How People Subconsciously Judge You Based On Different Facial Features

Blame your brain.

No matter how open and kind you are, your brain is doing its damnedest to trip you up based on the “look” of the other person you’re meeting with, talking to, or just viewing from a distance.

Getting to know someone seems like something that takes time, effort, and building a relationship with the other person.

But there are factors in our judgment that happen so quickly that we can’t stop them from taking place without us.


We can have “platonic love” and even a spark of romantic chemistry at first sight because our brains are constantly calculating things on our parts, taking information we receive into account subconsciously.

So while we talk to them and focus on whether or not they have spinach in their teeth (or in ours!), our brains are working like mad behind the scenes, giving us speculations about what the other person's looks might suggest about their personality.

And science says it's total garbage.

The basis of perception about a person starts much faster than we ever even realized.

In fact, it takes only about seven seconds for your brain to form an opinion of someone, and part of that is, unfortunately, based on something that scientists call "facial bias," which is how we perceive others.

Ever got a look at someone and determined that they were untrustworthy?

Then you can thank your brain for jumping to that conclusion based on something as minor as how attractive you think they are or if they're frowning. Yes, it turns out our brains are just massive prehistoric judgy jerks.


“We form these immediate impressions of people — we just can’t help it,” said Alexander Todorov, a psychology professor at Princeton University.

He is responsible for creating the study of facial bias and testing people's responses to computer-generated face models to determine what features they associate with positive and negative personality traits.

And it's also thanks to this lab test that we know our reactions to these initial first impressions are often highly inaccurate, and really don’t have a basis in science or reality of any kind. So yes, we are literally making judgments over people based on their looks and it’s all just Mean Girls nonsense.

The type of face you have subconsciously influences other peoples’ impression of you so that they end up forming an opinion before they’ve even gotten to know you. 

This also explains why people we find (personally or societally) to be attractive are often given better treatment and perceived to be nicer than less pretty people, just based on their level of attractiveness

For this same (nonsensical) reason, attractive people are also far more likely to rate higher in other positive traits, Todorov’s findings revealed, like being more competent, smart, or trustworthy.


Even the structure of your face can speak volumes.

Do you have a baby face?

Well, then people might just assume you’re weak, naïve, or submissive by nature, and since ladies tend to have this facial feature far more than men, it explains a lot, actually.

And your eyebrows pointing one way or the other could even throw you off your game.

Do you have an angry-looking face?

Then you’re going to be perceived as less likable and trustworthy — but at least you also get to be considered more powerful, too. And if you look happy, then people think you’re trustworthy — but they'll also think you're weak.

Todorov’s lab created these perceived traits on computer-generated faces and found that anything from the width of your face to the ghost of a smile on your lips can amp your attractiveness level to other people.

Changing even the smallest portion would change the way they may perceive you.

So what does this tell us about people?


Mainly that even if we’re normally even-tempered and slow to judgment, we can’t stop our brains from jumping to (sometimes ridiculous) conclusions.

Just like you really can’t judge a book by its cover, you also can’t judge a person by their looks.

So next time you find yourself doing it — because let’s face it, our brains are primeval throwbacks — then take a step back and try to reevaluate the situation.

You never know; maybe you can find a new friend from the situation that your brain had already written off with a pouty "Uh! No!" to begin with.
