The Calibrated Mind

Hold every judgment at its right strength under uncertainty

Stop confusing a feeling of certainty with a measurement of it

You cannot tell the difference between a judgment you should bet on and one you should question, because your confidence feels like a feeling rather than a measurement. The Calibrated Mind introduces the CALIBRATE system: nine skills that let you assess your own certainty, update it as evidence arrives, and act decisively without pretending the uncertainty is gone. The system Superforecasting proves is possible and Thinking, Fast and Slow proves is necessary.

• The CALIBRATE system: nine operational skills you run on any judgment
• Bayesian reasoning in plain language, with no formulas required
• Decision hygiene: pre-mortems, reference classes, prediction journals
• Calibration training exercises and worksheets in every chapter
• A repeatable protocol for daily operations through to strategic bets
