People with brown eyes were judged to be more trustworthy by a panel of volunteers than their blue-eyed peers in a study by researchers from Charles University in Prague.
But when a separate group of volunteers were shown photographs of men with identical faces but whose eye colours had been artificially changed they were rated as looking equally trustworthy.
The findings suggest that the key to being trusted lies in facial characteristics which are shared by people with brown eyes but which are not related to eye colour, experts said.
Brown-eyed men, for example, tend to have rounder faces with broader chins, wider mouths with upward-pointing corners, larger eyes and eyebrows closer to each other – qualities which are more masculine and therefore more trustworthy.
In contrast, men with blue eyes shared qualities which made them appear more shifty such as smaller eyes and narrower mouths with downward-pointing corners.
People with green eyes, of course, should never, ever be trusted with anything. Bunch of shady assholes, the whole lot of them.
