Exploring cultural and gender differences in moral judgment: A cross-cultural study based on the CNI model

Recently, researchers have proposed a polynomial model called the “consequences, norms, generalized inaction” (CNI) model for researching moral judgment. However, it is unclear whether the model can be used to explore cultural differences in moral judgment. In this study, we investigated the applicability of the CNI model of moral judgment to East Asian groups, and subsequently explored cultural and gender differences in moral judgment between East Asian (i.e., Japan, n = 211; China, n = 200) and Western (i.e., USA, n = 201) groups. The CNI model was proposed by Gawronski et al., and it can quantify individuals’ sensitivity to moral consequence, sensitivity to moral norms, and their general preference for inaction or action in moral dilemmas. Our results indicate that the CNI model fits well for Japanese and Chinese individuals. Both East Asian women and Western women were significantly more sensitive to moral norms than men in their respective countries. In the international comparison, Westerners were more sensitive to moral norms. The Japanese groups, for both men and women, were most biased towards inaction. Regarding sensitivity towards consequences, no differences were observed in the comparison between Eastern and Western male groups, whereas poor sensitivity was observed among women. By using this new model, this study provides new insights into the differences of cultural and gender in moral judgment.
