The dark triad is a psychological theory of personality, first published by Delroy L. Paulhus and Kevin M. Williams in 2002, that describes three notably offensive, but non-pathological personality types: Machiavellianism, sub-clinical narcissism, and sub-clinical psychopathy. Each of these personality types is called dark because each is considered to contain malevolent qualities.All three dark triad traits are conceptually distinct although empirical evidence shows them to be overlapping. They are associated with a callous–manipulative interpersonal style.
Narcissism is characterized by grandiosity, pride, egotism, and a lack of empathy.
Machiavellianism is characterized by manipulation and exploitation of others, indifference to morality, lack of empathy, and a strategic focus on self-interest.
Psychopathy is characterized by continuous antisocial behavior, impulsivity, selfishness, callous and unemotional traits (CU), and remorselessness.High scores in these traits have been found to statistically increase a person's likelihood to commit crimes, cause social distress, and create severe problems for organizations, especially if they are in leadership positions. They also tend to be less compassionate, agreeable, empathetic, and satisfied with their lives, and less likely to believe they and others are good.A factor analysis found that among the big five personality traits, low agreeableness is the strongest correlate of the dark triad, while neuroticism and a lack of conscientiousness were associated with some of the dark triad members. Research indicates that there is a consistent association between changes in agreeableness and the dark triad traits over the course of an individual's life.
