Abstract domain-specific knowledge into domain-agnostic
Abstract domain-specific knowledge into domain-agnostic structure before attempting transfer—concrete practices don't transfer, but structural patterns do.
Why This Is a Principle
Derives from Abstraction Necessarily Discards Information (abstraction discards information), Structural Correspondence in Mental Models (mental models have structural correspondence), and Expertise as Domain-Specific Schema Organization (expertise is domain-specific). This is prescriptive about the mechanism of cross-domain transfer. It's highly actionable and general.
