2. Lefties have a higher IQ
Its is proven that a person can only use one side of their brains during their normal occasions. However, it has been noted that those people who tend to use both sides of the brain are lefties. This by itself makes them think faster and in a more diligent manner as opposed to the larger population of the rights handed people. This indeed increases their IQ hence they make up large sections of geniuses.
The evidence is not yet clear but researchers believe that they make up the greater percentage of the population with the highest intelligence. Examples of the geniuses who were left handed include Benjamin Franklin and Isaac Newton. The explanation behind the high IQ is because circumstances have forced them to use both sides of their brain more often therefore allowing them to process large amounts of information at once and with ease.
