Second Thoughts About My Favourite Theory

Abstract

: A straightforward way to handle moral uncertainty is simply to follow the moral theory in which you have most credence. This approach is known as My Favourite Theory. In this paper, I argue that, in some cases, My Favourite Theory prescribes choices that are, sequentially, worse in expected moral value than the opposite choices according to each moral theory you have any credence in. In addition, this problem generalizes to other approaches that avoid intertheoretic comparisons of value, such as My Favourite Option, the Borda Rule, Variance Normalization and the Principle of Maximizing Expected Normalized Moral Value.
