I see your point but it also implies that Europe breeds the stupid while US allows them to extract themselves from the gene pool.. not a very nice perspective for me (as an European)

[hectorlorenzo]

According to the article, extracting stupid people from the gene pool won't affect the ratio of stupid people present in society. σ remains constant no matter what.

Yes good point. Now, in the US, some of the stupids seem to extract a lot of other/innocent people from the gene pool with them...
