Moral uncertainty (or normative uncertainty) is uncertainty about howwhat we ought, morally, to actdo given the diversity of moral doctrines. For example, suppose that we knew for certain that new technology would enable more humans to live on another planet with slightly less well-being than on Earth1. An average utilitarian would consider these consequences bad, while a total utilitarian would endorse such technology. If we are uncertain about which of these two theories are right, what should we do?

Even with a high degree of moral uncertainty and a wide range of possible moral theories, there are still certain actions that seem highly valuable in any theory. Bostrom argues that Existential risk reduction is among them, showing that it is not only the most important task given most versions of consequentialism,consequentialism but highly recommended by many of the other widely acceptable moral theories3.
