Hindsight Bias
The tendency, once an outcome is known, to believe that it was more predictable than it was, and to remember having expected it.
- Ex: After a team loses in the playoffs, a fan says he knew they would lose, though he had bet on them the week before.
- Ex: A student who learns that a classmate dropped the course says it was obvious from the first week, though she had not thought about it before.
- Ex: After a stock falls, a man says the warning signs were there, though he had not sold it.
