The observation is that above roughly IQ 70 the test is not even correlated with SAT scores. And below 70 one does not need a test to see that.

Is there really any doubt that 80 IQ people are represented less than 110 IQ people in industries like medicine, law, or engineering? If there's really no correlation in SAT scores, I wager that says more about that test than it does about IQ.

  Read the article. This is his point about circularity this is literally one of his examples. If IQ measures test taking acumen and there are fields that are gate kept with tests, you will see a correlation with IQ.

    I doubt the skill of test taking is unrelated to aptitude in those fields, or any other field in which it's important to learn a great deal of information from books and to keep that information in mind for rapid recall during high pressure situations 'in the field.' Law or medical school is certainly harder for halfwits to get through, but that doesn't mean there's anything wrong (in that respect) with that schooling. Rather, it reflects the complexity and importance of those fields. Edit for response: I don't know anything about the MCAT in particular. However I'm confident in saying that the class of people unable to perform well in any sort of test that requires reading and recalling large amounts of information (as learning medicine surely requires, no matter how you structure the education system for it) should find a career outside medicine.

      The MCAT is a difficult test. It is not clear that the difficulty of the MCAT is the same difficulty as practicing medicine. You can't test that question without having doctors who don't do well on the MCAT.

  The correlation comes from low scores. Moreover, above 70 IQ is not even well correlated with itself as variability between results for the same person is like 20%.
