Theism Bias and Atheism Bias

It's possible to have a cognitive bias in favor of theism, as well as one in favor of atheism, or opposed to theism.

One experience that I had that makes me think that atheism bias may be a thing is what happens sometimes when I think about credences for the existence of God. I have found, often enough, that I can't believe in God unless I arrive at some internal credence of 1 that he exists. I think when we believe things to be true, it is often to us as though there is no possibility of them being false. To be made aware of uncertainty somehow completely destroys a belief.

A credence of 0.9 isn't good enough for me. I can't seem to process the probability of God existing, which ought to go a long way even if certainty isn't possible. Humans might not ought to be expected to be good at thinking involving probability, but I think there's even an inconsistency in me there, where the 90% threat of something means something to me, but threats that are 90% likely given the 90% likelihood that God exists do not bother me as much as they should, while I do respond (with fairly assiduous avoidance) to most 90% chances of threats that I think matter. I do think that unwittingly being deceived by Satan matters (a likely risk given the 90% chance the worldview obtains which includes the God I believe in). But I seem to often not naturally care about it for some reason, and I suspect that there is some kind of atheism bias at play. Rationally, I should care (at least by my lights), but sometimes find that I don't.

(Another explanation, which may avoid bringing in the concept of atheism bias: this may be a case where my belief in Satan has been more often in the past an ought-belief rather than an is-belief. On the other hand, maybe atheism bias often just is the difficulty of is-believing things related to God.)

That's an atheism bias that cuts through my usual theism bias. Atheism biases can find a more welcome home in other people (maybe the welcome home for them can itself be a bias).

Theism bias and atheism bias both (at least partially) discredit theistic and atheistic beliefs formed under their influences. It's possible that atheistic beliefs that break through a theism bias, or theistic beliefs that break through an atheism bias, are to be given more credit, for having arisen under hostile circumstances. However, I think that if you want to believe something badly enough, it generates its own bias both toward and away from belief. In other words, the fact that theism bias discredits beliefs formed under its influence creates an automatic atheism bias, which then discredits atheistic beliefs as well. (This puts a person in a kind of impossible position, at least while it lasts.) If atheists want to be atheists badly enough, the same dynamic should hold for them.
