Almost all studies of the sort show that more than 95% of right-handed people house their language center in the left hemisphere of the brain (the more logical side of the brain), where less than 5% have right hemisphere language centers (the more creative side).
Oddly, in left-handed people, over 70% still have left hemisphere language centers. Leaving about 30% of left-handed people with their "language part of the brain" on the more creative side - but not the majority of left-handed people still.
It would be interesting (if it were possible) to see how much this affects how this affects the content (or even style) of those who have language centers on the logical side of the brain to those who have it on the creative side.
Of course, the brain is a network. But the reason we are right or left handed in the first place is mostly determined by whether we use the right or left brain more abundantly. Many of the greatest artists in history (Da Vinci, etc.) were left-handed. How would this hold up with poets? With lawyers? With linguists?
Unfortunately, they usually cannot check which hemisphere the language center resides in until a person is dead or some other severe case. But it's interesting (to me) nonetheless. Why are so many right-handed people left hemisphere language people, and why are the majority of left-handed people also left-hemisphere language people - thought not quite as much?
