Narcissists have thicker, denser, more distinct eyebrows

Narcissists can be tricky to spot, especially if you are in a romantic relationship with one. This tends to be because they rely on using and manipulating others to fulfill their needs and desires, all while blending in like a chameleon.

There are three distinct types of narcissists, and they often behave in specific callous ways. But it can take some time to work out their patterns. Even when they are exposed for what they are, narcissists can still hook in their victims again by promising they will change, and giving out intermittent reinforcement.

But according to a new study, published in the Journal of Personality, you may be able to detect a narcissist by focusing on one particular facial feature, their eyebrows.

Researchers recruited participants to look at the faces of people who were all across the narcissistic spectrum, from a normal level to full blown narcissist,  and it turned out they were pretty good at identifying them.

Strangely, when participants were shown pictures of just the eyebrows, they could correctly identify the narcissists too.

They highlighted femininity, grooming, and distinctiveness when they picked out the narcissists, but results showed it was distinctiveness that was key,  narcissists tended to have darker, thicker, more distinctive eyebrows.

The researchers tested the results again by Photoshopping narcissists' brows onto the faces of non-narcissists, and vice versa, and the eyebrows gave the game away away again.

Eyebrows make our faces more recognisable, and in recent years they have become something of a fashion statement. Narcissists may like to make a statement with their brows so to tantalise potential love interests and make an impression.

As the authors wrote, they might "seek to maintain distinct eyebrows to facilitate others' ability to notice, recognise, and remember them; thereby increasing their likability and reinforcing their overly positive self-views."

It could also simply be because eyebrows give away more social messages than we realise. They are important for our facial expressions, but could also reveal subtle, subconscious information too.

"The ability to identify dark personality traits at zero-acquaintance provides particular value for avoiding exploitation and manipulation," the researchers wrote.

"The increasing incidence of narcissism underscores this value. Fortunately, people can accurately judge others' narcissism based on how they act, what they say, what they wear, and what their faces look like."

Whatever secrets eyebrows hold that mean they may reveal someone's dark personality, they could be reason enough to steer clear.
