I agree people hold foundational beliefs, but they don’t seem to be things like materialism which then impose some logical consequences.

Instead it’s stuff like the fundamental nature of specific organizations/ideas. You can far more easily find an agnostic Catholic than one who believes the Catholic Church is irredeemably evil.

I’d call it tribalism rather than herd behavior because animal herds don’t attack other herds. Meanwhile football fans will fight each other over effectively arbitrary teams.

I don't think one's opinion on the Catholic Church could be said to be "foundational"–for the vast majority of people.

If someone dislikes or disagrees with Catholicism, likely that is because of some other belief against which they are judging Catholicism – and that belief is more fundamental to them than any of their beliefs about Catholicism.

An atheist disagrees with all religions, Catholicism included – but their atheism (and related views such as anti-supernaturalism and physicalism) is far more foundational than their views on Catholicism specifically, which is just the application of their general principles to one of many specific cases.

A follower of a competing religious tradition – Jewish, Hindu, Muslim, Protestant, etc – disagrees with Catholicism whenever it contradicts the teachings of their own religion. But, once again, their belief in their own religious tradition is more foundational to them than their rejection of Catholicism whenever it contradicts it.

A social progressive disagrees with Catholicism's teachings on abortion, LGBT issues, the role of women, etc – their beliefs on those topics may well be foundational, but their judgement of Catholicism is not foundational, it is just an application of those (more) foundational beliefs.

I think the only people for whom their views on Catholicism would be foundational, would be some devout Catholics. But, even among devout Catholics, I'm not sure if all of them would label their belief in Catholicism as foundational. Some might. Others might argue for Catholicism on the basis of philosophical and historical arguments, in which case those arguments (and the principles which underly them) might be said to be more foundational for them than Catholicism itself is.

I’m not saying these specific beliefs are foundational for everyone that holds them or even that those people would label them as foundational, just that they preform that function for some people. Being American is a huge part of some peoples identity and largely irrelevant to others.

It could their job, politics, culture, hobby, or even taste in music etc. But many people seem to crystalize around some external concept. It’s not as clear as I’m a “vegan” or “Republican” therefore I believe all these things, but identifying as something seems to have knock on effects. Someone thinks of themselves as having made it into an higher economic status and suddenly they have options about wrist watches or whatever. People will not just own a PlayStation/BMW/whatever but reject competing brands and think this then implies other things about themselves.

Maybe we are using "foundational" somewhat differently?

You start talking about "foundational beliefs", and I immediately think https://en.wikipedia.org/wiki/Foundationalism – maybe that's a consequence of having studied philosophy at university

I doubt many people derive their beliefs from a hobby or taste in music. You can find people who share the same hobby or like the same music, even while their views on politics / religion / social issues / etc are at complete opposite ends of the spectrum.

Foundationalusm assumes an internal logic to people’s belief systems that simply doesn’t hold up in practice.

People don’t decide the big questions to build up a belief system from the ground up. Instead they work from the middle of a web of beliefs. Arguably the true foundations of belief are things like object permanence which we discover as infants. Ie: Closing my eyes doesn’t make something go away.

Older kids ask questions like “what’s the point of life?” and get culturally appropriate responses from parents, religious leaders, TV or whatever. They don’t ask about things like materialisms vs dualisms vs idealisms until they are even older and have built up a complex web of interlocking beliefs.

Sure, few people will hear about “materialism” or “dualism” or “idealism” as philosophical theories until adulthood, if that. But that doesn’t mean they aren’t presumed by a lot of things ordinary people say, and which children and adolescents end up hearing.

Someone who says “there is no afterlife: there is no scientific evidence for it” is effectively presuming materialism, even if they don’t know what “materialism” is. (Many people only know “materialism” as “excessive emphasis on material goods”, not the philosophy of mind sense.)

I agree, my point is that predisposition.

Though I can’t help but adding… You can have a non material world without having an afterlife (telekinesis or spells working) and you can have an afterlife in a material world (via active intervention and time travel).

So rather than materialism being foundational it can be thought of as a category that arises from more foundational beliefs.
