What the Size of Your Pupils Says About Your Intelligence

The size of your pupils can say a lot about your brain power?

A new study done at Georgia tech linked the size of your pupils to how intelligent you are and researchers say people with eyes that have larger ones might be smarter in general. More than 500 people aged 18 to 35 from the Atlanta area were used in three different studies. Participants were asked to complete cognitive tests that measured the capacity to reason through new problems, the ability to remember information over a period of time, the ability to focus attention amid distractions. Those with a larger baseline pupil size scored higher, leading them to believe that there’s a relationship between the brain and eye.
