Abstract The relationship between beauty and goodness has always been an important topic of scholars to debate, but at present, most researchers only use moral words to study a one-way relationship. In this study, behavioral and EEG experiments were used to select facial attractiveness to represent “beauty” and fairness to represent “goodness” in an attempt to explore the relationship between beauty and goodness in the same context. Experiment 1 used ultimatum game task variant to investigate the influence of facial attractiveness on individual fairness. The results showed that individuals were more willing to accept the proposal of highly attractive faces, highly attractive faces induced greater N2 amplitude, lowly attractive faces induced greater P2 amplitude and FRN amplitude, and the FRN amplitude was greater in women. Experiment 2 used the dictator game task variant to investigate the influence of fairness on individuals’ perceived attractiveness. The results showed that the fair proposers were more attractive, and the lowly attractive faces induced greater N2 amplitude, and the P2 amplitude was larger in men. In conclusion, facial attractiveness can affect an individual’s perceived fairness; Fairness affects an individual’s perception of face attractiveness, but is influenced by the attractiveness of the face itself.
