Are beauty and goodness the same? The relationship between beauty and goodness has long been a controversial issue in the fields of philosophy, aesthetics, ethics and psychology. Although many empirical studies have explored moral judgment and aesthetic judgment separately, only a few studies have compared the two. Whether these two judgments are two different processes or the same process with two different labels remains unclear. To answer this question, the present study directly compared the influence of facial attractiveness on judgments of moral goodness and moral beauty and revealed distinct contributions of imaging perceptions to these two judgments. The results showed that in the moral beauty judgment task, participants gave higher scores to characters with attractive faces compared with characters with unattractive faces, and larger P200 and LPP were elicited in the unattractive-face condition compared with the attractive-face condition; while in the moral goodness judgment task, there was no significant difference between the two conditions of either behaviour or ERP data. These findings offer important insights into the understanding and comparison of the processes of moral judgment and aesthetic judgment.
