I own, so I help out: How psychological ownership increases prosocial behavior, Journal of Consumer Research
Ownership is prevalent in everyday life. This research examines the consequences of psychological ownership on cognitions and behaviors from a novel perspective that goes beyond the behaviors directed toward the owned entity. Specifically, we show that psychological ownership increases prosocial behavior and that self-esteem explains this relationship. In our studies, ownership leads to a boost in self-esteem, which encourages individuals to be more helpful. Additionally, we show that the effect of ownership on prosocial behavior is not driven by self-efficacy, perceived power, reciprocity, feeling well-off, or affect. Moreover, we examined materialism and mine-me sensitivity as individual differences moderating the effect of ownership on prosocial behavior, showing that our proposed effect did not hold for individuals low on materialism or low on mine-me sensitivity. Finally, we attenuated the effect of ownership on prosocial tendencies by making the negative attributes of oneâ€™s possessions relevant. Together, our studies show that when people experience psychological ownership, its consequences can go beyond the specific relationship with the possession to guide behavior in unrelated situations.
