Israeli cognitive and mathematical psychologist, a key figure in the study of systematic human cognitive bias and judgment under uncertainty. From the late 1960s he formed a long research partnership with Daniel Kahneman that reshaped how psychology and economics understand human decision-making.
Facts
Nationality / Culture Defining ContributionWith Daniel Kahneman, developed the heuristics-and-biases research program (1974) and, in 1979, prospect theory, showing that intuitive judgment under uncertainty relies on simplifying heuristics that produce systematic, predictable errors. 1 Notable WorkJudgment under Uncertainty: Heuristics and Biases (with Kahneman, 1974) 1 Amos Tversky
