Hindsight Bias
Also called: knew it all along effect, creeping determinism
Hindsight bias is the feeling that an outcome was predictable once you know it happened. It corrupts learning in two directions: it makes past crashes look obvious, which breeds overconfidence about spotting the next one, and it makes good decisions with bad outcomes look foolish. A contemporaneous written record is the only reliable defence, which is the real argument for a decision journal.
