Decision Log Entry
Records a decision with what you believed at the time and what would change your mind, so it is not relitigated every quarter.

Running it, start to finish
- Write the entry the day the decision is made.
- State honestly what you did not know.
- Put the review date in the calendar.
What you get back
The output this produces, every time.
- Captures what was known at the time, which memory reconstructs around the outcome and cannot be recovered later.
- Records what would change your mind before you are invested in the choice.
- Stays short enough that keeping the log does not become the reason to stop keeping it.
Getting better results
Where this usually goes wrong, and how to avoid it.
- Write it the same day. Section 2 degrades within a week. What you did not know at the time is the first thing hindsight edits.
- Steelman the rejected options. A dismissive line invites the whole debate again from someone who assumes you did not consider them.
- Keep it under 400 words. A log that takes an hour per entry stops being written by month two, and a partial log is worse than none.
