I want to share this as well: The Globalization of the IQ Wars https://www.jacobinmag.com/2018/04/race-iq-charles-murray-global-bell-curve https://www.jacobinmag.com/2018/04/race-iq-charles-murray-gl... Please don't believe that IQ related studies are mainstream in social and psychological literature: they are very contested. That said, citizens and policy makers should decide if trusting them or not.

Contested yes, it seems they are downright detested. No one wants to talk about this. In the west because of how political anything related to IQ is, I doubt much will happen here. It's more likely China will take the lead in the area of research.

  I think the problem is, you can't really quantify something that isn't clearly defined. Intelligence is very badly defined. So IQ is the kind of fundamentally flawed science that lends itself very easily to politicization - just like eugenics before it. Leading this area of research is really just a waste of everybody's time - just like leading the 'area' of phrenology. There's lots of interesting scientific work about definable attributes of thinking beings - like problem-solving ability, or memory, or spatial sense. These don't suffer the same 'politics' problem, since their topics are clear and possible to concisely express.

    I've always thought the idea of trying to represent "intelligence" in all of its multi faceted glory with a single number is just plain silly.

      I've always felt uneasy about the whole concept of IQ but never really been able to put it into words. I think you've hit the nail square on the head here wrt my thoughts on the subject. Thanks!

      all of its multi faceted glory with a single number Think of this number as the first principal component, generated from all these different things. Talking about it doesn't imply that other directions don't exist. But it's not so strange to work on the leading effect before worrying about sub-leading ones.

        As a sort of reductio-ad-absurdum, imagine if somebody came up with 'GQ', or 'goodness quotient'. It's absolutely the case you could use a battery of tests to check how likely somebody is to do anti-social behaviour. 'Goodness' is about as conceptually well-defined as intelligence.

        Isn't the chinese government working on that? :) But more seriously, yes, to figure out how useful the first component is, you want to know something about how much bigger the first eigenvalue is than the second. For the case of IQ, my understanding is that the answer is "quite a lot". The best studies are from the army testing people and assigning them to roles (and seeing how they do). And it seems pretty hard to come up with tests which are better predictors than IQ. I think the one perpendicular component worth measuring for some jobs is manual dexterity? And eyesight, which is a rare thing anti-correlated with IQ, because of teenage bookworms we think. (That said, note that this isn't the whole population, they set a floor by only accepting reasonably healthy young men etc.)

        The chinese government is working on it - but they are, at the very least, not convinced it is science. Not to mention, most people are horrified. I don't doubt that IQ, like Social Credit, is a useful administrative tool. However, something being useful from an administrative standpoint does not make it scientific. It also doesn't make it desirable. There are very many things that are absolute inconveniences from an administrative standpoint, that are absolutely necessary from a human one. Rights, basic freedoms, and so on.

      But it can be useful. I think of it like BMI. Lots of flaws, but the most effective way of measuring healthy weight in populations. IQ is similar. Lots of flaws, but how else do you measure intelligence? There are lots of correlations with IQ. Not using intelligence as a measure is silly. I think it’s just something that uncomfortable, so I like to pretend it doesn’t matter. If I’m starting a software company, it is useful to have a measure of raw intelligent. Not to he exclusion of other characteristics, and maybe not even the most important. But certainly useful data for planning. I do think it’s silly to say the totality of intelligence is represented in a single number. But it can be useful. Like credit score. Lots of flaws, but what is a better measure? https://www.sciencedaily.com/releases/2012/03/120329142035.htm https://www.sciencedaily.com/releases/2012/03/120329142035.h...

      In general I agree. For any gene, you'd expect those alleles which give their holder an advantage in the environment they inhabit to be passed on to their descendants, including those which influence brain development. But if their environment ever changes, or they're put into a different environment, they might find themselves at a disadvantage compared with those native to their new environment. Environment is important as it determines which traits and which genetic variants are selected for, and genetics is important as it determines which environment people will flourish in. So if you only use a single number to measure intelligence, it it will only be a good predictor for a single environment.

  Go to Stormfront. They discuss IQ to death. If we wanna talk about education we should talk about stuff we CAN change like fast-tracking talent, project based education and smashing the absurd social structures we allow to fester due to age-segregation. There's tons we can do as opposed to wasting time on stuff we cant like change genetics.

    But one day, in the not too distant future, we will be able to change genetics. And when that day comes, if we have taken the time to understand the relationship between intelligence and genetics, then we can finally take permanent measures to equalize humanity by giving everybody as much intelligence as possible.

Actually, the measurement of IQ and it’s predictive ability for things like job performance and life outcomes are some of the best replicated research in all of psychology and the social sciences.
