The Learning Killer

Hindsight bias is dangerous because it quietly destroys the ability to learn. If every outcome looks "obvious" in retrospect, there is nothing left to learn from it.

In court, jurors often judge defendants by outcomes no one could have predicted. A company that made a reasonable decision which then turned out badly can look negligent simply because the jury already knows it ended badly. The bad result feels like proof the danger was obvious all along, even when, beforehand, it was not.
