Lefties make up only about 10 percent of the population, but studies find that individuals who are left-handed score higher when it comes to creativity, imagination, daydreaming and intuition. They’re also better at rhythm and visualization.
A new study suggests lefties are rare because of the balance between cooperation and competition in human evolution. The findings come thanks to some data from the sports world. Representing only 10 percent of the general human population, left–handers have been viewed with suspicion and persecuted across history.
Similarly, do left handers think differently? The brains of left–handers and right-handers are somewhat different. Left–handers tend to have less lateralized brains, meaning that the two halves of the brain are less distinct than in right-handers. The study of left–handers can help us answer several important scientific questions.
In this manner, do left handers have higher IQ?
Right-handers rejoice, handedness may affect intelligence. The idea that left–handed people are more intelligent than right-handers is a myth. There have been lefty geniuses in history like Leonardo da Vinci, but this is not part of a larger pattern. If anything, the opposite is true.

Is becoming ambidextrous harmful?
Although teaching people to become ambidextrous has been popular for centuries, this practice does not appear to improve brain function, and it may even harm our neural development. Recent evidence even associated being ambidextrous from birth with developmental problems, including reading disability and stuttering.

Was Einstein left or right brained?
You may even see people tying Einstein’s genius to his left-handedness. While he was certainly right-handed, autopsies suggest his brain didn’t reflect the typical left-side dominance in language and speech areas. His brain’s hemispheres were more symmetrical—a trait typical of left-handers and the ambidextrous.
Do left handers have an advantage in sports?
