Which term refers to the use of personal experience as a form of support in an argument?

The term that refers to the use of personal experience as a form of support in an argument is testimony. Testimonial evidence relies on an individual's personal account or experience to bolster a claim or viewpoint. This method is particularly effective because it allows the audience to connect with the speaker on a personal level, as it reflects real-life situations and emotions. Additionally, personal experiences can provide insight or a unique perspective that statistical or factual evidence may not convey.

Other terms related to argumentation have different meanings: 'evidence' encompasses a broader range of support, including factual data and statistics; 'assertion' refers to a statement or claim without supporting evidence; and 'conclusion' is the outcome of reasoning or argumentation derived from presented evidence. Each of these plays a distinct role in argumentation. However, when it comes to leveraging personal experiences for persuasive purposes, testimonial evidence is the most appropriate choice.
