> I’ve worked with governments and companies in quite a few developing countries around the world where the average IQs are between 1-2 standard deviations below 100, and that problem is right up there with corruption when it comes to what’s holding these countries back. Also consider how much brain drain contributes to this. Anyone in those countries who is smart enough to recognize this will just emigrate to more developed countries, and their home country will never get to benefit from their (relatively) smarter people. So the country's IQs might be just about average, but if their top deviation is constantly leaving...you have a negative feedback loop through no one's fault.
