Definition
This principle separates decision quality from results.
A good decision can lead to a bad result.
A bad decision can lead to a good result.
Outcomes alone do not measure decision quality.
Why This Matters Under Uncertainty
Financial decisions are made with incomplete information.
Future conditions are unknown at the time of choice.
Results are influenced by external variables outside direct control.
If decisions are judged only by outcomes, randomness is mistaken for skill or error.
What People Commonly Get Wrong
• Assuming profit means the decision was correct
• Assuming loss means the decision was flawed
• Changing strategy after short-term pain
• Copying decisions that recently worked for others
• Optimizing based only on recent performance
What This Principle Is Not
• It is not ignoring outcomes
• It is not dismissing feedback
• It is not defending poor reasoning
• It is not encouraging blind persistence
Structural Limits
This principle does not remove uncertainty.
It does not guarantee better financial results.
It does not prevent losses.
It only improves how decisions are evaluated.
