What’s in it for me? Guard against high-conflict personalities

High-conflict individuals, such as sociopaths, manipulators, and narcissists, can appear in every area of life – work, family, and even romance. They might look like a charming coworker who constantly undermines you behind your back, a family member who uses guilt to control your behavior, or a romantic partner who twists your words to make you feel like you’re the problem.

High-conflict individuals are everywhere. And these individuals are experts at hiding their true nature, often deceiving everyone except their targets. If you’ve already experienced their destructive tactics, you know how deeply destabilizing they can be.

The good news is that most people – 80 to 90 percent – are trustworthy and will behave as expected. The bad news? That remaining sliver of the population is made up of five types of individuals who can wreak havoc in your life, from your career and finances to your health and sanity.

Learn more about them in this Blink.

Understanding high-conflict personality types

Before diving into the five specific types of high-conflict individuals who can wreak havoc in your life, let’s first understand the overarching category they belong to: high-conflict personality types. These individuals are distinguished by predictable patterns of thinking, feeling, and behaving that consistently escalate rather than defuse conflict.

Four key behavior patterns are characteristic of high-conflict individuals. First, they engage in all-or-nothing thinking, viewing conflicts in black-and-white terms. For them, the only acceptable outcome is complete agreement with their demands, and they often react to dissent by abruptly severing relationships.

Second, they display intense and unmanaged emotions, surprising others with disproportionate outbursts and fixating obsessively on past grievances.

Third, their extreme behaviors and threats can range from spreading rumors and lying to physical aggression or complete withdrawal. These actions may stem from their volatile emotions or a desire for dominance, and they often show little awareness of the harm they inflict on others.

Finally, the most telling trait is their preoccupation with blaming others. They intensely and repeatedly fault those around them – especially close relationships or authority figures – and direct their anger and criticism at a specific “target of blame.”

Recognizing these behaviors is the first step to navigating interactions with high-conflict personalities while safeguarding your own well-being.

The “I’m superior, you’re nothing” type

What do Lance Armstrong and Saddam Hussein have in common? Both exhibit traits of high-conflict narcissistic personality types. Consider Armstrong: He engaged in systematic doping to preserve his image as a “winner,” dismissing truth-tellers with disdain and showing no remorse. Hussein, like many authoritarian figures, ruthlessly discarded allies and disregarded human suffering when relationships lost their utility. Both examples highlight how narcissistic high-conflict personalities can do serious damage to those around them.

So, what is a narcissist? These are people who see themselves as superior and act accordingly. Initially charming, they soon reveal an entitled, demeaning attitude.

The “love you, hate you” type

Have you ever seen The Devil Wears Prada? Meryl Streep’s character, Miranda Priestley, exemplifies the high-conflict borderline personality type. Miranda oscillates between being a charming mentor and a tyrannical, unpredictable boss. She offers Andy, her assistant, unique opportunities, but constantly threatens to fire her. Meanwhile, Andy behaves as many targets of blame do: trying to please Miranda while getting caught in her schemes. The movie ends happily when Andy breaks free, but not all borderline relationships conclude so neatly.

High-conflict borderline personalities can seem charming and wonderful for long periods – until you trigger their abandonment fear. Then, they may explode with rage, spread rumors, take legal action, or even lash out physically. They often turn others against their target, using intimidation to ensure compliance. Their words often betray a pattern of all-or-nothing thinking, particularly around their perceived victimhood. Statements like, “Everyone has taken advantage of me!” or “No one has ever been there for me!” are common.

The “cruel con artist” type

Ted Bundy, the notorious serial killer of the 1970s and ’80s, exemplified the high-conflict antisocial personality type. His chilling modus operandi often began with a calculated act of vulnerability: wearing a cast and asking for help loading books into his car. When his female victims leaned into his car, he shoved them inside. This ruse preyed on empathy, allowing Bundy to trap his victims. While not all high-conflict antisocial personalities commit crimes as heinous as Bundy’s, they share a pattern of deceit, risk-taking, and a disturbing lack of remorse.

Antisocial high-conflict personalities thrive on dominating others, and routinely violate societal norms. Some of this behavior may be biological – research shows they experience a lower heart rate during conflict, making them adept escalators and fearless risk-takers. While most will not commit murder, they may engage in unethical or reckless behaviors such as chronic lying, tax fraud, speeding, or running multiple scams – like juggling several families simultaneously.

The “highly suspicious” type

The neighbor who accuses you of stealing their parcels. The coworker who warns you that no one can be trusted. The partner who is convinced you’re having an affair. These individuals might all share traits of a high-conflict paranoid personality type.

High-conflict paranoid personalities are driven by a deep-seated belief that others are out to harm them. They hold grudges for perceived or entirely imaginary slights and see conspiracies everywhere. Early encounters with them might seem innocuous as they attempt to recruit you as a negative advocate – enlisting your support against a perceived enemy or conflict. Only later might it become clear that these conflicts largely exist in their mind.

The “dramatic, accusatory” type

On the day of her father’s funeral, Amy hoped to grieve alongside her mother, Nadine. Instead, Nadine’s behavior turned the day into a spectacle. She accused Amy of “murdering” her father, claiming his health deteriorated after Amy moved away. Later, Nadine collapsed into sobbing hysterics, demanding a promise that Amy would never “abandon” her like she “abandoned” her father.

This is the hallmark of a high-conflict histrionic personality. These individuals crave being the center of attention, often to the detriment of others. Their emotions are exaggerated, their relationships are often misjudged as more intimate than they really are, and they consistently manufacture drama. Like actors commanding a stage, they have a knack for capturing attention – but their performances are fueled by dysfunction, not artistry.
