We all have stories of meeting people who appeared wonderful at first but turned out to be just awful. Perhaps it was a charming suitor, or a charismatic colleague, or a fascinating new friend. They attracted you on initial impression, but before long, you started to notice behaviors that gave you pause. Maybe it was a little shading of the truth here and there, or a bit too much vanity and selfishness. Perhaps they constantly played the victim, or took credit for other people’s work.
Or maybe your disillusionment with the person was not gradual, but through a dramatic—and dramatically unpleasant—episode. All it may take is a minor disagreement, and suddenly, you get screamed at, threatened with retaliation, or reported to HR. This kind of encounter leaves you, understandably, baffled, hurt, and confused.
Very likely, this person was a “Dark Triad” personality. The term was coined by the psychologists Delroy Paulhus and Kevin Williams in 2002 for people with three salient personality characteristics: narcissism, Machiavellianism, and a measurable level of psychopathy. These people confuse and hurt you, because they act in a way that doesn’t seem to make sense. As one scholar aptly described the ones whose behavior shades more obviously into psychopathy, these are “social predators who charm, manipulate, and ruthlessly plow their way through life, leaving a broad trail of broken hearts, shattered expectations, and empty wallets.”
But at least these people are rare, right? Wrong. Dark Triads counted for about one in 14 people in an international population sample, a proportion that means all of us will meet them on a regular basis in love, in work, in politics, and—most obviously—on social media. For the sake of our happiness, well-being, and wallets, we need to understand them, learn how to identify them, and steer clear of them whenever we can—so that we can find better companions instead.
Narcissism is the egotistical admiration of oneself. Machiavellianism is a duplicitous interpersonal style and disregard for morality. These characteristics are bad enough, but the element of psychopathy adds in an absence of empathy and remorse to complete the Dark Triad: It’s all about me, I am willing to hurt you for my gain, and I don’t care how you feel.
Sometimes, a person like this will display a fourth trait to make a Dark Tetrad: sadism, or the enjoyment of others’ suffering. Some scholars have argued, in effect, that all triad types are really tetrads, because narcissism, Machiavellianism, and psychopathy are all expressions of a governing tendency toward sadism. But whether such personalities enjoy their predation or not is beside the point; with three traits or four, they make life miserable for the rest of us.
