Daniel Kahneman, an Israeli American psychologist and best-selling author whose Nobel Prize-winning research upended economics — as well as fields ranging from sports to public health — by demonstrating the extent to which people abandon logic and leap to conclusions, died March 27. He was 90.
His death was confirmed by his stepdaughter Deborah Treisman, fiction editor at the New Yorker. She did not say where or how he died.
Dr. Kahneman’s research was best known for debunking the notion of “homo economicus,” the “economic man” who since the epoch of Adam Smith was considered a rational being who acts out of self-interest. Instead, Dr. Kahneman found, people rely on intellectual shortcuts that often lead to wrongheaded decisions that go against their own best interest.
These misguided decisions occur because humans “are much too influenced by recent events,” Dr. Kahneman once said. “They are much too quick to jump to conclusions under some conditions and, under other conditions, they are much too slow to change.”
