I've been thinking about it for a while and I just can't crack it. Plenty of non-religious people in my friend and acquaintance circle believe that after they die their souls will leave this world and... well they won't actually die, I guess.
I just don't see the social value in that. The subject comes up so rarely that it doesn't really matter. If I had to guess how it works, it looks more like some sort of self-defense mechanism than anything - avoiding thinking about (potentially) depressing things that aren't actionable.
So I guess my problem is that I can't find a way to fit that in the proposed framework, unless I missed something?
_edit_
If my assumption about how it works is correct (self-defense) than it would have near 0 social value, but a lot of practical value (not worrying about things beyond one's control). Yet it still sounds like a crony belief - it's most likely not how the universe works imo.
