Why is hindsight bias a problem?

Hindsight bias is a problem because it causes us to unfairly criticize other people’s decisions and actions. It is easy to see why things unfolded the way they did in the past from the vantage point of the present, when all information is available to us.

Being more informed may cause us to erroneously think that a chain of events was inevitable or predictable. In addition to that, hindsight bias makes us overestimate our own ability to predict the future, which can result in bad or risky decisions.
