In rational decision making these factors are combined using a model called “discounted expected utility”. Kennedy’s dealing with the Cuban Missile Crisis is usually cited as the classic example. The standard, Bayesian account of rational belief and decision is often argued to be unable to cope properly with severe uncertainty, of the sort ubiquitous in some areas of policy making. Besides, equating analysis with rationality implies that analysis is rational by definition (Evans and Stanovich 2013), although it is exactly this often implicitly held assumption that should be questioned in research … Decision-making involves the following phases: 1. In Rational Decision Making, supposedly all these factors are integrated by: 1) Defining the problem, 2) Ranking and choosing goals, 3) Identifying alternative actions and 4) Choosing an alternative. For example, under this model, a consequence received at a future time period t with a perceived probability p is valued p exp(-rt)u(x), where r is the discount rate that captures attitudes towards the future, and u is a utility function that characterizes risk attitudes.

Rational decision making requires executing an appropriate decision‐making process to select the best alternative. The decision maker is assumed to have complete information regarding the decision situation.
