A study on how the color of the eyes influence perception of trustworthiness showed that people tend to trust brown eyed people over the blue eyed.
The human brain interprets another person's face and expression to identify origin, emotional tendencies, health qualities, and some social information. This is called face perception. How the brain interprets the face would dictate how to socially interact with the person.
Face perception is domain specific, heritable and independent of the person's cognitive abilities. But it is influenced by environment, ethnicity, and to some extent, culture.
This process is highly adaptive in any social environment, especially for distinguishing a friend from a foe. Face perception provides information on the person's level of trustworthiness which helps the person succeed socially, economically, and in terms of extending his race, reproductively.
The amygdala (the part of the brain that is responsible for the "fight or flight" response) reacts to the information and sends the appropriate signal whether the person can be trusted or not. People with bilateral amygdala damage have problems judging a person's face and ultimately the person's trustworthiness.
The brain picks up many features of the face to process face perception. One part of the face that seems to have influence over how the face is interpreted are the eyes.
