Solidarity and Social Justice: Effect of Individual Differences in Justice Sensitivity on Solidarity Behaviour

摘要

We investigate the effect of individual differences in justice sensitivity (JS) on giving behaviour in a solidarity game, its potential moderators and the underlying psychological mechanisms. In a solidarity game, subjects are asked to make decisions about transferring money to other players in a case in which they win a random draw and the other players lose. The results of four studies showed the following: (1) JS explains a unique portion of variance in the solidarity behaviour, above and beyond other basic personality dimensions (e.g. HEXACO model); (2) its effect does not depend on contextual factors, such as the degree of moral entitlement not to share and the possibility to attribute the recipients' disadvantage to their own responsibility; and (3) individual differences in the emotions anticipated in response to different outcomes of a random draw and the cognitive interpretation of the allocation situation partially mediate the effect of JS on solidarity behaviour. We also provided the first evidence that JS predicts individual differences in the propensity to take away others' earnings (antisocial behaviour). The results are discussed with respect to the research on personality as a predictor of prosocial and antisocial behaviour. Copyright (c) 2015 European Association of Personality Psychology
