Ikwipedia:Evidence
The investigation of paradigm-shifting phenomena involving other intelligent entities necessarily must rely on non-empirical evidence. That empirical evidence is infrequent in such investigations cases is a reflection of the nature of the subjects themselves. Paranormal entities, conspiracy actors, and other elusive beings — if they exist — may actively resist empirical scrutiny, understanding the significance of reproducible evidence in a manner similar to the investigators themselves. Evidence affirmatively includes testimony.
