Are You Right or Left Brain Dominant?

    Actually it turns out that we are neither.

    This is one of 7 myths about your brain that are debunked in the following short Science Alert video.

    It's funny that what was once lauded as fact and established and proven by the biggest names and authorities in science suddenly becomes myth.

    Yup.. the answer is we are whole brained. (well.. that's another debate)

    How the idea started:


    It makes me wonder how many other myths are being believed as scientifically proven facts.

    It is also a common myth that we only use 10% of our brains.

    I'm sure I heard that one at the KH many times.

  • Dis-Member

    In the KH and out of it..

    "You know, you're only using 10 percent of your brain. Just imagine what you could accomplish if you used the other 90 percent!"

    Chances are high that you have heard someone make a similar comment at some time or another. The popularly and widely spread belief that we only use or have access to 10 percent of our brain's power is often used to speculate about the extent of human abilities if only we could utilize our brain's full capacity.

    In reality, this claim is 100 percent myth. We use all of our brain. The only instances where there are unused regions of the brain are those in which brain damage or disease has destroyed certain regions.

    The Origins of the Myth

    Researchers suggest that this popular urban legend has existed since at least the early 1900s. It may have been influenced by people misunderstanding or misinterpreting neurological research. The 10 percent myth may have emerged from the writings of psychologist and philosopher William James. In his 1908 book, The Energies of Men, he wrote, "We are making use of only a small part of our possible mental and physical resources."

    The myth has perpetuated much like other urban legends. Well-intentioned people such as motivational speakers or teachers often cite the 10 percent myth as a way to demonstrate that all people should strive to live up to their full potential. Unfortunately, less well-meaning people have also used the myth to promote and sell products and services that they claim will unlock your brain's hidden potential.

    Debunking the 10 Percent Myth

    Neuroscientists point out a number of reasons why the 10 percent myth is false:

    • Brain imaging scans clearly show that almost all regions of the brain are active during even fairly routine tasks such as talking, walking, and listening to music.
    • If the 10 percent myth were true, people who suffer brain damage as the result of an accident or stroke would probably not notice any real effect. In reality, there isn't a single area of the brain that can be damaged without resulting in some sort of consequence.
    • We would not have evolved such large brains if we were only using such a tiny portion of them.
    • The brain uses approximately 20 percent of the body's energy. It would make little evolutionary sense to have such a large portion of our energy resources utilized by such a tiny amount of the brain.
    • Brain mapping research has yet to find any region of the brain that does not serve a function. "Numerous types of brain imaging studies show that no area of the brain is completely silent or inactive," wrote Dr. Rachel C. Vreeman and Dr. Aaron E. Carroll in a study of medical myths. "Detailed probing of the brain has failed to identify the 'non-functioning' 90 percent."

    Unfortunately, the 10 percent myth remains both popular and persistent. It has been repeated in popular culture in everything from advertisements to television programs. The next time you hear someone claim that we only use 10 percent of our brains, you'll be able to explain why this statement is not true. Not to say that human beings don't have amazing potential – we just use 100 percent of our brains to accomplish these remarkable feats.

    Well, thanks for this very interesting bit of info.

    I never could keep straight whether I was "right brained or left brained" so am glad to know there is nothing to that.

    I do know that I didn't use more than 10 percent of my brain when I was a Witness, however, because they "did all the research for me."

    Without thinking about it, lace your two hands together. They will come together naturally with either your right or left thumb on top. Left=right brain dominance and vice versa.

    Are you an artist or an engineer?

  • sparrowdown

    Definitely artist.

  • prologos

    artistic engineer. love 'eye-ball-engineering, using 2 eyes, 2 sides of the brain obviously, and finding it lucrative. butmy right side of the brain is under- trained, I find it awkward to hammer in a nail swinging the hammer left handed.

    butmy right side of the brain is under- trained, I find it awkward to hammer in a nail swinging the hammer left handed.

    Likely because you're right handed

    10% of a JW's brain is used in the K.H ? I would have thought the percentage was far lower.
