Cromwell’s rule: you prior probability can never be zero about anything, otherwise it would stay zero in the face of any evidence.
The flip side is that some actually useful hypotheses are inaccessible on a fundamental level, so you can’t ever be a True Bayesian. Sorry. This might map to epistemic humility.
