Do we only use 10 percent of our brain?

Do we only use 10 percent of our brain?




Most of the people still believe that using 100 percent of our brains is not possible at all. one of the most common beliefs about the brain is that we only use 10 percent of our brain, and if surprisingly we become able to use 100 percent of the brain we would be a superhuman with incredible capabilities.

The origin of these beliefs is not known to us, but there are so many different hypotheses about this subject.

According to one of the most famous hypothesis, the book introduction which Lowell Thomas, an American journalist, wrote for the book ‘How to win friends and influence people’ by Dale Carnegie expanded this belief. He wrongly quoted William James: “a normal human can only use 10 percent of potential mental capability.”

Another hypothesis attributes this belief to an invalid quotation from Albert Einstein, it has claimed that Einstein knew his mental power because of using more than 10 percent of his brain!  This quotation has not any valid source.

The third hypothesis believes that this belief is based on misleading scientific findings. For example, Wilder Penfield, the famous neurosurgeon, introduced a new part of brain named ‘silent cortex’ which according to his research it had no reaction against electrical provocations. But today this part is called ‘association cortex’ and is known as the main factor of the most complicated mental processes.

According to a survey which took place in 2014 between 242 Dutch and Indian school teachers, 48 percent of the British contestant and 46 percent of the Dutch agreed with that belief. In another survey which has done by Michael J Fox Foundation for Parkinson’s Research in 2013 in America, 65 percent of contestants announced their agreement.

To many people, this popular belief is not only probable but also deceptive. Most of us believe that we can only reach success if we work hard.
