 In psychology, the dark triad represents three personality traits – narcissism, psychopathy, and Machiavellianism. If we were to ask the three who has the darkest personality, the narcissist would say me, the psychopath would say I don't care, and the Machiavellian would say it's whoever I want it to be. People scoring high on the three traits are more likely to commit crimes and create severe social problems in society, families, and organizations. This is why the research on the dark triad is used widely in law enforcement, psychology, and business. Here is an overview of what we know. The narcissist displays grandiosity, entitlement, and superiority and wants nothing more than admiration. Once he gets what he wants, the narcissist is rarely interested in other people. When he does care, it's to enhance his status, which is why he likes to mingle with successful others. They seem as though they're completely in love with themselves, but at the root of their inflated egos are often deeply held feelings of inferiority. To protect their constructed self, they can never admit to being wrong, which is why they lie or blame others. Machiavellians are unprincipled, cold, and have a cynical view of other human beings. They like money, power, and winning, and they use manipulation to get what they want or exploit others. If manipulation doesn't work, they steal or betray. Those high on the spectrum believe it's better to be feared than being liked and offend others as a strategy to control them. When you are a psychopath, you come across as cold and others think you are scary. You also show little to no fear, act impulsively, and you enjoy mental thrills. Those high on the spectrum don't form any emotional bonds. The result is a complete lack of compassion. That means they have no problem being mean. If something terrible happens, they later often don't feel any remorse or guilt. The research tells us that men score significantly higher on all three compared to women, and while these three personalities are empirically distinct, they do overlap. Clinically, both narcissism and psychopathy are regarded as mental disorders, while Machiavellianism isn't. Whether nature or nurture is responsible for these traits has been somewhat answered by twin studies that show that narcissism and psychopathy have substantial genetic components. Machiavellianism seems to be less prevalent in pairs of twins. However, the environment also matters. A psychopath may not only pass down his genes, but influence a child by being a role model. A Machiavellian father shares with his son not only genetic material, but might also show him all his tricks. The son of a narcissist not only gets his dad's chromosomes, but may also experience his perfectionism. With the big five personality traits, also known as ocean, the three correlate either positively or negatively. Narcissists and psychopaths are often open to new ideas and extroverted. Psychopaths and Machiavellians have low conscientiousness. All three personality types score low on agreeableness. And psychopaths are hardly neurotic. Whatever happens, leaves them cold. An evolutionary explanation for these traits could be sexual strategy. Many of us pursue a slow life, invest in long-term relationships, have a few children and spend time on parenting. Dark triad traits may have survived because they look to optimize a fast life. Their ancestors lived in an unpredictable and dangerous world. Because of a shorter life, they sought many sexual partners, spent no time on parenting and did not invest in human relationships. This may also explain why they strive in competitive environments, such as corporations. Here, a Machiavellian may use charm and insults to manipulate others. The narcissist is physical appearance and a psychopath, physical threats. And since they all lack compassion, they often elbow their way to the top, which is maybe why all three dark traits are well represented in upper-level management. But there are also downsides. If your mind was programmed to be impulsive, aggressive and selfish, you are also more likely to abuse drugs, feel excluded, suffer from depression or end up in jail. This is why we may not only find ways to protect ourselves from these darker minds, but also have empathy for them. After all, maybe they didn't choose to be that way. What about you? Did you inherit some dark triad traits? And if that's the case, and if you are aware of them, did you develop strategies to cope with them?
