Men with brown eyes have more trustworthy faces than men with blue eyes, according to a new study that proposes sexual selection of women in Europe about 10,000 years ago could be the cause.
Various facial traits, such as larger noses and higher set features, have previously been associated with perceived traits such as trustworthiness, dominance and attractiveness, which in turn can indicate political success or salary of the person. But this was the first study that looked at eye colour and perceptions of trustworthiness.
