A position paper presents an author's position on a debatable issue and defends it using evidence. It is an academic writing type used in academics, law, and politics. A position paper is typically 1-1.5 pages long and contains factual arguments to support the main claim or position statement, while also addressing potential weaknesses. When writing a position paper, the author should choose a clear position, address all sides of the issue, support their argument with facts, and convince the audience that their position is valid and worthy of consideration. Factual statements can be proven true using evidence, while opinions express beliefs that cannot be objectively proven.
