The mythological Judgement of Paris required selecting from three incomparable alternatives (the goddesses shown).. Decision theory or the theory of rational choice is a branch of probability, economics, and analytic philosophy that uses the tools of expected utility and probability to model how individuals would behave rationally under uncertainty.
Rational choice theory, a cornerstone of microeconomics, builds this postulate to model aggregate social behaviour. The expected utility hypothesis states an agent chooses between risky prospects by comparing expected utility values (i.e., the weighted sum of adding the respective utility values of payoffs multiplied by their probabilities).
March and Olsen distinguish the logic of appropriateness from what they term the "logic of consequences," more commonly known as rational choice theory.The logic of consequences is based on the assumption that actors have fixed preferences, will make cost-benefit calculations, and choose among different options by evaluating the likely consequences for their objectives.
When using this model, the following conditions are assumed. The decision will be completely rational in a means-ends sense; There is a complete and consistent system of preferences that allows a choice among alternatives; There is a complete awareness of all the possible alternatives; Probability calculations are neither frightening nor mysterious
