Hindsight bias

What it is

After learning the outcome, believing we knew it all along and that it was predictable.

Example "It was obvious that the company would fail."

Overconfidence effect bias
Believing the past was predictable makes us overconfident about predicting the future.
Narrative fallacy bias
Once we know how things ended, a neat story explains why, and we feel it was inevitable.
Outcome bias bias
Once we know the outcome we judge the decision by it and believe it should have been foreseen.
Self-serving bias bias
Taking credit for good outcomes as if we had predicted them.
Fallacy of the single cause fallacy
After the fact, the cause seems obvious and singular.
Rosy retrospection bias
Both rewrite the past: hindsight edits our predictions, rosy retrospection edits our feelings.
Black swan events bias
After a rare event, hindsight makes it look predictable.
Falsification of history bias
We rewrite our past judgments to match what happened.
