Types of Positions
Position statements fall into categories and those categories suggest how a claim should be argued. Your position, knowledge and authority on the subject will help you decide which category best suits the argument's purpose.
Before selecting one, however, consider your audience. Which side are they likely to be on or will they be split down the middle? How informed are they? Where lays the largest difference of opinion? Is the issue emotionally charged? If so, how will the audience react?
The answers you come up with will help determine what type of position will be most effective and what to include in the introduction, the type of evidence to be presented and how the presentation should be organized.
