Information distortion in self-other decision making

In both organizational and social arenas, individuals make decisions for themselves and for other individuals. But research in decision making has provided little input into whether or how these decisions are psychologically different. In this paper, I propose that decisions—depending on whom they are for—vary according to the extent of information distortion, such that, individuals who choose for themselves demonstrate more postdecisional distortion, yet less predecisional distortion than individuals who choose on behalf of others. To test this hypothesis, participants in an experiment made a decision between two restaurants. Attributes about each restaurant were presented sequentially, and preferences were measured following each attribute. As expected, participants who chose for themselves experienced more postdecisional distortion. However, among participants who chose on behalf of others, greater distortion of predecisional attribute information was observed. These findings shed light on the differences in self-other decision making, as well as on research concerning information distortion.
