Hi Jeff. Thanks for engaging. Three quick notes. (Edit: I see that Peter has made the first already.)
First, and less importantly, our numbers don’t represent the relative value of individuals, but instead the relative possible intensities of valenced states at a single time. If you want the whole animal’s capacity for welfare, you have to adjust for lifespan. When you do that, you’ll end up with lower numbers for animals—though, of course, not OOMs lower.
Second, I should say that, as people who work on animals go, I’m fairly sympathetic to views that most would regard as animal-unfriendly. I wrote a book criticizing arguments for veganism. I’ve got another forthcoming that defends hierarchicalism. I’ve argued for hybrid views in ethics, where different rules apply to humans and animals. Etc. Still, I think that conditional on hedonism it’s hard to get MWs for animals that are super low. It’s easier, though still not easy, on other views of welfare. But if you think that welfare is all that matters, you’re probably going to get pretty animal-friendly numbers. You have to invoke other kinds of reasons to really change the calculus (partiality, rights, whatever).
Third, I’ve been trying to figure out what it would look like to generate MWs for animals that don’t assume welfarism (i.e., the view that welfare is all that matters morally). But then you end up with all the familiar problems of moral uncertainty. I wish I knew how to navigate those, but I don’t. However, I also think it’s sufficiently important to be transparent about human/animal tradeoffs that I should keep trying. So, I’m going to keep mulling it over.
