The Dark Triad and risk behavior

The Dark Triad traits—Machiavellianism, narcissism, and psychopathy—are theorized to facilitate short-term, exploitative social tactics. Thus, the Dark Triad traits should be positively related to (a) similar short-term-focused traits such as impulsivity and sensation-seeking, and (b) risky behaviors. In two studies (N > 1400), we examined the relationships among the Dark Triad traits and impulsivity and sensation-seeking. In Study 2, we incorporated risk behaviors, including blackjack betting and temporal discounting of money. Both studies showed positive relationships among the Dark Triad traits and impulsivity and sensation-seeking. Study 2 showed positive relationships among the Dark Triad traits, blackjack betting, and steeper temporal discounting. An experimentally manipulated ego threat in Study 2 marginally moderated the narcissism–discounting relationship; ego-threatened participants had a significantly positive relationship, whereas those who were not threatened showed no relationship. We discuss implications of the Dark Triad traits for understanding risk behavior.

► The Dark Triad traits are positively related to impulsivity and sensation-seeking.
► The Dark Triad traits are positively related to blackjack betting.
► The Dark Triad traits are positively related to steeper temporal discounting.
► Ego-threat resulted in a positive narcissism–discounting relationship.
► Those with no ego-threat showed no narcissism–discounting relationship.
