It's a fact....apparently~ Left-handed people are smarter!:D
The brain is split into two hemispheres...and while each half of the brain does broadly the same thing as the other, there are some differences...Basically, in humans, and lots of other mammals, one side of the brain is slightly dominant – this is why you favor one hand over another. Some studies have shown that left-handedness is linked to intelligence; left-handed people tend to score higher on IQ tests, and can also often finish these tests faster than right-handed people. Other studies, however, have shown that left-handed people have a wider range of IQs – making them over-represented in both the highly intelligent and the rather dim-witted sections of the population.
