Luckily, we can easily test how much IQ matters by looking at the relationship between IQ and health, wealth, educational achievement and so on.

The fact that IQ test scores are somewhat useful as a ranking mechanism amongst a cohort is completely consistent with it being just being a collection of standardised tests calibrated to score in a particular way, not an actual "thing" where apparent subtle generational changes might represent genuine changes to our physiology or intellectual potential and not just inconsequential differences in our preparedness to solve paper puzzles.
