SAN FRANCISCO (AP) — Daniel Kahneman, a psychologist who won a Nobel Prize in economics for his insights into how ingrained neurological biases influence decision making, died Wednesday at the age of 90. In an excerpt from his book, Kahneman described a “leaderless group” challenge used by the Israeli army's Psychology Branch to assess future leadership potential. “It was the first cognitive illusion I discovered,” Kahneman later wrote. “The experience was magical,” Kahneman later wrote in his Nobel autobiography. Combined with other findings, the pair developed a theory of risky choice they eventually named “prospect theory.”Kahneman received the Nobel Prize in economics in 2002 for these and other contributions that ended up underpinning the discipline now known as behavioral economics.
