Myth: We use only 10% of our Brain

The Evidence:

  • The evolution of the human brain was only possible because it provided survival advantages and they must have been great since it consumes over 20% of the oxygen we breath while it only weighs 1,5% – 3% of our body weight. If we were to use only 10% of our brain than it would be extremely wasteful and such a disadvantage would be something selected against.
  • Brain damage to far less than 90% of our brain would render us either physically dead, brain dead, or severely impaired. This shouldn’t be if we only use 10% of our brain.
  • Strokes and head traumas that affect much less than 90% of the brain leaves people with serious deficits in functioning.
  • Brain scans show that we use most of our brain even while performing simple tasks.
  • Brain areas that are unused due to injuries or disease either degenerate or are taken over by neighboring brain areas.

Bottom Line: If we have more brain mass, it will be used; if it is not used, it will be discarded; and if we don’t have more of it, natural selection might select for it.

Myth Origin: William James, an American psychologist from the 19th and 20th century, said the average person only achieves a fraction (10%) of their intellectual potential. Misinterpretations have transformed potential into actual physical brain usage.
