Note that LHC failures would never count as evidence that the LHC would destroy the world. Given such weird observations, you would eventually need to consider the possibility of an anthropic angel. This is not the same as anthropic shadow; it is essentially the opposite. The LHC failures and your theory about black holes implies that the universe works to prevent catastrophes, so you don’t need to worry about it.
Or if you rule out anthropic angels apriori, you just never update; see this section. (Bayesianists should avoid completely ruling out logically possible hypotheses though.)
