How do I practice post-decision review?

The most direct way to practice post-decision review is through a focused exercise: Pick one significant decision you made in the last 90 days where you now know the outcome. Write down: (1) what you decided and why, (2) what actually happened, (3) whether the outcome was due to your process or to factors you could not have known. Separate the verdict on your process from the verdict on the result. If the process was good but the outcome was bad, identify what new information would have changed your thinking — and add it to your decision framework for next time.

Common pitfall: Conflating outcome quality with decision quality. When things go well, you credit your brilliance. When things go badly, you blame your judgment. This makes your review useless — you learn nothing about your actual decision process because you are only responding to results. The deeper failure is skipping reviews entirely for decisions that worked out, because 'good outcomes' feel like they need no examination. Some of your worst decision habits are hiding behind lucky results.

This practice connects to Phase 23 (Decision Frameworks) — building it as a repeatable habit compounds over time.
