Cognitive Bias
Cognitive biases are systematic patterns of deviation from rational judgment — mental shortcuts that evolved to enable fast decision-making but produce predictable errors in modern contexts.
Overview
Kahneman and Tversky's research demonstrated that humans consistently violate rational choice axioms, transforming psychology from a discipline that assumed rationality to one that cataloged systematic departures; this work won the Nobel Prize in economics for connecting behavioral evidence to economic theory. Cognitive biases reflect evolved properties of neural processing — availability, loss aversion, and in-group favoritism all have plausible evolutionary origins.
Why it matters
Understanding cognitive biases has been critical to explaining behavior in financial markets, political reasoning, and organizational decision-making — and has driven the field of behavioral economics, which now shapes public policy through 'nudge' interventions. In technology, AI systems trained on human-generated data can amplify human biases, making bias detection and mitigation a major challenge in machine learning fairness.
