IQ is an ordinal score in that it’s relationship to outcomes of interest is nonlinear, but for the most important outcomes of interest, e.g. ability to solve difficult problems or income or similar, the relationship between IQ and success at the outcome is exponential, so you’d be seeing accelerating returns for a while.
Presumably fundamental physics limits how far these exponential returns can go, but we seem quite far from those limits (e.g. we haven’t even solved aging yet).
