Dark Triad Personality Test

This is interactive version of the Short Dark Triad (SD-3), which measures the three traits of machiavellianism, narcissism, and psychopathy.


The dark triad personality traits are three closely related yet independent personality traits that all have a somewhat malevolent connotation. The three traits are machiavellianism (a manipulative attitude), narcissism (excessive self-love), and psychopathy (lack of empathy). The dark triad has traditionally been assessed with three tests different tests, each of which had been developed individually. Most commonly, the Narcissistic Personality Inventory (NPI) was used as the measure of narcissism, the MACH-IV for machiavellianism and the Self-Report Psychopathy Scale (SRP) for psychopathy. Format differences between these (multiple choice versus scale rating) complicated administration and analysis. The Short Dark Triad was developed in 2011 by Delroy Paulhus and Daniel Jones to provide a more uniform assessment and also to trim down the total length.
