You are perpetuating a myth. While Dr. Einstein may or may not have actually made this statement,
the statement that people use only ten percent of their brains is false.
Brain imaging research techniques such as Positron Emission Tomography (PET) and Functional Magnetic Resonance Imaging (FMRI) clearly show that the vast majority of the brain is in use at any given time. Although certain minor functions use only a small portion of the brain at once, any significantly complex set of activities (i.e., reading, typing, watching TV, eating, having sex, et cetera) or thought patterns (i.e., planning, problem solving, concentration, remembering, et cetera) indeed use many parts of the brain. Just as people do not use all of their muscle groups at any one time, they also do not use all of their brain at once.
The myth presumes that brain functions are extremely localised; that the utilized parts of the brain are indeed very, very small; and that the remainder lies dormant, just waiting to be used. Actually, the parts of the brain that are in use are scattered all over the brain, making the entire brain necessary. This is demonstrated by the fact that when any part of the brain is traumatised or removed, the person so treated suffers from loss of memory, perception, and motor function.
Besides,
Dr. Albert Einstein was a Theoretical Physicist, not a physician, and certainly not a brain surgeon! Plus PET and FMRI scans were invented long after he had died. Thus, he had not the expertise, nor the means, to determine the extent to which humans use their brains.
