Toward understanding why fairness matters: the influence of mortality salience on reactions to procedural fairness.

This article focuses on the question of why fairness matters to people. On the basis of fairness heuristic theory, the authors argue that people especially need fairness when they are uncertain about things that are important to them. Following terror management theory, the authors focus on a basic kind of human uncertainty: fear of death. Integrating these two theoretical frameworks, it is proposed that thinking about their mortality should make fairness a more important issue to people. The findings of three experiments support the authors' line of reasoning: Asking participants to think about their mortality led to stronger fair process effects (positive effects of perceived procedural fairness on subsequent reactions) than not asking them to think about mortality. It is argued that these findings suggest that fairness especially matters to people when they are uncertain about fundamental aspects of human life such as human mortality.
