Thanks to Kate and Hannah, here’s a link to a detailed (and perhaps more than usually accurate) survey of religious belief in the US. The detailed tables are fascinating. One example: with respect to educational attainment, broad belief in God went from 82% for “High school or less” to 73% for “Post graduate”. However absolute certainty about God went from 72% to 53%. (Of course as Flanagan points out, many believers don’t actually care very much about whether their belief is well grounded, or strongly held, or even if it’s true….)
