How do I practice calibration training?

The most direct way to practice calibration training is through a focused exercise: Start a calibration journal. For seven consecutive days, make five predictions each day about events whose outcomes you will know within 48 hours — project deadlines, meeting outcomes, whether someone will respond to your email, weather, traffic, anything with a verifiable result. For each prediction, assign a confidence level: 50%, 60%, 70%, 80%, 90%, or 95%. At the end of the week you will have 35 predictions. Tally your results by confidence bucket. If your 80% predictions came true 80% of the time, you are well calibrated at that level. If they came true only 55% of the time, you have discovered an overconfidence gap that introspection alone would never have revealed. This is not an exercise in humility. It is an exercise in measurement.

Common pitfall: Substituting introspection for feedback. The most common failure is believing you can calibrate by thinking harder about your thinking. You cannot. Introspection without external reference data is a closed loop — the same biased instrument evaluating its own biased outputs. A second failure mode is collecting feedback but not structuring it for comparison. Knowing that a prediction was wrong is less useful than knowing that your 80% predictions fail 40% of the time. The pattern, not the individual data point, is what drives recalibration.

This practice connects to Phase 8 (Perceptual Calibration) — building it as a repeatable habit compounds over time.
