Your question is interesting. The brain of a human being is specialized for language in the left brain, unlike the lower animals. Therefore, the left brain deals with logic, order, organization, and language. The right brain deals with visual pictures, sounds that are not language sounds, and images. Your nervous system below the neck is reversed, so your left hand inputs to the right brain, and the right hand inputs to the left brain. This is why many people think that "left handed people are more creative," because the left hand sends input to the right brain which is where the "creativity" area is. However, you have a connector between the two hemispheres of the brain, called the "corpus callosum." If the right brain gets an input of language or logic, it will send the information across the corpus callosum to the left brain for processing. And, if a right-handed person draws a picture or does something creative, the information will go to the left brain first, but then it will go through the corpus callosum "connector" to the right brain. So, no, left handed people are not necessarily any more creative than a right handed person. The information from either hand will go to the proper processing center in the brain through the corpus callosum. There are many creative right-handed people in this world, too.
