Long-term focus and prosocial-antisocial tendencies interact to predict belief in just world

According to justice motive theory, individuals need to believe that the world is a just place where people generally get what they deserve (Lerner, 1977). Individuals are thought to need belief in a just world (BJW) in part because it gives them the confidence required to invest in long-term goals. However, BJW can only provide confidence that individuals will reap the rewards of their investments if they invest in their goals through prosocial means (e.g., Hafer, 2000). The current study provides evidence for this argument. Specifically, we examined individual differences in BJW, long-term goal focus, and prosocial-antisocial tendencies to test the hypothesis that higher long-term focus would be associated with higher BJW, but only amongst those who are also high in prosocial (low in antisocial) tendencies. This hypothesis was tested four times using four measures of prosocial-antisocial tendencies. Simple slopes analyses revealed the predicted pattern of results for three of the four measures. Our findings (a) provide novel support for the idea that BJW aids in the prosocial pursuit of long-term goals, and (b) have implications for individual variation in BJW.
