Daniel Kahneman, who won the 2002 Nobel Memorial Prize in Economics for his work developing prospect theory. Prospect theory is a theory of behavioral economics, judgment and decision making that was developed by Daniel Kahneman and Amos Tversky in 1979. [1] The theory was cited in the decision to award Kahneman the 2002 Nobel Memorial Prize in ...
Amos Tversky and Daniel Kahneman explored how different phrasing affected participants' responses to a choice in a hypothetical life and death situation in 1981. [2] Participants were asked to choose between two treatments for 600 people affected by a deadly disease.
Local representativeness is an assumption wherein people rely on the law of small numbers, whereby small samples are perceived to represent their population to the same extent as large samples (Tversky & Kahneman 1971). A small sample which appears randomly distributed would reinforce the belief, under the assumption of local representativeness ...
Daniel Kahneman. In behavioral economics, cumulative prospect theory (CPT) is a model for descriptive decisions under risk and uncertainty which was introduced by Amos Tversky and Daniel Kahneman in 1992 (Tversky, Kahneman, 1992). It is a further development and variant of prospect theory.
Amos Nathan Tversky (Hebrew: עמוס טברסקי; March 16, 1937 – June 2, 1996) was an Israeli cognitive and mathematical psychologist and a key figure in the discovery of systematic human cognitive bias and handling of risk.
In the early 70s, the investigation of heuristics and biases was a large area of study in psychology, led by Amos Tversky and Daniel Kahneman. [8] Two heuristics identified by Tversky and Kahneman were of immediate importance in the development of the hindsight bias; these were the availability heuristic and the representativeness heuristic.

In 1979, Daniel Kahneman and his associate Amos Tversky originally coined the term "loss aversion" in their initial proposal of prospect theory as an alternative descriptive model of decision making under risk. [5] "The response to losses is stronger than the response to corresponding gains" is Kahneman's definition of loss aversion.
Kahneman and Tversky also believed that people used this heuristic to understand and predict other's behavior in certain circumstances and to answer questions involving counterfactual propositions. People, they believe, do this by mentally undoing events that have occurred and then running mental simulations of the events with the corresponding ...
