Director of Operations at GovAI. I have a blog about nonprofit ops and strategy.
I previously co-founded and served as Executive Director at Wild Animal Initiative, was the COO of Rethink Priorities from 2020 to 2024, and ran an operations consultancy, Good Structures, from 2024-2025.
Math nitpicks are helpful, thanks! Both were right—just doing math too quickly :).
RE welfare comparisons: I could imagine a difference between us being relative confidence that empirical research will improve our understanding? I think I might be less bullish on this sort of work because I don’t feel confident we’ll meaningfully reduce our uncertainty about welfare ranges. But, I’m not confident in this. Would you expect the most useful work for reducing your own uncertainty to be philosophical or empirical?
RE nematodes: I agree that this isn’t clear cut in some sense, but I feel fairly confident that they should be bracketed out unless we significantly advance in our understanding of animal consciousness (and see above—maybe my own lack of confidence in our ability to make empirical progress on this is part of the reason I’m more confident in casting them aside).
RE cage-free: yes — I think the meaningful counterfactual is that money spent on cage free otherwise not being spent on animal welfare at all, or being spent in mostly useless ways, and I’d endorse cage-free campaigns over that most likely, despite agreeing with you on non-target uncertainty being high, but I haven’t thought about it much.
