Hindsight Bias
Believing past events were obviously predictable once we know how they ended.
"We always knew it would fail — narrated entirely in past tense."
What is Hindsight Bias? Believing past events were obviously predictable once we know how they ended. Learning gets replaced by a clean story everyone now believes they predicted.
Post-mortems that distort accountability into folklore.
Learning gets replaced by a clean story everyone now believes they predicted.
Treating AI breakthroughs as obvious in retrospect, foresight in prospect.
Time-stamp predictions in writing before outcomes are known.

When you encounter Hindsight Bias, your hippocampus stitches the experience into a story — and that story will shape what you do next time more than the facts will.
Episodic memory, narrative formation, spatial mapping, learning from experience. Your memory of what happened is a reconstruction, not a recording. Every retelling edits the file.
