Write the decision before hindsight edits the evidence.
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.
Record before the outcome.
The value is preserving what was known then.
Include confidence.
Confidence lets future review compare belief with reality.
Keep it short.
A journal nobody uses is a beautiful failure.
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.
Keep one decision sentence visible.
What do I believe right now, before the outcome teaches me what to pretend I knew?
The decision card template

Biases and hindsight
Heuristic shortcuts and outcome interpretation can distort retrospective judgment.
Open sourceImplementation intentions
Specific next steps improve follow-through after the journal is written.
Open sourceEducation-only scope
Decision journals are reflection tools, not legal, medical, financial, or professional records.
