Sceptical scenarios and Quantum Mechanics
It's occurred to me that on most non-Bohmian interpretations of quantum mechanics, we end up being in a superposition of the kind of universe we think we're in and a sceptical scenario, e.g., some brain in a vat scenario, though details of the scenario may differ depending on an interpretation. All that's needed for that to happen is for there to have been a non-zero chance of a sceptical scenario with the same phenomenal states that we actually have. I don't know if this is a problem if the sceptical scenario is assigned low weight by the wavefunction.
