The Effect of Group Attachment and Social Position on Prosocial Behavior. Evidence from Lab-in-the-Field Experiments

Figure 3

Holding a formal position increases prosocial behavior toward in-group members.

Farmer group leaders allocated to members, on average, 0.40 s MU more than regular farmer-group members (). Leaders in the village gave, on average, 0.23 MUs more to co-villagers than regular villagers (). The contribution of both types of leaders did not differ from average group members when receivers were either strangers or members of a group in which they did not hold formal leadership positions. Predicted average contributions derived from multilevel regressions in which we model the contribution to strangers, villagers and farmer group members, controlling for individual and group level characteristics. Whiskers indicate the 95% interval, while the difference between regular members/villagers and leaders and its significance is reported in the graph. See SI Appendix, Table 1 for results in tabular form.
