The overall claim you developed as you built your argument provides the foundation for your thesis statement — a brief statement that conveys the main point you want to make about your issue. In an argumentative essay, a thesis statement should be debatable, plausible, and clear.
An effective thesis statement will shape your readers’ understanding of the issue, directing their attention to particular aspects of the issue and away from others. Consider, for example, the following thesis statements about athletes’ use of performance-enhancing drugs.
Thesis statement 1: If for no other reason, athletes should avoid the use of performance-enhancing drugs to safeguard their personal health.
Thesis statement 2: To eliminate the use of performance-enhancing drugs, athletes themselves must take the lead in policing their sports.
Thesis statement 3: National and international governing bodies for sports should engage in a coordinated effort to educate aspiring athletes about ethics and sportsmanship.

These thesis statements would lead to significantly different argumentative essays. The first thesis statement directs readers’ attention to the health consequences for athletes who use performance-enhancing drugs. The second suggests that athletes themselves should take charge of efforts to eradicate this form of cheating. The third thesis statement focuses attention on the contributions that might be made by what are essentially large corporate and government agencies. Each thesis statement is plausible and debatable, and each one tells readers what they should believe or act on. Yet each leads the reader to view the issue in a significantly different way.
