Run a weekly decision review session
Set aside 20 minutes each week to score past decisions and extract one lesson.
Key takeaways
- What it is: Set aside 20 minutes each week to score past decisions and extract one lesson.
- Why it works: Decisions and their outcomes are separated in time, which means feedback is only useful if you create a deliberate moment to receive it. Without a regular review ritual, entries in a decision journal never get closed, outcomes never get compared to predictions, and the feedback loop — the only reason to keep the journal — never closes. A weekly cadence is frequent enough to keep the reasoning fresh and infrequent enough not to feel onerous.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Writing journal entries but never reviewing them, which preserves the record without extracting any feedback — the equivalent of a fitness tracker you never look at.
Why it works
Decisions and their outcomes are separated in time, which means feedback is only useful if you create a deliberate moment to receive it. Without a regular review ritual, entries in a decision journal never get closed, outcomes never get compared to predictions, and the feedback loop — the only reason to keep the journal — never closes. A weekly cadence is frequent enough to keep the reasoning fresh and infrequent enough not to feel onerous.
How to do it
- 1Book a recurring 20-minute weekly slot, perhaps Friday afternoon.
- 2Open any entries that have reached their expected outcome window.
- 3Score each on process and outcome (separately), note what surprised you.
- 4Write one sentence of lesson and one sentence of application to an upcoming decision.
What the evidence says
ObservationalStructured review improves goal-attainment and learning from experience — a consistent finding in goal-setting research. The specific "weekly decision review" cadence is a practitioner convention, not a tested schedule, but the review-beats-no-review principle is solid.
Honest caveat: The benefit of review in principle is well supported; the optimal cadence for decision review specifically has not been studied. Weekly is a reasonable default, not a magic number.
Common mistake
Writing journal entries but never reviewing them, which preserves the record without extracting any feedback — the equivalent of a fitness tracker you never look at.
IX Coach schedules and triggers the weekly review, pulls relevant past entries for you to score, and builds a dashboard of your decision patterns across time — making the feedback loop automatic rather than optional.
