	Decision Science News: Amos Tversky
		Although [Tversky’s] best known work was contained in his papers on the heuristics of judgment and on sources of suboptimal decision making, Amos also made major contributions to many other areas of psychology, from the foundations of measurement to the nature of similarity assessment and the misperception of randomness or chance.
		Amos Tversky (March 16, 1937 - June 2, 1996) was one of the leading Psychologists of the 20th century, best known for the research program he advanced, in collaboration with Daniel Kahneman, generally known as the Heuristics and Biases program.
		Tversky received his doctorate from the University of Michigan in 1965, and later taught at the Hebrew University in Jerusalem, before moving to Stanford University.

	Memorial Resolution for Amos Tversky
		Amos' contributions to the social sciences, and to Stanford, were monumental and will continue to make their influence felt for years to come.
		Amos' work already has exerted a major impact not only on virtually every subdiscipline of psychology, but also in statistics, law, medicine, business, and other fields in which decision makers must weigh costs and benefits in the face of uncertainty.
		Amos, then a 19 year old lieutenant, but destined to become a world authority on risk assessment and decision making, knew the explosion would occur within a few seconds.

		The same mental foible, Tversky and Kahneman discovered, lies at the heart of the familiar ''gambler's fallacy.'' After witnessing a long run of red on a roulette wheel, for example, gamblers often become extremely confident that the next spin will be fl, when in fact the chances remain at roughly 50 percent.

	Amos Tversky's contributions to legal scholarship: Remarks at the BDRM session in honor of Amos Tversky, June 16, 2006
		Prospect theory undermines the Coase Theorem, which is the bedrock of traditional law and economics; and the heuristics and biases research questions the fundamental idea of a rational self-interested decisionmaker, which is also challenged by subsequent studies of the role of affect in judgment and decisionmaking.
		To place Amos Tversky's contributions to legal scholarship in context, I'll begin with an incredibly brief and oversimplified history of the role of the social sciences in the legal academy.
		Although this was not the major focus of Amos Tversky's work, the lines of thought certainly trace back to him, for example through the pioneering work of his collaborator Paul Slovic.

		Amos Tversky died at age 59 on Sunday at his home in Stanford, Calif.
		Tversky once said he merely examined in a scientific way things about behavior that were already known to "advertisers and used-car salesmen," and much of his work has indeed had an economic slant, shaping the way economists look at decision making by consumers and business executives.
		Tversky got his bachelor's degree from Hebrew University in 1961 and his doctorate from the University of Michigan in 1965.

	Kahneman and Tversky's Prospect Theory
		Daniel Kahneman and Amos Tversky called their studies of how people manage risk and uncertainty Prospect Theory for no other reason than that it is a catchy, attention-getting name.
		Kahneman and Tversky's theory, developed over a thirty year period, is however highly important in economics and especially in financial economics.

	Choices, Values, and Frames by Daniel Kahneman, Amos Tversky
		However, the first article in the book, which was published by Kahneman and Tversky in 1983, should probably be read by everyone interested in prospect theory and its foundations.
		Daniel Kahneman and the late Amos Tversky are two of the Godfathers of behavioural economics - and their body of work since the 1970s gave a really firm yank on the rug of rationality that had thus-far supported traditional theories of human economic behaviour.
		Kahneman and Tversky and their good company of researchers demonstrate that if we shine the spotlight on the decision-making processes of humans we can uncover many, many answers to why we behave as we do.

		Psychologists in this field such as Ward Edwards, Amos Tversky and Daniel Kahneman began to benchmark their cognitive models of decision making under risk and uncertainty against economic models of rational behavior.
		Perhaps the most important paper in the development of the behavioral finance and economics fields was written by Kahneman and Tversky in 1979.
		Further milestones in the development of the field include a well attended and diverse conference at the University of Chicago (see Hogarth and Reder, 1987) and a special 1997 edition of the respected Quarterly Journal of Economics ('In Memory of Amos Tversky') devoted to the topic of behavioral economics.

		Amos is a dominant figure in cognitive psychology and behavioral decision theory.
		As a result, the message that people are intellectually error-prone has spread far from the critical academic environments that gave it birth, and has had important influences in a wide variety of contexts.
		Another research domain in which Amos was a leader was the axiomatic and mathematical foundations of measurement, especially measurement of behavior.

		Daniel Kahneman is co-winner of the 2002 Nobel Memorial Prize in Economic Sciences.
		The award was bestowed in recognition of the influential research conducted by Kahneman and his long-time collaborator, the late Amos Tversky, on the psychology of human judgment and decision-making.
		According to a recent article published in the journal Psychological Science, the research program initiated by Kahneman and Tversky is considered psychology’s "leading intellectual export to the wider academic world." Current scholarship and research in medicine, law, public policy, international relations, and economics has been profoundly shaped by their insights into human rationality.
