The article suggests that when we learn the outcome of an event, our memory of our initial judgment tends to shift closer to the actual outcome. This is called hindsight bias. The researchers propose a model where our knowledge is updated after feedback, leading to a reconstruction of our original judgment. They found that our knowledge after feedback is influenced by the feedback itself, and that recalling our initial knowledge before feedback can reduce hindsight bias. The model explains why hindsight bias occurs in most cases and suggests that it is a by-product of our brain's way of updating knowledge after receiving feedback.
