A study published in the journal PLoS One in 2014 found men (though not women) with a long face and wide-set eyes are perceived as more intelligent.

160 participants (75 men and 85 women) were asked to rate the photographs of 80 Czech university students (40 men and 40 women). The findings revealed that both men and women were able to accurately evaluate the intelligence of men from the photographs. Those with a narrower face, a thinner chin, and a larger, prolonged nose fitted the predicted stereotype of a higher IQ.

Trustworthy eyes

In 2007, researchers at ?rebro University in Sweden were able to link the iris patterns in our eye to certain personality traits. They found that a low frequency of crypts (wavy lines radiating out from the pupil) was associated with trustworthy and tender personalities.

Big noses are ambitious

A study of 1,700 photos of faces, or more specifically their noses, was published in the Journal of Craniofacial Surgery in 2013. The report was able to find 14 different nose types and associate them with different personality types.

Apparently, a person with a large nose tip is a financial planner, whereas if the tip is small or pointed, they don’t have much interest in money.

Large nostrils are meant to indicate a generous spender – but if all of the nose is large that indicates that the person in question has an ambitious personality.

Sexual orientation

40 gay and 40 straight people were studied by researchers at Charles University in Prague in 2013, to discern whether sexual orientation was linked to the shape of a man’s face. According to the study: “Gay men showed relatively wider and shorter faces, smaller and shorter noses, and rather massive and more rounded jaws, resulting in a mosaic of both feminine and masculine features."

Curved eyebrows show kindness

According to face reader Jean Haner, we can tell a lot from someone’s eyebrows. Those with curved eyebrows are kind and considerate, straight eyebrows belong on logical people and if you have diagonal eyebrows you are more inclined to react to a situation.
