What is reality testing psychology?

Reality testing psychology is a concept in personal epistemology: The most reliable way to test a schema is to act on it and observe the results.

Example: You believe that your team performs better with less oversight — that autonomy drives motivation. Instead of debating this internally forever, you run a two-week experiment: remove your daily check-ins for one project. You track output, morale, and blockers. After fourteen days, the data either supports, refines, or falsifies your schema. The belief is no longer theoretical. It has been tested against reality, and reality answered.

This concept is part of Phase 15 (Schema Validation) in the How to Think curriculum, which builds the epistemic infrastructure for schema validation.
