What causes left handedness?
Most of the current research suggests that left–handedness has an epigenetic marker—a combination of genetics, biology and the environment.

How do you determine if your child is left or right handed?
If you think your child doesn’t have a dominant hand, place a variety of objects directly in front of her throughout the day and make note of which hand she uses to reach for them.

Do left handers have higher IQ?
The bulk of the studies included in the systematic review reported no differences in IQ scores between left– and right-handers. No differences in mean IQ scores were found between right-handers and non-right-handers as well as between right-handers and mixed-handers. No relationship differences were found.
Do left handers think differently?
While some reasons for the differences in thinking and functioning may be genetic and anatomical, left–handedness is behavioral as well. Things left–handers do differently are often influenced by the societal implications of having a dominant hand that differs from the general public.

What are lefties good at?
Left-handed people are said to be good at complex reasoning, resulting in a high number of lefty Noble Prize winners, writers, artists, musicians, architects and mathematicians. According to research published in the American Journal of Psychology, lefties appear to be better at divergent thinking.

Why are lefties so rare?
So why are lefties so rare? Scientists have long tried to answer this. In 2012, researchers at Northwestern University developed a mathematical model to show that the percentage of left-handed people was a result of human evolution — specifically, a balance of cooperation and competition.
Is Mark Zuckerberg left handed?

Are lefties brighter?
The takeaway. While there are curious differences between lefties and righties, a higher intelligence level probably isn’t one of them.
