A big thing to consider is the fact that everyone got online all the time during the enshittification phase of OKC - it wasn't just OKC's userbase, but it was the median of the whole internet that got dumber and less sophisticated/more basic. When OKC was great, the random median many-hours-on-the-internet-every-day user was a lot better than it is today. Now that's just a median member of the general public, thanks…
When I first got online the average user’s IQ was no joke north of 120. Now of course it’s around 100. Someone needs to come up with a pithy term for how a subpopulation’s average value for any attribute approaches the population’s average value for same as the subpopulation’s size approaches that of the population. It’s conceptually a simple, even trivial, notion, but it’s cumbersome to talk about. That’s also why u…
> for a wide class of probability distributions, no more than a certain fraction of values can be more than a certain distance from the mean. Specifically, no more than 1/k^2 of the distribution's values can be k or more standard deviations away from the mean.
IQ is (if I recall correctly) normally distributed with a standard deviation of 15. So for a distance of 1.3... standard deviation (i.e. a distance of 20), you can't have more than 1/1.3...^2 = 56.25% of the population so far from the mean (below 80 or above 120), or 28.125% _above_ 120.
