Уровень доходов, также, естественно, находится в прямой зависимости от величины IQ, what a surprise.
What I found interesting to ponder was the fact that the world's poorest countries were also the ones with the lowest IQ average, generally speaking. Does the fact that they have been poor for generations mean that their IQ average is low because they are poor or are they poor because they have a low IQ average? <...> Given that most of the lower ones are African nations I wonder if poor nutrition through drought after drought would affect IQ overall. I guess that would come under your "been poor for generations mean that their IQ average is low" theory. - может оно, конечно, и так.
В общем, Bell Curve в полный рост. Факты "с душком", как выразились бы наши левые защитницы всеобщего равенства и братства:)
