✦ Synopsis
Three reasons for why people may evaluate utility in a rank-dependent fashion have been suggested: (a) rank-dependent weighting is a function of perceptual biases and thus not prescriptively defensible; (b) weights are (re)distributed by motivational processes that reflect stable personality characteristics of the decision maker;and (c) weights are (re)distributed as a function of the situation, allowing rank-dependent evaluation to be a rational response to an environment with asymmetric loss functions. By modifying a study by Wakker, Erev, and Weber (1994) we show that all three processes-that is, perceptual biases, individual predispositions in weighting, as well as rational adaptation to an asymmetric loss function-can be involved in rank-dependent weighting.
