The Dark Triad

Welcome to Mind Tools' Video Learning Series.

We've all come up against unsavory behavior at times. Perhaps you've had to work with someone who's volatile, arrogant or domineering.

Such traits can have a destructive effect on both you and your team. But, with careful management, you can neutralize these unsavory elements and restore team harmony.

There are three main personality traits that psychologists have identified as being especially toxic. These are: psychopathy, Machiavellianism, and narcissism, and together they are known as the "Dark Triad."

People with psychopathic traits tend to be antisocial, volatile, and unable to express remorse.

While people with Machiavellian characteristics can be two-faced. They're manipulative and lack morality.

Meanwhile, narcissists have an excessive interest in themselves. They come across as selfish, arrogant, and they lack empathy.

People are often very good at hiding these "dark" behaviors, which can make it hard to assess their true nature. However, experienced observers can use the "Dirty Dozen" rating scale to identify such personalities.

To learn more about the rating scale, read the article that accompanies this video.

So, what can you do to guard against these "dark" behaviors, and to manage them effectively?

People with psychopathic traits are often prone to anger or aggression, so make it a priority to stay safe. Defuse the situation by keeping your distance. Leave the room if you need to. And stay in control of your own emotions.

If such behavior spills over into bullying, respond by supporting the victim and confronting the bully. And be sure to hold him or her accountable.

If someone has Machiavellian tendencies, she'll likely be a master manipulator. This means she's good at hiding her true self. She'll be unable to take "no" for answer and she'll use excuses to justify hurtful comments that she makes.

If you need to challenge her behavior, be specific about how it's affecting the team. Make it clear that her attitude needs to change, and use performance reviews that are based on a sound body of evidence to monitor this.

Finally, if it's a narcissist you're dealing with, nip his behavior in the bud quickly.

The self-centeredness of narcissists means they often don't realize the impact of their behavior. They also tend to grab the spotlight, dominate conversations, and demand credit for ideas.

People like this don't expect to be challenged, so stand your ground. Or, put them in a situation where they need to work with their colleagues. This will help to increase respect and understanding within your team.
