Daniel Kahneman

Daniel Kahneman (1934–2024) was an Israeli-American psychologist whose research transformed the study of judgment and decision-making. Born in Tel Aviv and raised partly in France, he later studied at the Hebrew University of Jerusalem and earned a PhD in psychology at the University of California, Berkeley. With Amos Tversky, he developed Prospect Theory, showing how people evaluate gains and losses in ways that depart from classical economic rationality. Kahneman taught at the Hebrew University and later at Princeton University. In 2002 he received the Nobel Memorial Prize in Economic Sciences for integrating psychological insights into economics. He authored *Thinking, Fast and Slow* (2011).
