No matter what the profession, if a boss has this personality combination, they are terrifying. The Dark Tetrad is composed of four parts: narcissism, Machiavellianism, psychopathy, and sadism. Sadism is the addition to the Dark Triad which has narcissism, Machiavellianism and psychopathy. For either condition, this means a person possesses the characteristics of all of these personalities.

The Dark Tetrad shares two major characteristics: extreme selfishness and a lack of empathy for others. This combination affords the ability to cause harm and abuse others in a variety of ways without any regard for the feelings, safety, or morality of the victims. As bosses, they are focused on dominance and power often using aggression, manipulation, exploitation, and vindictiveness. All behavior is justified if it grants them what they want, including criminal acts.

Narcissism. Narcissistic Personality Disorder is a DSM-V diagnosis. Generally speaking, they are superior, grandiose, demanding, prideful, boastful, arrogant, and self-centered. They need and expect constant admiration, attention, and affection. They can be abusive when threatened or their needs aren’t being met. The disorder is both inherited and developed in childhood.

Machiavellianism. Prince Machiavelli wrote the Italian book The Prince in the 1500s. It outlines a political philosophy on how rulers are to govern their subjects. Machiavellianism is the adaptation of this philosophy into a personality and as such is a personality construct not a disorder. Therefore, it is not inherited; rather it is a learned behavioral pattern. Machiavellians are manipulative, exploitative of others, cynical, deceptive and believe it is better to be feared than loved. Unlike Narcissists, they do not make exaggerated claims about their significance or accomplishments. Unlike Psychopaths and Sadists, they are too calculating to risk vengeful or cruel behavior unless there is a specific gain.

Psychopathy. Psychopaths are under the Anti-Social Personality Disorder umbrella listed in the DSM-V along with Sociopaths and Sadists. A psychopath has the ability to create an entire persona in direct contrast to who they really are. They are very calculating, callous, without a conscience, pathological liars, remorse-free, and dangerous. Their personality is both inherited and developed through a traumatic and abusive childhood. Psychopaths, unlike Machiavellians and Narcissists, can instantly read the emotions of others and calculate how to use it to their advantage without any emotional response. They have no problem hurting others, but it is always for a purpose, unlike Sadists.

Sadism. Sadists are a part of Anti-Social Personality Disorder now. In the past, they had a separate diagnosis under the old DSM formats. The name Sadism comes from Marquis de Sade (1740-1814) a French philosopher and writer. His works combined philosophy with sexual fantasies and violent behavior. Sadists are individuals who crave cruelty. It is not clear whether this behavior is inherited, developed or learned. Not all sadism is sexual or involves killing, rather it is about inflicting pain on others that Sadists find exciting or pleasurable. Unlike Psychopaths, they are not as calculating about the abusive behavior, instead, it is all self-pleasuring.
