I suspect Vasco is reasoning about the implications of epistemic principles (applied to our evidence) in a way I’d find uncompelling even if I endorsed precise Bayesianism.
Oh so for the sake of argument, assume the implications he sees are compelling. You are unsure about whether your good epistemic principles E imply (a) or (b).[1]
So then, the difference between (a) and (b) is purely empirical, and MNB does not allow me to compare (a) and (b), right? This is what I’d find a bit arbitrary, at first glance. The isolated fact that the difference between (a) and (b) is technically empirical and not normative doesn’t feel like a good reason to say that your “bracket in consequentialist bracketing” move is ok but not the “bracket in ex post neartermism” move (with my generous assumptions in favor of ex post neartermism).
I don’t mean to argue that this is a reasonable assumption. It’s just a useful one for me to understand what moves MNB does and does not allow. If you find this assumption hard to make, imagine that you learn that we likely are in simulation that is gonna shut down in 100 years and that the simulators aren’t watching us (so we don’t impact them).

Gotcha, thanks! Yeah, I think it’s fair to be somewhat suspicious of giving special status to “normative views”. I’m still sympathetic to doing so for the reasons I mention in the post (here). But it would be great to dig into this more.
