I work as an engineer, donate 10% of my income, and occasionally enjoy doing independent research. I'm most interested in farmed animal welfare and the nitty-gritty details of global health and development work. In 2022, I was a co-winner of the GiveWell Change Our Mind Contest.
Thanks Vasco!
I checked the pages for each charity to get the scores.
I agree that AWF doesn't directly evaluate cost-effectiveness, but I still think there's a good chance they're likely to be the EV maximizing option over THL. THL estimates that it costs them $2.63 to move a hen from a conventional to a cage-free system, or about 0.57 yr/$ given a 1.5-year lifespan. Last year, Emily Oehlsen from Open Phil said "We think that the marginal [farmed animal welfare] funding opportunity is ~1/5th as cost-effective as the average from Saulius’ analysis." Saulius's 2019 analysis estimated that corporate campaigns pre-2019 impacted 41 chicken-years per dollar, so at a 5x reduction that's 8.2 yr/$. I don't want to take Emily's numbers too literally, but that implies a >10x gap between the cost effectiveness values of OP's marginal funding opportunity and THL. Since I'd expect AWF's opportunities to look somewhat similar to OP's, that leads me to guess that they're likely to be on net more cost-effective than THL. This directionally agrees with some of the comments by insiders such as @James Özden on the GWWC evaluations thread as well. But I'd be very curious to hear more from folks who are more plugged in, this is just an outsider's guess.
For what it's worth, I do actually give to both AWF and THL, but give much more to AWF.
A couple things to add to this very good comment:
In general, the landscape of charity evaluation for animal charities is less mature and quite a bit more uncertain than the landscape for global health and development charities. Any cost-effectiveness estimates are going to be coarse and debatable.
ACE has a partially qualitative cost-effectiveness scoring system. Their ratings (higher = better) for their recommended charities are:
@Laura Duffy wrote a report at Rethink Priorities in which she estimated that corporate hen welfare campaigns avert 1.13 DALYs/$ and shrimp stunning interventions avert 0.038 DAYLYs/$. Both of these estimates were quite uncertain and depended on a lot of debatable assumptions (including possibly underrating the potential for shrimp stunning interventions to catalyze industry-wide changes), but I think this is one of the best estimates currently out there.
My personal advice would be that I think the EA Funds Animal Welfare Fund is probably the expected value maximizing option, while The Humane League is probably the best option if you're somewhat risk-averse.

Thanks so much for your response, that all makes sense!
You're understanding question 3 correctly - GiveWell's moral weights look like the following, which is fairly different from valuing every year of life equally.
Thanks so much for going on the podcast and for the incredible work that you and everyone involved in r.i.c.e. are doing! It's amazing that you've been able to save so many lives so cost-effectively. I did have a few questions I was curious about though:
Yeah this is a really good point, I have no idea how to square the numbers with big grants from OP to THL
