Amos Tversky (March 16, 1937 - June 2, 1996) was 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. With Kahneman, he originated prospect theory to explain irrational human economic choices. He received his doctorate from the University of Michigan in 1965, and later taught at the Hebrew University in Jerusalem, before moving to Stanford University. In 1984 he was a recipient of the MacArthur Fellowship.
