Writing an introduction


 
The introduction to a paper is a very important section, in that it sets the expectations of the reader. While there is no one formula for a good introduction, in general, an introduction to a formal paper of this type should accomplish the following:
  • An introduction should attract the reader's attention. Magazine and newspaper articles often create interest with brief but interesting anecdotes, questions that pique the reader's curiosity, something of personal relevance to the reader, or other apt quotations, provocative questions, or statements. While you shouldn't feel that you have to sensationalize, neither should you assume that the reader is interested in what you have to say by default. Very often just raising the interesting issue that your thesis explores is enough to pull your reader in.

  •  
  • An introduction should tell the reader explicitly what the thesis (the point of the paper) is. Although some forms of discursive writing lead the reader to the thesis only later in the paper or article, in most scholarly writing, readers should have no doubt about what the central point of your paper is at the outset.

  •  
  • An introduction should establish the significance of your point to the reader. You should convince your reader that she or he should care about what you have to say, though attention to relevance and significance is part of constructing a successful thesis.

  •  
  • An introduction should give enough background that the reader can understand the context and hence the significance of the thesis. However, the first paragraph should introduce only as much background as is absolutely necessary for these purposes. Further summary can wait.

  •  
  • An introduction sometimes previews internal points. Writers often (but not always) summarize the ways in which they are going to back up their thesis, so as to prepare the reader and improve the reader's recognition and retention of those points.
A common way to establish significance is through the device Williams calls establishing "shared context." Very often, writers will begin an introduction with a proposition that, while perhaps interesting, is uncontroversial. With the reader's agreement established, the shared context, the writer will then proceed to state a problem that contradicts the proposition. This problem therefore challenges the reader's expectation and creates interest and, we hope, significance. A word such as "however" and "yet" thus often appears towards the middle or end of such introductions.

Here are some things to watch out for in your introduction:

  • Don't start out with a grand generalization. The cliche of the "pyramid form" introduction often leads to uninteresting and unsupportable sentences that might begin with "Throughout history...." Showing the significance of your thesis does not mean that you have to demonstrate its importance in the history of art or tie it to some universal observation.

  •  
  • An introduction is not the place to introduce background or factual information unless necessary to understand the thesis. A common impulse is to start a paper with the story of a person's birth, a summary of an entire story, or with some historical background. However, unless some brief information is necessary to understand the terms within or significance of the thesis, save the background for your following paragraphs.

  •  
  • An introduction should not be too long. An introduction should be a single paragraph, at least for the length of papers for this class. A page-long intro is usually too long -- half a page or less is good. If your opening anecdote is a long one, you don't have to finish it in the introduction -- just introduce enough of it to get the reader's attention and establish the significance of your thesis. You can finish it in the body of the paper. (In fact, such a "teaser" is a common device of newspaper feature writers.)

  •  
  • Don't start your introduction with a dictionary definition. We're not interested in how Webster's defines "Gothic." We are interested in YOUR take on it.

Your second paragraph will often connect the opening anecdote or statement to the rest of the paper, providing a transition from your generalized introduction to your detailed look at your first point. It is also a common technique to refer back to your opening in your conclusion, providing a satisfying closure to the paper.

Although a successful introduction will follow these general guidelines, none of them should imply a rigid formula, nor will I expect one.
