Are you a righty? Or a lefty? These questions may bring you back to your middle school days, when you would ask your neighbor why they would write a certain way. But did you know that your fellow lefty is of a rare species? Only 13% of the United States population use their left hands on the regular! Some researchers think that the hand you use actually says something about the way you think. Righties use their right side while leftys use their left side. Sound about right? Perhaps! 25% of lefties use both sides of their brain equally. This data is inconclusive, however, since there is no total consensus of the population on their brain usage.
So, is there any real difference between the lefty population and the rest of the world? Sorry to disappoint, but probably not. Although 20% of the top scoring SAT group is left-handed, this is a small percent compared to the other 80%. However, there is also an overwhelming rightie population. Left-handed children may have received this trait from their parents, since 25% of children will be leftys if their parents are.
So, what are you? Are you a righty? Or a lefty?
