Principlev1
Validate important self-schemas using at least three
Validate important self-schemas using at least three independent evidence types: behavioral observation, external feedback, and outcome tracking.
Why This Is a Principle
Derives from Bias Blind Spot Asymmetry (bias blind spot—can't see own biases) and Egocentric Anchoring in Perspective-Taking (egocentric anchoring). The principle prescribes methodological triangulation specifically to overcome self-assessment limitations. Specific enough to be actionable, general enough to be a principle.
