Having Larger Pupils May Be a Sign of Intelligence, a Study Shows

Looking at someone's eyes can give you a glimpse into their emotional state. You may be able to rdiscern whether they are happy, sad, or angry. Little did we know that eyes may also be the window to intelligence, and could possibly tell you about someone’s IQ. A study from researchers in the School of Psychology found that people with large pupils may be more intelligent than those with smaller pupils. A lot depends on the right lighting conditions, as mentioned in the study conducted by graduate researcher Jason Tsukahara, and Professor Randall Engle, principal investigator in the Attention and Working Memory Lab.
