New Study Shows Your Pupil Size Can Determine How Smart You Are

People used to say that dilated pupils can tell when you’re in love, but a recent study by the Georgia Institute of Technology (Georgia Tech) has found that your pupil sizes can actually tell more than that. Believe it or not, the size of your pupils could be an indication of your intelligence level.

The study, which was published on Science Direct, found that those with larger pupil sizes are more likely to have higher intelligence. To test this theory, the researchers conducted a study on 500 individuals in Atlanta from the ages of 18 to 35, and tested them based on three categories – reasoning, attention and memory.

In order to measure the participants’ baseline pupil size, the researchers used a high-powered camera and computer to capture the reflection of light off the pupil and cornea. As our pupils are highly sensitive to light, the tests had to be conducted in a dim lab to ensure accurate results.

The results found that people with a larger baseline pupil size could focus better during the “attention control” tests and generally perform better in the reasoning and memory tests too. In fact, the difference in baseline pupil size among participants who scored the highest and lowest throughout all three tests were so apparent that they were discernible to the human eye.

There is a logic behind this theory though, as pupil sizes are linked to the locus coeruleus, a part of our brain that’s responsible for producing noradrenaline, a hormone that regulates our perception, attention, memory and learning.

What do you think? Have you been told that you have large pupils? It might be time to celebrate now…
