Decision OS / Journal
Write the decision before hindsight edits the evidence.
Capture frame, options, values, assumptions, confidence, risks, and next step while the uncertainty is still honest.
Case notes
Decision Journal makes the decision process visible before the outcome arrives.
Outcomes rewrite memory. If a decision works, we over-credit the process. If it fails, we pretend the warning signs were obvious. A decision journal protects learning from hindsight bias.
The journal should be short enough to use before real decisions. It is not a diary of feelings; it is a timestamped process record.
01
Record before the outcome.
The value is preserving what was known then.
02
Include confidence.
Confidence lets future review compare belief with reality.
03
Keep it short.
A journal nobody uses is a beautiful failure.
Common problems and experiments
Make the next process move small enough to test this week.
I do not have time to journal.
Experiment
Use seven lines: decision, frame, options, values, assumptions, risks, next step.
What to watch
Short records beat perfect records.
I only journal big decisions.
Experiment
Journal one medium decision weekly to build the habit.
What to watch
Judgment improves through repetitions.
I write vague entries.
Experiment
Add confidence percentage and a review date.
What to watch
Future learning needs a timestamp.
Prompt to try
Keep one decision sentence visible.
What do I believe right now, before the outcome teaches me what to pretend I knew?

Biases and hindsight
Heuristic shortcuts and outcome interpretation can distort retrospective judgment.

Decision journals are reflection tools, not legal, medical, financial, or professional records.
