It does predict they should be rare but extremes are rare. What is your theory for how to understand these results?

- gwern 7y agoMensa-level extremes are not rare at all. They're something like 2% of the population (probably even more when you consider they allow multiple retests and other non-IQ tests). > What is your theory for how to understand these results? There is nothing to understand. It is purely an artifact of their sampling process. There is no reversal and no mystery. IQ simply correlates with better performance and health as far up as we can measure it into samples like TIP or SMPY, period, and 100% consistent with mutation-selection balance. Mensa attracts losers, and those losers self-select even further into a survey asking about self-diagnosed problems, and these researchers were too lazy to do a good study and too dishonest to discuss forthrightly all the reasons why one knows a priori their results only demonstrate that sampling from Mensa is a really bad idea (I say 'dishonest' because they do not mention any of the very well known contrary results and I am also told these points were all brought up to them before publication and they refused to address any of them).
