Could also be due to racial factors regarding the racial makeup of East vs. West along with the impacts of the war of demographics. The Germans were humiliated after the war with Jews pushing black marriages on the women. Tons of rape from non Germans etc... Still an interesting study but still with potential flaws unless those variables were hammered out. Still, is that 1 standard deviation the 20%? Though that would imply more like 33%+.

Personally, I happen to think it's more like 50/50. Nature should not be so easily discounted by most people.
