But then again I’m worried that once we allow for all these conceivable events that we can’t figure out much about to have positive probability, we’re opening the floodgates for an ever-more-extreme apportionment of resources to lower-and-lower probability catastrophes.
Right, but then that seems like a different objection, e.g., a recluctance to taking Pascal’s wager-type deals, or some preference related to your risk averseness, or some objection to expected value calculations under not-particularly-resilient low probabilities. But then that feels more like the true objection, not the computational complexity part. Would you say that’s a fair characterization?
I do think that the issues with Pascal’s wager-type deals are compounded by the possibility that the positive probability you assign to the relevant outcome might be inconsistent with other beliefs you have, and settling the question of consistency is computationally intractable). In the classic Pascal’s wager, there’s no worry about internal inconsistency in your credences.
