The point about the optimal prior was that, to the extent that a prior can be considered biased (in the sense I understood the word “bias”, not inductive bias), the optimal prior is the unbiased prior it should be compared to. I didn’t mean to imply that finding the optimal prior is realistic.
OK, that clears it up then.
