Many studies have shown that groups with higher intelligence or more education have significantly more atheists.[19] A recent meta-analysis of 39 eligible studies from 1927 to 2002 was published in Mensa Magazine, and concluded that atheists are more likely to be of higher intelligence than their religious counterparts.[20] According to an article in the prestigious science journal Nature in 1998 the belief in a personal god or afterlife was very low among the members of the U.S. National Academy of Sciences. Only 7.0% believed in a personal god as compared to more than 85% of the general U.S. population.[21] A 2012 WIN-Gallup International poll found that people with college education were 16% less likely to describe themselves as religious than those without complete high school education.[18] This may suggest that the more intelligent subjects are more unlikely to believe in god or supernatural powers. An alternative interpretation is that having completed the kind of education that makes you likely to do well in IQ tests is also likely to have either divested you of religiosity or at least made you less susceptible to the kind of beliefs in a personal god which characterise Christian fundamentalism.
