Argue that we can have zero or virtually zero credence in total views
FWIW, I’ve comprehensively done this in my moral anti-realism sequence. In the post Moral Realism and Moral Uncertainty Are in Tension, I argue that you cannot be morally uncertain and a confident moral realist. Then, in The “Moral Uncertainty” Rabbit Hole, Fully Excavated, I explain how moral uncertainty works if it comes with metaethical uncertainty and I discuss wagers in favor of moral realism and conditions where they work and where they fail. (I posted the latter post on April 1st thinking people would find it a welcome distraction to read something serious next to all the silly posts, but it got hardly any views, sadly.) The post ends with a list of pros and cons for “good vs. bad reasons for deferring to (more) moral reflection.” I’ll link to that section here because it summarizes under which circumstances you can place zero or virtually zero credence in some view that other sophisticated reasoners consider appealing.
