Think of yourself as an associate of a jury, listening to an attorney that is presenting an opening argument. You need to know very soon whether or not the lawyer believes the accused to be guilty or perhaps not guilty, and how the lawyer intends to convince you. Readers of academic essays are just like jury members: they want to know what the essay argues as well as how the writer plans to make the argument before they have read too far. After reading your thesis statement, your reader should think, „This essay is going to try to convince me of something. I’m not convinced yet, but I am interested to see how I may be.”
An effective thesis cannot be answered with a simple „yes” or „no.” A thesis is not an interest; neither is it a known fact; neither is it an opinion. „good reasons for the fall of communism” is a topic. „Communism collapsed in Eastern Europe” is an undeniable fact known by educated people. „The fall of communism is the best thing that ever happened in Europe” is an impression. (Superlatives like right here „the best” almost always result in trouble. It’s impossible to weigh every „thing” that ever happened in Europe. And what about the fall of Hitler? Could not that be „the thing that is best”?)
A thesis that is good two parts. It should tell what you want to argue, plus it should „telegraph” the manner in which you plan to argue—that is, what support that is particular your claim is certainly going where in your essay.
Steps in Constructing a Thesis
First, analyze your sources that are primary. Search for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications associated with the author’s argument? Figuring out the why to one or more of these questions, or even related questions, will put you on the road to developing a thesis that is working. (Without the why, you almost certainly have only come up with an observation—that you can find, by way of example, many different metaphors in such-and-such a poem—which just isn’t a thesis.)
