I’ve noticed that religious guys in prison are kind of like religious guys everywhere: they’re out-and-out victims of the confirmation bias. That is, they find a belief that seems to work for them, and run with it. No attempt is made to look at this belief critically. If they do any real studying on the belief, it’s always in support of it.
This is bad, whether the belief is religious or not. It turns off our critical thinking mechanism, and that is what prisoners need the most. Not faith, but rational thinking. And I’ve said it before, once you can think critically about God, it becomes a lot easier to do so about everything else in your life, particularly your behavior and decisions.
