Sure, but the point is that 180 wouldn't make sense even if the test were perfect. There aren't enough humans on earth for that many standard deviations to exist in the first place. 180 IQ could as well be 2000 IQ, the sky is the limit when the scale makes no sense.
- computerphage 4y agoThat's just wrong? 6 sigma would be IQ 100 + 6 * 15 = 190. 6 sigma is 1 in 506,797,346. So there should be 16 people with IQs that extreme if intelligence is normally distributed. (There's a factor of two somewhere in here for the two tailed nature, but the point stands)
- delecti 4y agoEither I'm misunderstanding the math, or you are. An IQ of 180 is 5 1/3 SD above mean, which is a bit more frequent than 1 in 26,330,254 (which would be 5.5 SD). Half that common because we're only talking about above, and 1 in 50m people on earth is still 160 people. That's not many, but I don't think it's negligible either. https://en.wikipedia.org/wiki/68%E2%80%9395%E2%80%9399.7_rule#Table_of_numerical_values https://en.wikipedia.org/wiki/68%E2%80%9395%E2%80%9399.7_rul...
