1) Most people appear to have avoided thinking critically about any of their beliefs at all. At best they are repeating poorly-understood arguments from other people they respect, at worst they are playing team sports.

This is usually given as a reason for people being dumb, not thoughtful, etc. But I think it’s more of a misreading of what these belief systems (itself a misleading name) are actually doing.

The belief aspect is interpreted by intellectual, argumentative types as the key lynchpin, whereas the actual “believer” (again, loaded language here presuming that belief is central) is a member of the community because it provides social benefits, a sense of meaning in a confusing universe, a connection to their personal ancestry and culture, and so on. The actual belief itself isn’t unimportant, but it’s not the reason why the person is there in the first place.

This is why the approach of atheists critiquing some specific belief of X religion or Y holy book never convinces the religious practitioner (a better word than believer, IMO) of anything. Adopting a belief didn’t get them into the community and critiquing that belief won’t get them out.

As the cybernetic phrase goes, “a system is what it does.” Not what it claims to be doing, or is described as doing by a particular class of people. And that is why skepticism often doesn’t really go anywhere – it’s focusing on the belief and ignoring the vast anthropological and sociological aspects under the surface.
