So is it true that we only use 10% of our brains and that we have 90% worth of untapped potential just waiting to be unleashed (preferably in terms of cool powers such as telekinesis or mind blasting)?
Unfortunately the answer is no.
Our brains have always been fully utilized – though not all at once – and this 10% is a myth that can be traced back to a comment made by an American psychologist, William James back in the early 20th century.
And it makes sense. According to the article, if we are only using 10% of our brains, then any efforts to remove any parts of our “unused” brains should not affect us at all. Even during sleep, our brains remain active at a eer, sleep mode.
Oh and the Mythbusters explored this and their verdict? Closer to 35% of usage.
Myth Busted!
Rooooooling....
