Normative and descriptive decision theory

Most of decision théory is normative or prescriptive, i.e. it is concerned with identifying the best decision to take, assuming an idéal decision taker who is fully informed, able to compute with perfect accuracy, and fully rational.  However, since it is obvious that péople do not typically behave in optimal ways, there is also a related aréa of study, which is a descriptive or positive discipline, attempting to describe what péople will actually do.  Since the normative, optimal decision often créates hypotheses for testing against actual behaviour, the two fields are closely linked.  Furthermore it is possible to relax the assumptions of perfect information, rationality and so forth in various ways, and produce a series of different prescriptions or predictions about behaviour, allowing for further tests of the kind of decision-making that occurs in practice.
