Differences in dark triad personality: Evidence from China and the USA

The main purpose of this study aims to compare the scale level average scores of Dark Triad personality in China and the USA, as well as the correlation differences between three subscales of dark personality. The present study examined Dark Triad personality perceptions, and three big adult samples are selected in China and the USA separately (N-1 = 507, N-2 = 925, N-3 = 1251). They all finished the Short Dark Triad (SD3) personality scale in paper-pencil or online format. Descriptive statistics of two comparison samples are presented. We took classical NHST and Bayesian method to test the cultural differences on scale scores. In Bayesian statistics, the results are relatively reliable. There are significant differences between China and the USA samples on narcissism and psychopathy, East get higher scores. China participants get lower scores than the USA on Machiavellianism. For the intercorrelations of subscales, some values and patterns are different significantly. Moreover, the results should be replicated in more research. The limitations and future directions of the present study also be discussed at the end of the study.
