How Dark Is Your Personality?
Three traits everyone has a little of, measured separately
In 2002 two researchers noticed that three traits with a bad reputation - wanting to be admired, being willing to manipulate, and not being much moved by other people's feelings - kept turning up together, and gave the cluster a name that stuck. What the name hides is that these are ordinary traits on a continuum. Everybody scores somewhere on all three, most people score low, and the interesting information is not whether you have them but which one is highest, because they lead to completely different behaviour.
Before you start There are no right answers. Pick what is usually true for you, not what sounds best.
Answer honestly - the questions are blunt on purpose, and nobody scores zero. A middling result is the normal one.
What it measures
The three traits of the Dark Triad as measured by the Short Dark Triad: narcissism, the need to be admired; Machiavellianism, the willingness to use strategy and people to get what you want; and psychopathy, a low reaction to other people's distress combined with impulsiveness. They overlap but are distinct, and the differences are the useful part.

Possible results
Needing admiration
Narcissism: being seen as special.
Playing the long game
Machiavellianism: strategy over sincerity.
Not much moved
Psychopathy: low reaction to others' distress, plus impulse.
Common questions
Does a high score mean I am a bad person?
No, and the framing is worth resisting. These are traits, not verdicts, and each has a version that works: the need for admiration drives people to achieve, strategic thinking is useful in any negotiation, and a thick skin is an asset in a great many jobs. What the research links to harm is not the trait but what it is paired with - ambition without empathy, strategy without honesty, impulse without a brake. The useful question is not whether you have the trait but what you have alongside it.
Why do these three go together?
That is the question the field has argued about for twenty years. The original proposal was that they are distinct traits that happen to correlate. A strong later view is that they share a single core - a low concern for other people - and differ in what is layered on top: grandiosity for narcissism, strategy for Machiavellianism, impulse for psychopathy. The practical reading is the same either way: the shared part is what makes any of them costly, and the differences are what determine how it shows.

An honest note Three things need saying plainly. First, this is not a clinical instrument and cannot say anything about narcissistic personality disorder or psychopathy as a diagnosis - the traits measured here are the everyday versions found across the general population, and a high score means high relative to other ordinary people, not anything clinical. Second, this is a short adaptation of the Short Dark Triad, which itself has been criticised: a 2025 review questioned how well its subscales separate and whether the psychopathy items capture the construct, and the three traits overlap enough that some researchers argue they share a single core of callousness. Third, these are the traits people are least honest about, in both directions - some under-report because the items sound bad, and some over-report because the label sounds edgy. If a result here worries you, the thing that matters is not the score but whether your behaviour is costing the people around you, and they are better placed than a questionnaire to tell you.
