"...highly unionized Michigan being the one blue exception to the rule..."

Another thought regarding IQs and their relation to heredity. Why does the white population of Utah have a median IQ 17 points higher than that of West Virginia? The white population of both states is dominated by persons of British descent, although Utah's Mormon majority has a strong English component, due to the Yankee roots of the LDS church and the fact that early missionaries heavily evangelized England. West Virginia, OTOH, is dominated by the Scots-Irish. I don't imagine there is much genetic difference between the two groups.
