> 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.

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.
