A position paper argues for a particular stance on an issue using evidence and facts to support the author's opinion. It aims to convince the audience that the author's position is valid. A strong position paper provides a clear introduction outlining the issue and thesis, body paragraphs with arguments and supporting evidence for each claim, and a conclusion restating the argument and suggesting a course of action. The best way to defend a stance is through factual knowledge, statistical inference, informed opinion, and personal testimony from knowledgeable sources. An effective position paper is well-researched, addresses counterarguments, and is tailored to the target audience.
