When do we need procedural fairness? The role of trust in authority

On the basis of fairness heuristic theory, the authors argue that when information about whether an authority can be trusted is not available, people will resolve the question of how they should interpret the decisions of the authority by relying on perceived procedural fairness. As a consequence, people who do not have information about authority's trustworthiness react more positively toward the outcomes of authority's decisions if the authority is using fair as opposed to unfair procedures. However, when people know that the authority either can or cannot be trusted, they are less in need of procedural fairness information, yielding less strong effects of procedural fairness on people's reactions. The findings of 2 experiments support the authors' line of reasoning. It is concluded that people especially need procedural,fairness when information about an authority's trustworthiness is lacking.
