Record five elements at the moment of every significant decision — before hindsight rewrites it

Why This Is a Rule

Hindsight bias reconstructs decision-making history within hours. Once you know the outcome, your brain rewrites the decision as obvious: "I always knew this would happen" (if it went well) or "I had a bad feeling about this" (if it didn't). Both narratives are confabulations — they feel like memories but are constructed from the outcome backward.

The five-element decision record preserves the actual decision context before hindsight can overwrite it. Decision statement: what exactly you decided. Forces/constraints/emotions: what was pushing and pulling at the choice point — not just the rational factors but the emotional state. Expected consequences with timeline: what you predicted would happen and when. Confidence level 1-10: how sure you were. Review trigger date: when to revisit and evaluate.

This record is the ground truth for future decision review. When you evaluate the decision later (Read the original decision context before evaluating the outcome — sequence prevents hindsight bias), the record provides what you actually thought, felt, and expected — not what hindsight tells you thought, felt, and expected.

When This Fires

• At the moment of commitment to any significant decision
• Writing ADRs (Architecture Decision Records), project commitments, or strategic choices
• Before any decision you'll want to learn from later
• Any commitment where you want future-you to understand past-you's reasoning

Common Failure Mode

Recording only the rational factors and omitting the emotional state. "Forces: budget constraint, team capacity, market timing." But the decision was also influenced by: fatigue from a long meeting, excitement about a new technology, anxiety about a competitor. The emotional forces shape decisions as much as rational ones, and they're the first thing hindsight erases.

The Protocol

At the moment of committing to a significant decision, write five elements: (1) Decision: one sentence stating what you're committing to. (2) Forces: constraints, emotions, pressures active right now — including the uncomfortable ones. (3) Expected consequences + timeline: "I expect [X] to happen by [date]." Be specific. (4) Confidence: 1-10. Be honest, not aspirational. (5) Review date: when you'll revisit this record and compare predictions to outcomes. Total time: 3-5 minutes. The record becomes invaluable when you review it months later with the benefit of outcomes — because the record preserves what you actually knew, not what hindsight tells you you knew.
