Origin

Prospect Theory arose as a framework for explaining kT79; reference dependence, value function, weighting. On the Prospect Theory record, kT79; reference dependence, value function, weighting; no universal prediction claim.

History

In this Prospect Theory context, this explanatory model sits between Simon's account of bounded rationality and the experimental study of judgment under uncertainty. Applied specifically to Prospect Theory, its history matters because a descriptive pattern, a normative model, and a practical intervention make different claims.

Core Principles

For Prospect Theory, the first principle states the focal choice problem and available information. On the Prospect Theory record, the second specifies a benchmark and not assuming perfect optimization. In this Prospect Theory context, the third tests how performance changes across environments, representations, or feedback conditions. Applied specifically to Prospect Theory, consider a decision in which prospect theory changes which evidence is noticed, which comparison is selected, or which action is taken. For Prospect Theory, the page tests that change against an explicit alternative and not treating the label as an explanation.

Important Figures

On the Prospect Theory record, the assigned source trail begins with Daniel Kahneman and Amos Tversky and is checked against Judgment under Uncertainty: Heuristics and Biases. In this Prospect Theory context, credit follows named publications; later popularizers do not replace original authors.

Modern Influence

Prospect Theory informs forecasting, policy, finance, medicine, organizations, and AI-assisted judgment when its assumptions match the decision exercise. Applied specifically to Prospect Theory, a useful application changes data collection or decision procedure, not merely vocabulary.

Criticism

For Prospect Theory, the conclusion is bounded by the decision exercise, population, measurement, and comparison described in the cited research; a catchy bias name is not a diagnosis of a person. On the Prospect Theory record, critics also dispute whether laboratory norms always capture adaptive success. In this Prospect Theory context, the page as a result reports both the demonstrated pattern and the environmental conditions under which an alternative interpretation becomes plausible.

Evidence Audit

The available evidence audit for Prospect Theory begins with a narrow claim: kt79; reference dependence, value function, weighting. The first cited record, Prospect Theory: An Analysis of Decision under Risk, is used for that owned proposition. For Prospect Theory, the second source supplies a comparison or field-level boundary. On the Prospect Theory record, neither source is treated as authority for facts it does not report.

In this Prospect Theory context, a reader can reproduce the audit by recording the decision exercise, participants or decision setting, comparison, outcome, and uncertainty. Applied specifically to Prospect Theory, consider a decision in which prospect theory changes which evidence is noticed, which comparison is selected, or which action is taken. For Prospect Theory, the page tests that change against an explicit alternative and not treating the label as an explanation. On the Prospect Theory record, this example is illustrative until a cited design tests the same mechanism. In this Prospect Theory context, it cannot establish a population rate, individual diagnosis, or universal law.
