Moral uncertainty: how to act when you’re uncertain about what’s good

Abstract

We can be uncertain about matters of fact, like whether it’ll rain tomorrow, but we can also be uncertain about moral claims, like how much to value the interests of future generations. In the last decade, there has been more study of how to act when uncertain about what’s of value, and our cofounder, Will MacAskill, has written a book on the topic. An approach that’s common is to pick the view that seems most plausible to you, and to go with that. This has been called the ‘my favourite theory’ approach.
