Principlev1
Active unlearning (deliberate identification and retirement
Active unlearning (deliberate identification and retirement of obsolete knowledge) differs from passive forgetting and requires explicit lifecycle management to execute cleanly.
Why This Is a Principle
Grounds in Belief Perseverance Against Contradictory Evidence (systems maintain beliefs even when basis eliminated), Piagetian Equilibration Through Schema Dynamics (accommodation modifies schemas), and Thoughts and behaviors can be separated from core identity (thoughts can be separated from identity). Hedberg's unlearning requires all three: you must overcome persistence, restructure schemas, and separate knowledge from self. This derives a practice from multiple cognitive constraints.
