Earlier quoted context omitted.
What does IQ have to do with intelligence? (Please forgive the flippant response. I believe it cuts to the core of what the parent was intending.)
Is it a serious question? IQ tries to quantify the positive correlation between the results of all intellectual tasks a person takes (AKA positive manifold).
I wanted to highlight that we're actually looking at a trio of concepts: intelligence, IQ, and value. Strongly correlated concepts, yes, but also meaningfully distinct!
