When being disadvantaged grows into vengeance: The effects of asymmetry of interest and social rejection in social dilemmas

In public good dilemmas, group members often differ in the extent to which they benefit from provision of the public good (asymmetry of interest). In the current paper, we argue that people may readily accept such financial differences in interest when their social needs are met by being accepted by the others. When people are socially rejected, however, members having a low rather than a high interest in the public good may display negative emotional and retributive reactions. This reasoning was supported by the findings of a first experimental study in which we manipulated people's interest in the public good and social rejection. These effects were replicated in a second experimental study and it was further shown that this two-way interaction between social rejection and interest in the public good was moderated by people's social value orientation. The negative reactions to low interest (vs. high. interest) in the public good when being socially rejected were especially prominent among group members with a proself orientation. Taken together, the current studies illustrate the importance of studying how financial and social needs interact to determine emotional and retributive actions in social dilemmas.
