There aren't 6 point differences between France, China, Japan, and the USA. It's more like 2 points. And if 2, or 6 points could double construction costs, then in the poorest countries like Africa everything would have to cost something like 100x more, which is definitely not the case.

- narag 9y agoSomehow you put the double construction costs in the middle of "IQ difference" and "we can't do it". Why?
- ShannonAlther 9y agoThis is only true for certain scales relating IQ to construction costs. The average IQ in Africa is, what, ~15 points lower than America? Suppose the first 2 points increase construction costs by a factor of 1.5, and each subsequent 2-point reduction by a smaller factor, until you reach some limit (IQ average too low to be realistic, NGO aid, something like that).
