What do Einstein, Leonardo da Vinci, Julius Caesar, and Napoleon have in common?They were all left-handed! Beginning early in history, southpaws were feared, neglected, and punished because use of the left hand as considered evil. In fact, the Latin word for ''left'' is ''sinister''. Due to this prejudice against the left, left-handed people were forced to switch hands. This change caused many problems for lefties in school, which resulted in frustration, bad behavior, and high drop-out rates. Maybe that is why lefties were stereotyped as unintelligent, an idea that could not be further from the truth.
Researchers studying the brain have found differences in the left side and right side of the brain. Researchers believe that people who use more of left side of their brain tend to be more intelligent. They also tend to use language better and solve problems faster. However, one study also showed the left-brain people tend to have worse memories.
