Decision Review

How to Review a Decision Without Hindsight Bias

A good decision review separates the quality of the process from the luck of the outcome. That distinction is what lets you improve instead of just blame yourself.

Hindsight bias makes outcomes feel obvious after they happen. A written decision record gives you something better than memory: it shows what you believed before the result arrived.

The 7-day review

The first review should be practical. Ask what happened after the first action, what was harder than expected, and whether you should keep, change, or stop. At seven days, you are reviewing friction more than final outcome.

The 30-day review

The second review should compare expected and actual outcomes. Do not rewrite your original reasoning. Add the result, the deviation, and the correction.

Questions to ask

Review rule: do not overwrite the original decision. Add result, deviation, and correction below it.

Make the next adjustment small

Reviews fail when they become moral verdicts. Keep the next adjustment operational: change the checklist, add a warning signal, ask one person earlier, set a tighter scope, or define a stop condition before committing.
