You should really look into the history of IQ testing. In its infancy (in the United States) it was used to show that Italian Americans and Irish Americans were fundamentally inferior to Anglo Americans, because those populations had lower IQ scores. Lo and behold, those scores normalized as those populations became more assimilated.

If you had written this comment (on paper) early last century you'd be telling us that the liberals refuse to accept that Italian immigrants are inferior to their Anglo counterparts. Such ignorant liberals!
