There’s no proof that some people are left-brained or right-brained. That’s the conclusion reached by University of Utah researchers after a two-year study of the human brain.
For a few decades now, people have seized on the concept of creative people being somehow right-brained and logical people being somehow left-brained. If that irritated you because it seemed like a slam on the creative person’s ability to think logically and clearly, join the club.
Finally, somebody has come forward to call bogus on the bull.
The University of Utah neurologists obtained brain scans taken during an MRI analysis of their resting brains. They studied over 1,000 scans of young people between the ages of seven and 29.
It turned out that people simply aren’t left-brained or right-brained in the way that they’re left-handed or right-handed.
Sure, there are air-headed creative people who can’t think. And there are rod-up-their-butts logical types who can’t break out of a mold. But their personality doesn’t have anything to do with whether or not the left or the right side of their brains was more active.
Jared Nielsen, who assisted in the study, said in a statement that, “[W]e just don’t see patterns where the whole left-brain network is more connected or the whole right-brain network is more connected in some people. It may be that personality types have nothing to do with one hemisphere being more active, stronger, or more connected.”
A complete look at the new left-brain, right-brain study and its findings have now been published in the open access journal PLOS One.
But don’t expect people to stop talking about left-brain or right-brain personalities just because the theory has been debunked. Ask the astronomers who are always battling back astrologers about how well that’s working out for them.
