 A final approach treats global sensitivity as a feature of the decision-maker’s way of aggregating utility values. It might be that a decision-maker’s utility and probability function are not yet enough to tell us what he should prefer; he must also decide how much weight to give to what happens in worse states versus what happens in better states. In risk-weighted expected utility (Buchak 2013), a generalization of Quiggin’s (1982) anticipated utility and a member of the rank-dependent family (see  section 4.3.2),  this decision is represented by his risk function.
