Bad guys perform better? The incremental predictive validity of the Dark Tetrad over Big Five and Honesty Humility
Abstract This study analyzed incremental effects of the Dark Tetrad traits (i.e. narcissism, Machiavellianism, psychopathy, sadism) on job performance dimensions (i.e. task performance, contextual performance, counterproductive work behavior) over the Big Five and Honesty Humility. Using a multi occupational sample of 613 employees, results revealed positive outcomes depending on the specific Dark Tetrad trait analyzed. After including sociodemographic and work related variables, Big Five, and Honesty Humility, narcissism and Machiavellianism were positively related to task performance, whereas psychopathy and sadism were negative predictors. Narcissism was also a positive predictor of contextual performance, while sadism was positively related to counterproductive work behavior. These results show that the Dark Tetrad is useful in its own right and incrementally above normal range personality measures.
