You Are Not So Smart: Chapter 4 Hindsight Bias, What is it?

Hindsight bias is the cognitive tendency for people to perceive events that have already occurred as having been more predictable than they actually were before the events took place, causing individuals to reconstruct their past beliefs and memories to create the illusion that they knew or believed something all along, even when they did not; this bias affects how we remember our own predictions and judgments, making us appear more prescient than we actually were, and it can distort our memories of what we knew and believed before events occurred.
