>>14254165The average IQ of a country matters little unless they can advance the theoretical knowledge behind science, that's where countries get their real power, as that's what gives them advancements other countries don't have.
For instance Russia may not be very smart on average, but their science was dominated by Jews for a long time, which is what gave them the ability to compete with the US in STEM in the first place. China absolutely sucks as science is the thing, though I will admit they have some interesting engineering projects like the north south water transfer, but they don't "compete" in the field of STEM so much as they just listen from the sidelines.
