As I said in responding to another comment, this is the part of UU that I relate to. However, the problem is that while UUs might be slightly above average rationality, "we can use reason when we can" means that beliefs come from thinking for yourself as opposed to reading e.g. the bible, and the stuff they come up with by thinking for themselves is usually not all that great by my standards. I am worried that I am giving UU too much credit because they happen to use the word "reason," when in reality they mean something very different than what I mean.

They are just humans, aren't they? I am afraid that at this moment it is impossible to assemble a large group of people who would all think on LW-level. Not including obvious bullshit, or at least not making it a core of group beliefs, is already a pretty decent result for a large group of humans.
Perhaps one day CFAR will make a curricullum that can replicate rationality quickly (at least on suitable individuals) and then we can try to expand rationality ...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
