What’s a view you hold most EA-minded animal advocates would disagree with?
What’s a view you hold most EA-minded animal advocates would disagree with?
My views are pretty aligned with most EA-minded animal advocates. But in the interests of finding disagreement, here are a few possibilities:
Sorry to not be more disagreeable ;)
Are the things in the bullets the things you believe or the things you disagree with?
Things I believe. Though I'm really torn on the Huel vs. Soylent one
If you had to place the different kinds of work within farmed animal welfare (e.g. corporate pressure campaigns, alternative proteins, persuading people to be vegan, etc) into different tiers based on how optimistic you are about them (e.g. 'very optimistic', 'moderately optimistic', etc) what would they look like?
Fun question! Here’s a rough hierarchy, with my most optimistic up top. Note that these are averages globally, and some approaches might be much more promising in certain countries, or when done by certain groups.
Corporate animal welfare campaigns
Alternative proteins
Farm animal welfare technologies and innovations
Movement-building in LMICs
Legislative animal welfare advocacy
Movement-building in rich countries
Institutional meat reduction
Litigation for farmed animals
Persuading people to be vegan
Holistic food systems reform
Farm transitions
Of course there are lots of other interventions being tried! Let me know if you want my thoughts on any others.
Many grantee organisations report the lessons they learnt to their donors. Open Philanthropy must have accumulated a lot of information on the best practices for animal welfare organisations. As far as I understand, grant makers are wary of giving object level advice and micromanaging grantees. On the other hand, many organisations already spend a lot of time trying to learn about the best (and worst) practices in other organisations. Could Open Phil animal welfare team prepare an anonymised write up about what their grantees report as the reasons for their successes and failures?
This is a cool idea! As you note, we’re wary of telling grantees how to run their organizations. We’ve generally preferred to fund groups that can work with grantees to help them implement best practices that work for them. For example, Scarlet Spark, Mission Realization Partners, and (previously) Sharpen Strategy. But we’ll think about whether we could prepare an anonymized write up like you suggest.
Thanks for the announcement, Toby! Thanks for doing an AMA, Lewis!
What are your best guesses for the mean, and 5th and 95th percentiles of the marginal cost-effectiveness of Open Philanthropy's (OP's) animal welfare grants in DALY/$? For reference:
If there were 1 blog article on animal welfare that you would want everyone to read so that we were all up to speed on the topic, what would it be?
I’m not sure there’s one neat article. I’d love someone to write such an overview. In the meantime, your best bet might be Our World in Data’s cool new section on animal welfare. For a wrap up on progress over the last decade, you could also read my 2022 year-end newsletter.
Do you think there are promising ways to slow down growth in aquaculture?
No. I think it’s near impossible to slow the growth of a major industry like aquaculture. You could slow its growth in particular countries but, so long as demand remains constant, production will just expand elsewhere. That’s especially true given the vast majority of aquaculture is in countries where we have no hope of slowing its growth.
You could try to reduce demand for farmed fish, but we’ve never succeeded in reducing demand for such a popular food in the past. (And even if you did, people would probably just switch to wild-caught fish. This might just boost demand for farmed fish, since wild-caught fish are supply constrained, and most people view wild-caught and farmed fish as interchangeable, so most marginal fish demand is satisfied with farmed fish.)
The year is 2100 and factory farming either does not exist anymore or is extremely rare. What happened?
Alien invasion.
What percent of farmed animal welfare advocacy does Open Phil fund? How valuable would it be for the cause area to have additional major funders?
We’re about a quarter of global farmed animal welfare advocacy spend, based on a broad definition of such advocacy, i.e. including alt protein work, vegan advocacy, etc. We’re a larger share of what I’d consider evidence-based or EA-aligned advocacy. Depending on what you include in that category, we’re about half to two thirds of funding for such work.
It would be very valuable to have additional major funders! For example, I’m excited to see the Navigation Fund coming online shortly. In addition to enlarging the pie of total farmed animal welfare funding, new funders could add a greater diversity of perspectives and provide more stability for groups. (We’ve seen that groups majority funded by us are often wary of investing in long term growth because they’re nervous about being so reliant on one funder.)
I spend a chunk of my time trying to bring new major funders into the space. We’re also funding work with Farmed Animal Funders and Focus Philanthropy toward the same goal. I welcome ideas on how we could do better at this!
What's going on with the progress on breeds for the Better Chicken Commitment? I've heard it hasn't been going well. But I think I also read the BCC hadn't actually settled on breeds until after many commitments were made, so we wouldn't expect them to start making progress on breeds until after that, anyway. But I think we have settled on approved breeds for a while now.
Yeah both statements are true. The US Better Chicken Commitment lacked a list of approved breeds for many years due to delays at the Global Animal Partnership, which was in turned delayed by a study on breed welfare outcomes at the University of Guelph. My understanding is that a lot of those delays were due to attempts by the Guelph researchers to address concerns from the breeding companies about how to ensure the fairness of the study's methodology. Of course the breeding companies dismissed the study's results -- finding welfare problems wit their fastest growing breeds -- anyway.
My understanding is that most US companies with BCC pledges are yet to make any progress on adopting higher welfare breeds in their supply chains. I suspect that's mostly because it's the most expensive change in the BCC, since higher welfare breeds grow slower and have a worse feed conversion ratio. But it doesn't help that most major US chicken producers have refused to even meet their corporate customers' requests to raise higher welfare breeds.
As usual, things are going better in Europe. The Danish and Dutch retail sectors now sell almost entirely chicken from higher-welfare breeds, while I think French retailers are making solid progress. Still, there's a lot more work to do!
From ChickenWatch’s Commitment Tracker, it seems like there's a decrease in the number of BCC and in total commitments
| Year | Better Chicken commitment | Total commitments |
| 2023 | 11 | 149 |
| 2022 | 19 | 253 |
| 2021 | 35 | 329 |
| 2020 | 60 | 364 |
| 2019 | 53 | 494 |
| 2018 | 26 | 480 |
| 2017 | 77 | 389 |
(I simply counted descriptions that included "Better Chicken" as a substring, and haven't double-checked for errors)
[It doesn't necessarily mean that things are getting worse. ChickenWatch could be missing more stuff, maybe larger commitments are bundled together, commitments could generally be getting larger in their ask or the target corporate, etc.]
Looking at major changes societies have adopted in the past, the path to these changes has often been nonlinear. A frequently-discussed example is the U.S. civil rights movement, where the extent of violent opposition reached a near zenith just before the movement's largest victories in the 1950s and 60s. Gay marriage in the U.S. was another example: in a 15-year period ending three years before marriage equality was decided by SCOTUS, advocates watched a wave of anti-gay marriage state constitutional amendments succeed at the ballot 30-1. Women's suffrage, the New Deal, and (most extremely) the abolition of slavery were all immediately preceded by enormous levels of opposition and social strife.
How, if at all, does OP account for the frequent nonlinearity of major societal changes when deciding what interventions to support on behalf of farmed animals?
Thanks Aidan. I agree that much social change is nonlinear and hard to predict. I also agree that violent opposition preceded some significant social changes, though I'm more inclined to see that as a symptom of the issue having achieved high social salience rather than as a cause of the change.
I studied historic social movements in college and it's been my hobby since, and it's left me wary of extracting general lessons from past movements, since I think they often fit our prior beliefs. For instance, I see in the US civil rights movement a movement that for decades clocked up small achievable incremental legal and political wins in service of several larger incremental wins (two key federal laws and several Supreme Court rulings) but that failed in its more radical goals (racial and economic equality). I see in gay marriage a movement that largely sidelined radical calls to end marriage and other oppressive institutions in favor of a disciplined focus on a quite narrow practical goal: marriage equality. And I see the US abolitionists' radical goals and tactics as largely a failure alongside the UK abolitionists' more moderate ones, which achieved abolition decades earlier and without a war. But I suspect this is largely me projecting my beliefs on the past.
We're supporting a lot of work that relies on nonlinear theories of change, for instance our work to build a field of farm animal advocacy across Asia, to build a field of fish welfare advocacy and research, and to promote hard-to-predict alt protein R&D. I'm not confident though that that work will have better secondary effects on social change than our linear work. For example, I've seen cage-free campaigns build public momentum, activist morale, and support for political reforms. But I agree it's likely we're missing important work to seed future nonlinear reforms. I just find it hard to work out what that work is.
Interesting question, Aidan! Relatedly, I liked 80,000 Hours' podcast Cass Sunstein on how social change happens, and why it’s so often abrupt & unpredictable. One of the topics they discuss is whether the way the world treats farmed animals could abruptly change.
What are your thoughts on replicating the success of prop 12/question 3 in new states as well as campaigning for new initiatives in Massachusetts and California (e.g. chick culling ban)? Is anyone working on this?
I’m not aware of anyone currently working on this. The immediate priority is to stop Congress from preempting Prop 12 / Question 3 and other laws like them. House Republicans have put text in their version of the Farm Bill to do so, so there will be a major fight on this in the coming months.
If we survive that fight, I’d like to see more ballot measures with popular farm animal welfare reforms. There are a few constraints to be aware of:
An initiative needs to be simple enough to attract votes (confused voters vote no), but complex enough to address the biggest animal welfare challenges (e.g. try defining higher welfare broiler breeds in a way the average voter will endorse).
Do you think broiler breed ballot initiatives are worth trying or at least investigating further, given the potential upside and cost-effectiveness of cage-free ballot initiatives (Duffy, 2023)? EDIT: Also see Khimasia, 2023 on potential broiler ballot initiatives, from CE/AIM's research program.
Have there been surveys/polls on potential broiler initiatives (target states, wording, etc.)?
They seem quite promising to me, but the first step should be further investigation, e.g. finding the best wording for expected impact (impact if passed x probability of passing).
If I donate 1 k$ to an organisation which is significantly funded by Open Philanthropy, how much less money in expectaction will Open Philanthropy grant to that organisation? I think corporate campaigns for chicken welfare are super cost-effective, so I am tempted to donate to The Humane League (THL). According to Animal Charity Evaluators, they have a funding gap of 10.5 M$ for 2024 to 2025. However, as I commented elsewhere:
Open Philanthropy (OP), which granted 8.3 M$ to THL in 2023, presumably wants to fund THL up to a certain point. Other donors donating to THL could simply mean OP has to donate less. So I wonder whether donating to THL has the same effect as donating to OP. If this is so, donating to THL would be equivalent to mostly supporting human welfare interventions. Based on OP's grants data on 17 February 2024, only 9.98 % of the money granted by OP has gone to animal welfare interventions.
I guess donations to AWF [Animal Welfare Fund] do not suffer as much from the above.
I would also be curious about your thoughts on the sentence just above.
There are two separate funging worries here. First, will donating more to THL mean that OP gives less to THL? Answer: probably not, for a few reasons. (1) One factor limiting our funding for THL and other groups is how much of their budget we're both comfortable with OP being. So donating to them could actually increase our giving by lowering our portion (though see next point that any additional funds will come from elsewhere within the farm animal welfare budget). (2) Room for more funding / neglect is only one consideration in our grant sizing for groups, including THL, and (3) Our grant sizing for big grantees like THL is quite coarse: we only consider it once every three years and are unlikely to be swayed by small fluctuations in their funding.
Second, will donating to THL mean that OP gives less to farm animal welfare? Answer: almost certainly not. OP’s farm animal welfare team has a set budget, so even in the unlikely event we funged your gift to THL, our funds would go to other animal groups instead. In theory, new outside funding could lead OP to view farm animal welfare as less neglected, affecting our budget, but I don't think perceived lack of neglect is a limiting factor on our budget. (And I don't think it would become one until funding increased by a huge amount, e.g. >$50-100M.)
Fwiw, I still personally donate to THL (and other groups).
Thanks, Lewis!
(1) One factor limiting our funding for THL and other groups is how much of their budget we're both comfortable with OP being.
How often is this the limiting factor? If quite often, then I agree funging would be small.
(2) Room for more funding / neglect is only one consideration in our grant sizing for groups, including THL
I think my point holds as long as all the considerations boil down to you setting a given target funding in $.
(3) Our grant sizing for big grantees like THL is quite coarse: we only consider it once every three years and are unlikely to be swayed by small fluctuations in their funding.
In general, I do not think the consideration above matters much. The situation seems analogous to one eating 100 g less chicken leading in expectation to a decrease in chicken production by something close to 100 g (a little lower because the elasticity is lower than 1), despite the very low probability of eating less 100 g of chicken affecting the number of batches of chicken (which I guess respect at least tens of kg). Likewise for funding? The probability of my donation affecting the funding THL receives from Open Philanthropy could be low, but in expectation the decrease in funding could still be meaningful. To illustrate, if you only adjust your funding to THL in intervals of 100 k$, and set the target funding to THL in $ (instead of as a fraction of THL's total expenditure), a donation of 1 k$ to THL would have something like a 1 % (= 1/100) chance of decreasing your funding by 100 k$ (given a uniform prior about how far away you are from updating you target funding), so the donation would in expectation decrease your funding by 1 k$.
Second, will donating to THL mean that OP gives less to farm animal welfare? Answer: almost certainly not.
I appreciate a donation of 1 k$ is super unlikely to change your animal welfare funding, but this does not necessarily imply the expected change in your animal welfare funding caused by a small donation is neglegible. For example, if you update your targer animal welfare funding in intervals of 100 M$, a 1 k$ donation to THL could have something like a 0.001 % (= 0.001/100) chance of updating your funding by 100 M$ (given a uniform prior about how far away you are from updating you target funding), thus decreasing your animal welfare funding in expectation by 1 k$. Am I missing something?
Thanks Vasco. On (1) and (2), I think that the grant sizing process is messier than it may seem. So the portion of a group's budget we can be is often a major factor, but not necessarily the limiting one. And I don't think our considerations all boil down to us setting a given target revenue for a group, in large part because we don't want to create a perverse incentive for other funders to not fund groups we do and for our grantees to not fundraise.
On (3), I agree there's some chance that in aggregate your donation will flip a group into a different funding category. I just think it's quite rare, because the ideal revenue level for a group is not our only consideration in funding levels. See also the point above about us explicitly trying to avoid gaming other funders or groups' fundraisers.
On the final point, I think you're wrong to assume that if funding for farm animal welfare increased by $100M then there's a 100% chance our program's funding would decline by $100M (which to be clear is more than our program's budget). I think reduced neglect could influence Open Phil leadership to allocate less funding to a cause area. But I think the odds it did so are much below 100% and the amount it would do so by is far less than the increased funding in the space (here $100M).
Thanks, Lewis!

But I think the odds it did so are much below 100% and the amount it would do so by is far less than the increased funding in the space (here $100M).
I gave a bad example because 100 M$ is a significant fraction of the amount granted in farm animal welfare over the number of years respecting the budget allocation. I also assumed an elasticity of 1, but I can see something like 0.5 would be more reasonable. So my corrected statement would be something like a new animal welfare donor granting 10 M$ in a similar way to Open Phil (i.e. not just an increase in 10 M$ of funding, which may be poorly allocated) would decrease Open Phil funding in expectation by 5 M$. However, I see your replies to points 1 to 3 would also apply, such that the elasticity may be closer to 1, and therefore one would not need to worry about Open Phil decreasing funding to animal welfare.
Yeah that makes sense. I think you're right that it's plausible that new funding could decrease Open Phil funding in the space. I just think it's low odds, and would only be to a much lower extent than the size of new funding.
Do you think Open Philanthropy's animal welfare grants should have write-ups whose main text is longer than 1 paragraph? I think it would be great if you shared the cost-effectiveness analyses you seem to be doing. In your recent appearance on The 80,000 Hours Podcast (which I liked!), you said (emphasis mine):
Lewis Bollard: Our goal is to help as many animals as we can, as much as we can — and the challenge is working out how to do that.
[...]
If there’s not a track record, if this is maybe more speculative or a longer-term play, we try to vet the path to impact. So we try to look at what are the steps that would be required to get to the long-term goal. How realistic are those steps? Do they logically lead to one another? And what evidence is there about whether we’re on that path, about whether the group has achieved those initial steps? But then there is also some degree of needing to look at plans and just assess plausibly how strong do these plans look? It’s not always possible to pin down the exact numbers. We try as hard as we can to do that, though.
To be clear, the main text of the write-ups of Open Philanthropy’s large grants is 1 paragraph across all areas, not just the ones related to animal welfare. However, I wonder whether there would be freedom for a given area to share more information (in grant write-ups or reports) if the people leading it thought that to be valuable.
I think this is a fair criticism. For now, I think the costs to longer write-ups outweigh the benefits. I see the costs primarily as:
The benefit also feels limited given my sense is that few people would read these write-ups, and most wouldn't have the ability to move significant funding or org decision making based on them. But feel free to make the case for this in the replies!
Thanks, Lewis!
For now, I think the costs to longer write-ups outweigh the benefits.
Instead of writing write-ups with a main text longer than 1 paragraph, have you considered asking prospective grantees to share a version of their application which you could publish? By default, the public application could be the same as the private one to save time, but some parts of this could be anonymised or removed at grantees discretion. Manifund does this, and I think it is a nice way of minimising costs while keeping much of the benefits.
The benefit also feels limited given my sense is that few people would read these write-ups, and most wouldn't have the ability to move significant funding or org decision making based on them.
Do you think GiveWell should also share much less information about their grants? If not, why?
Thanks Vasco. We actually used to share grantees' applications (with their permission) by default. I suspect you can still find them linked on the older grant pages.
My experience was that this significantly limited the information grantees were willing to share in their application, or forced them to create a second application just for sharing. I was also frustrated at how often these were taken out of context. For example, the meat industry used the Guardian's proposal to us to fund content on factory farming (which we posted) as evidence that the Guardian was biased and just in this for the money.
I'm not sure if GiveWell should share less info. But I'd note that they're in a very different position to Open Phil, in that their aim (as I understand it) is to influence individual donors through rigorous analysis. If I thought we could positively influence the donations of lots of individual donors through longer write-ups, I'd probably think it was worth us doing them.
Do you think the nascent field of economics of animal welfare will play a significant role in increasing the spending on animal welfare interventions? To illustrate what I am referring to, I share below the abstracts of 2 pieces of research in that field.
Kevin Kuruc's paper Monetizing the externalities of animal agriculture: insights from an inclusive welfare function (2023):
Animal agriculture encompasses global markets with large externalities from animal welfare and greenhouse gas emissions. We formally study these social costs by embedding an animal inclusive social welfare function into a climate-economy model that includes an agricultural sector. The total external costs are found to be large under the baseline parameterization. These results are driven by animal welfare costs, which themselves are due to an assumption that animal lives are worse than nonexistence. Though untestable—and perhaps controversial—we find support for this qualitative assumption and demonstrate that our results are robust to a wide range of its quantitative interpretations. Surprisingly, the environmental costs play a comparatively small role, even in sensitivity analyses that depart substantially from our baseline case. For the model to find that beef, a climate-intensive product, has a larger total externality than poultry, an animal-intensive product, we must simultaneously reduce the animal welfare externality to 1% of its baseline level and increase climate damages roughly 35-fold. Correspondingly, the model implies both that the animal agriculture sector is much larger than its optimal level and that considerations across products ought to be dominated by animal welfare, rather than climate, effects.
Romain Espinosa's Animals and social welfare (2023):
I propose a framework to evaluate the social gains from policies regarding animals. The model considers both the welfare of animals and humans. The gains in animal welfare are estimated by considering the violations of the animals’ fundamental freedoms weighted for each species. I apply this framework to twenty policy proposals targeting wild, domestic, farmed, and laboratory animals. Although the policies benefit from widespread popular support in France (the annual willingnesses-to-pay range between 15 and 39 Euros per person per year), I show that they have very heterogeneous impacts on animal welfare (valued at between 0.013 and 3618 Euros per person per year). I further show that humans’ willingness-to-pay for policies improving animal welfare is a poor predictor of the effective impact on animal welfare of these policies. I conclude that it is essential to value animal welfare per se in cost-benefit analyses in order to determine the set of welfare-increasing policies.
I'm excited about the growing field of the economics of animal welfare, including research papers like the two you mentioned. I'm not sure the field will play a significant role in increasing the spending on animal welfare interventions (though curious to hear how you see that happening). But I see a number of important other roles it can play:
What are some important lessons or things you've learned on how to do grantmaking well over the past 9 years that you would give to yourself when you were starting at OP?
In no particular order:
What role do you think journalism can play in advancing the cause of farmed animals? Can you think of any promising topics journalists may want to prioritize in the European context in particular, i.e. topics that have the potential to unlock important gains for farmed animals if seriously investigated and publicized?
I think journalism can help farmed animals by reporting regularly on their plight. For an upcoming newsletter, we tracked the number of news articles on factory farming related topics (e.g. farm animal cruelty) against articles on climate change, over the last decade. While both numbers rose, the number of articles on climate change rose at a much faster rate. I think the lack of media coverage of factory farming contributes to political and public apathy on the issue.
I’d especially like to see articles or investigations into the actions of specific corporate and legislative players. Corporate executives and politicians have the most power to stop farm animal cruelty. But they can easily ignore the issue when the media lets them. So I’d like to see more articles asking why specific corporations are underperforming on animal welfare relative to their competitors, or why specific politicians are opposing popular reforms.
What are some common pitfalls in the field of grantmaking that you encountered, and what advice would you give to new philanthropists to avoid them?
I see lots! Here are the ones that first come to mind:
What are 2-3 of the biggest ways you've updated your thinking in terms of what works / strategies to improve farmed animal welfare over the past few years?
Hi Lewis, and thanks for organizing this AMA,
I'm working on the notion of cultural change concerning the animal issue. It seems to me that you don't address this point in your reflections, and if I'm not mistaken, OP doesn't fund any cultural struggle organizations.
However, it seems to me extremely difficult to achieve the profound advances demanded by the situation for farmed or fished animals without challenging the extreme speciesist ideology of our civilization. And if we consider the fate of wild animals, the prospects are dizzying: they are infinitely numerous, and their massively terrible situation (cf. https://wildanimalsuffering.org/) has persisted since sentience appeared on Earth, and could continue for another 600 million years if we do nothing. We could almost call it an S-risk, except it's not a risk, it's a reality that has always existed and could last forever. So there's a lot at stake if humans can help them one day. But that seems hard to imagine unless we move toward a sentientist, non-speciesist civilization, an orientation we can hardly imagine without a major cultural revolution.
It therefore seems to me very important, not to say crucial, both from the medium-term perspective of abolishing animal exploitation, and from the long-term perspective of supporting sentient beings on the planet, to work towards structuring and developing a large-scale pro-sentient cultural effort (on the scale of, for example, the Enlightenment philosophers in the 18th century or the French anticlericals in the 19th century).
If we consider that the suffering involved is almost infinite, it seems to me that cultural struggle should be given greater importance (yes, I know that such an argument is hardly discriminatory and could just as well be used to promote veganism, for example! I'd like to make it clear that I want to distinguish cultural struggle from individual education or awareness-raising alone, also for reasons of effectiveness, since the former plays out on a societal scale and relies on methods that are not generally the same. More on this distinction here).
Anyway, my question is: are you and OP also thinking about this issue, and if so, what conclusions are you coming to, and by what means? If you don't see sufficient interest in directing significant sums towards this type of intervention, why not?
Thanks for the question. I agree that cultural change is important, both for farmed and wild animals. I'm actually thinking about writing a future newsletter on the topic.
Our challenge funding in this area has been identifying funding opportunities that seem likely to influence cultural change on a large scale. As you allude to, it's not clear that a lot of our movement's past efforts at education and awareness-raising have been effective in this goal. And I'm not clear that past movements have achieved this absent a huge organic grassroots movement (civil rights) or huge funding (anti-tobacco) or both (climate change).
What sorts of interventions do you have in mind? And do you see any examples of past success at cultural change in our movement? It's obviously much easier to scale up successful approaches than to hope for the success of untested ones.
I have in mind several different examples of cultural strategies that are well known in France, but probably less so (or not at all) in the US.
- One very effective cultural strategy is that of Paris Animaux Zoopolis / Projet Animaux Zoopolis (https://zoopolis.fr), which deals with wild animals (not RWAS) and liminal animals, but also recreational fishing and farmed fish for restocking rivers, and which, by changing the public's image of animals (e.g. rats), undoubtedly has a general cultural impact that changes the public's view of animals. PAZ uses the cultural (media) impact of its battles to put pressure on political figures (mayors, MPs) and achieve greater cultural effectiveness or even new laws (its other objective): I've written a description of the work of this association, and how it uses cultural struggle very effectively to bring about concrete, sometimes legislative changes. https://docs.google.com/document/d/1Cj2w9xd9vNjNBGuTpe_WNjIi816E_2roIx_FnK6cvug/edit
- A cultural strategy that would be more effective if it had a bit more funding: the organisation of the World Days for the End of Fishing (and Fish Farming: https://end-of-fishing.org) and for the End of Speciesism (https://end-of-speciesism. org), in which about a hundred organisations from all five continents participate each year (Africa is still poorly represented), and whose aim is to penetrate the culture of the animal advocacy movement by proposing that it take part in these World Days and that once a year (while waiting for something better!) it adopt a discourse centred either on the denunciation of speciesism or on the question of aquatic animals (fish, shrimps), elements that the movement hardly takes into account spontaneously. The strategy is cost-effective (one full-time staff member can reach two times a year hundreds of organisations, some of which will then carry out campaigns), but suffers from its limitations: one full-time staff member can't organise each year more than two days of action, nor can he or she better monitor and advise the organisations. The ideal situation would be to organise real campaigns throughout the year, or over two weeks, etc. In short, to have a full-time worker more. See more here:
https://end-of-fishing.org/en/theory-of-change/
https://end-of-fishing.org/en/plans/
https://end-of-fishing.org/en/kpis/
- One cultural and community-building strategy is the Réseau Sentience (Sentience Network), a network of student associations focused on challenging speciesism, promoting sentientism and effective altruism, and vegetalizing university canteens. It currently exists in France, but it would like to export it to the US, India and elsewhere. The network is now run by a small team, and each local branch is autonomous but linked to the network and run by students on a volunteer basis (and the branches are to some extent funded by their universities!) The number of actions carried out is significant, the aim is to occupy cultural space, and many students train as activists and then remain part of the movement, either joining existing organizations or creating new initiatives. See its Theory of Change: https://docs.google.com/document/d/1tpaIfaUrG_7Wyach3O64iYE1fJnai-pgadyyswiXksw/edit
There are other examples, of course, such as annual meetings that are important for the movement itself, magazines and so on.
I think the work done by organizations like Animal Think Tank or Animal Ask, or Social Change Lab, is also very important, in terms of research into cultural change (often linked to political struggles and insitutional change).
Thanks Yves! I'll check out those links and groups.
In your view, what are some of the biggest challenges facing the farmed animal movement today and what is Open Phil doing about them?
I see a few major challenges:
Hi, Lewis, thanks for this AMA.
Hypothetical situation:
Day 1 after OP announces that it will no longer fund animal welfare.
In your opinion, as an expert individual donor and activist,
Thanks for doing this AMA, Lewis!
What's your take on when a promising intervention seems cost-effective enough to be tried? Do you think we should be using something akin to GiveWell's approach, piloting stuff that's estimated to be, e.g., ~10x more cost-effective than further cage-free campaigns, or...? I realise your opinion on this might not correspond to OP's overall stance, but I'd love to hear your thoughts about such existent and upcoming benchmarks and thresholds within EAA. Thank you!
This is a challenging question, since new interventions in our space typically lack any good data on cost-effectiveness. But in general I’d set a much lower bar than ~10X cage-free campaigns. Instead I think a promising intervention is worth trying if it has an expected value at least as good as cage-free campaigns. E.g. If we think there’s a 50% chance a new intervention will fail and a 50% chance it will be 2X cage-free campaigns, I think it’s worth a shot.
It may be worth considering even interventions that seem less cost-effective than marginal cage-free campaigns, say because:
I suppose for most of these, more careful cost-effectiveness modelling can actually capture these benefits. For 2, AIM/Charity Entrepreneurship often models the expected benefits and expected costs, taking into account different benefits and costs conditional on success/scale up and separately conditional on failure/shutdown (with good enough feedback loops). You can also think of this like value of information. For 1 and 3, you can also just include the value of indirect benefits like capacity building and value of information.
Thanks Michael. Yeah I agree with those three categories. In practice we support a lot of interventions with much worse short-term cost-effectiveness than cage-free campaigns, in part for information value, in part so we can scale them up if they do work out, and in part for diversification purposes.
Alexander Berger and Emily Oehlsen described how Open Philanthropy's Global Health and Wellbeing (OP's GHW) cost-effectiveness bar becoming 2 times as high resulted in less future funding for GiveWell's recommendations, but they did not discuss changes to the funding going towards animal welfare interventions. In theory, all animal welfare grants with a cost-effectiveness between OP's previous and current bar would stop being funded. What are these interventions? I think the absence of such interventions would suggest something is not right with OP's prioritisation between human and animal welfare interventions. In this case, at least before the update of OP's cost-effectiveness bar, OP's marginal animal welfare grants would be at least 2 times as cost-effective as OP's marginal GHW human welfare grants, which would be evidence of OP not being cause neutral.
Whoops, I put this answer under the wrong question. Here it is here. I think Emily’s Forum comment from six months ago remains most relevant here. In particular:
To date, we haven’t focused on making direct comparisons between GHW and FAW. Instead, we’ve focused on trying to equalize marginal returns within each area and do something more like worldview diversification to determine allocations across GHW, FAW, and Open Philanthropy’s other grantmaking. In other words, each of GHW and FAW has its own rough “bar” that an opportunity must clear to be funded. While our frameworks allow for direct comparisons, we have not stress-tested consistency for that use case. We’re also unsure conceptually whether we should be trying to equalize marginal returns between FAW and GHW or whether we should continue with our current approach. We’re planning to think more about this question next year.
On your specific question, the raising of OP’s GHW cost-effectiveness bar did not affect animal welfare interventions.
Thanks, Lewis!
On your specific question, the raising of OP’s GHW cost-effectiveness bar did not affect animal welfare interventions.
In this case:
Side note. OP's GHW portfolio includes the focus area farm animal welfare. If interventions in this area are not affected by OP's GHW bar, I think it would be better to say in posts like the one I linked above that the bar being discussed only applies to human welfare interventions. Maybe OP could call it OP's GHW human welfare bar.
Are there any interventions that are specially promising to increase the fraction of philanthropic and governmental spending on animal welfare, which is currently tiny? Relatedly, the Danish Action Plan for Plant-based Foods was published in October 2023. According to Good Food Institute Europe:
The publication of the plan follows the landmark investment of 1 billion kroner (€168 million) to advance plant-based foods announced two years ago, most of which went into a new Fund for Plant-Based Foods. The fund focuses on advancing research into diverse organic crops, and their applications in creating delicious, nutritious plant-based foods.
I wonder to which extent Open Philanthropy is funding interventions that could accelerate the emergence of these types of plans and investments in other countries.
I'm excited to see governments spending more on alternative protein research and farm animal welfare improvements. I agree that accelerating this work is a priority.
On alternative proteins, I wrote a little while back about public support for alt protein R&D and how we can accelerate it. We're supporting groups like the Good Food Institute, Food Frontier, and Danish Vegetarian Foundation to do so.
On animal welfare, I'm excited to see the EU and some European governments (e.g. Denmark, Netherlands, Germany, UK) considering funding farmers to adopt higher welfare practices. Grantees working on this include Compassion in World Farming and the Albert Schweitzer Foundation.
In what ways have your relationships with grantees changed over the years, and how has this influenced your effectiveness as a grantmaker?
Interesting question! I think my relationships with grantees has become more formal / professional over the years, and less informal / friendly. I think a few factors drove this:
I'm not sure if this has made me more or less effective as a grantmaking. On the plus side, it's probably reduced my bias a bit and freed up some time. On the downside, I think I learn less gossip than I used to when I had more informal friendships with grantees, and sometimes this gossip matters to impact. I also miss being friends with such an incredible group of people!
Is there a 2nd generation of corporate campaigns for chicken welfare in the works which would build upon the success of cage-free campaigns (hens) and the Better Chicken Commitment (broilers)?
I hope so one day, but I think it's a long way away because there's still so much scope in cage-free and BCC work. In particular, I view the corporate campaign priorities as:
What do you think about the possibility of regulatory rather than legislative change? It seems like there is a ton of room within existing legislation (humane slaughter act, 28 hour law, the animal welfare act, and horse protection act) to improve enforcement and apply the existing legislation to more species. For example, AWA recently expanded to include non-farm birds--rodents (e.g. used in research) could be next. The humane slaughter act has terrible enforcement and my (possibly incorrect) reading of the law itself is that it leaves room to expand to more species if FSIS decide sto. It also seems like there is a lot of room to improve, for example, the process of how diseased animals are killed, which would fall under APHIS. Why aren't regulatory actions discussed as much as corporate or legislative actions? What are your thoughts on how they can be influenced?
I think there's a lot of potential in regulatory reform, though I'm probably more optimistic about its prospects outside the US. E.g. I think DEFRA in the UK or the European Commission are more likely to make meaningful regulatory changes than the USDA.
My top priority US regulatory reform would be to get the USDA to interpret the Humane Methods of Slaughter Act to apply to birds too. Courts have held that its within the USDA's discretion to decide this, but decades of on-and-off advocacy by HSUS and AWI have failed to get them to do so. I do think it's worth trying again if we get a more sympathetic USDA secretary (I'm confident Vilsack wouldn't do this).
I think the options under the other laws are more limited. My understanding is that few animals are transported for more than 28 hours anymore, so the 28 Hour Law's protections aren't that helpful. And I don't think the Animal Welfare Act or Horse Protection Act could be extended to apply to farm animals (though better enforcement of the AWA could help a lot of lab animals).
Finally, we looked into the potential to move APHIS on the inhumane methods use to kill animals during disease outbreaks. Unfortunately it seemed pretty intractable at the present time.
How has your strategy for assessing potential grants evolved over the years, and what key factors do you now consider that you didn’t before?
Interesting question! I think we've learned a lot over the years, though this is still far from a science. I think the key factors that we now weigh more heavily than we used to are:
In the 80,000 hours interview, you noted that you thought the Animal Protection/Welfare movement ought to embrace being a more political movement. What forms of policy advocacy seem the most promising to you for improvements to nonhuman animals welfare (i.e. pushing specific states to adopt higher legal welfare standards, pushing for federal reforms, pressure on institutions to go plant-based in their catering, etc.)?
I'm most excited about reforms that can affect the largest numbers of animals, which normally means focusing on political reforms in the largest nations and states where such reforms are feasible. I think the following reforms are currently most feasible:
In your recent 80k podcast almost all the work referenced seems to be targeted at the US and EU (except the Farm animal welfare in Asia section).
Our farm animal welfare grantmaking is, by total spend, 37% in Europe, 29% in the US, 24% in Asia, and 9% everywhere else. This represents a tradeoff between scale and tractability. In general we have a much lower bar for funding work outside Europe and the US, especially in the largest Asian countries, because we think their scale justifies long-term investments. But because those countries are currently much harder to achieve change in, that work actually looks less cost-effective than our EU and US funding, which has proven much more tractable. We’re still committed to funding a lot of work internationally, and my hope is that our early investments in these countries can in time help generate more cost-effective opportunities to fund.
Thanks for sharing, Lewis! By "farm animal welfare grantmaking", I guess you mean spending which in Open Philanthropy's (OP's) grants database falls under the focus areas "Alternatives to Animal Products", "Broiler Chicken Welfare", "Cage-Free Reforms" or "Farm Animal Welfare". Do you have data on how many M$ OP spent on these 4 areas together in China in 2023? How about the total philanthropic spending to help farmed animals in China including all sources (not just OP)?
Update on 20 June 2024. I estimate the philanthropic spending to help farmed animals in 2023 was 304 M$, with China accounting for 6.69 M$.
Hi DanteTheAbstract,
You may want to check Open Philanthropy's grants to support farmed animal welfare in Asia.
Thanks for doing this AMA, Lewis! To steal from the suggested questions, what do you think is behind the decline in plant-based meat sales? And what do you think are some good strategies to build career capital in the animal welfare space? Relatedly, what areas in animal welfare change are more skill/talent constrained?
I think the most likely causes of the decline in plant-based meat sales are:
I think some good strategies to build career capital in the animal welfare spare are:
I liked your post
. What do you think the most promising interventions / donation opportunities are for decreasing ignorance of conditions for animals on factory farms?
Are there organizations for example that make videos on animal welfare and A/B test which resonate best with typical people?
We haven’t funded much work around this because we haven’t yet found many interventions that we’re confident are tractable at scale. Traditionally, groups like The Humane League and Mercy for Animals did this (both the videos and the A/B testing), but I think they’ve largely dropped it.
My best bet for a group doing this today would be One Step for Animals. I appreciate their narrow focus on online videos to build concern for chickens, and their thoughtfulness with A/B testing and strategic placements. (One Step is not an OP grantee, but I personally donate to them.)
What is your take of the impact of fishing on animal welfare? When it comes to aquatic lives, why should we only focus on farmed aquatic life, not fishing? Why not prioritise work towards the ban of all fishing, esp. industrial fishing?
Some info: fishing alone is responsible for 90% of all lives killed per year for consumption, fishing is also destroying wild aquatic life habitats more than we destroy lands, and it also is affecting all wild lives that depend on them to survive: it is pretty much the largest ecocide in the world, and it is legalized. All this destruction for less than 2% of humanity's calories intake. Also, its current techniques to kill these animals are extremely cruel, long lasting, and in accumulation, it likely represents more suffering than in fish farms.
I agree with Michael that a ban on all fishing, or even just industrial fishing, seems politically infeasible. I think it's possible that an island nation heavily dependent on tourism might do this, but that would probably just increase the catch of unregulated fishing ships outside of their territorial waters. I don't see any path to the world doing this.
The other complication is that a ban on wild-caught fishing might just increase the spread of aquaculture, which is worse for each fish involved. Most wild-caught and farmed fish demand is interchangeable -- people are just looking to buy fish. If the wild-caught fish becomes unavailable, I'd expect most of that demand to switch to farmed fish, which would fuel an even bigger boom in aquaculture. Sadly I expect that would be even worse for the fish involved :(
We are though funding work to reduce the suffering caused by current fishing methods. I think work to make the experience of capture and slaughter less horrific is really important.
Hello @LewisBollard and @MichaelStJules thank you for your replies. Some answers to your considerations:
Not clear Michael what you mean y saying 'making fishing more sustainable = more fishing, can you elaborate? (Remembering I mention here to ban industrial fishing, not increasing its welfare, which for me is an oxymoron).
Happy to evolve this conversation further with you both. Thanks!
On 7
Aquaculture also uses fished animals to feed their animals: therefore bans that lower fishing efforts can also make aquiculture less interesting to be pursued?
I think this would be true for species caught primarily for fishmeal. While those caught for direct human consumption also contribute to fishmeal/fish oil/feed (through byproducts/processing waste, e.g. OECD/FAO, 2023, Figure 8.4), they seem more likely to compete with rather than support aquaculture overall (World Bank, 2013, Table E.2, scenario 5 Capture growth vs Baseline).
On the other hand, shrimp are major fishmeal consumers, so a decrease in fishmeal even with a decrease in overall fish and invertebrate catch could reduce shrimp farming in particular and the number of animals farmed, even if it increases aquaculture by tonnage. The increase in aquaculture by tonnage could result from an increase in more herbivorous species, like carps, tilapias, catfishes and bivalves. That being said, I'm not confident that it would decrease the number of animals farmed.
On the other hand again, banning fishing, especially for fishmeal, could also promote insect farming for aquafeed. But we could work on that, too.
So, it seems pretty messy.
On point 5
Fishing alone, especially illegal and industrial, already had depleted more than 70% of species (which are being overfished or are on the verge of collapse), it destroys 50x more land annually than deforestation.
Where did you get 70% of (fished?[1]) species are depleted? Or do you mean in the past, but things might be better now? This seems much higher than related numbers I'm familiar with.
It seems that around 66% of stocks that are fished are fished sustainably vs 34% overfished, and 79% of catch by weight comes from sustainably fished stocks vs 21% from overfished (FAO, 2022, Figure 23, Ritchie & Roser, 2021–2024).
"on the verge of collapse" suggests they are likely to collapse, but that isn't obvious, because it's possible to maintain stocks in an overfished/overfishing equilibrium, or governments may intervene to restrict fishing (e.g. seasonal closures, total allowable catch) to protect against collapse when it gets closer. And even if/when there is a collapse, there can be recovery, e.g. like Peruvian anchoveta, which could be supported by government. Of course, recovery may not go well, e.g. NW Atlantic cod.
By land destroyed by fishing, I assume you mean bottom trawling/dredging. Unlike deforestation, this is mostly the same land being affected each year, and recovery could be faster. Governments are also likely to eventually limit bottom trawling separately from fishing as a whole, because it's much less sustainable.
All of this is the result of particular kinds of fishing and management practices. Rather than outright bans, governments will just make fishing more sustainable, and then most of these concerns will no longer apply.
Not clear Michael what you mean y saying 'making fishing more sustainable = more fishing, can you elaborate? (Remembering I mention here to ban industrial fishing, not increasing its welfare, which for me is an oxymoron).
When there's overfishing (high fishing pressure or harvest rate, as the biomass caught divided by current biomass), marginal reductions in fishing pressure allow overfished populations to recover, allowing more fish to be caught in the long run. I elaborate in Sustainable fishing policy increases fishing, and demand reductions might, too. Of course, a total ban is a complete reduction, so should in fact reduce catch in the long run. But I don't think bans are very politically feasible, at least not on a large scale, and instead you're likely to get marginal reductions in fishing pressure, e.g. through total allowable catch or quotas. Furthermore, I'd guess even small local bans (marine protected areas) can sometimes allow for more fishing in the long run, by reducing fishing pressure on groups that migrate and will be fished elsewhere anyway.
Most species are probably not fished much at all. Only about half of the ocean area is fished. Many species in the same fisheries are not fished much or at all. Most of the ocean by depth, especially the mesopelagic zone and regions away from coasts, is almost entirely unfished.
Hello @MichaelStJules,
I am at a conference at the moment, happy to respond when I leave the conference. What I would love to do is to have a session with you once you have an opportunity. I have been talking to organizations such as Faunalytics to have a deeper look into fishing and animal rights and it would be great to have someone like yourself onboard to work on this matter. Is it something you'd like to participate in?
Quick reply on one of the 70% data: sorry, I've made a confusion, as 70% (to be exact, it is 67%) is overfished in Brazil, not worldwide, which is in fact 34%. However, important to mention that the 60% of fish populations that are 'fully exploited to its maximum yield' globally actually means that it these exploited pop. have a much lower quantity of individuals than it originally used to have before exploitation (MSYs vary their limit of % of lower than original pop. per species and locations, however, they consistently are at a significant % lower than original pop. sizes). They're still able to recover YoY, however a significant decrease in their populations is in fact changing the ecosystem balance, naturally.
Even if there are contradictory studies of some fish species growing x decreasing in studies if species are seen in isolation, I'd also encourage you to have a system's thinking approach to this scenario, as studying animals in nature, you need to take the ecosystem context into view: a sudden change of populations of 1 species could generate growth in others, diminishment in others, but in a system's view, this significant disruption changes the scope of the balance and interdependence of species of that particular ecosystem. In ecological terms, this is likely to result in a lower ecossystemic resilience to natural threats (in particular, climate change). I am aware, however, of the huge challenge of researching this ecological view empirically, therefore there is not so many studies taking all of these complex chains of causes and consequences to bear (it would be great to have more funding for such studies!) - but what already is a common agreement is that to protect areas from fishing is proved to increase the biodiversity of an ecosystem, and consequentially improve its resilience (and its ecossystemic role).
About the other requests for more info: I need time for this, but it may be even more productive to work as a group to distill all these data?
What we cannot deny is that this is a yet relatively overlooked and neglected area of debate, and this is surely one of the areas of more direct impact of human influence on lives, suffering and ecosystem interference and collapse.
We should not ignore it for the sake of ambiguous data or moral questionings, but see this as hugely important area of opportunity to investigate further. Let's continue the conversation through pvt message?
Hi Nathalie, on point 3
The thinking that fishing is increasing fish populations is certain on short term, but not true long term. A high spike on prey fish means less of their prey, subsequently, therefore diminishing their populations over time.
I would tentatively guess that this doesn't usually fully reverse the effect on prey fish, only dampens and slightly reverses it, so that their populations still settle higher than without fishing their predators. Furthermore, the food (mostly primary production?) of the prey (mostly crustaceans) of the prey fish should increase, too, which could have the opposite effects. I guess this can lead to algal blooms sometimes, though, which could then reduce all local animal populations.
That being said, I worry about this reasoning anyway, because it treats food webs as quite linear. A species X can eat a species Y and the prey Z of Y.
There are a few studies on the effect of removing a predator from their ecosystem resulting not on increase of fish populations or biodiversity, but in fact, the opposite happening: less biodiversity, lower populations, ecosystem collapse. This can be easily noticed in scenarios before and after implementing a Marine Protected Area - I can share a few studies if this helps, let me know.
By "removing a predator from their ecosystem", do you mean the (near-)complete removal and therefore (near-complete) absence of the predator, or just a reduction in their biomass/populations? The latter seems more representative of fishing to me, especially as management has improved, and local extinction of a predator seems rarer (although it definitely has happened).
I'd be interested in seeing these studies, especially any globally representative aggregates, systematic reviews or meta-analyses to avoid selection bias.
I'll note that Christensen et al., 2014 is a global aggregate (and extrapolation) of simulations (Ecopath models) spanning 100 years (1910-2010), and Bell et al., 2018 is a meta-analysis of observational studies of biomass data across trophic levels, each spanning at least 18 years, and with a mean length of 34 years.
FWIW, it seems reasonably likely that fishing has increased fish populations on the whole, by disproportionately reducing the populations of more predatory species and increasing the populations of their prey. See Christensen et al., 2014 (only considers fish, not invertebrates) and Bell et al., 2018 (very limited in regional representation).
In general, the effects of fishing on welfare seem quite morally ambiguous, when you consider the effects on population sizes across species, tradeoffs between species, uncertainty about whether their lives are overall bad or overall good: The moral ambiguity of fishing on wild aquatic animal populations.
I also suspect efforts to make fishing more sustainable actually just increase fishing, while outright bans seem politically infeasible; see my other recent post Sustainable fishing policy increases fishing, and demand reductions might, too.
Industrial animal agriculture is a system that is supported by a wide variety of factors, from beliefs about animals being a "resource" to the way the political system is structured. In theory, we could coordinate our work so that we targeted numerous different driving forces at the same time, in order to maximally destabilize the existing system and replace it with something better. That could look like working for cultural change while developing alt. proteins and helping farmers to transition out of animal ag., to give a very broad example. You'd probably want to start in one location and then scale up, or something like that.
I can see many practical and conceptual obstacles to this kind of approach, but it also seems to make a lot of sense. What do you think? And as someone with a great overview of the movement, how much of this do you already see happening?
Thanks Rachel. I think there are people trying the kind of holistic systems-change approach you're describing.
I'm personally skeptical that we have anywhere near the resources to globally destabilize the existing factory farming system. (And I think destabilizing it on a more local basis would have little global impact.) I think the primary drivers of factory farming -- especially the demand for cheap meat -- are so deep-rooted and widespread that they would take immense resources to change.
Instead our focus has mostly been on reducing the suffering caused by factory farming, by trying to both reduce the suffering of each animal and reduce the number of animals factory farmed. I think some of the interventions to do so, like developing alt proteins, probably overlap with some of the things you're thinking of.
This announcement was written by Toby Tremlett, but don’t worry, I won’t answer the questions for Lewis.
Lewis Bollard, Program Director of Farm Animal Welfare at Open Philanthropy, will be holding an AMA on Wednesday 8th of May. Put all your questions for him on this thread before Wednesday (you can add questions later, but he may not see them).
Lewis leads Open Philanthropy’s Farm Animal Welfare Strategy, which you can read more about here. Open Philanthropy has given over 400 grants in its Farm Animal Welfare focus area, ranging from $15,000 to support animal welfare training for two veterinary researchers, to a three-year-long $13 million commitment to support Anima International.
Lewis has a BA in Social Studies from Harvard and a Law degree from Yale. Before starting at Open Philanthropy in 2015, he worked as, amongst other things, a Policy Advisor at the Humane Society of the United States.
Things I recommend reading/listening to to find out more about Lewis’s work:
Consider asking Lewis about:
But, as always, ask him anything!
To what extent does Open Philanthropy (OP) use Rethink Priorities' welfare ranges to compare interventions targetting different species? What else does OP use?
OP currently uses the welfare ranges that Luke Muehlhauser produced as part of his 2018 moral patienthood report. He lists species’ ranges here, though we use point estimates he produced internally. Luke’s numbers are steeper / more hierarchical than Rethink’s.
We sometimes test the sensitivity of species-specific grants to using Luke or Rethink’s welfare ranges. So far this hasn’t often been action-guiding, since we’re already primarily funding work focused on the most numerous farmed vertebrates (chicken and fish) and our funding on invertebrate welfare is more limited by other factors.
Thanks, Lewis!
I actually fitted distributions to the moral weights conditional on moral patienthood Luke shared in that post, and multiplied them by Luke's probabilities of moral patienthood given in his 2017 report, and got expected moral weights pretty close to 1 (i.e. similar to that of humans):
Would it be possibe to share the specific point estimates you are using, and how Luke (@lukeprog) obtained them?
I see. That being said, welfare ranges can still affect cause prioritisation?
Sorry, I can’t share our internal numbers. To date, we haven’t focused on making direct comparisons between GHW and FAW. Instead, we’ve focused on trying to equalize marginal returns within each area and do something more like worldview diversification to determine allocations across GHW, FAW, and Open Philanthropy’s other grantmaking. Luke has written about moral weights in the past, we've commissioned more recent work by Rethink Priorities, and we hope to do more research ourselves in the future -- on moral weights and also on other components of BOTECs that would allow comparisons between animal and human focused work (e.g., welfare range, the difference between the number of humans and chickens, respectively, affected by a marginal intervention in each area), as well as our overall framework for making this decision. That said, the timing is TBD.
