Justifying Outcomes Versus Processes: Distributive and Procedural Justice Beliefs as Predictors of Positive and Negative Affectivity

System justifying beliefs can have adaptive consequences for individuals that include enhanced coping and decreased emotional distress. The present study examined whether individual differences in two kinds of system justifying beliefs uniquely predict dispositional affect. Participants from across the United States were recruited via internet to complete dispositional measures of procedural and distributive justice beliefs, and also brief measures of positive and negative affectivity. While belief in fair outcomes (distributive just world beliefs) was generally associated with greater positive affectivity, belief in fair processes (procedural just world beliefs) was modestly associated with decreased negative affectivity. In addition, positive and negative affectivity were predicted by interactions between procedural and distributive just world beliefs, with each accentuating the general emotional benefit provided by the other. Finally, an interactive effect of procedural just world beliefs and social class was obtained for positive affectivity, with greater positive affectivity occurring for disadvantaged (lower income) individuals who had strong procedural just world beliefs. In general, these results suggest the potential for unique and interactive relationships between particular system justifying beliefs and measures of emotion, especially among members of advantaged versus disadvantaged groups.
