Journalist explaining statistics

I would call this explanation, well, below average:

MATH, HORRIBLE MATH
[…]
Take that bit about the bell curve of IQ. It’s an unpleasant fact that half of all people are of below average IQ. It’s also true that half of all people are below average height, weight, and everything else. And the other half are above average. You know why? Because that’s what “average” means.

The italics are in the original text (they are not mine). May be alternative facts include alternative definitions of statistical terms. It is ironic that the title of the section is about bad math.
