Here's how people judge you based on your face
We assume more attractive people rate higher in other positive traits, too, perceiving them as more competent, intelligent, trustworthy, and more.
We associate baby-faced appearance with physical weakness, naïvety, submissiveness, honestness, kindness, and warmth. Baby-faced appearance includes relatively larger eyes, a rounder face, a larger ratio of cranium to chin.

Neutral faces often resemble emotional expressions. Angry faces are perceived as less likable and trustworthy and more powerful, hostile, and threatening, while the opposite is true for happy faces.

Todorov’s lab modeled perceived traits by having US college students evaluate computer-generated faces. To avoid getting into questions of race, the study used only white faces.
Perceived competence increases from left to right in the faces below. Associated traits include darker skin — in this case a factor of gender, not race — and attractiveness.

Perceived dominance increases from left to right. Associated traits include include darker skin and masculine features.

Another type of facial bias: more typical faces are viewed as more trustworthy. This bias contributes to racism and xenophobia.

People also react more positively to faces that resemble their own. This was tested by having people evaluate the trustworthiness of morphed faces containing varying percentages of their own face.

Troublingly, people also judge criminality and remorsefulness based on faces, as both Todorov and Walker have shown. Perceived criminality increases from left to right in the top two rows; perceived remorsefulness in the bottom two.

Studies have shown that facial bias affects who we vote for, date, hire, prosecute, convict, and more.

What’s wrong with facial bias?
Although the face can give some clues to behavior, Todorov argues that people tend to imagine false insights or overemphasize real ones, when they would be better off consulting other information. Also links between facial morphology and behavior may only be the result of societal bias, where people act a certain way because we expect them do, and facial bias just reenforces these stereotypes.
