Manipulative? Grandiose? Cold-hearted? The Dark Triad captures three socially aversive personality traits - Machiavellianism, Narcissism, and Psychopathy - in just 12 questions. Based on the Dirty Dozen scale (Jonason & Webster, 2010). Takes about 3 minutes.

What Is the Dark Triad (Dirty Dozen)?

The Dark Triad bundles three socially unpleasant personality traits: Machiavellianism (strategic manipulation), Narcissism (inflated self-importance), and Psychopathy (callousness and impulsivity). They overlap but are distinct enough to measure separately.

The Dirty Dozen (Jonason & Webster, 2010) gets you all three with just 12 items — 4 per trait. It takes about 3 minutes.

How Scoring Works

There are no clinical cutoffs — this is a research tool, not a diagnosis.

Reliability

  • Internal consistency: alpha = .83-.87 per trait
  • Test-retest: .87 at 3 weeks
  • Correlates well with longer measures like the full Dark Triad measures
> This is a research instrument, not a clinical diagnostic tool. High scores don't mean you have a disorder.
