Overconfidence is the cognitive bias in which a person's subjective confidence in their judgments, abilities, or predictions systematically exceeds their objective accuracy. The parameter that defines it is the confidence-accuracy gap — the measurable difference between how certain someone claims to be and how often they are correct. It persists through social reinforcement (where confidence is mistaken for competence), through motivational mechanisms (self-enhancement biases that promote action), and through disciplinary frameworks in psychology and behavioral economics that study, measure, and model its patterns across domains.

Overconfidence is the tendency to overestimate abilities/outcomes. Removal test: remove expectation and overconfidence stops operating — there is nothing to be 'over' about if no expectations can be formed. Overconfidence is an inflated-expectations pattern; it needs expectation as its substrate. Test: which came first? expectation (0.08) predates overconfidence (0.58).
