Not sure how this is on the front-page. The article chases to debunk something that is only used as a metaphor for the capacity of the mind. IMO the idea that we only use 10% of our brain is oversimplified way to get the attention of a child when conveying the minds power. For example, you only activate 10% of your brain when reasoning a difficult math problem, or recalling a memory. I don't think anyone ever asserted that 90% of your brain is turned off.
