The surprise came when tests with larger objects showed just the opposite: individuals with high IQ were slower to see what was right there in front of them. ‘There is something about the brains of high-IQ individuals that prevents them from quickly seeing large, background-like motions,’ Tadin added.

What does your eye size say about your intelligence?

The pupils are the black part at the centre of the eye which dilate in response to changes in light.
