Glad you liked it :) I added a sentence about indirect effects in the first paragraph. I see your point about the title but I chose to leave it as it is because:

  1. I think that people don’t expect cost-effectiveness estimates to take all the indirect effects into account anyway. That said, I am afraid of it being misinterpreted as an estimate of what an additional donated dollar would achieve.
  2. However, anyone who would make important decisions based on this estimate would hopefully read more than just the title anyway.
  3. I wanted to grab the attention of some EAs who would not consider helping welfare reforms otherwise (and hence wouldn’t open an article called “Cost-effectiveness estimate of corporate animal welfare campaigns”).
  4. I wanted the result to be prominently featured because I'd rather the common knowledge within EA would be "it affects 9-120 years per dollar but there are many complications and indirect effects" rather than "it's unclear what the cost-effectiveness is". The former at least let’s people compare the scale of the effects with other interventions.
  5. I don’t want to change the title now because it could confuse some forum readers, and make it more difficult to find for readers who remember the old title.

If I were you, I would try to somehow talk to the kind of farmers you would target, and ask if they would grow more cows if all calves were born female, preferably without making it clear why you are asking. I think that no amount of armchair theorizing can substitute that. You might find out about other indirect effects this way as well.

my assumption is that improving welfare will raise costs, and higher costs will cause customers to switch providers. Are you at all worried about companies that follow through going out of business?

The value of Mean years of impact is smaller because I considered companies going bankrupt, but I didn’t think about them being more likely to go bankrupt (or decrease their market share) because of commitments. Note that companies that don’t follow-through (or don’t commit in the first place) will eventually have to face campaigns from animal advocates, which also puts them at a disadvantage. It’s not like animal advocates stop once half of a country is using higher welfare products. However, if a period between campaigns against different competitors is long, this can be a concern. I haven’t heard of anyone complaining about this though.

I wonder if companies that follow-through would be interested in sponsoring legislation that forces their competitors to also improve welfare? That could help solve this problem maybe?

I actually asked someone about this. They said that companies that made commitments stop campaigning against such legislation, but they haven’t heard about food companies sponsoring such legislation. I imagine that it would only make sense for very big food companies and I’m unsure if any company is big enough.

In any case, this might be an argument for people interested in farm animal welfare to concentrate their efforts on improving welfare for one animal product in one country at a time.

Animal activists are focusing on one issue at the time and indeed, Bollard (2017a) claims that this as one of the primary reasons why corporate campaigns are so successful. But we have enough resources to do it in multiple countries at the same time. Also, animal advocates that live in different countries can’t all work on one country at a time, they are better at achieving success in their own country.

people will probably substitute chicken meat with beef & pork to some degree as chicken prices rise

Good point. One could argue that this still would be a win from an animal welfare perspective (although a smaller one) because chicken requires many more hours of suffering per calorie than beef or pork (see and because broilers arguably live in worse conditions. On the other hand, cows and pigs are more complex animals. Also, maybe some people would substitute chicken with fish, which could be even worse. Thinking about this also makes me less excited about campaigns/legislation against veal crates and gestation crates for pigs because they might increase the consumption of chicken. I don’t know how much these reforms increase prices though.

Additionally it might make sense to concentrate on particular industries, e.g., hotels, high-end restaurants, fast food restaurants, etc. Presumably, McDonald’s is more worried about being undercut by Burger King than Marriot.

Also a good point. I don’t know if animal advocates do that.

Of course, I feel fully confident that the true outcome will be somewhere between 0% and 100%, but this result is not that informative when we need to make a call.

If your 90% CI is between 0% and 100%, it can be a little bit informative to put that in the model (preferably with a custom probability distribution), because it would help to distinguish between interventions that help 0-2 animals per dollar spent, and interventions that help 1 animal per dollar spent. You should of course prefer the latter to avoid the optimizer's curse. If you end up not having actual 90% subjective confidence intervals because you want to make things simpler, I guess you should keep that in mind when filling the column for the strength of evidence in your Priority Asks table.

There is one part of the model that I disagree with:

When looking closely at the US cage-free campaigns, only one (Whole Foods) out of
the 20 companies affecting the highest number of hens has switched to cage-free
(though most deadlines are for planned for 2025). Those companies account for
66% of hens that, in theory, would be affected by the campaign. Which means that
companies that met their deadline (average of 54% rate globally, across different
issues), had a smaller impact that the 20 that didn’t follow through. 5% of pledges is
going to affect 66% of hens. That might suggest that enforcement will become more
difficult as reforms become more significant for the animals and more costly to the

You then use this in the model as a piece of evidence about the expected follow-through rate of all corporate commitments:
All other top 20 companies (with a possible exception of Costco which seems to be close to being cage-free anyway) have their deadlines set in the future, as you say, mostly 2025. You can’t say that they did not follow-through, we just have to wait until 2025 and see if they will, nobody expected them to be 100% cage-free this early. If I were you, I would remove this cell from the model.

This is very interesting and useful, thank you!

I’m a little puzzled about how to interpret the results though, and it’s related with a maths problem that I’ve been confused about for a while. However, I have to warn that this is confusing and it might be counterproductive to think about it because of that.

Do you mean that if you start a new campaign for a new ask, then you expect 39% - 50% of companies that make commitments to follow through? If that is the case, the confidence interval seems to be very narrow. My 90% Subjective Confidence Interval (SCI) for that would be 0% - 100%. For example, there can be commitments like stopping chick culling which depend on the creation of new technologies. Scientists might fail to create such technologies in which case it’s 0%. Or they might make them very cheap and then everyone fulfils their commitments (100%).

Another way to interpret the result is that it is your subjective probability that a given company will follow through. But then I’m not sure it makes sense to have a 90% SCI of what your own subjective probability is. What would that even mean? How would you check that the true value is in the confidence interval?

But even if in your cost-effectiveness estimate you would use a point estimate (44%) instead of a SCI (39% - 50%) for the probability, I wouldn’t be sure about how to interpret the results. The result would still be a SCI because you will probably use SCIs in other parts of your calculations. But then that wouldn’t be a 90% SCI of the number of animal affected. It would be a 90% SCI of the expected value of the number of animals affected. But then again, I don’t know how to interpret a 90% SCI of an expected value.

I think that one way to model cost-effectiveness in a way that makes mathematical sense is to have a probability distribution of the percentage of companies that will follow through. The distribution would have some weight on 0%, some weight on 100% and some weight in between. Another way would be to use point estimates everywhere and say that it is an expected value. Of course, no one will die if you mix these two things, but the result might be difficult to interpret.

If anyone thinks that my reasoning here is wrong, I’d be very curious to hear because I encounter this problem quite often nowadays. And currently I am making a cost-effectiveness model of corporate campaigns myself, and I don’t quite know what to do with the uncertainty about following through...

More space per chicken is just one of the requirements. Probably the most important requirement is to use higher welfare breeds, which generally grow more slowly. But there are more requirements regarding lighting, enrichments, etc. You can see the full ask in the European Chicken Commitment. Asks for other regions are similar and can be seen here.

According to the article The Impact of Food Prices on Consumption: A Systematic Review of Research on the Price Elasticity of Demand for Food, the elasticity for poultry in the U.S. is 0.68 (95% confidence interval is 0.44-0.92). This value is based on 23 estimates. Table 1 in the article contains elasticities of other animal products as well. But on a closer look this seems to not be the thing that you are looking for: "we sought to estimate the effects of price changes on consumer demand".

In general, I would say that your friend is right that consuming less chicken might lead to less of a difference in supply than one would naively think, but it still leads to a difference. At least that's my understanding. But I have a very shallow understanding of this topic.

I wanted to write something similar. I saved up the money that I donated by buying cheaper food and living in cheaper places. It all felt a bit pointless when I saw that the orgs that I donated to spend some of that money on fancy offices in expensive areas. But if I remember correctly, it wasn't a big deal as I continued donating to them. I thought that from an utilitarian POV it could be the right decision on their part.

I also want to say that I'm not sure that I now enjoy my job as a researcher at an EA org more than I enjoyed earning to give as a programmer. I thought that doing something directly meaningful would be much more enjoyable and make me more motivated day-to-day, but it's not happening. I think that what matters more (at least for me) is the nature of the task and whether it's easy to get into a flow.

As for social status, I always felt that even in EA circles (e.g. at EA Globals) it mostly depends on how charismatic/socially smooth you are and that what you do for a living has little impact on it. Maybe it's different in places other than the UK, I don't know. I guess I'm saying all these things because I want to show earning-to-givers that the other side might not be as glamorous as it can seem.

I'm interested in what you think about using subjective confidence intervals to estimate effectiveness of charities and then comparing them. To account for the optimizer's curse, we can penalize charities that have wider confidence intervals. Not sure how it would be done in practice, but there probably is a mathematical method to calculate how much they should be penalized. Confidence intervals communicate both, value and uncertainty at the same time and therefore avoid some of the problems that you talk about.

Voters are important people whose time is valuable, and I'm a bit concerned about the time they spend to decide whom to vote for. For example, I don't want them to read the very long post I've written just to decide whether to vote for it (provided it's not relevant/interesting for them otherwise). I expect them to have more important things to do with their time. I understand that they are not obliged to read it. But being a voter probably puts some pressure on them to read the forum more than they would otherwise, and that might come at the expense of other work. Also, making voting decisions of this kind can be mentally tiring. And if voters don't put much energy into it because they are busy with more important stuff, then wrong posts get selected.

In some cases, fish are released when they are small in size, and then recaptured when they are bigger (this is called sea ranching). This can be economically viable because it's expensive to grow big fish in farms and their mortality rate in the wild is low compared to juveniles. In other cases, they try to augment or (re)create self-sustaining populations which increases the catch in the long term.

Icefish might weigh less than 10 grams, they really look tiny. Also, I see some wild-caught icefish in a fishcount table but it's ten times less in weight than farmed icefish. It could be that these stats don't include all the icefish though.

Fishcount also estimated that each year 0.45-1 trillion wild-caught fish are used to make fishmeal and fish oil, and that between 140 and 490 billion wild-caught fish are fed directly to farmed fish. But all of these fish seem to be wild-caught. This article also seems to assume that (although I only skimmed it). I haven't seen evidence that fish are farmed to feed other farmed fish, I'm not sure if that could be economically viable.

I don't quite understand this estimation. It seems you are comparing Albert Schweitzer Foundation's work with an intervention that improves welfare for farmed food fish (rather than stocked fish)? It seems that the graph includes wild-caught fish. According to a fishcount estimate, in 2015 Germany slaughtered 8-66 million farmed fish. In general, my intuition is that those variables would not be similar to the ones in chicken campaigns.

Also, the full quote from Honglang (2007) is:

According to an investigation report in 2001, there were 16 435 fish seed production units and of these, about 8 072 were well equipped for hatching and juvenile rearing. Total production of all the hatchery is 13 385 billion individuals which meet the need for grow-out production. There are 8 171 hatcheries of the “four major domesticated fish”, 6 700 hatcheries for common carp and crucian carp and 499 for tilapia. The rest of the hatcheries are for river crab (515), reptile (203) and shellfish (1 017).

According to the same article, “four major domesticated fish” are black carp, grass carp, silver carp and bighead carp.

I think this and other sources would mention that most of the fish are of one tiny species that is relatively unimportant commercially and produced by a small number of hatcheries. Or maybe they would exclude them from statistics. But this is not a very strong evidence.

I didn’t know about whitebait. It’s an interesting theory. I haven’t found much information about whitebait/Salangidae farming or fisheries. I only see one species of icefish in fishcount aquaculture statistics - Clearhead icefish (Protosalanx hyalocranius). All of them are produced by China. Fishcount certainly underestimated their numbers by assigning a generic mean weight of 322-1,081 grams. If their mean weight is 10 grams (this is just a guess), there would be 2.1 billion of them produced every year - a lot, but not nearly enough to explain those huge numbers. But there are many tonnes of farmed fish with no species specified in fishcount and it could be that some of them are icefish.

Can we make any inferences about what percent of wild-caught fish were originally stocked in specific areas? Or has any research been done (via tagging, genetic markers, species, etc) to try to estimate that?

Yes, I’ve seen such statistics in many articles. For example, Stopha (2018) claims that “[o]ver the past decade (2008–2017), hatcheries contributed an annual average of about one-third of the total Alaska commercial salmon harvest. By species, Alaska hatchery fish contributed an annual average 66% of the chum, 40% of the pink, 23% of the coho, 20% of the Chinook, and 5% of the sockeye salmon in the total commercial harvest over the decade.” I remember tagging being mentioned as a way to estimate it.

I think that time capping can sometimes be the right decision but I’m also afraid of people overapplying it in research. I remember how I was writing Is the percentage of vegetarians and vegans in the U.S. increasing? I did a couple of days of research, concluded that veg*ism is trending upwards, and planned to share my findings in a short post. I was hoping to finish it in a week. But when writing it up, I realized that some of the evidence was conflicting. Part of me wanted to ignore it so I could get it over with sooner. But sharing analysis with a wrong conclusion can be harmful. So I dug deeper. The week turned into months. My conclusions became more nuanced. I was thinking that if I changed my opinion or found an important piece of evidence yesterday, it would be foolish to stop thinking and searching for more evidence today because the probability of me changing my opinion again is significant. I think that this is a useful heuristic. If I would’ve time-capped, I would’ve published the wrong conclusion. Maybe someone would've later did more research and correct it, but that would’ve required more effort spent on the issue overall, overall research on the topic would be more difficult to comprehend because it would be in multiple places, and some people would hold incorrect opinion despite the new research because they only read my incorrect research.

I once heard the advice that if you are a donor who finds an opportunity that is worth EA money, you should just donate to it, even if you think that you could find a better opportunity after more research. Because if everyone only looks for the very best available opportunity, everyone will have to spend much more time evaluating many projects, or evaluations will be less deep.

The same advice could be adapted to hiring in some cases. If you find an ops person who is good enough to do ops for some EA org, you should consider hiring them, even if you think you could find a better candidate after more search. Because otherwise orgs will have to spend more time evaluating candidates, and candidates will have to spend more time applying.

In other words, having a lower threshold for hiring could be cooperative with other EA orgs in some game-theoretical scenario. Of course, if we go too far in this direction, we will no longer have a good grasp on where the threshold for being hired is, and best people might not get hired. And there are other complications. But EA orgs could go a little bit in this direction.

One complication is that tens of billions of fish are raised in hatcheries for a little bit, and then released into the wild, to enhance wild stocks, so that more fish could be caught later. You could say that they are farmed for a little bit. I am currently writing an article about that.

It seems that meat produced for consumption by dogs and cats normally comes from the very same factory farms that produce human food. Because Animals claims that

Pet foods are made from both 4-D meat (animals that are dead, dying, diseased or disabled), and the leftover bits—referred to on pet food labels as “meat by-products”—of slaughtered farm animals. These parts include the snouts, udders, lungs, feet, organs, ears and other parts that humans don’t want to consume.

Of course, this doesn’t change much. Pet food allows meat industry to be more profitable, which leads to them farming more animals. I agree that this is a strong consideration against having carnivorous pets. There was a discussion about it in the EA forum here.

Unfortunately, the impact of news stories on snake ownership can’t be evaluated because there is not enough data about snake ownership. There is only yearly data for the UK and it has a large margin of error. In other countries there is much less data.
  • I wouldn’t know how recommending alternative snakes could be done effectively. It may also be difficult to do without sending a message that it’s ok to own pet snakes. And yes, I am similarly extremely uncertain about whether that would be an improvement.
  • One day I’d like to look into changing agricultural practices to protect field mice, it does seem to be an important topic. However, it’s not in immediate RP plans.

Glad you liked the post :)

The way I see it, if a cause is big in scale and few people are working on it, there is a significant probability of finding some low-hanging fruits within it. So looking at the scale is useful for determining in which cause areas to look for cost-effective interventions. However, once you have some idea of how cost-effective interventions are, looking at the scale or neglectedness is not very useful.

WAS (Wild Animal Suffering) is a huge problem space, and we are only beginning to explore possible interventions. That doesn't mean that founding WAS charities right now is a good idea. However, it does suggest that searching for effective WAS interventions might be worthwhile.

I think that relevant animal orgs know better whether it's good to outreach to news outlets and how/when to do it, so I will not do it myself.

Some other considerations:

  • Living in the hotel might make people work more because less effort needs to be expanded on taking care of food, having a social life, etc.
  • For some having a place to work around other like-minded people is important for productivity
  • People sometimes learn relevant EA things from each other during daily conversations
  • Living in the hotel might prevent value drift and increase the engagement with EA (this is probably the most important one)

Yes, I initially noticed that as well but forgot to do anything about it. I already have a contact with the person responsible for EggTrack reports, so will tell her. Although it might be too late for them to fix it. Thank you for pointing this out!

I think it depends on the nature of the article. An article that talks negatively about companies that broke their commitments (or did not report progress) can incentivize companies to keep their commitments. The same article could also mention companies that met their commitments.

Hmmm, it would be interesting to organise another event like this where we brainstorm about possible new EA cause areas. Maybe I will do it sometime :-) Or someone else could do it.

The majority of people who took the survey reported being male (68%), while 26% of respondents reported that they were female, and 13% described themselves as other or declined to self-identify

That adds up to more than 100%. I am confused.

I tried to do something similar when deciding where to donate. The most significant difference was step 4. I used neuron count as a multiplier. For example, according to, cows on average have 13.6 times more neurons than chickens. So in my model, one minute of cow's life was 13.6 times more important than one minute of chicken's life of comparable quality. I've seen some people comparing the square root of neuron count instead. makes it easy to make these kinds of comparisons for farm animals.
