About the Dark Tetrad Test
The Dark Tetrad is a psychological framework that expands upon the well-known "Dark Triad" of personality traits. While the original Triad focuses on Machiavellianism, Narcissism, and Psychopathy, the Tetrad introduces a fourth, distinctly malevolent dimension: Everyday Sadism.
The Four Dimensions
1. Machiavellianism
Characterized by a duplicitous interpersonal style, cynical disregard for morality, and a focus on self-interest and personal gain. Named after the philosophy of Niccolò Machiavelli, individuals high in this trait are strategic, calculating, and master manipulators.
2. Narcissism
Defined by grandiosity, pride, egotism, and a lack of empathy. Narcissists harbor a deep-seated belief in their own superiority and entitlement, constantly seeking validation, admiration, and attention from those around them.
3. Psychopathy
Marked by profound deficits in emotional functioning, specifically shallow affect, callousness, and an utter lack of remorse or guilt. Psychopaths are often impulsive, thrill-seeking, and entirely indifferent to the suffering they cause others.
4. Everyday Sadism
The newest addition to the dark cluster. It involves experiencing intrinsic pleasure, excitement, or satisfaction from inflicting or observing physical or psychological pain and humiliation in others, even in mundane contexts (e.g., internet trolling, cruelty to animals, or malicious workplace behavior).
Test Methodology & Validity
This website's test items are independently authored and are not affiliated with IDR Labs or the SD3™ scale. This assessment uses items adapted from the empirical research into the Dirty Dozen scale (Jonason & Webster, 2010, Psychological Assessment) combined with publicly available research into the manifestation of subclinical sadism.
Dark Triad vs. Dark Tetrad
The original Dark Triad — Machiavellianism, Narcissism, and Psychopathy — was introduced by Paulhus & Williams in 2002. Research by Buckels, Jones, and Paulhus subsequently established that Everyday Sadism is a statistically distinct fourth dimension not reducible to the other three. The resulting Dark Tetrad provides a more complete model of socially aversive personality. Learn more in our full comparison of the Dark Triad vs Dark Tetrad.
