We are simultaneously drawn to and repelled by sensationalized stories of serial killers and mass murderers, seeking to understand how one of our fellow humans could commit such atrocities against innocent victims. Are these offenders vastly different from us in their genes, early environment, and/or recent life stressors, or are we all capable of such cruelty under the right set of circumstances? We wonder about what dark aspects of the human personality might be involved in such horrific acts. The question of why people violate social norms, commit moral transgressions (e.g., deceit, manipulation), and inflict harm on others has long intrigued psychologists and the public alike.

The Dark Triad refers to three overlapping but distinct personality traits associated with a variety of antisocial and morally transgressive behaviors: psychopathy, narcissism, and Machiavelianism (Paulhus & Williams, 2002). Considered together, these traits involve emotional coldness, a lack of empathy, the desire for personal advancement at the expense of healthy relationships, grandiosity, and a willingness to manipulate others (Jonason, Lyons, Bethell, & Ross, 2013). Although there are well-known clinical manifestations of psychopathy and narcissism, work on the Dark Triad has emphasized the goal of understanding the subclinical forms of these traits found throughout the population (Furnham, Richards, & Paulhus, 2013). That is, most of the Dark Triad research seeks to understand the dark personalities we encounter in our daily lives.

Psychopathy

Psychopathy describes a specific constellation of affective, interpersonal, lifestyle, and behavioral characteristics. These include impulsivity; callous affect; poor reliability in performing various roles; a lack of remorse, empathy, or guilt; and a tendency toward rule violation (Hare, 2003; Jones & Paulhus, 2014). Although psychopathy is associated with criminality and violence (Hare & Neumann, 2009) and is considered to be the most dangerous of the Dark Triad traits, its utility is not restricted to criminal and forensic contexts. For example, subclinical psychopathy predicts a variety of behaviors that are not necessarily criminal (e.g., academic dishonesty, relational aggression, cyber aggression, substance misuse) but still likely to be of interest (Kokkinos, Antoniadou, & Markos, 2014; Williams, Paulhus, & Hare, 2007).

Narcissism

Much like the clinical version (i.e., Narcissistic Personality Disorder), subclinical narcissism involves grandiosity, as well as entitlement and a sense of superiority; however, this grandiose narcissism is only one part of the construct. Another important aspect involves narcissistic vulnerability, which refers to a vulnerable self-concept and efforts at self-enhancement (Morf & Rodenwalt, 2001). While grandiose narcissism tends to be emphasized in much of the Dark Triad literature, vulnerable narcissism appears to be relevant in many areas of emotional and interpersonal functioning. Subclinical narcissism has been linked to aggression (Bushman & Baumeister, 1998), online antisocial behavior (Carpenter, 2012), and a number of other variables of interest.

Machiavellianism

Machiavellianism is probably the least understood of the Dark Triad traits. It refers to a manipulative interpersonal style named for Niccolò Machiavelli (Christie & Geis, 1970). In The Prince (1513), Machiavelli described several behaviors most of us would regard as immoral (e.g., lying, deceit, and even murder) as effective strategies for a ruler to maintain power. Machiavellianism is perhaps best characterized as the perspective that the ends justify the means. People high in Machiavellian traits are described as cynical on morality, focused on personal gain, and willing to manipulate and exploit others to achieve their goals (Jones & Paulhus, 2009). Machiavellian personality traits have been linked to online relational aggression (Abell & Brewer, 2014) and a number of other antisocial behaviors.

At the Anger and Traffic Psychology Lab, our primary interest with regard to the Dark Triad traits involves their role in nonclinical populations (i.e., individuals in the community who are not currently receiving treatment for diagnosed personality disorders or other mental health problems) of emerging adults. That is, we are interested in how individual differences in scores on subclinical measures of Dark Triad traits relate to a variety of socially undesirable behaviors (e.g., overt and relational aggression, cyber aggression, dysfunctional anger expression, jealousy, academic dishonesty, aggressive driving) among young adults.
