I thought about the "No True Scotsman" fallacy, but I would imagine that if we establish the definition of atheism as "lack of belief in god(s)," then we can actually assign people a Yes or No to the question of atheism. Particular religious sects are a bit slipperier, because of the litany of beliefs and variations thereof that apply.

Is there any evidence that faith-based programs improve prison conditions or reduce recidivism rates?
