What is proactive schema review?

Proactive schema review is a concept in personal epistemology: Do not wait for failure to update schemas — regularly review and refine them.

Example: An engineering manager reviews her leadership schema quarterly, not because anything went wrong, but because she's learned from three months of new experience. She asks: What assumptions am I making about how my team works? Which ones have I actually tested? She finds she's still operating on 'senior engineers don't need check-ins' — a belief inherited from her first manager. She updates it before it costs her a resignation.

This concept is part of Phase 16 (Schema Evolution) in the How to Think curriculum, which builds the epistemic infrastructure for schema evolution.
