The Dark Triad — Machiavellianism, narcissism and psychopathy in everyday life
The Dark Triad describes three dark personality traits: Machiavellianism, narcissism and psychopathy. Learn how they differ, how to recognise them, and what the latest research says.
What is the Dark Triad?
The "Dark Triad" concept was introduced by Paulhus and Williams in 2002, describing three personality traits that — while distinct — often co-occur and are associated with behaviours harmful to others:
1. Machiavellianism — strategic manipulation, cynicism, lack of moral scruples in pursuit of goals 2. Narcissism — inflated self-view, need for admiration, sense of uniqueness 3. Psychopathy — low empathy, impulsivity, tendency toward antisocial behaviour
Critically, the Dark Triad describes personality dimensions, not diagnostic categories. Everyone has some level of each trait — problems emerge at extreme levels.
The SD3 Scale
The Short Dark Triad (SD3) by Jones & Paulhus (2014) is the most cited Dark Triad measurement tool. 27 questions (9 per trait), results on a 1–5 scale.
Research on tens of thousands of participants shows that: men score higher on average across all three traits; scores decrease with age; narcissism is most strongly linked to career success; psychopathy correlates most with destructive behaviour.
Remember: Dark Triad scores are just one facet of personality. A high score doesn't make you a "bad person" — it means awareness of these tendencies is valuable.
