Psychologists have suspected that personality influences how we visually take in the world. Curious people tend to look around more and open-minded people gaze longer at abstract images, for example.

The eyes really are a window to the soul. The way they move can reveal your personality type – a finding that could help robots better understand and interact with humans. Psychologists have long believed that personality influences the way we visually take in the world.
