Write it down before you know.
Hindsight rewrites memory. A decision journal records your reasoning at the time, so you can learn from it honestly later.
The decision
What & The Options
- What we chose
- What we didn't, and why
The expectation
What We Think Will Happen
- Expected outcome, stated plainly
- How we'll know
The confidence
How Sure We Are
- A rough %, not false certainty
- The key assumption we're betting on
The review
When We Look Back
- A date in the calendar
- Was it the decision or the luck?
Judge the decision, not just the outcome.
