The certainty you feel about what you should have seen is not proof you missed something obvious - it is

proof your memory has already rewritten the decision to match the ending you now know. Part of The Bias

Files, Simon Blackwood's insightful book explores the mechanism that makes past outcomes feel inevitable,

erasing the uncertainty that shaped every choice at the time it was made.

When an outcome becomes known, memory stops being a neutral record and becomes a reconstruction engine,

quietly revising stored decisions, predictions, and doubts to align with information unavailable when you

needed it. I Knew It All Along is not a memory-training program, a decision framework, or a guide to

preventing mistakes. Instead, it exposes the cognitive machinery that makes hindsight feel like foresight,

showing how certainty about the past distorts judgment about the present.

Through cases drawn from markets, medicine, intelligence analysis, and relationships, you will explore the

hidden mechanics of hindsight bias:

- The Working Draft: Why memory reconstructs decisions each time you recall them, incorporating

everything learned since - including the outcome that was unknowable at the time.

- The Sincere Rewrite: How a manager writing an unfair performance review genuinely believed warning

signs had been clear, not from dishonesty but because their mind had forgotten what uncertainty felt like.

- The Trade Everyone Saw Coming: Why the 2008 crisis looks foreseeable now, while the actual

pre-crisis record - forecaster surveys, policy transcripts, economist writing - shows no such consensus.
