I have not seen anyone say this, so I will (apologies if I missed someone's comment). It is not clear that IQ is a good measure of smart.

I'll also note that when I teach Elementary Statistics and ask undergrads for a show of hands of who has taken an IQ test, often in a class of 30 I won't get more than a hand or two. So I guess these studies are administering the tests specially for the study?

I'm also wondering where they're getting all of the IQ stats. I have no idea what my IQ is, and I don't recall ever taking an IQ test in my entire life. Where I came from, it certainly wasn't routine to administer IQ tests.
