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. Rational Decision Making can be simplistically described as a 2 stage process – the first being problem identification and the second in problem solution. 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 … An alternative framework emphasizing cultural, structural and processual factors is offered as a more useful guide to effective decision making.

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. (Our actions and beliefs are justifiable [or reasonable/rational] as a function of the trustworthiness of the evidence, and the extent to which we believe that evidence is determined by credible processes.) Their decisions are rooted in their own knowledge, experience, and rationale, rather than going to others for more information. According to this view, medical rational decision making is associated with regret‐averse decision processes. This paper tackles the question of what should replace it as a guide for rational decision making. As well as showing that rational decision making is consistent with empirical observations of collective behavior, this model makes several testable predictions about how individuals make decisions in groups and offers a valuable perspective on how we view sources of variability in animal, and human, behavior. Identifying the Problem: The first step in the decision-making process is to identify the actual cause of a problem. Assuming that the decision maker … The paper suggests that the foreign language effect may not increase the chances of bilingual individuals being more rational decision makers in general, but may promote more rational behaviour in specific decision contexts.
