I never claimed that intelligence is nothing. I said that the IQ measurement is itself not worth much except as a general guide in fairly broad ranges.
Intelligence is certainly something. It is relevant. But it is not precise, and is useful, as I said, only in the broadest strokes. And like all psychometrics, the manner in which it is measured is itself not stable.
But comparing intelligence to mass or any other physical measurement is a non sequitur. Mass is precisely measurable with perfectly repeatable results, and has perfectly repeatable interactions.
