Study shows brown eyes appear more trustworthy than blue

ST. LOUIS, MO (KTVI)- When it comes to deciding who to trust, a study reveals the eyes have it.

Researchers in the Czech Republic asked study participants to rate male and female faces based on eye color and face shape. A majority found brown eyed faces more trustworthy than blue-eyed faces, whether male or female.

Males with rounded faces, bigger mouths and larger chins were perceived as more trustworthy than narrow faces. The shape of a female face had little effect on trustworthiness.

Researchers say it isn't the brown eye color that caused the stronger perception but the facial features associated with the color.
