Furthermore, we also found no link between inequality aversion and increase in happiness (tested by Pearson correlation; n=48, across groups: advantageous r=−0.06, P=0.67 disadvantageous r=−0.14, P=0.33; experimental group: advantageous r=−0.3, P=0.15 disadvantageous r=−0.09, P=0.67; control group: advantageous r=−0.16, P=0.47 disadvantageous r=−0.14, P=0.51).
