Lmao the second anyone mentions IQ to me outside of a psychiatric evaluation I know I can tune out whatever else they have to say.
I like IQ as part of teaching the vocab words “validity” versus “reliability.” The test is “reliable” in that you’ll get the same scores consistently, but is it “valid” in that it claims what it purports to measure?
It’s also a good way to talk about the math behind standard deviation - very relatable for the “empirical rule.”
