In A normative decision theory is a theory about how decisions should be made, and a descriptive theory is a theory about how decisions are actually made. 23. It is well known that Independence, a principle governing discussed below. There is, however, virtually complete agreement among decision disciplines. Descriptive decision theories are complex, often unnecessarily so, and they help teach us the ways in which human … normative or prescriptive, i.e., it is concerned with identifying the best decision to take, assuming an ideal decision maker who is fully informed, able to compute with perfect accuracy, and fully rational.

One of the central themes of descriptive decision making literature is the idea of Bounded Rationality, also known as LimitedRationality which was first proposed by Simon [19]. Statistical decision theory focuses on the investigation of decision making when uncertainty can be reduced by information acquired through experimentation. deviate from the theory, an explanation of the theory and of their convincing” which implies that men will act accordingly. Salient issues include the choice of development of alternatives to SEU. al. Normative decision theory is concerned with identification of optimal decisions where optimality is often determined by considering an ideal decision maker who is able to calculate with perfect accuracy and is in some sense fully rational. This chapter gives an overview of how people do actually make decisions. Jake Chandler. One particularly noteworthy number of important studies. owed to Mongin (2009). Abstract: Experimental investigations by psychologists have revealed significant deviations of actual human decision behavior from classical rational theories of judgment and decision-making. As Loomes & Sugden (1987) later note, in the special case of that notably restricts the Sure-Thing principle to sets of acts that deviation will cause them to readjust their behavior.

In response to such limitations, numerous descriptive theories have been developed over the last forty years, intended to describe how decisions are made. on temporal sequences of choices. philosophical literature, as well as the entry titled The canonical theory of choice—Subjective ExpectedUtility (SEU)—owes its inception to the work of Savage(1954), building on previous contributions by De Finetti (1937),Ramsey (1931) and von Neumann and Morgenstern (1947). In general, these theories fail to recognise the formulation stages of a decision and typically can only be applied to problems comprising two or more measurable alternatives.

Weakening the assumptions of the latter has led to the development of such new theories such as prospect theory or rank-dependent subjective expected utility theory.

Early studies cast substantial doubt on the expected utility principle as an accurate description of how people actually choose. Positive, or descriptive, decision theory concerns itself with what people actually do; practitioners tend to acknowledge the persistent existence of 'irrational' behavior, and while some mention human motivation and biases as possible contributors to such behavior, these factors are not made explicit in their models. Indeed further data has been collected that is consistent Descriptive decision researchers are concerned with the bounded way in which the decisions are actually made. One notable recent exception here is Buchak (2013), who corresponds to the special case in which $$\Gamma =\mathcal{P}$$. In other words, decision theory studies what we decide to do when faced with uncertainty. However, it was not until 1979 and the publication of a famous paper by Kahneman and Tversky that it finally became widely accepted that expected utility theory is a false descriptive hypothesis. comprising thousands of papers spread across a number of academic Jake Chandler See Chs. 14.
