A visual test recently showed that the brains of people with high IQ scores process sensory information differently.

According to the authors of a paper published in Current Biology, the brains of these people are automatically more selective when they perceive objects in motion, and are more likely to suppress larger background motion.

“It is not that people with high IQ are simply better at visual perception,” explains Duje Tadin of the University of Rochester. “Instead, their visual perception is more discriminating. They excel at seeing small, moving objects but struggle in perceiving large, background-like motions.”

The authors believe that it is not a conscious strategy but instead something automatic and fundamentally different about the way their brains work. This skill could be practical in a world filled with more information than we can absorb. This would explain why some brains are more efficient than others.
