The Concept
Most people treat decisions as finished once they act. But the decision process has one more critical step: going back to examine what happened and why. Without this review, you are doomed to repeat mistakes and to draw the wrong lessons from your successes.
The key insight is that outcomes are a poor guide to decision quality. A good decision can produce a bad outcome (you made the right call, but unlikely events intervened), and a bad decision can produce a good outcome (you got lucky). If you only judge decisions by their results, you will reinforce bad habits when they happen to work and abandon good ones when they happen not to.
Effective review separates process from outcome. Did you define the problem clearly? Did you explore enough options? Were your evaluation criteria sound? Did you execute with commitment? Answering these questions honestly -- regardless of whether the outcome was favorable -- is what drives genuine improvement. A decision journal is one of the most powerful tools for this, because it captures your reasoning at the time of the decision, before outcome bias can rewrite your memory.
Recognition Patterns
- You celebrate wins without examining whether the process was actually sound, or whether you simply got lucky.
- You blame bad outcomes entirely on external factors without asking whether your process had gaps.
- You have no record of why you made past decisions, making it impossible to learn from them systematically.
- You keep making the same type of mistake -- in hiring, in project estimation, in relationship decisions -- without identifying the pattern.
- You feel defensive when someone questions a past decision, suggesting ego is interfering with honest review.
Actionable Takeaways
- Keep a decision journal. Before acting, write down what you decided, why, what you expect to happen, and how confident you are. Review it regularly.
- Schedule a review at a set interval after each major decision (30, 60, or 90 days). Do not wait for the outcome to feel "final" -- the sooner you reflect, the sharper your memory.
- When reviewing, ask two separate questions: "Was the outcome good or bad?" and "Was the process good or bad?" These are independent dimensions.
- Look for patterns across decisions, not just individual cases. One bad outcome might be noise; five bad outcomes in similar situations reveal a flaw in your approach.
- Share your reviews with a trusted peer or mentor. Outside perspectives catch blind spots that self-reflection cannot.
Connect the Dots
The review step completes the cycle by feeding lessons back into how you define future problems. Each decision you review sharpens your pattern recognition, making you faster and more accurate at diagnosing the next situation.
This step is deeply connected to self-mastery, particularly self-accountability. Honest review requires the willingness to admit mistakes and the discipline to follow through on lessons learned, even when it is uncomfortable.
The practice of keeping a decision journal is also a natural safeguard against outcome bias and hindsight bias. When your original reasoning is written down, you cannot unconsciously rewrite history to make yourself look more prescient than you were.
