“Suppose we’re 90% confident that all generations have equal moral value, and believe there’s a 10% chance that only the current generation matters. (There are other possibilities but let’s narrow it down to these two for simplicity’s sake.) There’s no agreed-upon method for handling this kind of moral uncertainty, but let’s say we handle it by assigning resources to each moral system in proportion to our confidence in it and then let each system “buy” what it wants. So if we have $1 million, we give $900,000 to our first moral system which says that all generations have equal moral value, and $100,000 to our second system which only values the current generation. Then each system can use the money on whatever intervention it believes is best, or they can trade with each other.”
