I attended only 1 talk aside from the opening and closing session. I filled up most of my time with (a) meetings and office hours with specific goals, (b) conversations with random people, and (c) time to myself. This strategy worked well for me and I'll probably make it a point to attend 0 talks next year.

Through the planned meetings I had, I learned more about (a) career decisions, specifically infosec careers in GCR (b) how to run EA Giving Tuesday better, and (c) prioritizing causes better.

(I'm not arguing any particular position here. Just mentioning some considerations.)

I think tweeting to Jeff Bezos seems fine, though I'd hope that someone's first response would be "I should make sure Effective Giving saw this" rather than "I should tweet my favorite EA charity at him".

Maybe? Although I think there were some advantages to tweeting him directly:

  • He was asking for tweets, not for organizations to reach out to him via some other way.
  • I imagine it's going to be very, very difficult for organizations to get a hold of Bezos, and I don't think his tweet changed that.
  • A grassroots EA tweeting effort could generate maybe 100 tweets from different individuals which was 0.2% of the overall 47k tweets. That seems to have provided a nontrivial chance of getting his attention, which seems net positive if the tweeters are careful about content.

Still, it might be the case that the best course of action would have been to run it by Effective Giving, either beforehand or in addition.

I don't read Ricky Gervais as being entirely unserious, so responding to him might be reasonable.

I think he was partially serious too, but he didn't explicitly ask for suggestions like Bezos did.

Some considerations I'd make before tweeting at him:
* What's his history in this area? Does he have a record of supporting animal charities? Does he Tweet about bacon all the time, making this an obvious joke?

He's very pro-animals.

* Do the PR people at the animal charities I support know about this Tweet? Should they be the ones to send something, if anyone does?

I think they found out about it from my post, or possibly via some other method. There are a number of tweets there by Animal Charity Evaluators, The Humane League, Vegan Outreach, the Nonhuman Rights Project, etc, or from their employees.

* Are people already deluging him with charity suggestions? If so, how can I make my Tweet stand out, if I plan to send one at all?

As noted above, merely increasing the ratio of EA to non-EA tweet replies would likely increase the probability that it gets his attention. There is of course the possibility that the attention is counterproductive if looks like charity spam.

Thanks for sharing your views on this. I'm now updating towards the view of "don't tweet wealthy people about EA unless they explicitly ask for donation suggestions."

Here are some past examples of EAs tweeting wealthy people with donation advice:

  • Jeff Bezos: In this case he's asking for advice, so tweets that are consistent with what he's asking for seem appropriate. For instance, I think I suggested GiveDirectly to him. Do you share this view?
  • Ricky Gervais: This seems like the kind of tweet that EAs should not reply to in your view, since it's a (half-joking?) mention of his intention to donate to help animals, without asking for suggestions. Does that capture your view on this? (Disclaimer: I crossposted this to the Facebook EAA group and may be indirectly responsible for most of the tweets from EAs here. Maybe that was a mistake.)

The Charity Entrepreneurship report doesn't seem to mention that beef cattle spend around half their lives on pasture. They are also including some dairy cattle considerations that don't apply to beef cattle, e.g. tie stalls. I think this might be skewing their report to a more negative estimate than appropriate.

I think creating distinctions between directly causing harm vs allowing harm to be caused is likely to reduce a person's effectiveness at doing good in the world. I think causing harm in an abstract way that doesn't violate social norms is basically OK if it leads to something more good. For instance, if I advocate to a funder to cut funding to a less effective program and use that funding for a more effective program, I am causing harm to the recipients of the program that got cut. I think that's fine and a good thing to do.

Thanks for the feedback! Yes, I agree that many of the considerations for fishmeal and fish oil are similar. I originally wrote this post a long time ago which is why I did not reference your report in it, but I've now included it under "Some useful sources."

A few comments on your report:

  • Your report says: "These days, any of the fish that are farmed more intensively around the world are carnivorous ... " This was confusing on a first read, but I assume that was a typo and you meant many? As far as I know, the vast majority of farmed fish are omnivorous or herbivorous.
  • I don't think it's correct to say that the fishmeal industry is on the decline. This World Bank report projects low growth through 2030. The current numbers are very high as well. Amongst vertebrates used by humans, feed fish are near the top in number of individuals.
  • You mention cultured meat as a possibility. A major obstacle to the competitiveness of cultured meat is the need for very low-cost culture media. See Open Phil's report. To me it seems the approach of growing proteins and fatty acids in yeast, plants, etc. is likely to be relatively more feasible. As you note, companies are working on this already.
  • As of last month, fishmeal prices seem to be far more expensive than the number you mention, at $1470 per metric ton. Soybean meal prices have increased too though, at $353 per metric ton.

I agree with Jim's comment above. As the graph here suggests, the supply of wild fish appears to have been flat since the 90s, and the increase in demand has been met by the supply of farmed fish. So I think it's likely that consumption of wild fish will just cause someone else to consume farmed fish instead.

With regard to fish oil: Most of it originates from small wild fish such as anchovies. There's an entire industry dedicated to harvesting fish oil and fishmeal, and most of it is used as feed for carnivorous farmed fish like salmon. Fish oil seems to be mostly supply constrained as well, and the aquaculture industry is responding by feeding carnivorous fish more plant oils. I've written about this here and here, and should probably move these to the EA Forum now that less polished posts are encouraged.

Thanks for all this work on this! A few comments and questions:

1. I think there's another important benefit that I didn't see mentioned: There's a risk that people's donations may be influenced towards less effective organizations just for the tax deduction. Permitting people to get tax deductions when donating to a wide variety of effective organizations can help mitigate this risk. My guess is that this is a more important consideration than tax deductions providing incentives to donate more.

2. Do Canadian donors already have a way to get tax deductions for donating to EA Funds? It seems like it could be worthwhile to give Canadian donors this option, though the benefits would need to be weighed against any administrative overhead it would create for RC and CEA.

3. Have you thought about permitting something like an optional 5% "tip" when people make their donations to help fund your operations? Perhaps opt-in by default? I have seen this option Crowdfunding websites, for instance. GiveWell also has an optional 10% "tip," though they're opt-out by default, and their value-add is different.

It's also notable that PayPal announced that they were doing a dollar-for-dollar match of up to $500k in donations through the PayPal Giving Fund on Giving Tuesday, separately from the Facebook match.

That post was made on Giving Tuesday itself and the details there are very limited, but I found this post by an organization with a date of Nov 23, along with the match start and end time. I'm going to dig into this some more. Maybe we can ask some EA-aligned organizations signed up for the PayPal Giving Fund if they can keep an eye out for this and give us an early tipoff.

I think improving recruitment could help. I did recruit people in late September 2018 after Facebook dropped a hint that they would do a repeat, but in retrospect it may have helped to focus on recruiting individuals who would be able to commit to 80 hours (or whatever) if necessary.

This might not be so easy though, since I suspect most people with the skills to do this well are already working on other things and would have difficulty sparing that many hours. Perhaps compensation (e.g. through a grant) could help, but I'm not sure.

I also don't think having large numbers of people each working 10 hours would help, because managing, training, and delegating tasks to that many people would be impractical.

Thanks for the suggestion. I already had EA Grants in mind as an option, but it's interesting to know that the EA Meta Fund lists a fundraising project as an example. As William noted, we were more time constrained rather than funding constrained this year. However, I'll keep this in mind as an option for future years if our circumstances change, or if we can come up with effective ways to convert funding into time.

One other complication with applying for a grant is that we wont know whether there's a worthwhile opportunity until a month or so in advance. After that, if there is a worthwhile opportunity, then we'd need to start working immediately. So we'd probably need to apply for a grant early and, if a worthwhile opportunity doesn't materialize, then we'd need to (a) use the grant to work on something else or (b) return it.

Presumably, GWWC did not want to exclude EA cause areas outside of global poverty. Since animal welfare is an EA cause area, presumably it did not want to exclude it.

1-3 applies to nearly all EA cause areas to varying degrees, including global poverty. The difference, of course, is that EA cause areas (including animal welfare) are supported by evidence and reason, while religious outreach is not.

Specifically, "animal cruelty is bad" is a well argued position, making it very different from a religious belief. See Animal Liberation by Peter Singer.

It's common and fully legal in the US for wealthy people to create their own 501(c)(3) private foundations. I don't think this is an issue.

Even for a 501(c)(3) public charity, a wealthy person should be able to donate enough to support 2/3 of its budget without any legal problems, as long as the remaining 1/3 fits the IRS criteria of "public support." And even if that doesn't work out, it just means the 501(c)(3) may have to turn into a private foundation.

On human poverty, GiveWell is one among several very serious actors. It engages very thoroughly in discussions and explanations when diverging views emerge.

The diverging views in the case of the GiveWell example you gave are from respected research organizations Campbell and Cochrane, with all parties arguing in good faith. This was very different from the case of Nathan's criticisms of ACE.

So again I see a small dissenting voice in the otherwise rather monopolistic position of ACE which is being dismissed without due consideration.

But ACE did reply to Nathan Harrison's criticisms:

But again, I want to pause and think about the bigger picture for a while. The fact is that at the time of writing this argument, the organisation Direct Action Everywhere (DxE) had put up a rather comprehensive report explaining that they had come up with the opposite conclusion! (That cage-free reform is actually detrimental to animal wellfare.) I will refrain from discussing it at length here because this comment is already long, but this report of DxE was, in my opinion, dismissed with precious little good argument.

My understanding is that ACE did in fact take DxE's arguments into consideration, and that their relatively pessimistic estimate that cage-free represents a ~5% improvement is informed by many different views, including DxE's arguments that cage-free is harmful. (This is from conversations I've had and I'm not sure if ACE has published this. I agree it would be helpful if ACE published their reasons for this estimate.)

But we have to realize that when it comes to animal suffering, as far as I know ACE is the only game in town.

I'm not sure how you define "the only game in town." There are currently a number of other organizations who do research on effective animal advocacy, including Open Philanthropy, Sentience Institute, Rethink Charity, Faunalytics, Humane Society of the United States, Humane League Labs, Animal Welfare Action Lab, Wild Animal Suffering Research, etc.

I started out with a negative impression of ACE when I found it years ago. Since then, I've seen substantial improvements in their research quality, substantial willingness to update to new evidence, and substantial willingness to publicly state unpopular conclusions (e.g. leafletting has a slightly negative expected value). I was also impressed with the conference they ran in 2016. My overall impression is now positive, and I appreciate their contributions. I'd also suggest putting ACE in context: GiveWell, which generally has a positive reputation, also got off to a rough start.

I agree that ACE still has room to improve, and I appreciate that you have provided constructive feedback in good faith.

With regard to:

In its cost-effectiveness analyses, ACE estimates that their mean estimate of the “proportional improvement in welfare due to cage-free policies” is ~0.05, but provides only a one sentence explanation for this estimate.

I agree that ACE should provide more justification for this estimate, but I think there are a few points worth noting:

  • This is a fairly pessimistic estimate, far more pessimistic than a reasonable reading of De Mol et al 2006. (Of course a negative estimate would be even more pessimistic.)

  • GiveWell also makes some subjective judgements in their cost-effectiveness estimates that are not supported by comprehensive literature reviews, especially regarding moral weights.

With regard to:

In its review of THL’s and Animal Equality’s corporate outreach, ACE relies only on the charities’ self-reported corporate policy successes, which it then discounts by an arbitrary uncertainty factor: ~0.4 for both Animal Equality and THL.

I assume you're referring to the metric "THL's responsibility for changes"? My understanding that this is mostly supposed to reflect the case that it's often the case that multiple charities are involved in securing a given corporate commitment, making it incorrect to assign 100% of the effectiveness to just one charity.

With regard to:

ACE does not check with third party news sources, experts or with the companies themselves on whether the claims of the charities are accurate.

I agree that ACE should do this, but I predict most of the claims would withstand this scrutiny. As I mention here, I found that 15 out of the 22 corporate commitments that CIWF USA was allegedly involved in from January 2016 to March 2017 had some publicly available evidence to support their causal role.

With regard to grassroots outreach, it's worth noting that a large amount of THL's grassroots work in the past few years has been in coordinating in person protests against food corporations. This differs quite a bit from activities like leafletting, so it's understandable that evidence on the effectiveness of leafletting may not be the most relevant consideration to an evaluation of THL's grassroots work. (ACE has published an intervention report on protests earlier this year, which I haven't read yet.)

Thanks for the informative post, Toni!

With regard to:

We do search online for evidence in the news of each charity's achievements. The problem is: there usually is no such evidence, particularly in the field of corporate outreach. Of course, the absence of evidence of a charity's involvement in a corporate campaign is not evidence that the charity was not involved. We've also looked up corporations' press releases announcing their commitments, but these generally do not mention animal charities. (As far as I can remember, I've never seen one that does.) We have little reason to believe that a corporation could or would share detailed information about their decisions with us if we asked them. I don't know who Mr. Halstead has in mind when he mentions checking with "experts," though we've certainly spoken with many experts in corporate campaigning, if that is what he means.

I've found that the causal role of animal charities in corporate commitments is often supported by publicly available evidence. This evidence generally takes one of two forms:

  • Some corporations do name animal charities in their press releases. This often occurs when the charity secured the commitment through a cooperative approach, though it also sometimes occurs after a public campaign.

  • In cases of public campaigns, the timeline of events often provides some evidence of causality. I've found that the following pattern is typical: An animal charity launches a public campaign, leaving historical evidence in the form of a petition, tweets, media coverage, etc. Weeks or months later, the corporation publishes a press release agreeing to the commitment. (For reference, I've found Twitter to be a helpful resource for establishing these timelines.)

For example, here's is a list of corporate commitments that CIWF USA was allegedly involved in for the period from January 2016 to March 2017. (I had originally compiled this back in March 2017.) In 15 of the 22 cases, I found that their causal role was supported by publicly available evidence.

I wonder if the cutoff point is more like 25,000 though, the number of broiler chickens raised in a shed. It's unclear to me whether producers respond to small changes in demand by adjusting the numbers of broilers in a shed or only by adjusting the number of sheds in use.

If the cutoff point is more like 25,000, then this would imply that most veg*ns go their entire lives without preventing the existence of a single broiler through their consumption changes, while a minority prevent the existence of a huge number.

For what it's worth, it seems likely that donations to AMF are similar since their distributions typically cover hundreds of thousands or millions of people.

I agree with a lot of the content here, but I disagree with this suggestion:

The funds could take a similar approach to Giving What We Can – allocate funds to the top charities in their cause area, and donate to those charities on a regular basis until the fund manager comes along and updates the allocation.

If the annual discount rate is 12% and funds are granted out annually, then I believe this implies an average loss of around 6%. But the expected loss of a grant to a default charity vs a carefully selected charity is likely to be far greater than 6%.

I mentioned this in a previous comment, but in case readers missed it:

  • The increase in flock size from December 2015 to December 2017 is far better explained by the US egg industry's recovery from an avian influenza outbreak than by cage-free pledges.

  • Norwood and Lusk (2011) estimate based on price elasticity data that, on the margin, a reduction in demand for 1 conventional egg causes a reduction in supply of 0.91 conventional eggs. But correspondingly, an increase in demand for 1 cage-free egg should lead to an increase in supply of less than 1 cage-free egg. So it's unclear why we should expect the transition to cage-free to increase the number of layer hens. If anything, the increase in prices caused by the transition should reduce the number of layer hens.

The layer hen flock size in December 2015 was unusually low because of an avian flu outbreak, so I don't think changes between December 2015 and December 2017 tell us much about the transition to cage-free.

It's also not clear why we should expect a transition to cage-free to increase the total number of layer hens based on price effects. If a buyer buys one less conventional egg, the expected supply of conventional eggs should fall by less than one because of price effects. On page 223 of Compassion by the Pound (2011), Norwood and Lusk estimate a decline of 0.91 eggs. But correspondingly, if a buyer buys one more cage-free egg, the increase in supply should increase by less than one, let's say 0.91 as well. I think it's a mistake to only consider price effects for the fall demand for conventional eggs for but not for the increase in demand for cage-free eggs. Of course it's fair to be on the lookout for evidence that one effect is stronger than the other, but the increase in egg supply from 2015 to 2017 is far better explained by a recovery from an avian influenza outbreak so I don't think it provides any meaningful evidence on this issue.

And if we consider price effects overall, the fact that cage-free egg production is somewhat more expensive than conventional egg production should cause a small decline in overall demand for eggs.

I think there is a risk that food corporations will renege on their pledges, perhaps arguing that the cage-free egg supply is insufficient. The parameter "Probability that groups will follow through on the pledges that they made" in ACE's estimates appear intended to capture this risk, and this is assigned a probability of 0.75 for THL in 2017. I think this risk underscores the importance of the work the animal organizations plan on follow-up with food corporations to ensure they follow through on their pledges, and that they start the transition early. I think this need for follow-up represents another limitation of ACE's cost-effectiveness estimates, since they assign all the benefits to the year of the pledges even though follow-up work will be required in future years.

I worry that people might misunderstand the views of Sentience Institute from your comment. The Sentience Institute report summarizes arguments for both positive (momentum) and negative (complacency) long-term effects of welfare reforms. But Jacy and Kelly, who run Sentience Institute, are in favor of welfare reforms, although they do believe anti-speciesism has more positive expected value in the long term. [1] And Sentience Institute's survey [2] of EAA researchers similarly indicates strong support for momentum rather than complacency in the long-term.

More broadly, the sign of the long-term effects of all EA interventions are uncertain, and this is not a problem specific to welfare reforms. (Even the sign of the short-term effects of most animal interventions are uncertain.)

I also don't think the statement that "'cage-free' isn't actually much of a real welfare improvement" is a fair summary of the Open Philanthropy's report. The blog post says, for instance: "We continue to believe our grants to accelerate the adoption of cage-free systems were net-beneficial for layer hens ... In addition, it seems clear to us that cage-free systems have much higher welfare potential than battery cage systems – that is, the theoretical highest-welfare hen housing system would not contain cages."

That being said, I think it is fair to say that ACE regards cage-free as a small improvement, since their 2017 cost-effectiveness model assumes that moving one hen to a cage-free facility reduces only 5% as much suffering as preventing the hen from existence. But it's also notable that ACE's cost-effectiveness models still place corporate campaigns and engagement for welfare reforms as the most cost-effective of the interventions in their estimates, even though they adjust for this pessimism.

(Of course the effects could go negative as you suggest, i.e. if they change their mind and decide cage-free increases 5% as much suffering. But again, this problem is not unique to welfare reforms, as evidenced by the observation that ACE's estimates of most interventions have confidence intervals that span the negatives.)

For what it's worth, my own view is that ACE's cost-effectiveness estimates are far too pessimistic about the benefits of cage-free vs battery cages. (Though I also think they're too optimistic about some other assumptions.)
