Schema validation
the systematic practice of testing beliefs against evidence, welcoming disconfirmation, and refusing to protect comfortable models from uncomfortable data
Why This Is a Definition
This definition precisely establishes schema validation as a specific practice rather than a general concept. It identifies the key operational elements: systematic testing, evidence confrontation, and refusal to protect models. The definition distinguishes it from mere belief testing by emphasizing the specific discipline of welcoming disconfirmation and refusing protection of comfortable models, which is central to the lesson's emphasis on epistemic honesty.
