An overconfidence-bias is a specific kind of cognitive bias where the subject systematically overestimates their own abilities, knowledge, performance, or the favorability of outcomes compared to objective measures. Parameters: (1) the overestimation must be quantifiable against an independent benchmark; (2) it operates across diverse domains of competence; (3) it persists despite contradictory feedback or evidence. The construct persists through psychological nomenclature (it is named, measured, and studied), in decision-science protocols (calibration exercises and debiasing techniques), and in everyday language (the word itself trains speakers to detect it). [formal: overconfidentia | substrate: mind | horizon: a life | explicit: yes | epoch: 0.01]

Overconfidence-bias operates through the mechanism of distorted self-evaluation. The bias consists in systematically overestimating one's own abilities or knowledge — this requires self-assessment as the mechanism being distorted. Remove self-assessment and the bias has no operation: there is no evaluating self to be overconfident about.
