What Is the Dark Triad? Machiavellianism, Narcissism and Psychopathy
The Dark Triad is psychology's name for three socially aversive personality traits. Here is what each trait means, where the idea came from, and why everyone sits somewhere on these scales.

The Dark Triad is a group of three personality traits that psychologists study together because they share a common core: a tendency to put yourself first at other people’s expense. The three are Machiavellianism, narcissism and psychopathy.
Where the term came from
Psychologists Delroy Paulhus and Kevin Williams introduced the name in a 2002 paper titled “The Dark Triad of personality.” They noticed that the three traits overlapped, yet each also had its own character, and that ordinary people, not only clinical patients, showed them to different degrees.
That last point matters. Dark Triad research is about everyday, “subclinical” levels of these traits in the general population. A high score on a questionnaire is not a diagnosis of narcissistic personality disorder or of a psychopath in the clinical sense.
The three traits
Machiavellianism: the strategist
Named after Niccolò Machiavelli, the Renaissance author of The Prince, this trait describes a cool, calculating approach to people. Someone high in Machiavellianism plans ahead, keeps information close and is willing to manipulate when it pays off. Psychologists Richard Christie and Florence Geis built one of the first questionnaires for it, the Mach IV, in 1970.
Narcissism: the star
Named after Narcissus, the figure in Greek myth who fell in love with his own reflection, this trait centers on a need for admiration. People high in narcissism tend to feel special, seek attention and react badly to criticism. It is often the most outwardly charming of the three.
Psychopathy: the daredevil
In Dark Triad research, psychopathy means a combination of impulsivity, thrill-seeking and low empathy or guilt. People high in this trait act first and think later, and they are less bothered by other people’s distress. Of the three traits it is usually the most strongly linked to risky and antisocial behavior.
How the three differ
| Trait | Core drive | Typical style |
|---|---|---|
| Machiavellianism | Long-term advantage | Patient, strategic, manipulative when useful |
| Narcissism | Admiration and status | Confident, attention-seeking, sensitive to criticism |
| Psychopathy | Thrills and impulse | Bold, impulsive, callous |
How it is measured
The best-known short questionnaire is the Short Dark Triad (SD3), published by Daniel Jones and Delroy Paulhus in 2014, with 27 statements rated from disagree to agree. It produces a score for each of the three traits rather than a single “dark” label.
Is there a fourth?
Some researchers add everyday sadism, enjoying other people’s suffering, and call the set the Dark Tetrad. The extra trait is still debated, but it shows how the idea keeps evolving.
Everyone has a little
The traits are scales, not boxes. Almost everyone scores somewhere above zero, and moderate levels can even help in some settings: a dash of narcissism can fuel confidence on stage, and a little Machiavellian planning helps in a tough negotiation. Problems tend to appear when the traits are high and combined with little regard for others.
In short
The Dark Triad is Machiavellianism (strategic manipulation), narcissism (hunger for admiration) and psychopathy (impulsive, low empathy). They are everyday personality scales that everyone sits somewhere on, not diagnoses.
