A Meritocratic Origin of Egalitarian Behaviour
研究不确定性（即人们不确定不平等是源于能力还是运气）如何影响分配行为，发现不确定性会促使多数精英主义者转向平等主义，理论模型得到美国和挪威人口调查支持。
Abstract We report from a study of how uncertainty about whether a given inequality reflects performance or luck shapes distributive behaviour. We show theoretically that the reaction to uncertainty depends on how people trade-off the probability of making a mistake when redistributing, and the size of this mistake. We show experimentally that uncertainty causes a strong egalitarian pull among a majority of meritocratic individuals. The theoretical framework and the experimental results are supported in general population surveys in the United States and Norway. Our findings suggest that how people handle uncertainty about the source of inequality may be of great importance for understanding distributive conflicts in society.
