- 1Uses expected utility and probability to model choices.
- 2Functions as a prescriptive theory for rational agents.
- 3Distinguished from descriptive behavioral sciences.
- 4Provides foundations for economics and political science.
- 5Analyzes decision-making under conditions of uncertainty.
Decision theory or the theory of rational choice is a branch of probability, economics, and analytic philosophy that uses expected utility and probability to model how individuals would behave rationally under uncertainty.

theoretical framework for opportunity cost analysis
Rational choice theory assumes that individuals make decisions by weighing the benefits and opportunity costs of all available options to maximize utility.
Decision theory, also known as the theory of rational choice, is an interdisciplinary field that models how individuals make decisions under conditions of uncertainty. By utilizing expected utility and probability, the theory provides a mathematical framework to identify the optimal course of action for a rational agent. It is primarily prescriptive, focusing on what a rational actor should do rather than describing how humans actually behave in practice.

It provides the foundational logic for modeling behavior in diverse fields such as economics, sociology, and political science. By establishing clear criteria for rationality, the field allows researchers to analyze and predict how individuals might navigate complex choices in moral philosophy and other analytical domains.
