An outstanding problem for decision theories of all stripes is the relationship between normative and descriptive considerations: how decisions should be made versus how people can or do actually make them. Prescriptive decision analysis is intended to meld both in a sensible way, for example by recognizing the importance of heuristics to simplify complex decision tasks. This presentation proposes that the multiple-values part of decision analysis, multiattribute utility theory, successfully embodies many desirable features for a prescriptive approach. A detailed correspondence with features of Aristotelian practical reason is provided.
