What is knowledge consolidation?

Knowledge consolidation is a concept in personal epistemology: When you connect your schemas you discover that many are variations of the same underlying idea.

Example: You maintain separate mental models for 'sunk cost fallacy' in financial decisions, 'commitment escalation' in project management, and 'relationship inertia' in personal life. When you finally map all three side by side, you realize they are the same schema: continuing to invest in something because of past investment rather than future value. Three labels. One structure. The moment you see the isomorphism, your entire schema library contracts — and your ability to apply that insight across domains expands.

This concept is part of Phase 20 (Schema Integration) in the How to Think curriculum, which builds the epistemic infrastructure for schema integration.
