Evolutionary explanation for atheism?
April 13, 2010
A recent study by Kanasawa published in Social Psychology Quarterly claims a difference of six IQ points (103 for those “not at all religious” to 97 for those with who describe themselves as “very religious”).
The study shows that both education has virtually no effect either way on a person’s beliefs about God, and that atheists and theists have almost identical levels of intelligence. A difference of six points is so small that it is imperceptible in everyday life. To put it into perspective: six IQ points is the same average difference in IQ found between identical twins (such as these two beautiful and intelligent young women).
