      Yes. We have way too many ppl on 6 SD and 7 SD in the world for the distributional assumptions behind IQ to be valid. The distribution for IQ is fat-tailed and skewed (most examples of fat-tails IRL have a skew).

      Replying to @suvyboy @MimeticValue and

      No, it is not fat-tailed. Fat tailed means expectation or higher order moments for distribution do not exist (see, for example Pareto distribution). On issue of skewedness, we don't see too low iq types because they die or locked in the institutions.

      Fat-tails doesn't have to imply mean is non-existent.

      But higher order moment should be non-existent, otherwise it means there is no fat in the tail. And again, we have normality tests, so we can be pretty sure whether IQ curve is a indeed Gaussian.

      Replying to @MimeticValue @ovchinnikov and

      Could that even be on an absolute scaling? Even if you used a neural network model ( e.g. system of coupled equations), you still have uncertainty induced in the output response. It seems the notion of expectation value makes more sense than a 100% determinism. Imho.

      A ratio scale measurement of intelligence seems possible, but one needs something more direct than standard IQ tests for this. One option is chronometric tests. Read e.g. Jensen's book about this angle. Neuroscientific angle probably better but harder. https://www.amazon.com/Clocking-Mind-Chronometry-Individual-Differences/dp/0080449395 …

          I cannot believe that you are STILL arguing with these people about IQ, 24 hrs later! Jensen's book should shut them up and put this to rest already. I don't know how you have the patience for this, Emil

          I wasn't arguing with them, I have them muted, But I saw the message by Michael and he's not muted, so thought I would be helpful. It's a neat book that definitely changed my thinking on the topic.

          Thank you for the book reference. The book and research is unfamiliar to me. It looks like interesting study and could help me with my research/study on general intelligence.
