Suffering leads to belief in god

It seems misery loves supernatural explanations…

Excerpt from “Bering in Mind”’s  God’s in Mississippi, where the gettin’ is good:

…. In an article soon to be published in Personality and Social Psychology Review , Harvard psychologists Kurt Gray and Daniel Wegner argue that human suffering and God go hand-in-hand because our evolved cognitive systems are inherently unsatisfied with “sh*t happens” types of explanations (that is to say, reality). The main gist of their argument is that, since we’re such a deeply social species, when bad things happen to us we immediately launch a search for the responsible human party. In being morally vigilant this way–in seeking to identify the culpable party–we can effectively punish blameworthy, antisocial people, thus preserving our group’s functional cohesion and preserving each individual’s genetic interests. That’s all fine and dandy, say Gray and Wegner, when someone punches us in the face, steals from us or sleeps with our girlfriend; but when our misfortune is more “abstract” (think cancer or a tsunami) and there’s no obvious single human agent to blame, we see the hand of God.
