It is perhaps for this reason why so many myths about how the brain works persist, despite plenty of evidence to the contrary. One of the most common of these myths is often referred to as the 10% of brain myth, or the idea that human beings really only fully utilize a tiny percentage of their brains power and potential. The popular and widely-spread belief that we only use or have access to 10% of our brains power is often used to speculate about the extent of human abilities if only we could utilize our brains full capacity. People often experience the shortcomings of their own mental abilities, such as failing to understand a complex math problem or forgetting some vital piece of information. It is perhaps because of this that people frequently feel they possess some untapped potential, if only they could unlock that inaccessible portion of their mind. In reality, the 10% claim is 100 percent myth. You use all of your 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% 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. Movies depict characters capable of remarkable feats when the supposedly unused 90 percent of their brains are unlocked. 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 brains hidden abilities. 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 isnt 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 a tiny portion of them.The brain uses approximately 20 percent of the bodys 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 to Hollywood blockbusters such as the 2014 film Lucy starring Scarlett Johansson and Morgan Freeman.?? The next time you hear someone claim that we only use 10 percent of our brains, youll be able to explain why this statement is not true. Not to say that human beings dont have amazing potential; we just use 100 percent of our brains to accomplish these remarkable feats.
