Nobel Prize-winning psychologist Daniel Kahneman, known for pioneering theories in behavioral economics, has passed away at the age of 90. He died peacefully on Wednesday, March 27, according to a release from Princeton University, where he had been a faculty member since 1993. The cause of death was not provided.

Kahneman authored the best-selling book "Thinking, Fast and Slow," challenging the idea of rational decision-making and highlighting the role of instinct in human behavior. His work had a profound impact on the social sciences, as noted by his colleague Eldar Shafir.

Born in Tel Aviv in 1934, Kahneman's family moved to Paris when he was three months old. During the Nazi occupation of France, they were forced into hiding to escape deportation. After the war, Kahneman moved to British-ruled Palestine with his mother, following the death of his father in 1944.

In 2002, Kahneman was awarded the Nobel Prize in Economics for his collaborative work with Amos Tversky, focusing on the flaws in intuitive reasoning. The Royal Swedish Academy of Sciences recognized Kahneman's integration of psychology into economics, particularly regarding human judgment and decision-making under uncertainty.
