Potential ‘‘darker sides’’ of socio-emotional intelligence (SEI) have been repeatedly noted. We examine whether SEI is associated with emotional manipulation of others when used by dark personalities (Dark Triad: narcissism, Machiavellianism, psychopathy). In N = 594 participants, narcissism was positively, Machiavellianism negatively, and psychopathy positively and negatively associated with SEI. Moreover, narcissism and psychopathy moderated links between facets of emotional intelligence and emotional manipulation. Findings are discussed in context of a ‘‘dark intelligence’’ used for malicious intents.
