National IQ Has Increasing (Log-Linear) Returns
Returns to national IQ are log-linear, which looks crudely like increasing or exponential returns, because human capital relationships are generally multiplicative rather than additive—tied to Adam Smith's pin factory and better organization of the division of labor between people.

“There's something multiplicative... we have multiplicative not additive effects when we are increasing brain power. I suspect it does have something to do with a better organization of the division of labor between people, which ends up happening something close to exponential effects on productivity.”
