Comment: It's sometimes a shock to remember that in most natural things (like human intelligence) it's all bell curves. So, for it to be a normal bell curve, there must be a few folks in the far lower left hand spot on the curve where it tapers off to nothing. Sigh. Of course that means that there are also a few genius types on the far right side of the curve, but I doubt any of them show up at the flat earth meeting.
