Question
What is decision journal template?
Quick Answer
Record decisions, their reasoning, and their outcomes to improve future decision-making.
Decision journal template is a concept in personal epistemology: Record decisions, their reasoning, and their outcomes to improve future decision-making.
Example: You decide to hire a contractor instead of a full-time employee. Before you send the offer, you open your decision journal and write: the decision, today's date, the three reasons driving it, the outcome you expect in six months, and your current confidence level (70%). Six months later, you revisit the entry. The contractor left after four months. Was the reasoning flawed, or did an unforeseeable event intervene? Without the journal entry, you'd rewrite history — convinced you 'always had doubts.' With it, you can see exactly what you believed and why.
This concept is part of Phase 23 (Decision Frameworks) in the How to Think curriculum, which builds the epistemic infrastructure for decision frameworks.
