Why People With High Alexithymia Make More Utilitarian Judgments.

Abstract

Although recent studies have investigated the effect of alexithymia on moral judgments, such an effect remains elusive. Furthermore, moral judgments have been conflated with the moral inclinations underlying those judgments in previous studies. Using a process dissociation approach to independently quantify the strength of utilitarian and deontological inclinations, the present study investigated the effect of alexithymia on moral judgments. We found that deontological inclinations were significantly lower in the high alexithymia group than in the low alexithymia group, whereas the difference in the utilitarian inclinations between the two groups was nonsignificant. Furthermore, empathic concern and deontological inclinations mediated the association between alexithymia and conventional relative judgments (i.e., more utilitarian judgments over deontological judgments), showing that people with high alexithymia have low empathic concern, which, in turn, decreases deontological inclinations and contributes to conventional relative judgments. These findings underscore the importance of empathy and deontological inclinations in moral judgments and indicate that individuals with high alexithymia make more utilitarian judgments over deontological judgments possibly due to a deficit in affective processing.
