Dark Triad of Personality
Also known as: Dark Triad · SD3 framework
Framework grouping three socially aversive but subclinical personality traits that had been studied separately: machiavellianism (a strategic, manipulative approach to people), narcissism (grandiosity and a need for admiration) and psychopathy (impulsivity combined with low empathy and remorse). Paulhus and Williams (2002) showed the three overlap without collapsing into one another, which is what makes them worth measuring together. Jones and Paulhus (2014) later built a brief measure with equal coverage of the three, the operationalisation this catalog's adaptation follows. The traits are dimensional and subclinical: everyone sits somewhere on all three, high scores describe a trade rather than a disorder, and research has argued that what they share is, in mirror image, the Honesty-Humility factor of the HEXACO model.

Constructs
Machiavellianism
A strategic, calculating orientation toward other people: planning ahead, managing what others know, choosing alliances for what they yield, and waiting for the right moment (Christie & Geis, 1970; measured alongside the other two traits by Jones & Paulhus, 2014). The dimension describes patience and manipulation together, which is why it predicts success in negotiation and a slow erosion of the trust that cannot be strategized into existence. It is subclinical: everyone sits somewhere on it.
Narcissism
Grandiosity, a sense of being special, and a running need for admiration (Raskin & Hall, 1979; measured alongside the other two traits by Jones & Paulhus, 2014). Confidence recruits attention and attention feeds confidence, which is part of why the trait persists; the exposure is the dependence on the mirror, since criticism or someone else's turn in the light registers as injury. The subclinical trait measured here is not narcissistic personality disorder, which is a clinical diagnosis made by a professional through interview.
Psychopathy
Impulsivity and thrill seeking combined with low empathy and little remorse (Hare's tradition, in the subclinical operationalisation of Jones & Paulhus, 2014). Of the three, it is the one most consistently linked to the harshest outcomes, and also the one that reads as composure in a crisis. The score describes where impulse and distance are doing the deciding, on a dimension the general population varies along; it is not a forensic finding and not a clinical category.
Sadism
Everyday sadism: finding other people's suffering appealing rather than merely tolerable (Buckels, Jones & Paulhus, 2013; added to the dark traits as the fourth member by Paulhus, 2014). The distinction from psychopathy is about reward and not about severity, in the source article's own words: where psychopathy is indifferent to suffering, sadism finds it attractive. In the subclinical population where it is studied, most of what the construct picks up is vicarious, an appetite for watching conflict in sport, in fiction and in games, together with a taste for cutting remarks. It is a continuous dimension of ordinary personality, not a diagnosis and not a forensic category, and research on subclinical samples has found little sign of psychological dysfunction attached to it.
