The term “narcissist” is so loosely thrown around these days that it’s hard to determine who in your life actually is one.
Thankfully, human behavior expert Liz Rose shared with The Post a handful of nonverbal cues that may indicate you are in the presence of this personality type.
“People tell you who they are in the first five minutes. Most of us just ignore the signals,” she pointed out.
She explained that narcissists have very specific body language tells, and once you know what to look for, you can spot them fast.
“Clinically, Narcissistic Personality Disorder is a pattern of grandiosity, lack of empathy, and a deep need for admiration. What most people call a ‘narcissist’ is someone whose sense of self depends on being seen as superior, special, or entitled,” Rose explained.
According to Rose, the term narcissist has been co-opted to describe anyone who acts like a d–k.
“Culturally, people are becoming more aware of manipulative or emotionally unhealthy behavior, which is a positive step. But the downside is that we sometimes skip nuance and label people too quickly,” she told The Post.
She underscores that not every arrogant person, mother-in-law, or insufferable ex is a narcissist.
“Sometimes people are immature, insecure, stressed, or simply having a bad day. Real narcissism shows up as a pattern, not a single moment.”
Part of what separates a bad day from true narcissism is consistency.
“If someone repeatedly dismisses other people’s feelings, dominates conversations, reacts poorly to feedback, and needs constant validation, you’re likely seeing something deeper than a bad day.”
Rose imparts that a tremendous amount of conscious and subconscious information is transmitted through body language, and physical cues can point to narcissism or narcissistic tendencies.
“For narcissistic personalities, certain cues leak out automatically because they reflect internal attitudes of superiority. The person may not consciously think, ‘I’m going to demean this person,’ but their nervous system and facial expressions reveal how they’re actually evaluating the interaction.”
Here are the cues to be on the lookout for.
Eye scanning
Eye scanning, the number one nonverbal cue of narcissism, is in direct service of that unholy trinity.
“They’re always looking around the room searching for better attention, even while you’re speaking. That is called status scanning.”
Smirking
Rose shared that smirking can be a key indicator of narcissism as it’s used to signal superiority and suggests evaluation rather than warmth.
“One corner of the mouth lifts slightly, almost like a half smile, while the other side stays neutral. It’s subtle and often very quick. Unlike genuine smiles, the eyes usually don’t soften or crinkle,” she said.
Rose said the smirk is tied to contempt, adding that if a person smirks during conflict or when someone else is being vulnerable, that’s a big-time red flag.
“Even when someone is trying to appear sympathetic or caring, a brief flash of that expression can leak out if they internally feel above the other person. It’s like a crack in the mask, very quick, but very telling,” she added.
Exaggerated expressions
Rose argues that narcissists often deploy dramatic facial movements that feel performative or slightly off, a tactic that allows them to manipulate emotional attention.
“Narcissistic individuals often amplify signals of status, upright posture, controlled movements, strong eye contact, and exaggerated confidence,” she explained.
Invasive touch
Rose imparts that narcissists will often display dominance through invasive touch or by violating the personal space of another person.
“Personal space is deeply connected to power and boundaries,” she said.
“Standing slightly too close, touching someone early, or leaning in quickly can create psychological pressure. It forces the other person to either accept the intrusion or push back.”
She notes that because many people instinctively avoid confrontation, they tolerate the invasion, which can unintentionally signal compliance.
“From a behavioral perspective, it’s a subtle dominance move, testing how easily someone’s boundaries can be crossed,” she said.
“People with healthy social awareness usually calibrate distance based on comfort cues. Someone who repeatedly ignores those signals may be revealing something important about how they relate to others.”
Stillness in place of empathy
“If you’re being emotional and they just stare at you, no head tilt, no softening, no warmth, that’s emotional detachment happening in real time,” the expert explained.
She notes that narcissistic personalities tend to light up when they’re the center of the conversation, but when the focus shifts from them, they are prone to disengage.
“Healthy people show curiosity. They ask questions and listen, whereas narcissistic personalities often steer the conversation back to themselves. That moment can tell you a lot about someone’s emotional orientation.”
Rose added that when it comes to narcissistic behavior, it is crucial to remember that people reveal themselves through patterns, not performances.
“Anyone can be charming for an evening, but character shows up in the small moments, how someone treats the waiter, how they respond when the spotlight shifts away from them, and how they react to boundaries.”
Above all, she encourages people to trust their instincts.
“Your body is constantly reading signals long before your mind catches up. If something feels off, there’s usually a reason.”
