Negative IQ would be more than six sigmas away. I don't think the distribution would hold till tail that far 🤔

I was wring abou the 13 billion. It's more like 76 billion. But you can reach any number with enough tests.

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.
