Principlev1
Document disconfirmations more carefully than confirmations,
Document disconfirmations more carefully than confirmations, because confirmations are naturally retained in memory while disconfirming evidence is filtered out.
Why This Is a Principle
Derives from Belief Perseverance Against Contradictory Evidence (belief perseverance) and Automatic Pattern Perception (confirmation bias filters contradictory evidence). The principle prescribes asymmetric documentation effort to counteract memory's asymmetric filtering. Actionable and well-grounded.
