The left and the right brain actually do different things in people. Just look at the epyleptic studies where they surgically separated the two halves of the brain. When blocking off the right part of the eye, those people were not able to name every day objects like a pencil. But they could pick it up and use it. When blocking off the left side of the eye they were able to call it a pencil, but not use it.
Yes, to an extent they do different things, but that's not what the person you were replying to was talking about. For several years there was this idea that "left-handed people are right-brain dominant, and right-handed people are left-brain dominant." And along with that went this whole astrology-tinged thing about the right brain being the creative half and the left brain being the analytic half and whatnot. It's pretty much nonsense.
