The Summary Introduction
Summary Introduction Example:
There is considerable controversy about whether small dogs are implicated in the squirrel controversy, but a comparison between squirrels and small dogs suggests that they are. Squirrels and small dogs are both about the same size. Squirrels and small dogs all have "Napoleonic" complexes. This complex causes them to hate larger dogs, and try to attack them at every opportunity. Although squirrels do not yip like small dogs, they do make sounds that are equally irritating. It is, therefore, clear that small dogs are conspiring with squirrels to get the red ball.
In my experience, students are very good at the summary introduction: the introduction that tells 'em what you're gonna tell 'em. It summarizes the whole argument of the paper. While this kind of introduction has its uses, I cannot figure out why teachers put so much emphasis on it; it's just one of many ways to begin a paper, and generally not the most effective.
Students who are good at this kind of introduction usually write them last. Lots of students try to write them first, but it often doesn't work for one of two reasons. First, most of us figure out what we think by trying to write it down, so trying to write a summary introduction first is trying to summarize an argument you haven't yet figured out. You can't summarize it because you don't know what it is. That first shot at a summary introduction is, therefore, often a summary of a much more simplistic argument than a later version would be. The second problem is that it tends to be very unpersuasive to an informed and intelligent opposition audience. They are alienated by the list of arguments, more often than not.
Having said what's wrong with a summary introduction, I'll say what's good about it. It's a great kind of introduction for circumstances in which the reader is not open to persuasion—an essay exam, for instance, in which the reader just wants to see that you've given the correct answer. (My personal suspicion is that teachers who teach this kind of introduction exclusively treat all student writing as exam answers.) In such writing circumstances (e.g., exams), the summary introduction can serve as a blueprint. Just as a blueprint keeps the builder from doing something unplanned and therefore potentially dangerous, so a summary introduction will keep you to the plan that you've already figured out. Also, there are circumstances in which you are expected to summarize your argument--in an abstract or precis, for instance--so knowing how to write a brief summary of a complicated argument is a good skill to develop. Finally, if you're good at writing summary introductions and bad at conclusions, one solution is to take your summary introduction and make it your conclusion, then write a different kind of introduction.
