From what I can gather, he’s saying all other evidence points to a large number of highly specialized mental functions instead of one general intelligence factor, and that psychologists are making a basic error by not understanding how to apply and interpret the statistical tests they’re using. It’s the latter which I find particularly unlikely (not impossible though).
You might be right. I’m not really competent to judge the first issue (causal structure of the mind), and the second issue (interpretation of factor analytic g) is vague enough that I could see myself going either way on it.
