Wow, did a takedown of IQ statistics? This should be 🍿
I basically don't trust a pop-stats idea until Shalizi has taken a run at it

Does this argument not similarly disprove the concept of "air pressure?" Many independent molecules lead to a meaningful aggregate measure. humanvarieties.org/2013/04/03/is- infoproc.blogspot.com/2013/04/myths- slatestarcodex.com/2014/08/10/get

Good comparison. The difference is that air pressure *also* has a strong analytical model attached to it derived from first-principles axiomatic models about elastic collisions. If you give me similar model backing via neuroscience first principles, I'd be far more interested.
Judge them by their fruits. Engineering knowledge/Suction pumps were prior to axiomatic explanation. Don't need a theory if what you have works, but attached Hsu's work on the subject arxiv.org/pdf/1408.3421v
