Yeah. Steve. Lisa, I agree that are religious belief can reduce stress but I don't think that that can be an explanation as to why it's adaptive. Because the fact that uncertainty leads to stress is itself an adaptation, namely there ... we're missing some information that's critical to our well-being and we're ... when we get stressed and nervous that motivates us to seek out that information or to act in a way that keeps us safe even in the state of ignorance. But there can't be an adaptation to reduce stress by false certainty.
