 SR can be defended as a rational ideal by Dutch Strategy arguments, though not by the strongest kind of Dutch Book argument (Sobel 1987; Christensen 1991, 2007b: 328–330, 2010b; Briggs 2010—Roush 2016 argues it can’t be defended as a requirement by a Dutch book argument at all). It has been argued to be questionable if not false on grounds that it conflicts with the Epistemic Impartiality Principle that says we should not in general take the mere fact that we have a belief as a reason to have that belief any more so than we do with the mere fact that others have that belief (Christensen 2000: 363–4; Evnine 2008: 139–143; Roush  2016).[1]
