IQ tests measure something. But what?
Why is it that people who do very well on verbal analogies tend to do well on tests like the Raven’s Progressive Matricies, an example of which was posted above?
I agree that IQ tests measure something.
But is it intelligence? Intelligence tends to be defined in practice as what is measured by IQ tests, as good an example of circular reasoning as I can think of.
FWIW, I signed up for Mensa some years ago. Took two IQ tests, and they came back with an over 40 point difference. Turned out the higher one was a test where the tester read a long complex essay about an obscure subject, in this case priests of the classical Greek (pagan) religion, and then I answered a lot of questions about the subject.
I guess I aced that one. What nobody asked me about was my reading habits. I’d read a book on the subject about a week before and could probably have gotten about the same IQ score if they hadn’t read me the essay!
BTW, attending Mensa meetings will do a dandy job of convincing a person that if IQ measure intelligence there are a lot of stupid intelligent people out there, or at least at Mensa meetings!
