The Post 9 Nonverbal Signs of Narcissism That Researchers Say Often Pass for Charm First Appeared In Crafting Your Home
Seventy-three college freshmen took turns introducing themselves to classmates they had never met. Then everyone rated everyone. The students who scored higher on a narcissism questionnaire were the ones the group liked most.
That 2010 experiment on first impressions helps explain why the trait is so hard to catch early. The clues exist. They just happen to look good.
One note before the list. The researchers behind these studies measured narcissism as a personality trait that all of us have to some degree, not as a diagnosis. Each sign below is an average across a group, so no single one tells you much about the person sitting across from you.

1. Clothes that cost money and want you to know
In a 2008 study of full-body photos, strangers guessed who scored high on narcissism. They did about as well as people do when they judge other personality traits from a snapshot. The high scorers were more likely to wear expensive, flashy clothing.
2. A polished look that took real time
The same photos showed a second pattern: a neat, organized appearance that seemed to take a lot of preparation. Nothing wrinkled. Nothing thrown on at the last minute.
3. Bold, distinct eyebrows
This one sounds made up. It isn’t. In a 2018 study of faces and narcissism, Miranda Giacomin and Nicholas Rule tested which feature gives the trait away, and the answer was the eyebrows. Thick, dense brows drew higher narcissism ratings. When the team swapped eyebrows between photos, the ratings moved with the brows.
4. A self-assured face
Back to those freshmen. Observers scored each speaker’s facial expression on scales such as timid versus self-assured. Students higher in narcissism landed on the confident, charming end.
5. Straight posture and take-charge movement
Their bodies told the same story. High scorers stood straighter, and raters called their movements dominant instead of withdrawn. A separate group later watched the clips with the sound off and still preferred the high scorers.
6. A steady stream of selfies
A University of Georgia review of 62 studies pooled data on more than 13,000 people. Grandiose narcissism, the outgoing and confident kind, went along with posting selfies more often. The link was modest, and the authors stressed that it shows a connection, not a cause. Plenty of people post selfies because they had a nice day.
7. An oversized signature
Accounting researchers wanted a way to gauge executives who would never sit for a personality test. So they ran a lab test of signature size first: students filled out a questionnaire and signed their names. Bigger signatures went with higher narcissism scores.
Co-author Chad Ham warned against reading much into one autograph. To learn anything from signature size, he said, “you need to have a large sample. It’s an ‘on-average’ effect.”
8. A mood that doesn’t move with the room
Most of us catch feelings from the people around us. Psychologists call this emotional contagion. A 2015 paper by Anna Czarna and her co-authors found that people higher in narcissism were less prone to it, for good moods and bad ones.
That research tracked what people said they felt, not what their faces did, so the visible sign is indirect. Suppose a friend shares rough news at dinner and the whole table sags except one guest, who is still waiting to finish a story. One flat moment proves nothing. A habit of them is worth noticing.
9. A long look in the mirror (maybe)
The oldest cliché has the shakiest support. In a 1997 study, high scorers said they checked mirrors more often, and they chose to watch video of themselves over video of someone else. A 2021 eye-tracking study failed to find the expected link between narcissism and time spent gazing at one’s own reflection. A 2025 study did find one, during a simple task with a mirror in view. Call this sign unsettled.
Why this list should slow you down
Read those nine again and count how many would bother you on a first date or at a neighborhood cookout. Good clothes, good grooming, a confident face, strong posture. Most of them are things we reward.
The 2010 study made the same point with numbers. The two parts of narcissism that cause the most trouble over time, a sense of entitlement and a habit of using people, were the parts strangers found most attractive at first sight.
So the practical lesson has little to do with eyebrows. A dazzling first impression is still a first impression. Enjoy it, then give the person a few more meetings. Charm shows up in seconds. How someone treats you after they stop getting their way takes longer to see, and it tells you far more.
