I think there is a measurable, categorical difference in the degree of self-awareness and self-delusion, though. Certainly not in every case, on either side, but I’d be willing to bet that a careful and objective study of the subject would (and probably has to all the people who are much better educated on the subject than me) yield results that are far less surprising to many non-believers than believers, but that just gets us right back to how difficult it is to admit or even recognize when we’re wrong. And we’re all wrong about something, many things, much of the time, often without any awareness of it. Unless and until we’re doing actual arithmetic, thinking logically is just not in our nature as sentient, creative, developing apes. Metacognition to the degree of which we’re apparently uniquely capable may separate us from other animal life in seemingly important ways, but it’s not nearly as well-developed as we (all) like to Believe™ it is. Just my point of view as someone suffering from that same universal condition.

I absolutely agree. The problem is when they are coming from a place of righteousness that it makes it too spicy for even the most seasoned entrails. Us spiritual hillbilly types know we’re the human equivalent of garbage water so we usually don’t go around telling others how to live their lives.

Humans have the tendency to be sure, but some people deplore hypocrisy while others do not.
