Cognitive Bias
A cognitive bias is a systematic tendency in human judgment that departs from an explicit normative standard such as formal logic or expected utility theory.
Overview
Experimental research initiated by Amos Tversky and Daniel Kahneman identified regular departures from normative rational choice axioms, characterizing recurring patterns such as anchoring, availability, and framing effects. Rather than attributing deviations solely to random calculation error, research programs evaluate whether these tendencies arise from simplifying heuristics, bounded information capacity, or adaptive mechanisms tailored to specific environments. Consequently, cognitive biases remain characterized relative to chosen normative baselines, which may differ from behavioral efficacy in non-formal contexts.
Why it matters
Systematic departures in judgment provide empirical foundations for behavioral economics and policy design, including default-enrollment interventions. Applied domains such as medical diagnosis, financial modeling, and algorithmic fairness examine these tendencies to identify structural risks and develop debiasing procedures.
