Kahneman wins Nobel Prize in Economics

Kahneman receives the Nobel Prize for research on cognitive biases and decision-making. The first psychologist to win the Economics Nobel.

The 2002 Nobel Prize in Economics was awarded to Daniel Kahneman for integrating psychological research into economic science, particularly regarding human judgment and decision-making under uncertainty. He shared the prize with Vernon Smith.

Kahneman and his collaborator Amos Tversky (who died in 1996) identified heuristics such as representativeness, availability, and anchoring, demonstrating that people do not follow the rational models of classical economics.

Prospect Theory, formulated by Kahneman and Tversky in 1979, showed that people value losses roughly twice as much as equivalent gains — a phenomenon known as loss aversion.

This prize legitimized decades of research on cognitive biases and established psychology as a fundamental discipline for understanding economic and social behavior.

Significance: This is one of the most significant developments in the psychology of our time. Its repercussions continue to be felt years later and have fundamentally changed how we understand the human mind and clinical practice.
