What determines people’s fairness judgments? Identification and outcomes influence procedural justice evaluations under uncertainty

Abstract

When the procedures people experience are uncertain, factors unrelated to principles of procedural justice may nevertheless shape procedural justice judgments. This paper investigates two of these factors: an individual’s level of social identification with the group enacting the procedures and the outcomes associated with the procedure. It was predicted and found that high (vs. low) levels of identification promote relatively positive perceptions of procedural justice. It was also predicted and found that desirable (vs. undesirable) outcomes promote relatively positive perceptions of procedural justice. These effects only emerged in the absence of direct information indicating whether procedures were (un)fair. By showing an influence of identification and outcomes on procedural justice judgments under conditions of informational uncertainty, these studies provide important experimental evidence that integrates and extends previous research on justice, identity, and uncertainty to understand subjective evaluations of process fairness.
