Authorities' knowledge of shared group membership and its effects on the respect-informing properties of procedural fairness

We observe that the voice-leads-to-respect process underlying relational models of procedural fairness is assumed to follow primarily if not solely from interaction with an in-group authority. Moreover, if the voice recipients believe that the authority is unaware of this shared group membership, then the provision of voice actually says nothing (to the voice recipients) about their standing as group members; the respect-providing information as valued in-group members is absent because the recipients know that the authority does not know of their shared group membership. We tested these assumptions in a three-way design manipulating the group membership of the authority (in-group vs. out-group), the nature of voice (provided vs. denied) and the nature of group membership knowledge (the authority knows or does not know the voice recipient's group membership). A significant three-way interaction was found, as predicted, on respect and fairness ratings. These data provide clear experimental support for an unstated, and yet untested, assumption of relational models of procedural fairness.
