Lucky Lucy

Lucy, starring Scarlett Johansson and Morgan Freeman, directed by Luc Besson, opens today.  Don't know much about it, but the poster says "The average person uses 10% of their brain capacity.  Imagine what she could do with 100%." (One thing she could do is remember the plot of Limitless from 2011, which had the same premise.)

I've always been intrigued by this weird urban legend that we only use 10% of our brains. Though it makes no sense, I've been hearing it pretty much all my life.  I've even met a number of people who believe it.  And it keeps popping up in popular culture (where at least it can lead to a fun, if absurd, plot).

Considering there are pretty easy sources available (in addition to common sense) that refute this claim, I can only conclude that people are using less than 10% of the capacity of their computers.
