This research explores the Dark Triad traits in 18 cultures from Europe, America, Africa, and Asia. We examined the relationships among Dark Triad traits, as measured by the SD3, with
gender, age, social status, and two personality models, HEXACO and Zuckerman’s alternative five factor model (AFFM). There were 10,298 participants (5,410 women and 4,888 men) with
a mean age of 40.31 (SD =17.32) years old. Between 6% and 16% of the variance in the Dark Triad traits was accounted by culture. Men scored higher than women on all three traits in most
cultures, but gender differences were generally larger in European countries. The relationship between the Dark Triad traits dimensions and age is negative, but the largest effect size is small (Psychopathy; η 2 =.018). Psychopathy is associated with low Social Position, and Narcissism with high Social Position. In regard to Personality traits, Narcissism is positively related to Extraversion, and Psychopathy is negatively related to Conscientiousness for the HEXACO, and Narcissism is positively related to Activity and Sensation Seeking, and Machiavellianism and Psychopathy are positively related to Aggressiveness and Sensation Seeking for the AFFM.
