Do Humans Use 100% of Their Brains?

PaShawnda Briley

Where did the persistent statement that humans use 10% of their brains originate and is it valid? It was first coined by William James, a philosopher and psychologist. Some professionals have even stated even lower percentages, like Margaret Mead saying that we use 6% of our brains (3). If this statement is true, it implies that humans could behave very differently and perhaps with greater thought and purpose. If the statement is a fallacy, it supports the brain equals behavior theory, such that the brain is not harboring unused capacities and behaviors.
