Quick Summary

Amos Tversky was an Israeli psychologist known for his groundbreaking work on human judgment and decision-making under uncertainty. He collaborated extensively with Daniel Kahneman, another Israeli psychologist, to develop prospect theory. This theory, which integrates psychological insights into economic science, challenged traditional economic models by demonstrating how people often rely on mental shortcuts, or heuristics, rather than purely rational calculations when making decisions. Their research highlighted systematic biases that can arise from these heuristics, significantly influencing fields such as economics, psychology, and political science. Kahneman and Tversky's work earned Kahneman a share of the Nobel Prize in Economics in 2002.123
