6. The Dark Triad...

https://en.wikipedia.org/wiki/Dark_triad

The dark triad is a subject in psychology that focuses on three personality traits: narcissism, Machiavellianism, and psychopathy.[1][2][3][4] Use of the term "dark" implies that people possessing these traits have malevolent qualities.[5][6][7][8]

Research on the dark triad is used in applied psychology, especially within the fields of law enforcement, clinical psychology and business management. People scoring high on these traits are more likely to commit crimes, cause social distress and create severe problems for an organization, especially if they are in leadership positions (for more information, see psychopathy, narcissism, and Machiavellianism in the workplace).

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.[9]

Narcissism is characterized by grandiosity, pride, egotism, and a lack of empathy.[10]
Machiavellianism is characterized by manipulation and exploitation of others, a cynical disregard for morality, and a focus on self-interest and deception.[11]
Psychopathy is characterized by enduring antisocial behavior, impulsivity, selfishness, callousness, and remorselessness.[12]
A factor analysis carried out at the Glasgow Caledonian University 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.[11]
