Here’s Chris Mooney, who has made it his mission to chronicle and then explain why the GOP is resolutely anti-science, summing up his life’s work rather succinctly.
If you want to go deep on this subject, Mooney recently wrote up a study that explains why conservative antipathy to science is about ideology rather than education or intelligence:
… some cultural groups, aka conservatives, have a unique fallout with science for reasons tied up with the nature of modern American conservatism, such as its ideology, the growth of its think tank infrastructure, and so on.
