<p>In fact the list is from wikipedia, here’s the link: [IQ</a> and the Wealth of Nations - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/IQ_and_the_Wealth_of_Nations]IQ”>IQ and the Wealth of Nations - Wikipedia). From a cursory glacne through the article, it’s clear that the list is by no means an authoritative one. So I wouldn’t advise anyone to take it particularly seriously.</p>
