I agree with you about the Bell Curve stuff, I believe that's where you're coming from, I think where you're coming from is a good place, I don't agree with you (or rather: think you're way overstating) the diminished role of IQ in science and medicine, but we agree on the important things about IQ and how it has mostly a malign role on message boards so we don't have to hash it out too far. I just don't want to concede the IQ frame to race trolls.
My thing is just: there's plenty of room to believe IQ is totally legitimate without giving an inch on what people who refer to "IQ-deniers" when what you always suspect they really mean is "race/IQ-deniers".
I don‘t disagree with you. This is basically Eric Turkheimer’s position and he has done an excellent job, and amazing science working within the field of Behavioral Genetics expelling and debunking all the racist pseudo-science of the likes of Plomin (see e.g. his review of Blueprint, 2019).
If you want to see where the tide is turning though, I do recommend e.g. Jay Jospeph. He recently reviewed Turkheimer’s latest book[1]. He is more attacking Behavioral Genetics as a whole (in particular heritability of schizophrenia) and debunking twin studies, and as such doesn’t write too much about doing away with IQ entirely. Despite the difference in opinion Joseph still cites Turkheimer extensively in good light in his own review of Plomin’s Blueprint[2].
I think these debates around the philosophy of science are important and worth following, at some point these meta-debates and book review somebody is going to declare the death of the IQ (or more likely of psychometrics), just like Jay Joseph is declaring the death of Behavioral Genetics today. But I think in the next 10-20 years we will be seeing more and more of neuroscientists who very casually (almost as if it is a non-importance) that the whole notion of IQ is a myth.
