Abstract: A substantial amount of research has demonstrated that good-looking individuals are perceived and treated in a favorable manner; however, relatively little research has examined how attractive people actually behave. There are two predominant theories on attractiveness: the self-fulfilling nature of “what is beautiful is good” from social psychology and the evolutionary perspective of attractiveness, make divergent predictions in this regard. The current research systematically investigated whether physical attractiveness can predict self-interested behavior and, if so, in which direction. Across five studies (N = 1303), self-perceived attractiveness, either chronically experienced (Studies 1–3) or temporarily heightened (Studies 4 and 5), predicted and increased self-interested behavioral intention and behavior. Increased psychological entitlement acted as a mediator in this process (Studies 1–5). Furthermore, the publicity of the act was a boundary condition for the effect of attractiveness on self-interested behavior (Study 5). We have discussed theoretical and practical implications.
