Low Self-Concept Clarity Induces Scarcity Perceptions: The Subsequent Effects on Prosocial Behavior.

We explore the relationship between self-concept clarity (SCC), scarcity perceptions, and the associated behavioral consequences. While scarcity perceptions are often linked to experiences and considerations of resource constraints, our research suggests that low SCC can induce such perceptions and decrease prosocial behavior. With six studies, we demonstrated that low SCC triggers scarcity perceptions (Studies 1A to 4B), which is mediated by increased social comparison orientation (Studies 2 to 4B). Furthermore, we found that the scarcity perceptions increased by low SCC further predict individuals' low inclination to engage in prosocial behaviors (Studies 3 to 4B). By establishing a link between SCC and scarcity perceptions, our research departs from the traditional focus on resource constraints, broadens the factors that induce scarcity perceptions, and extends our understanding of the societal implications of low SCC.
