  • "According to critics of paranormal beliefs, postdiction (or post-shadowing, retroactive clairvoyance, or prediction after the fact) is an effect of hindsight bias that explains claimed predictions of significant events, such as plane crashes and natural disasters. In religious contexts it is frequently referred to by the Latin term vaticinium ex eventu, or prophesy after the event. Through this term, critics claim that many biblical prophecies (and similar prophecies in other religions) that may appear to have come true were in fact written after the events supposedly predicted, or that their text or interpretation were modified after the event to fit the facts as they occurred."
