In TCS:

Murray’s analysis reflects IQ-ism. That is, it reduces human talent to a one-dimensional measure, IQ. One problem with IQ-ism is that it does not explain how people come to acquire particular talents, in chess or art or salesmanship. If one really takes seriously the one-dimensional concept of IQ, then the clay of a high-IQ child could be molded into a genius in any field. Yet many otherwise-talented people are severely limited in some dimensions. Even within a specific subject such as mathematics, different sub-fields come more easily to different experts. I am willing to talk about IQ as a measure of general ability. That does not make it the measure of ability.

There’s a lot more.
