There a lot of excitable feedback circuits to be discovered on the way down the slope. This looks like one:
Analyzing data from a large, worldwide sample, two Chinese psychologists report people whose countries are more involved with wars and similar conflicts experience higher levels of existential fear, which drive them to greater religiosity. […] Previous surveys have found highly religious Americans tend to be more supportive of war, as well as of torturing one’s opponents. This raises a profound and troubling question: Could it be that armed conflict and intense religiosity are in a mutually reinforcing relationship? […] “The relationship between war and religiousness may be bidirectional,” write Hongfei Du and Peilian Chi of the University of Macau. “War strengthens individuals’ religiousness (due to) their worries about war, while fundamental religious beliefs result in violent conflicts and war.”
