I think the assumption that degree difficulty (ie signalling cost) depends only on individual IQ (i.e. is constant with respect to A) cannot be correct. Degree difficulty must be higher in higher-intelligence societies (holding all else equal). So K is some increasing function of A.

Basically it’s somewhere between “top 30% get a degree regardless” and “whoever is smarter than x gets a degree, where x is constant for all societies”

Narrowly specific and hypothetical models are the best models, I say. Fascinating read!
