Abstract Previous studies have mainly explored the weakening effect of disadvantageous inequality on cooperation, while the role of advantageous inequality remains unclear. In the present work, a dyadic interaction scenario was created, and 32 participants were randomly presented with advantageous-unequal-, disadvantageous-unequal-, and equal distributions. Their cooperative behavior was measured in a subsequent chicken game, while their brain activity was recorded using electroencephalography (EEG). The results demonstrated that, compared with equal distribution, both advantageous- and disadvantageous-unequal distributions weaken cooperation, and the weakening effect of advantageous-unequal distribution was relatively smaller. The pattern of behavioral differences aligned with the patterns observed in the neural signs (FRN & P300). The present study fills a gap in existing research and sheds light on how to understand the relationship between fairness-related experience and subsequent cooperation.
