Decisions and outcomes are different
The quality of a decision must be examined using what was knowable at the time, not only what happened afterward.
Also known as Decision quality is not outcome quality
A reasonable decision can produce an undesirable result. A careless decision can produce a favourable one. Outcomes contain information, but they are not a complete verdict on the reasoning that preceded them.
To examine decision quality, ask:
- What information was available at the time?
- Which assumptions were visible?
- What alternatives were considered?
- Was the risk proportionate to the possible benefit?
- What conditions would have triggered reconsideration?
To examine an outcome, ask what came from the choice, what came from execution, and what came from timing, chance, or external conditions.
Decision journaling helps preserve this distinction. Without a record, people often rewrite their earlier beliefs after seeing the result.

Why we hold this for now.
Evidence strengthens a position without making it universal. This records the current basis, limits, possibilities, and conditions for revision.

Counterpoints
No explicit counterpoint is attached yet. Absence of a counterpoint is not evidence of consensus.
BOUNDARY CONDITIONS
- Outcomes remain relevant evidence for updating future beliefs, models, and execution choices.
- A decision can be reasonable given prior information while still reflecting avoidable process failures not captured by outcome-bias research.
- Decision quality should not be evaluated without considering information quality, incentives, execution, and who carried the risk.
POSSIBILITIES
- Pre-outcome records may make retrospective reviews more calibrated by preserving what was actually believed before results arrived.
- Replicated evidence that outcome knowledge does not systematically influence retrospective judgments of decision quality.
- A stronger model showing that outcome-only evaluation predicts future decision quality better than process-aware evaluation across relevant domains.
