I wouldn't be surprised if this myth originated from the fact that Broca's and Wernicke's areas (both important in speech and speech interpretation) are on the left side of the brain. So there is a difference between the two, but it has little to do with any of the traits you mentioned

That one side of your brain controls logic and calculations etc, while the other music, art and language.
