This review analyzes research and theory pertaining to the psychology of injustice, using as its organizing theme the role that the perception of disrespect plays in the experience of injustice. The analysis focuses primarily on the links between disrespect and anger, disrespect and injustice, and anger and injustice. Determinants of the intensity of people's reactions to injustices are also reviewed. In addition, the review examines the goals of retaliation as well as the forms that retaliation can take. Parallels between justice reactions to those acts of disrespect directed toward the self and those directed toward others are noted. Finally, the review discusses the implications of justice research for understanding the specific and general entitlements that people believe are their due.
