Dr Oz: 'left-handed people are smarter'

Are left-handed people smarter than right-handed people?

“Well, in a way, left-handed people are smarter, and I’ll tell you why,” Dr. Oz says. “Left-handed people can deal with more incoming information that doesn’t come in an organized way.” Dr. Oz says this is because of the way the brain develops when a baby is in its mother’s womb. “The left brain normally controls your right side, which is really powerful,” he says. [In left-handed people], it allows the other side, the right brain, to become an equal partner.”

Because left-handed people can use both sides of their brain more readily, Dr. Oz says, they can process information coming into their brain in different ways more easily. “That’s why athletes do so well when they’re left-handed. And there are a lot of presidents who have been left-handed, and there are a lot of folks who, because they can deal with a lot of complicated issues at once, work pretty effectively,” he says.

But Dr. Oz says although you may write with one hand, parts of the body on the other side—such as an eye—can still be dominant. To determine which eye is dominant, Dr. Oz says to cut a pencil-sized hole in a piece of paper and hold it away from your face. Look through the hole at an object using only your right eye, then only your left. Dr. Oz says whichever eye you can still see the object through the hole with is your dominant eye.

Dr. Oz says many people are dominant with one eye and dominant with the opposite hand. “There are lots of different reasons you want to know [which eye is dominant]. If you were playing sports, it’s sort of helpful,” he says. “But folks actually use their different parts of their brain very differently, and it’s sort of cool to understand how it all comes up.”

A FEW MORE FACTS ABOUT LEFT-HANDEDNESS:

While left-handedness (ranging from moderate through strongly left-handed) is found in approximately 10% of the population

• Four out of five (80%) original Macintosh computer designers were left handed;

• Five out of the last seven (71%) US presidents were left handed (Barack Obama’s runner-up – senator John McCain – is also a lefty);

• One out of four (25%) Apollo astronauts – who were all selected e.g. by their high intelligence – was left handed;

Mensa International  (the largest and oldest high-IQ society in the world) claims that 20% of their members are left handed;

• A 1988 study reported: 16.9% of 266 United States Chess Federation players being left-handed or ambidextrous (included in the sample were e.g. 138 male Chess Masters, 18.1% was left-handed or ambidextrous).

  1. There is some obvious debate about the ‘Smartness’ of people who are right handed versus left handed individuals and vice versa. I am right handed. A definition for ‘Smartness’ is really required.

    I certainly do not claim to be smarter than all left handed people, yet I do claim to have earned more college semester hours (430 semester hours) at more Universities (nine different Universities) than any living or dead human being, thus the United States and World Record. In addition, if you take a look at my chemistry website (www.AbsoluteConfiguration.com or also listed at the website, http://www.RSconfiguration.com), you will note that spatial orientation and/or creativity, is not necessarily a higher trait of left handed individuals.

    It is noted though, left handed people are encountered with 90% right handed people. Imagine being left handed and you hold your hand out to shake the hand of another person, which hand would you hold out in order to shake hands with the other person, considering 90% of people are right handed? Or, as a left handed person, would you wait for the other person to hold out their hand, in order to shake hands, so that you shake hands with the correct hand? Obviously, left handed people are more challenged by society, because 90% of people are right handed.

    The previous paragraph is mentioned without taking into account, the left and right sides of the human brain and their respective functions, of which, is also a constant in the equation of the definition of ‘Smartness’.

    In the United States, people are trained to look left and then right. Take the example of driving a vehicle or crossing the street. You would look left first, before you look right, because of the oncoming traffic would be, first, from the left. When reading a book, at least in the United States, we read from left to right.

    There are 1,000’s of very important people, throughout history, that attained a very high status amongst other people in society. Those people are both right handed and left handed. So once again, the definition of ‘Smartness’ is required.

    Hope that helps, at least a little bit 🙂
