During the Stalin area, the intelligentsia and people with university education were basically killed off. What happens to a country when you remove most of the educated and intelligent people from the gene pool?
I used the conjunction "educated and intelligent". Intelligent people tend to gravitate towards education, formal or informal. IQ tests show that university students score on average 120-130 compared to 100 in the general population. Removing educated people from the common gen-pool in a closed society may have an interesting collective effect.
