
- Revised: "Men and women will learn how to...," "writers can generate...," "television addicts may chip away at...," "American educators must decide...," "taxpayers and legislators alike can help fix..."
- Original: "the media"
- Revised: "the new breed of television reporters," "advertisers," "hard-hitting print journalists," "horror flicks," "TV movies of the week," "sitcoms," "national public radio," "Top 40 bop-til-you-drop..."
- Original: "is, are, was, to be" or "to do, to make"
- Revised: any great action verb you can concoct: "to generate," "to demolish," "to batter," "to revolt," "to discover," "to flip," "to signify," "to endure..."
Use your own words in thesis statements; avoid quoting. Crafting an original, insightful, and memorable thesis makes a distinct impression on a reader. You will lose credibility as a writer if you become only a mouthpiece or a copyist; you will gain credibility by grabbing the reader with your own ideas and words.
A well-crafted thesis statement reflects well-crafted ideas. It signals a writer who has intelligence, commitment, and enthusiasm.

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:
Pollution is bad for the environment.
This thesis statement is not debatable. First, the word pollution means that something is bad or negative in some way. Further, 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 good.
Example of a debatable thesis statement:
At least 25 percent of the federal budget should be spent on limiting pollution.
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:
America's anti-pollution efforts should focus on privately owned cars.
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:
Drug use is detrimental to society.
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:
Illegal drug use is detrimental because it encourages gang violence.
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:
At least 25 percent of the federal budget should be spent on helping upgrade business to clean technologies, researching renewable energy sources, and planting more trees in order to control or eliminate pollution.
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:
America's anti-pollution efforts should focus on privately owned cars because it would allow most citizens to contribute to national efforts and care about the outcome.
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, 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:
What some people refer to as global warming is actually nothing more than normal, long-term cycles of climate change.
Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:
The popularity of SUVs in America has caused pollution to increase.
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:
Global warming is the most pressing challenge facing the world today.
Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:
Instead of drilling for oil in Alaska we should be focusing on ways to reduce oil consumption, such as researching renewable energy sources.
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.
