Morality and justice: An expanded theoretical perspective and empirical review

Two metaphors of human motivation have dominated justice theory and research: homo economicus (people as rational utility maximizers) and homo socialis (people as status and social value maximizers). This chapter reviews theory and research inspired by a recent third perspective: homo moralis, that is, people as innately concerned about morality. When people have strong moral convictions at stake, their perceptions of outcome fairness and decision acceptance are shaped more by whether outcomes are consistent with perceivers’ moral priorities than by whether authorities act in procedurally fair ways; moreover, whether authorities yield morally correct outcomes shapes subsequent perceptions of the legitimacy of these authorities or authority systems. Emotion plays an important role in both of these effects.
