Which implied prior? My understanding is that the problem with Multiverse theories is that we don't have a way to assign probability measures to the different possible universes, and therefore we cannot formulate an unambiguous prior distribution.
Well, I don't really math; but the way I understand it, computable universe theory suggests Solomonoff's Universal prior, while the ZFC-based mathematical universe theory--being a superset of the computable--suggests a larger prior; thus weirder anthropic expectations. Unless you need to be computable to be a conscious observer, in which case we're back to SI.
