(Yea, you guessed right), they're all south paws or left-handers. 1 out of every 10 persons of the world's population is left-handed. That gives rise to a number of myths and one which has particularly raised dust for over a century is the myth that lefties are smarter. Most of us at some point would have come across the myth of lefties being smarter, more intelligent or having higher IQ's than their right handed counterparts.
... the logic behind the myth
It is believed that the right side of the brain controls the left hand and vice versa. Scientists explain that hand function is a manifestation of brain function and is therefore related to cognition. Apparently, left handers have a bigger right side of the brain which helps them with such functions as spatial awareness and mental representation of objects. As if that wasn't enough, they also have bigger corpus callosums (the bundle of nerve cells that connect the two brain hemispheres). This meansads that they have an increased connectivity between both sides of the…show more content… For instance, one eye is able to perceive both sides of a view if necessary; most but not all of one side of the body may be paralyzed after a one sided brain injury; etc. In fact, if a whole brain hemisphere is removed at a young age, this redundancy and the brain's inate plasticity can mean that the higher mental functions can develop almost completely unimpaired. Thus it appears that while there may be some general rules about the hemispheric function specialization, the actual situation is much more complex than we ever thought. Hence, rather than form rules, they should be seen more as indicators and the plasticity and complexity of the brain appears to allow significant variations from these
