What Religion is For
Religion consumes up to a tenth of economic productivity in some societies. So it must produce corresponding benefits. What are they? By religion, I mean any supernatural belief system that is invoked with the intention of altering the outcomes of an individual, or group. Clearly, there are many different types of religion ranging from the animism practiced in small-scale hunter-gatherer societies to the more grandiose efforts carried on in Egypt at the time of construction of the Great Pyramids.
