The Dark Triad of Personality Types

The Dark Triad is a phrase used to describe three similar yet independent personality traits: Machiavellianism (manipulative), Narcissism (self-love) and Psychopathy (lack of empathy). These traits are held to be fairly common in work and fairly malevolent.

The Dark Triad

The Dark Triad, the three traits of Machiavellianism, Narcissism and Psychopathy, are considered to be fairly prevalent in the world of work. Researchers have linked these behavioral traits with the process of acquiring of leadership, and the dark triad has been found to be particularly highly represented in more senior roles, including the C-suite. In fact, some researchers have put the proportion of CEOs with clinically significant levels of psychopathic traits as high as 20%.

By understanding these personality traits it may be possible for individuals to develop their own self awareness or learn more about working with others, particularly those who embody these traits.

While individuals who have these traits will probably not want to change them (or perhaps not be able to), it’s still useful for everyone to learn about them.

It’s worth noting that there is a correlation between low levels of “agreeableness” per the Big Five personality test and these negative traits. These traits also embody almost the inverse of what is known as Authentic Leadership.


Machiavellianism derives its name from the renaissance diplomat and author, Niccolò Machiavelli, who is most well known for his book “The Prince“.

In “The Prince“, Machiavelli described and even promoted the use of unethical and undesirable behavior as a means to acquiring or maintaining power. Perhaps the most famous quote from “The Prince” is “It is better to be feared than loved, if you cannot be both“.

He looks pretty cunning here…

Machiavellianism at work manifests through cunning, duplicity and self-serving behavior. Modern thinking on Machiavellianism in the workplace focuses on three factors: maintaining power, harsh management and manipulative behaviors.

Where Machiavellians exist in work they create counterproductive workplaces, may bully others and are often dishonest in pursuit of their personal goals. They may present arrogantly, will never show humility, will withhold important information or will spread falls rumors to succeed. Unfortunately, they are also often skilled liars and can be charming, the combination of which can make them difficult to spot.

Fundamentally, Machiavellians are more interested in their own outcomes than those of others, and will work towards their own goals at the expense of others. To work well with them, you might need to make sure that you are useful in helping them achieve their goals and that you don’t become a threat to them and their power.


Narcissism derives its name from Narcissus, a figure of Greek mythology. According to legend, Narcissus became so enamored with his own reflection that he ultimately couldn’t move and transformed into a flower (the Narcissus, commonly know as the Daffodil).

I wandered lonely as a cloud…

Workplace narcissists, like Narcissus, have an excessive interest in and admiration of themselves. They often present well initially, and interview well (saying how good they are comes naturally to them), but these first impressions don’t last. In the longer term they are high detrimental in the work place.

Narcissists generally rate their own performance very highly, struggle to value to the contributions of others, focus nearly exclusively on themselves, and seek frequent flattery, reward and attention. This is toxic in leadership as they often punish individuals who don’t feed their egos. There tend to be higher levels of stress related absence around narcissists. 

Mirror, mirror on the wall.

At their core Narcissists are focused on themselves, their sense of importance and their own, personal brilliance. To work well with a narcissist can be easy, you simply need to tell them they are great and never let them know what you really think. In practice, bending yourself out of shape to do this might be more emotional effort than it’s worth to stay on side with a narcissist.


Psychopathy is a term that was coined in the 19th century. It’s a combination of “psych”, meaning mind or soul, and pathology, meaning disease. In other words, it directly simply means “diseased mind”, a rather unspecific phrase.

Workplace psychopaths lack empathy and remorse, are disinhibited and are often egotistical. They crave power, are drawn to leadership and are over-represented in senior corporate roles. They often ”kiss up and kick down”, being charming to their bosses but abusive to those beneath them.

Despite their negative traits, psychopaths can also be charming, witty, intelligent, and often come across as sincere. Their charm, though, is only skin deep and often simply a means through which they strive to achieve their own ends.

Psychopaths can be charming, warm, engaging and friendly, when it suits them.

Interestingly, psychopaths often thrive under abusive cultures as they generally need less positivity in their relations and experience stress less than others. What this means is that psychopathic leaders can create environments in which only other psychopaths really prosper, building a lasting, heritable stain on their organization’s culture.

Working well with psychopaths can be challenging. To have the best chance of successfully doing so, keep your emotions in check no matter what happens, don’t show that you’re intimidated, don’t trust or believe what they say, try and keep conversations focused on them and where possible communicate in writing. Simple!

These traits are not pleasant to be around and you should avoid leaders who embody these traits. They cause stress, ill-health, reductions in productivity and sometimes mental health difficulties.

Unfortunately, they are also traits that many leaders have. Leaders cast long shadows and leaders with these traits often create unpleasant cultures. If you are working with people with these traits, there are techniques that you can adopt to cope with them, but people with these traits seldom change.

The best thing you can do in relation to people who have these traits is to not employ them in the first place. Of course, this isn’t always possible as they often present well. Removing them from your organization is the next best thing to do. Though it may be painful and expensive to do so, it’s usually more than worth it in the long run. If you’ve hired them and can’t get rid of them, then you’ll simple need to spend time managing the negative fallout that they create within and around their teams.

It’s worth noting that there are clinical levels of these personality types and sub-clinical levels. Where you draw the line between normal behaviors and these behaviors will determine how prevalent you find these behaviors to be. In our view, there is some exaggeration of the prevalence of these traits in the workplace in some articles.
