This document outlines five types of evidence: precedent evidence, statistical evidence, testimonial evidence, hearsay evidence, and common knowledge evidence. Precedent evidence establishes expectations for future conduct based on past acts or events, including legal precedent from court rulings and personal precedent from observing others. Statistical evidence includes data from polls, surveys, and experiments but must be carefully analyzed due to potential biases. Testimonial evidence assigns motives and verifies actions through eyewitness accounts, expert opinions, or historiography. Hearsay evidence refers to unverified rumors or gossip. Common knowledge evidence supports non-controversial arguments without needing citations.
