Every instance of acting despite fear provides calibration
Every instance of acting despite fear provides calibration data that fear's predicted catastrophe rarely materializes fully, accumulating evidence that changes your relationship to fear from authority with veto power to familiar threshold companion.
Why This Is a Principle
Grounds to Domain-Specific Calibration Development (calibration from feedback loops), Learning occurs when outcomes differ from predictions, (learning from prediction error), Self-efficacy beliefs are formed primarily through mastery (self-efficacy from mastery), and Expert performance in complex domains requires deliberate (deliberate practice requirements). This principle explains the long-term developmental arc of courage as a practice rather than a trait, prescribing repeated action as the calibration mechanism.
