Only 32 percent of Republicans believe in evolution. And most Democrats (51 percent) don’t know both that the Earth goes around the Sun and that it takes a year to do so.

These are just some of the findings that emerge from a closer analysis of the underlying data in the new National Science Foundation Study. A lot has been written about the drop in the proportion of Americans (55 percent) who think that astrology is “not at all scientific” and about the 26 percent of the population who don’t know that the Earth goes around the Sun. Yet what has entirely escaped comment are some more interesting findings that can be gleaned only from crunching the numbers.
