A strong thesis statement is key to writing a persuasive essay. The thesis statement presents your topic to the reader, provides your opinion on that topic and summarizes the argument you’ll make in the paper by offering evidence for your opinion. A good thesis statement should capture all of these essential details in just one or two sentences. The thesis statement generally appears after a brief introduction of your topic, often as the last sentence of your first paragraph. The following information will help you write a thesis statement for a persuasive essay.
Express an Opinion
When you sit down to write a thesis statement, make sure that you have a clear opinion about your topic. That’s because a thesis statement must include a claim that others might dispute. Your thesis summarizes the argument you’ll be making in your paper, so you want to make sure that your point of view is clear and debatable. An easy way to test your thesis is to ask yourself whether your reader could challenge or oppose your thesis statement. If your thesis simply states facts that someone couldn’t disagree with, you may simply be summarizing an issue rather than presenting a clear point of view.
A strong thesis statement is focused and specific. The reader should know exactly what you’re going to argue and why. “Online education is a great choice for students” is a weak thesis because it’s not specific or focused enough. A stronger thesis would be, “Online classes are a better choice than traditional classroom learning because they’re more flexible for students and teachers, they're less expensive and they let students works at their own pace.”
It’s important to include evidence in your thesis statement to help support your opinion. Doing so tells readers that you understand the topic and have performed some research, which gives you more credibility as a persuasive writer. It also creates a road map for readers, so they know what evidence you’ll discuss with more detail in the paper. For example, if your thesis is, “Companies should not test their products on animals because it’s inhumane and unethical, and it doesn’t always lead to accurate results,” the reader knows right away what your opinion is and what evidence you'll provide to support that opinion in your paper.
Pass the "How and Why" Test
Your thesis statement should answer one or both of two key questions: “how” and “why.” For example, if you think that online learning is more effective for students than traditional instruction, then your thesis should tell readers how or why it’s more effective. If a reader can't determine the "how" or "why" from your thesis statement, your thesis might be too open-ended, and you may need to revise it to be more specific or to clarify your point of view.
