Looking it the first link https://www.lesswrong.com/w/epistemology - it has frankly a comically shallow description of the topic, same with https://www.lesswrong.com/w/priors. In just about every discussion, I may be just the entirely wrong audience, but to me they don't even begin to address the narrow topic of choice, let alone form competent building blocks to form any solid world view.

I support anyone trying to form rational pictures of the universe and humanity. If the LessWrong community approach seems to make sense and is enriching to your understanding of the world then I am happy for you. But, every time I try to take a serious delve into LessWrong, and I have done it multiple times over the years, it sets off my cult/scam alerts.
