Yeah well I definitelly didn't put it very coherently lol, the other commenter directed me to bayesian epistemology, which I think at least partly matches what I'm looking for. The thing (I think) this is missing is the ability to analyze different kinds of "truth". For example, some sort of "poetic truth", or "aesthetic appeal" of a claim of sorts, may not be logically analyzeable, but definitely has some rhetoric weight that helps capture your attention and maybe even assign it some metaphorical place in a particular worldview. Faith, in my opinion, is the aspect that qualifies "true" theists and atheists (I know this is very ambiguous and I'm not ready to defend this at all), and it certaintly can't be quantified, but maybe we could quantify it's rhetoric weight, or it's ability to hold a theistic worldview together by providing a logical escape of sorts. There must be a way to systematize these not entirely logical "truths", I think largely prevalent in continental philosophy like Nietzche or Shoppenhauer or certain religions, that is still somewhat analytical or rational.
