The study aimed at examining three issues. Firstly, the relation of personality and career success was to be illuminated. Secondly, in the context of the bandwidth-fidelity-discussion, it should be decided whether the concept of the Dark Triad, representing fine-grained and narrow traits, is able to add incremental validity over broader personality variables, such as the Big Five or the HEXACO-Model of personality. Thirdly, the moderating effects of job autonomy, frequency of communication, and job tenure on the relation of dark traits and career success were tested. 291 subjects (152 females, Mage=37.67, SDage=10.38) completed an online survey. Salary, hierarchical position and in case of managerial responsibility, number of staff responsible for, served as criteria for objective career success. Job satisfaction, affective commitment and self-rated performance were used as indicators for subjective career success. Hierarchical linear regressions and correlation analyses showed that personality traits explain more variance of subjective than objective career success. Age and gender predict objective success better than personality. Concerning subjective success, it seems to be the other way round. Agreeableness was positively linked to subjective and negatively related to objective criteria of success, whereas neuroticism correlated negatively with both. Extraversion and conscientiousness were positively related to subjective and objective criteria. Regarding the dark traits, narcissism correlated positively with both, objective and subjective career success. Negative correlations could be detected for subclinical psychopathy and subjective career success. The dark triad added incremental validity for income and self-rated performance. Job tenure moderated the relation of narcissism and salary in a positive way. Additionally, the factor structure of the NPI was examined. A solution, containing grandiosity, dominance and exhibitionism fitted best in form and content.
