UGH!  Folklore alert, folklore alert!!

Despite the fact that everyone "knows" this, it is not true.  What the ~15%
value refers to is the fact that only some fraction of the brain is used for
THINKING (or at least higher thought processes).  The rest is still used,
just not for higher cognition.  (Of course the situation is more complex
than this, but that is where the number comes from).

Somewhere along the line, the idea that humans use only ~15% of the brain
for higher thought processes turned into the idea that humans only use ~15%
of their brain, period.  New Age-ism and bad sci fi not withstanding, this
latter concept doesn't hold up.
