About this listen

Mick West examines the history and criticism of the “extraordinary claims require extraordinary evidence” maxim, showing how its vagueness invites accusations of unfairness from UFOlogists and parapsychologists. He argues that skeptics should move beyond catchphrases and instead apply Hume’s principle of proportioning belief to evidence, stressing that claims violating established science demand especially strong proof.
