Background
The Short Dark Triad Personality Test (SD3-41) is the interactive version of the Short Dark Triad (SD3) 41-items personality assessment developed by Jones and Paulhus to measure three distinct but related personality traits known as the Dark Triad: Machiavellianism, Narcissism, and Psychopathy.
(SD3) is widely used self-assessment to measure the dark side of personality based on three interrelated and socially unacceptable traits psychopathy, Machiavellianism, and narcissism. The scale helps you understand how these dark personality traits may influence your decision-making, relationships and ambitions. Modern psychology believes that most people possess at least some degree of these traits.
Machiavellianism: Machiavellianism is a famous word in psychology named after a 16th-century political philosopher Niccolò Machiavelli, famous for his book “the prince”. The main message in the book is that leaders can use Manipulate, Deceit, and explicit behavior to strive for power and position and it is the necessity to maintain the power and accomplish that goals.
Narcissism: Narcissism is a personal trait in which an individual has an extreme sense of self-importance and a constant urge for administration resulting in ignoring the needs of others and a lack of empathy. The good example may be a person who feels uncomfortable in the situations where he/she is not the center of attention and who is always talking about the prestige or status. Take the narcissistic personality disorder test.
Psychopathy: Psychopathy is described as having a lack of remorse, being callous and cynical. Psychopathy exists on a spectrum and not everyone with psychopathic traits meets the diagnostic criteria for antisocial personality disorder. You may also like to take the psychopathy spectrum scale.
Although the three dimensions share certain interpersonal characteristics, research consistently demonstrates that Machiavellianism, Narcissism, and Psychopathy are distinct personality constructs with different emotional, motivational, and behavioral patterns.
Procedure
The assessment consists of 41 statements and typically takes 4–7 minutes to complete. Participants respond to statements describing beliefs, attitudes, interpersonal behaviors, emotional tendencies, and personality characteristics associated with Machiavellianism, Narcissism, and Psychopathy.
Participation
This assessment is intended for adults and older adolescents interested in understanding personality characteristics associated with manipulation, strategic thinking, self-enhancement, entitlement, impulsivity, emotional detachment, and interpersonal behavior. Participation in this online assessment is completely anonymous. No personally identifying information is collected or stored.
Scoring & Interpretation
The assessment contains 41 items rated on a five-point agreement scale ranging from Strongly Disagree (0) to Strongly Agree (4).
The scale includes both forward-scored and reverse-scored items. Reverse-scored items are automatically adjusted before calculating results.
Item responses are calculated to produce a raw total score ranging from 0 to 164, with higher scores indicating stronger expressions of Dark Triad personality characteristics.
Dimension and overall results are classified into five interpretive ranges:
• Reserved (0–20)
• Balanced (21–40)
• Developed (41–60)
• Strong (61–80)
• Exceptional (81–100)
Higher scores reflect greater tendencies toward strategic manipulation, self-enhancement, entitlement, emotional detachment, impulsivity, and exploitative interpersonal behavior.
