Of different minds: an accessible identity model of justice reasoning.

An accessible identity model (AIM) of justice reasoning is introduced to explain when people become concerned about justice and how they define what is fair or unfair once justice concerns are activated. This model has two core propositions: (a) People are most likely to think about justice and fairness when self-relevant values and goals are highly accessible or activated, and (b) how people define fairness depends on which aspect of the self (i.e., material, social, or personal and moral) dominates the working self-concept. A review of the literature indicates that this general model provides an integrative account for when and how people become concerned about both procedural and distributive justice, and provides a cogent explanation for known effects and results previously thought to be anomalies. Finally, the model generates novel hypotheses about how identity threat may lead to motivated perceptions of fairness or unfairness.
