Decision theory can be broken into two branches: normative decision theory, which gives advice on how to make the best decisions, given a set of uncertain beliefs and a set of values; and descriptive decision theory, which analyzes how existing, possibly irrational agents actually make decisions.
Descriptive and prescriptive studies differ in how the user's decision rules (which comprise a decision model) are obtained. In a prescriptive study, the decision model is based on a normative theory (e.g., decision theory) that specifies an optimal set of decision rules (e.g., maximize subjective expected utility).
