On the other hand, human measurements, IQ results and personality test results like the MBTI are not! I was surprised by this because I thought IQ was a measure of general intelligence. But Rose is adamant that intelligence is discontinuous, and shows two profiles of women who score identical at the WAIS test but have completely different results at the sub-tests.
So am I understanding this correctly, the book says that the general intelligence factor doesn’t exist? That sounds like a pretty big claim, given that the concept has received quite a bit of scrutiny and still seems to have emerged with psychologists having a consensus that yes, it really is a thing. Does it cite any supporting literature with similarly broad conclusions (not just “we got weird results from this one test” like the example you mentioned but “based on this it looks like the whole g-factor thing might be toast”) or is this just the author claiming it?
It sounded more to me like it was saying iq is an abstraction that hides a lot of possibly-important complexity. Which is not the same thing as saying that iq doesn’t exist or is useless.
