The saying that left-handed people are smarter than right-handed ones is a myth. Many left-handed geniuses in history like Leonardo da Vinci have excelled, but no link has been found between handedness and smartness.

n 2015, a compilation of results done by Dutch researchers, from over 30 previous studies that involved over half a million people, found that there was no tie between handedness and verbal ability but instead showed a small advantage for right-handers in the spatial ability.

A recent study also found that left-handed people were more commonly seen with low IQ than people with standard IQ.
