The study tells us that participants looked at faces of women and men and were asked to “rate their trustworthiness” only by looking at their eyes and face shape. Many felt those with brown eyes to be more trustworthy than those with blue, but eye color might not be the defining factor.
For men, it mostly came down to face shape: participants said they would trust men with round faces and large mouths more than they would trust men with narrow faces. For women, the shape of their faces did not affect the results the way it had for males. Interestingly, when shown identical male faces with different colored eyes in a separate study, participants expressed they would trust the men equally.
The conclusion was that facial features associated with brown eyes are what makes someone appear more trustworthy.
So the questions remain: why are men judged more on the shape of their face, while women are judged more on their eye color? And what is it about face shape or eye color that makes someone trust or not trust you? Those answers are yet to come, but for now we are intrigued to take a look at some of our favorite blue and brown-eyed celebs, with a variety of face shapes, and see what you think.
