Dark triad · SD3

The full dark triad questionnaire

Twenty-seven statements about how you deal with other people. For each one, tap how much you agree. At the end you get a reading across the three traits the scale measures.

This is the Short Dark Triad (SD3) by Jones and Paulhus, which measures three socially aversive but normal-range traits: Machiavellianism, narcissism, and psychopathy. It scores these as everyday personality dimensions on a spectrum, not as clinical disorders. A high score is a prompt for reflection, not a verdict.
