I'm not talking about the normal distribution being valid at some value. Since it's a continuous decaying function in either direction, it'll be kosher at any real number. I'm talking about the hypothesis that IQ will be normally distributed not holding at that far deviations.
I was wring abou the 13 billion. It's more like 76 billion. But you can reach any number with enough tests.
