Brown eyed people appear more trustworthy than blue
People with brown-eyes are viewed as being more trustworthy than those having blue eyes, a research has revealed.
According to the research conducted by Karel Kleisner and colleagues from Charles University in the Czech Republic, the given assumption was violated only when the blue eyes belonged to a broad-faced man.
For the research, the authors asked study participants to rate male and female faces for trustworthiness based on two features: eye color and face shape.
A significant number of participants found brown-eyed faces more trustworthy than blue-eyed, whether the faces were male or female.
More rounded male faces, with bigger mouths and larger chins, were perceived as more trustworthy than narrow ones, but the shape of a female face did not have much effect on how trustworthy it appeared to the respondents.
To test which of the two features were more important, the researchers tried a third test, presenting participants with photographs of male faces that were identical except for one difference: eye color. Here, they found that both eye colors were considered equally trustworthy.
According to the study, it was not brown eye color per se that caused the stronger perception of trustworthiness but rather the facial features that were associated with brown eyes.
The research has been published in the open access journal PLOS ONE.
