When God sanctions violence, believers act more aggressively

A recent study from Psychological Science argues that there is a direct relationship between violent behavior, and beliefs/rhetoric about a violent diety (whether he/she is referred to as "God", "Allah", "Yahweh"...).

This is a topic that's been on my mind since I first read Martin Marty's work on the Fundamentalism Project.   How much does fundamentalism share in common across world religions?  The study above looks at one very interesting aspect of the relationship...fundamentalism and violence.  You may find it very interesting...I did.
