Is it manly? Wait until you see the whites of her eyes, American scientists insist

Is it manly? Wait until you see the whites of his eyes, American scientists insist, as they unveil little-known indicators that can dictate a man’s masculinity.

How do we judge virility and femininity? One way is to look at the whites of people’s eyes, scientists have found.

Called ‘sclera’, white is more yellow and red in men, but bluer and greener in women, and we subconsciously notice the difference.

“People use sclera color as a cue to make judgments about sex-related faces. It’s not something people are consciously aware of,” said Professor Richard Russell of Gettysburg College, head of the study. Pennsylvania in the United States.

Traditional indicators such as soft skin and plump lips in women or a chiseled jaw and strong nose in men also play their part.

Then, in the first experiment of its kind, the team created pairs of photos of identical faces without strong male or female traits.

By changing the colors of the sclera, they found that people were much more likely to judge red-yellow tints as masculine and blue-green as feminine.

But the effect wore off with older people, says the research, published in the journal Archives of Sexual Behavior.

Professor Russell believes this is because less sclera is visible as our aging eyes say.

By changing the colors of the sclera, they found that people were much more likely to judge red-yellow tints as masculine and blue-green as feminine.
