From: Increasing altruistic and cooperative behaviour with simple moral nudges
Moral nudges spill across contexts. Results of Study 4, second stage game (N = 537). Subjects who are nudged in a first-stage DG (resp. PD) tend to be more pro-social in a subsequent non-nudged PD (resp. DG) than those who are not nudged. A meta-analysis of the four conditions yields a significant positive spillover effect whose size is also relatively large (overall effect size = 0.633, 95% CI [0.047,1.219], Z = 2.12, p = 0.034), providing evidence that a significant proportion of the effect of moral nudges on first-stage behaviour spills across contexts. The y-axis represents the average percentage of the endowment given by subjects in second-stage game in the corresponding first-stage condition. Error bars represent +/− SEM. We refer to the Supplementary Material, Table SM5, for regression details, and Fig. A1, for the forest plot of the meta-analysis.
