Religion and science are the subjects of another article in the New York Times. This one focuses on Scot Atran's views about why people believe in God. In particular, it examines competing explanations among scientists who see belief in God to be a natural result of the brain's processes.
Atran's education included a stint working with Margaret Mead, which led him to wonder whether belief in God is the default position. Perhaps belief in God requires less effort than disbelief? The article examines this question in good depth, and will lead you wanting to read more of Atran's work, as well as that of Justin Barrett and the other scientists quoted.
