 There is also the potential problem of new, previously unconsidered hypotheses all lumped together in the catch-all basket. Without knowing the details of what specific unconsidered hypotheses might look like, there is simply no plausible way to anticipate the apparent likelihood of a novel new hypothesis—let alone its other potential explanatory virtues. This, on some views, is essentially what happened with traditional design arguments—such arguments were the most reasonable available until Darwinian evolution provided a plausible (or better) alternative the details and likelihood of which were not previously anticipatable.
