Do you think the available evidence, overall, is so finely balanced that somewhere between 5% and 95% confidence (say) is appropriate? That would be fairly surprising given how much evidence there is out there that's somewhat relevant to the question of gods. Or do you think that, even in the absence of dramatic epiphanies of one's own, we should all be way more than 95% confident of (something kinda like) theism? I think I understand your statement about social epistemic rationality but it seems to me that a better response to the situation where you think there are many many bits of evidence for one position but lots of people hold a contrary one is to estimate your probabilities in the usual way but be aware that this is an area in which either you or many others have gone badly wrong, and therefore be especially watchful for errors in your thinking, surprising new evidence, etc.
