That the scores on a given IQ test are occasionally renormalized so that the mean is 100 has no bearing on whether "IQ is a statistical distribution", whether intelligence or whatever the heck IQ measures can be measured absolutely, or on the validity and meaning of the previous statements by E…
I find it interesting that you are basically saying the same thing, even if the reply you are confused by simply made some assumptions you were not able to make and was a bit less precise. It’s interesting how people will say things like “This is wrong and confused in every possible way” even though it’s not, making it and them in turn the ones “wrong and confused in every possible way”. Maybe if we are a bit more ge…
