Amos Tversky

Amos Nathan Tversky, PhD (March 16, 1937 - June 2, 1996) was a cognitive and mathematical psychologist, and a pioneer of cognitive science, a longtime collaborator of Daniel Kahneman, and a key figure in the discovery of systematic human cognitive bias and handling of risk. Much of his early work concerned the foundations of measurement. He was co-author of a three-volume treatise, Foundations of Measurement (recently reprinted). His early work with Kahneman focused on the psychology of prediction and probability judgment. Later, he and Kahneman originated prospect theory to explain irrational human economic choices. Daniel Kahneman's autobiography for the Nobel Prize webpage contains a rich account of Tversky's personal and professional qualities and a eulogy, starting with the section "Collaboration with Amos Tversky." Daniel Kahneman received the Nobel Prize for the work he did in collaboration with Amos Tversky, who would have no doubt shared in the prize had he been alive
