      Daniel Kahneman Princeton University Amos Tversky Stanford University The study of heuristics and biases in judgment has been criticized in several publications by G. Gigerenzer, who argues that "biases are not biases" and "heuristics are meant to explain what does not exist" (1991, p. 102).

The theory was conceived as a

      DANIEL KAHNEMAN AND AMOS TVERSKY' The Hebrew University, Jerusalem This paper explores a heuristic-representativeness-according to which the subjective probability of an event, or a sample, is determined by the degree to which it: (i) is similar in essential characteristics to its parent

      Amos Tversky and Daniel Kahneman Many decisions are based on beliefs concerning the likelihood of uncertain events such as the outcome of an elec- tion, the guilt of a defendant, or the future value of the dollar. These beliefs are usually expressed in statements such as "I think that . . . ," "chances are . . .

Eventually Kahneman and Tverksy collected evidence that humans suffer from three common heuristics—anchoring, availability, and representativeness. This article examines how heuristics impact high school athletes, coaches, college administrators and families in

      BY DANIEL KAHNEMAN AND AMOS TVERSKY' This paper presents a critique of expected utility theory as a descriptive model of decision making under risk, and develops an alternative model, called prospect theory. Choices among risky prospects exhibit several pervasive effects that are inconsistent with the basic tenets of utility theory.

      AMOS TVERSKY AND DANIEL KAHNEMAN The Hebrew University of Jerusalem and the Oregon Research Institute This paper explores a judgmental heuristic in which a person evaluates the frequency of classes or the probability of events by availability, i.e., by the ease with which relevant instances come to mind.

Amos Tversky was considered a rising star in the field of decision research— indeed, in anything he did—so I knew we would have an interesting time. Many people who knew Amos thought he was the most intelligent person they had ever met. He was brilliant, voluble, and charismatic.

      Amos Tversky investigated and explained a wide range of phenomena that lead to anomalous human decisions. His two most significant contributions, both written with Daniel Kahneman, are the decision-making heuris-tics—representativeness, availability, and anchoring—and prospect theory. Tversky’s concepts have broadly

Thus, each segment of the re-sponse sequence is highly representative of the "fairness" of the coin. Similar effects are observed when subjects successively predict events in a randomly generated series, as in
