4 Eye colour linked to the facial structures and the trustworthiness
In a study conducted by Karel Kleisner of Charles University in Czech Republic, it was found that eye color had some correlation to the face structures and trustworthiness. According to the research, men with brown eyes had broader chins, closer and prominent eyebrows, larger mouths and noses. In contrast, men with blue eyes had finer features, such as down turned mouths, smaller eyes, longer chins and widely spaced eyebrows, and in general these faces are more angular in appearance. It was also found that public perceptions about trustworthiness from the audience tested showed that men with blue eyes were less likely to garner trust and in fact the ability to be trusted had a better correlation with the shape of the face as blue -eyed men with broader faces were likely to be trusted as compared to their thin faced counterparts.
Female eye colour and face structure had absolutely no correlation to being trusted by others or not.
