Better Thesis Statements
What is a thesis statement?
A thesis statement is the central claim that the author promises to defend in his or her paper.
Why do I need a thesis statement?
A thesis statement tells the reader where the paper is headed and why s/he should bother going there. It serves to engage the reader’s interest and motivate her or him to read on. From the writer’s perspective, a thesis statement brings her central claim into focus so that it becomes obvious how to build the rest of the paper. A thesis statement, if it is a good one, helps the writer decide what arguments and evidence are necessary to make her point. In a sense, the thesis statement functions as the conscience of a paper; it helps the writer recognize what belongs in the paper and what does not, depending upon the specific promise it makes to the reader.
How do I come up with a thesis statement?
All formal papers and essays have a point. You can have some ideas on a topic, or about an issue, but until you distill what you have drawn a conclusion from your research and reflection and captured in it your thesis statement, your formal writing will lack direction and focus. To arrive at a working thesis statement, try to state out loud or write in a single sentence the most important conclusion you have come to from your research. Here are some examples of simple claims you could make after reading and reflecting in preparation for writing your paper:
- Politicians should use language responsibly if they wish to govern after the campaign.
- The face plays an important role in human communication.
- Migrating Atlantic seabirds need more protection along their migration paths.
Sentences like these, each of which makes a claim, are adequate as “working thesis statements”. As you write, research, arrange, and think through other supporting ideas in your paper, you should be moved to refine your working thesis statement to 1) narrow it, 2) make it more consequential or controversial, or 3) put it in a specific context. With more research and thought, we might revise A.-C. above as follows:
- The speed, reach, and permanence of mass media today can threaten a candidate’s ability to govern once elected.
- Although poets have always noted the role of the face in human communication, facial expression has lately become the subject of intense scientific scrutiny, with the potential for profound social consequences.
- Offshore wind farms, chemical pollution from industrialized livestock facilities, new coastal housing developments pose a triple threat to millions of migrating seabirds who have made their way along the Eastern seaboard of the U.S. for millennia.
These revised thesis statements make specific promises to the reader. Can you predict what kinds of evidence or support a writer might include in his or her essay based on one of these thesis statements?
A good thesis statement gives you room to develop your ideas as you wish, but within the boundaries imposed by your knowledge, time, and page limits. We use the word “narrow” to describe a good thesis statement but we don’t mean “narrow-minded” or “stingy”. Instead, a narrow thesis statement is focused and fits the size and scope of your paper. When everything in your paper is selected to support or explore your thesis statement, then you are enjoying the benefits of a good thesis statement.
Here is a worksheet to help you come up with and refine a good thesis statement.
Thesis Statement Worksheet
What is your topic (the area of study for this paper)?
What background information does the reader need to know before you state your thesis?
What is your working thesis statement?
Test your thesis statement. Does your thesis statement:
- Make a claim that a reader can agree or disagree with?
- Reflect knowledge of the source material?
- Pick out an idea that can be defended in the space allowed?
- Limit the kinds of evidence you can use to defend it?
What evidence, examples, or arguments will you use to support the working thesis?
Now that you have thought ahead about your evidence, can you refine your thesis statement to focus on a particular problem and context? (This is where the originality of your claim comes in.)

trite, not defensible
The last scene in “Midsummer Night’s Dream” showcases Shakespeare’s ability to manipulate subtle linguistic differences among his characters for comic effect.

This essay will show that the North American Free Trade agreement was a disaster.
Neither neo-protectionism nor post-industrial theory explains the downswing of the Canadian furniture industry in 1988-1994. Data on productivity and profits, however, can be closely correlated with provisions of the North American Free Trade Agreement that took effect in the same period.

Myths about thesis statements
- A thesis statement is the topic of a paper or what the paper is ‘about.’
If a reader knows that your paper is about migrating birds, she still doesn’t know what your point is. Only a thesis statement can tell the reader that. A topic merely names the field or subject area of your paper; it doesn’t propose anything. Topics are identified in other sentences that give background information that usually lead up to the thesis statement. Compare the topic sentence below with the thesis statement that follows it:
Topic sentence: There are few people totally unfamiliar with bingo—that game of chance in which numbers, called at random, are plotted on cards to form patterns and to win prizes.
Thesis statement: In order to understand bingo as a cultural phenomenon it should be studied not as a cultural ‘thing’ but as behavior compatible with a patterned way of life.
- Some writers put their thesis statement at the end of their paper.
This myth confuses the concluding section of a paper with the intellectual conclusion a writer must reach in order to begin writing a paper in earnest. Since a good thesis statement is the result of research, reflection, and, sometimes, a draft or two of the entire paper, it might seem that it ought to come at the end of one’s essay. But, in academic writing, what is the outcome of thinking and writing for the writer is best presented as the starting point for the reader. Many writers restate their thesis statement/hypothesis in the concluding section of their papers but few choose to delay revealing their central claim until after they have argued in favor of it
- There are strict rules about the form of a thesis statement.
You can learn to write better thesis statements by practicing with specific forms, e.g. one where a premise (“If term limits were adopted in today…”) precedes a conclusion (“we would lose valuable legislative experience.”). Yet if you grasp the function of a thesis statement, many forms are possible. It may take the form of a supported assertion as in “I agree with the author because…” or it can direct the reader’s attention to a scientific or philosophical issue as in “Gardner’s theory of Multiple Intelligences has applications in the kindergarten classroom for..” or “The relationship between body and soul remains a central issue in…” Short pithy thesis statements are also possible as in “Television kills”—a claim, to be sure, but one which needs elaboration in nearby sentences to correctly direct the reader’s focus.
- A thesis statement is just your opinion.
While a thesis statement does present the reader with a claim, it should go well beyond a simple assertion that anyone can make without detailed information about the topic. Statements such as People are too lazy to solve the environmental crisis we face or Today’s educators need to know how to deal with students who don’t speak English don’t convey that the writer has researched his topic and come away with something new or non-obvious to say. A thesis statement offers an informed opinion that the writer is prepared to support with facts, arguments, analysis, and research-based evidence. It might be helpful to remember that a thesis statement takes a ‘point of view’ which the paper develops so that the reader can decide for himself on the issue.
