Significant correlation (Jacoby)

Regardless of how fundamentalists fine-tune their beliefs, there is unquestionably a powerful correlation between religious fundamentalism and lack of education. Approximately 45 percent of those who have no education beyond high school believe in the literal truth of the Bible, while only 29 percent with some college—and just 19 percent of college graduates—share that old-time faith. Secularism, skepticism, and acceptance of mainstream science all rise with education; two thirds of college graduates, but only about one third of high school graduates, believe that living beings have evolved over time—with or without the guiding hand of a creator.
