Why People With Bigger Pupils Are Smarter

The eyes are the mirror of the soul, and the pupils could be the mirror of the intelligence, according to a recent scientific study. Research from the Georgia Institute of Technology finds a correlation between the basal size of the pupils and the degree of intelligence of a person. According to the researchers, the size of this part of the eye is directly related to a part of the brain called the locus ceruleus. The researchers, from the School of Psychology, are Professor Randall Engle, and graduate student Jason Tsukahara.
