Beauty and brains are the oft-citied qualities of a true catch. And whether or not it’s true, when a person exhibits the former, we tend to think they have the latter, too.

As a result of beauty bias, we prescribe attractive people with positive traits they may or may not possess. New research published in the journal PLOS One reveals that along with being kind, trusting and more worthy of forgiveness, good-looking people are perceived as smarter, too.

Studying this phenomena is a little tricky: The perception of attractiveness and intelligence are both subjective and left up to the individual observer. In attempt to regulate study participants’ definition of intelligence, researchers asked about other ratings that fall under the umbrella of “smart.” They asked about conscientiousness and academic performance, two values that can be attributed to intelligence.

The study focused on photos of 100 students at the University of St. Andrews, limited to Caucasians in order to eliminate any potential racial bias from the study. To ensure as level playing field a possible, the students were told to make a neutral expression while being photographed, and not to wear any makeup or jewelry.
