@jokeocracy @ClarkHat Pretty sure that article makes corned beef hash of the statistics. @themattsimpson, wanna ring in?
@jokeocracy @ClarkHat @themattsimpson eg: you can't filter a gaussian like that and treat the new distribution as a gaussian. It's skewed.

@ClarkHat Caveat: this is done w/o pencil and paper or anything. But start with a standard IQ bell curve. Now separate all the 130+ people. -
@ClarkHat Your new distribution looks like a sharp spike near 130 and falls off pretty fast. The variance goes way down: mostly near 130. -
@ClarkHat Now throw out what you know except mean and s.d. You are now pretending you have a gaussian w/mean ~135 & small s.d. -
@ClarkHat But right-hand tail of this gaussian falls off much faster than tail of the real distribution. You systematically underestimate... -
@ClarkHat ...presence of ultra-high-IQ participants (those in the far right-hand tail). No conspiracy here, just bad statistics. -
@ClarkHat Second disclaimer: I have never actually taken a course in statistics, though I have taught several. -
