“…Machiavellianism is a personality trait exemplified by the cynical ''cool syndrome'' (Christie and Geis 1970), which suggests a calculating rationality little influenced by emotions, interpersonal attachments, empathy, or altruism (Carnahan and McFarland 2007;De Corte et al 2007;Locke and Christensen 2007;Wastell and Booth 2003), and thus questionable ethics. Machiavellians seem inclined to be disagreeable (Elfenbein et al 2008), mistrusting (Sakalaki and Richardson et al 2007), not conscientious (Schlenker 2008 , Table S1), uncooperative (Paal and Bereczkei 2007), emotionally manipulative (Austin et al 2007), exploitive in relationships (Mullins and Kopelman 1988), and have been observed to lie, cheat, and bend rules for personal advantage (e.g., Kashy and DePaulo 1996;McLeod and Genereux 2008;Schlenker 2008).…”
