The tendency to see past events as being predictable.Hindsight is the inclination to see events that have occurred as being more predictable than they, in fact, were before they took place. The event that actually happened is more prominent in our mind than the possible outcomes that didn't occur. This bias has been demonstrated experimentally in a variety of settings, including politics, games and medicine. Also called "The I-Knew-It-All-Along Effect."
