My post was tailored around the kinds of people who say stuff like “Cue the IQ deniers” and who very carefully insinuate not accepting fraudulent data from desecrated IQ scientist Richard Lynn is “denying facts”. And as such I used this on the nose speech.

If I was having this conversation with you (which we’ve had in the past) whom I believe is a Gloomy Prospector (a la Turkheimer) as opposed to my GPs Bell Curvers I would have been more careful with my wording.

Before I continue I do want to note that a lot has changed since the Gloomy Prospect‘s heyday in the late 1990s and early 2000s. Back then people like Turkheimer were still pushing them selves to become the mainstream pshychology (although the writing was pretty much on the wall for the likes of Plomin, and before him Jensen, Lynn, et. al.). I want to make it absolutely clear that I respect (nay, love) the work Turkheimer et. al. have done in getting us here. He and people like him are true scientists. But now his Gloomy Prospect is being challenged from the left still, and I would not be surprised that in 20-30 years IQ will have gone the way of the Aether.

That said, I want to correct you, IQ tests are being used as one of many important clinical and diagnostic tools, in particular the subtests. IQ has not been used in diagnostic since DSM-III I believe (I may be wrong; I don‘t have a DSM-III handy). Many clinical and developmental psychologists still use subtests of IQ, but very few compute the actual IQ. Some social psychologists still compute IQ of and try to find some correlation to this and that, but when I read those research I get the vibes from studying the effect of weightlessness on tiny screws[1]. If I were to guess (and Turkheimer would disagree with me on this) this is purely because of momentum, and has nothing to do with the scientific value of IQ. IQ tests are extremely robust, have been thoroughly standardized, and whole generations of clinical psychologists have been extremely well trained in administering them.

Now, I don‘t think my GPs have read beyond the words Gloomy Prospect in my post, and I don‘t think bringing some critique on Eric Turkheimer from the left is gonna open the eyes of people who are still promoting the Bell Curve 30 years later.
