I find Bloom's theory pertinent to this discussion anyway. I see a connection between believing in God and believing in intelligent design. If people are naturally predisposed to look for design, planning, meaning and a superior order in things, believing in God is just a consequence of that.
George Steiner wrote a book that explores this matter from another perspective: Nostalgia for the Absolute. In it he explains how Marxism, Freudian psychology, New Age, etc., are just ideas people are using to replace the idea of God. Steiner argues that modern people are living in spiritual emptiness and looking for something that will fill that void.
