 On this suggestion, then an act is valued by the sum of the marginal utility contributions of the outcomes, each multiplied by the capacity of the event given which that act would yield an outcome that is at least as preferable. There are obvious formal similarities here with RDU and, in fact, the latter can be viewed as the special case of CEU in which the decision maker’s capacities are derived from his or her probabilistic degrees of belief by a probability weighting function (\(v=w\circ  P\)).[11]
