Science and the Wealth of Nations
J McCormick at Anglosphere.com/weblog reports on the connection between a nation's wealth and its scientific output. Logically, this can fit with the concept of a connection between a nation's wealth and its mean IQ. Links were provided to a pdf report entitled "The Scientific Impact of Nations", and an earlier pdf article from Science entitled "The Scientific Wealth of Nations.
Both articles are worth looking over, after reading the post at Anglosphere.com.
Gene Expression's Godless also posted on this topic. The graphic from the 2004 pdf linked above comes from the gnxp.com article. Gene Expression is one of the relatively fearless blogs that is not afraid to flout the PC Thought Police whenever necessary.
