This document discusses reasons and identifying reasons when evaluating opinions and arguments. It defines reasons as the rationale or justifications used to support a conclusion. Identifying an author's reasons is important for a fair evaluation of their opinion. Focusing on reasons requires remaining open to opposing views and examining one's own opinions. When analyzing an argument, one should determine the intent, quality of evidence, and relationship between the conclusion and reasons provided. Various types of evidence like facts, statistics, and expert testimony can be used as reasons. Weak reasons undermine the overall reasoning.
