Is there any connection between human behavior and facial features?

Answer 1

Facial features may dictate human behavior through self-fulfilling prophecy and halo effect.

For example, if someone sees a woman with a beautiful face, then they'll act toward the woman positively, through the halo effect. As such, the woman will act positively back - and by doing so, her facial features have defined her behavior. In a reverse situation, someone interacting with a woman with an ugly face may act toward the woman less positively, neutrally, or negatively. By doing so, the woman will return the behavior in kind.

Another example would be a boy with a face reminiscent of Mike Tyson. As he grows up, his friends and parents all say he looks like Mike Tyson. As such, he gains an interest in boxing and acts more aggressively because of it.

One last example would be the racial divisions and cultural expectations of every race, as dictated by their facial features / skin color.

Answer 2

yes there is, when humans react to something its their faces that show their behave.
