>I think the only valid interpretation of the IQ test is that you are good at solving some riddles and spotting patterns. In no way, it can be used as a generic metric of who is better or worse.

Correlations are what matter. It just so happens that success at solving such seemingly trivial riddles is correlated with important tasks such as coding and life outcomes. If IQ didn't correlate with anything there would be no reason to have IQ tests. It would be as useful as astrology.
