  According to one suggestion along those lines, what moral disagreements reveal is that the abilities or methods we use to form our moral beliefs are not sufficiently reliable or truth-tracking. They may fail to be so, for example, by being such that, even if the beliefs we have formed by using those methods are in fact true, we could easily have ended up with false ones. If we could not easily have been mistaken (by using the same methods that we used to form our actual beliefs), then our beliefs are sometimes said to be “safe”. Some theorists take safety to be a necessary condition of knowledge (see, e.g., Pritchard 2005 and Williamson 2000). If it could be shown that existing moral disagreements indicate that our moral beliefs are not safe, then this offers a way forward for moral skeptics (for this idea, see e.g., Mogensen 2016; Hirvela 2017; Risberg and Tersman 2019; and Clarke-Doane 2020, 148).
