HANDS & IQ – How to recognize a smart hand: 3 – Dr Oz says: ‘in a way, left-handed people are smarter’!
January 24, 2011
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).

On Labor Day 2010, the daily Rasmussen Report about Barack Obama’s popularity displays that 26% of the nation’s voters ‘Strongly Approve’ of the way that Barack Obama is performing his role as president. Forty-six percent (46%) Strongly Disapprove, giving Obama a Presidential Approval Index rating of -20.
After winning the Nobel Peace Price in 2009, and while his popularity around the world – more and more people in the US continue to change their mind, and the power appears to slip from his hands. Want went wrong? Where did the magic of the 7th left handed US president go?
INTO THE HANDS OF BARACK OBAMA – A FULL HAND PORTRAIT:
lefty facts… Left-Handers Day was first celebrated on August 13th, 1976 by Lefthanders International). The purpose of the day is to both celebrate left-handedness and raise awareness of the unnecessary biases against left-handers. The holiday is still proudly observed by lefties every year on August 13th. Enthusiastic supporters may organize lefty vs. righty sports matches and encourage right-handers to try using left-handed products to experience the same awkwardness they are too often forced to endure.

What causes left handedness?
The factors that contribute to handedness, are not completely understood. Both genes & environmental factors are involved, but the brains play a significant role as well. The left brain, which controls the right hand, is dominant in most people and is the center of logical thinking. But in left handers is the right brain more dominant. And because the right brain is more associated with art, creativity, phantasy & emotional expression – the might explain why research has indicates that left handedness is about twice as often seen in artists than in the general population.
Where does left handedness excel?
Typical fields where left handers relatively often excell are:
7 Out of the last 14 US presidents were left handed, and Barack Obama’s final ‘rival’ – senator John Mc Cain – is left handed; in 1992 all three presidential candidates (George H.W. Bush, Bill Clinton & Ross Perot) were left handed!
Left-handers excel particularly in tennis, baseball, swimming and fencing.
Leonardo da Vinci, Michelangelo & Isaac Newton were left handed, and 1 in 4 Apollo astronauts were left handed.
A few other exceptional historical ’lefties’ from various fields are:
Julius Caesar, Fidel Castro, Charlie Chaplin, Robert DeNiro, M.C. Escher, Mahatma Gandhi, Bill Gates, Alexander the Great, John McEnroe, Niccolò Paganini, Rembrandt van Rijn, Romario de Souza Faria, Mark Twain.
