(part 3; final part)

Second: The GWWC Pledge. You say:

“The GWWC site, for example, claims that from 291 members there will be £72.68M pledged. This equates to £250K / person over the course of their life. Claiming that this level of pledging will occur requires either unreasonable rates of donation or multi-decade payment schedules. If, in line with GWWC's projections, around 50% of people will maintain their donations, then assuming a linear drop off the expected pledge from a full time member is around £375K. Over a lifetime, this is essentially £10K / year. It seems implausible that expected mean annual earnings for GWWC members is of order £100K.”

Again, there are quite a few mistakes:

First, in comments you twice say that “£112.8M” has been pledged rather than “$112.8M”. I know that’s just a typo but it’s an important one.

Second, you say that the GWWC site claims that, “there will be £72.68M pledged” (future tense). It doesn’t, it says, “$112.8mn pledged” (past tense). It’s a pretty important difference – the pledging is something that has happened, not something that will happen. This might partly explain the confusion discussed in point 4, below. Third, and more substantively, you don’t consider the idea, raised in other comments, that some donors might be donating considerably more than 10%, or that some donors might be donating considerably more than the mean. Both are true of GWWC pledgers.

Fourth, you seem to wilfully misunderstand the verb ‘to pledge’. I regularly make the following statement: “I have pledged to give everything I earn above £20 000 p.a. [PPP and inflation-adjusted to Oxford 2009]”. Am I lying when I say that? Using synonyms, I could have said “I promise to give…”, “I commit to give…” or “I sincerely intend to give…”. None of these entail “I am certain that I will donate everything above £20 000 p.a.”. Using my belief that I will earn on average over £42 000 p.a. [PPP and inflation-adjusted to Oxford 2009] over the course of my life, and that I will work until I’m 68, I can infer that I’ve pledged to give over £1 000 000 over the course of my life, which is also something I say. Am I lying when I say that? (Also note that if only 73 people made the same pledge as me, then we would have jointly pledged the current GWWC amount).

Fifth, I don’t know why you took us to use the $100mn pledged figure as an estimate of our impact. In fact you had evidence to the contrary. In a blog post that you cite I said: “As of last March, we’d invested $170 000’s worth of volunteer time into Giving What We Can, and had moved $1.7 million to GiveWell or GWWC top-recommended development charities, and raised a further $68 million in pledged donations. Taking into account the facts that some proportion of this would have been given anyway, there will be some member attrition, and not all donations will go to the very best charities (and using data for all these factors when possible), we estimate that we had raised $8 in realised donations and $130 in future donations for every $1’s worth of volunteer time invested in Giving What We Can.” (emphasis added).

Finally, I think that the GWWC pledge is misleading only if it’s taken to be a measure of our impact. But we don’t advertise it as that. We could try to make it some other number. We could adjust the number downwards, in order to take into account: how much would have been given anyway; member attrition; a discount rate. Or we could adjust the number upwards, in order to take into account: overgiving; real growth of salaries, and inflation. It could also be adjusted downward to take into account that not all donations are to GW or GWWC recommended charities, or (perhaps) upwards to take into account the idea that we will have better evidence about the best giving opportunities in a few years’ time, and thereby be able to donate to charities better than AMF, SCI or DtW. But any number we gave based on these adjustments would be more misleading and arbitrary than the literal amount pledged. It would also be more confusing for the large majority of our website viewers who haven’t thought about things like counterfactual giving or whether the discount rate should be positive or negative over the next few years; they’re used to the social norm which is to advertise pledges as stated. Until you, no-one who does understand issues such as counterfactual giving and discount rates has understood the amount pledged figure as an impact-assessment.

In comments there was some uncertainty about how we come up with the total pledged figure. What we do is as follows. Each member, when they return their pledge form, states a) what percentage they commit to (or, if taking the Further Pledge, the baseline income above which they give everything); b) their birthdate; c) their expected average earnings per annum. Assuming a (conservative) standard retirement age, that allows us to calculate their expected donations. In some cases, members understandably don’t want to reveal their expected earnings. What we used to do, in such cases, is to use the mean earnings of all the other members who have given their incomes. However, when, recently, one member joined with very large expected earnings (pursuing earning to give), we raised the question whether this method suffers from sample bias, because people who expect to earn a lot will be more likely to report. I’m not sure that’s true: I could imagine that people who earn more often don’t want to flaunt that fact. However, wanting to be conservative, we decided instead to use the mean earnings of the country in which the member works.

Bottom Line for Readers If you’re interested in the question of whether 80,000 Hours and Giving What We Can have acted optimally or will act optimally in the future, the answer is simple: certainly not. We inevitably do some things worse than we could have done, and we value your input on concrete suggestions about how our organisations can improve.

If you’re interested in the question of whether $1 invested in 80,000 Hours or Giving What We Can produces more than $1’s worth of value for the best causes, read here, here, here and here and, most of all, contact me for the calculations and, if you’d like, our latest business plan, at will dot crouch at 80000hours.org. So far, I haven’t seen any convincing arguments to the conclusion that we fail to have a ROI greater than 1; however, it’s something I’d love additional input on, as the outside view makes me wary about believing that I work for the best charity I know of.

(part 2) The most important mistakes in the post

Bizarre Failures to Acquire Relevant Evidence As lukeprog noted, you did not run this post by anyone within CEA who had sufficient knowledge to correct you on some of the matters given above. Lukeprog describes this as ‘common courtesy’. But, more than that, it’s a violation of a good epistemic principle that one should gain easily accessible relevant information before making a point publicly.

The most egregious violation of this principle is that, though you say you focus on the idea that donating to CEA has a ROI greater than 1, and though you repeatedly ask for a ‘calculation’ of impact and claim that CEA is not credible for not being able to provide such a calculation, you haven’t contacted me for the calculation of GWWC’s impact per dollar invested. This isn’t something I’ve been shy about — in a blog post that you link to (as well as elsewhere) I prominently describe this calculated impact-assessment, and invite people to contact me if they want the spreadsheet with the calculation. Insofar as this was the cornerstone of your concern, it’s odd that you didn’t contact me for the spreadsheet. Comments on that impact-assessment would have been helpful, but as far as I’m aware you haven’t read it.

Another example is where you suggest that little thought went into the change of the 80,000 Hours’ declaration of intent. Again, this is information that would have been easily accessible via a quick email to me or Ben Todd. As it happens, the declaration has gone through several iterations; there has been discussion on the core 80,000 Hours’ lists; Ben, myself and other have independently written proposals; and we commissioned one of our best interns to research the topic as part of our general marketing strategy. We concluded that having a lower initial barrier to entry was wise, because it would increase the total number of members, allow us to be more mainstream, and increase the total (though not the proportion) of members who make significant changes to their careers and thereby make the world a significantly better place. (We are also currently discussing whether to introduce a further pledge along the lines of “I intend to dedicate my life to whatever does the most good.”) It wouldn’t be an underestimate to say that several person-weeks of thought and research have gone into the pledges.

A further example is where you guess the number of researchers we have. Again, you could have e-mailed for this information, rather than trying to guess on the basis of the names listed on the website. For this reason, you substantially overestimated how many person-hours we command. Between CEA, over the last six months we have had the equivalent of 3.7 full-time staff. The first 2.6 of these started in July last year, another joined in late September and another in January. GWWC currently has the equivalent of two full-time staff; 80,000 Hours has the equivalent of two and a half full-time staff. For this reason (and perhaps also the planning fallacy), I think you severely overestimate the amount of research we could reasonably expect to deliver in that time.

Another example is where you quote the number of people we have on our mailing lists. This is a good example, because it’s one where I spoke incorrectly in Cambridge. I said that one third of Oxford students were on our mailing list; what I should have said was that about 20% of students coming through fresher’s fair were on our mailing list. It’s precisely errors like these — easy to make in the context of an impromptu group discussion — that show the value of making sure that one’s evidence is reliable.

A further example is where you say “it has been stated that GWWC has an internal price of around £1700 for new pledges” and then, in your response to my query about where this number came from, said that it came from Jacob Trefethen — a volunteer at a chapter, and not currently involved with core GWWC and 80k activities. Again, this is not the sort of evidence on which it’s rational to base a critique — when the option of simply asking me or someone else who works on strategy within CEA was merely an email away.

Another example was: “a large fraction of the people involved with 80,000 hours or GWWC behave like dilettantes”… “Nor do they seem to act as if they wish to seriously optimise the world.” But, as far as I know, you know only one person who works at CEA, Adam Casey, who is an unpaid intern, and you have about one hour’s worth of contact with me. I doubt that, if you knew us personally, and not through material written for an audience encountering the ideas of effective altruism for the first time, you would doubt our intention and commitment to "seriously optimise the world" as you put it. Seeing as this is LessWrong, I'll quote Eliezer Yudkowsky (stated in an independent internet conversation on Ycombinator). In response to the question, “What application of $4B would, right now, generate the most utility for humanity?” he replied: “If you know the word "utility", the people who actually seriously try to figure out the answer to that question live at: * http://www.givingwhatwecan.org/ * http://www.givewell.org/ * http://80000hours.org/ ”

Embarrassingly Poor Arguments First: You ask: “For example, the world bank throws ~$43B/year around. Which is easier: To upscale GWWC by a factor of ~17000, or double the mean effectiveness of the World Bank? This should not be a hypothetical question; it should be answered.”

There are a few mistakes here:

First, your comment suggests that you know that we haven’t thought about this. But that’s misleading, because you haven’t ever asked us if we’ve thought about it.

Second, I have no idea where your numbers come from. After searching (inc. here) I still don’t know where $43bn number comes from. And, after trying to figure it out, I also don’t know where your “17 000” figure comes from. GWWC has so far moved $2.5 million and raised $100mn in pledges. Even discounting the literal pledges by 99% and valuing them at $1mn (which would be far too steep in my view), the appropriate figure would be 12 300. So, whatever the basis, 17 000 seems too high.

Third, even neglecting the above points, your figure would only be correct if the cost-effectiveness of the World Bank’s spending were the same as the cost-effectiveness of GWWC top-recommended charities. But we think, and presumably you agree, that the cost-effectiveness of GWWC’s top-recommended charities are significantly better than the World Bank’s mean cost-effectiveness. Aside from anything else, there’s a major difference between donations and loans. Fourth, if you want to maximize impact yours is not the correct question to ask. If it will get progressively harder to grow GWWC, and if one think that the likelihood of achieving either outcome is very low (both reasonable assumptions), then it could be true that (i) it is easier to double the mean effectiveness of the World Bank than to increase GWWC’s size by a factor of 17000 and (ii) that one ought to use one’s marginal time and resources to grow GWWC. The reason these could both be true is that the marginal benefits from growing GWWC are greater than the marginal benefits of trying to double the effectiveness of the World Bank. Given this, it’s unclear why this question “should be answered”. Fifth, the question implicitly neglects the fact that growing GWWC has substantial knock-on benefits, including increasing the ability of some GWWC members to influence major international organisations like the World Bank (see the background on Toby’s activities, above).

In general: i) Starting with something smaller and easier to achieve has instrumental cumulative benefits and option value in a way that staking everything on one big goal does not. ii) Directly doubling the effectiveness of the World Bank – and other similar projects – is not the comparative advantage of existing EAs in Oxford. Given our success generating and mobilising talented altruists, I think the team here will have greater success taking an indirect route than by attempting to do it directly ourselves. We can use e.g. 80,000 Hours to identify precisely those who have or could develop the requisite skills, credentials and values, and provide them the encouragement, information and practical assistance required to get into positions of major influence over aid effectiveness. Finding and convincing someone to pursue this career is much easier than dedicating your entire life to it yourself, which is what led us to set up 80,000 Hours in the first place.

That’s not to say we aren’t open to the idea. It’s one of my main concerns about my current activities. But it’s misleading to suggest that you have good evidence to believe that we haven’t considered it.

(part 1) Summary Thanks once again, Jonathan, for taking the time to write publicly about CEA, and to make some suggestions about ways in which CEA might be falling short. In what follows I’ll write a candid response to your post, which I hope you’ll take as a sign of respect — this is LW and I know that honesty in this community is valued far more than sugarcoating. Ultimately, we’re all aiming here to proportion our beliefs to our evidence, and beating around the bush doesn’t help with that aim.

In your post you raise some important issues — often issues that those within CEA have also been thinking about. In general, however, the methodology by which you researched and wrote your post was poor. For this reason, there are crucial factual errors in your post that could easily have been avoided, and errors of argumentation that border on embarrassing. This is unfortunate. Powerful criticism of CEA’s activities is extremely important to us: in fact, in the absence of more direct forms of feedback (like profit and loss), it’s vital. But writing poorly researched and poorly thought-through criticism adds more noise than signal; this makes it harder for us in the future to distinguish the incisive and well-evidenced criticism from the rest, which just harms everyone.

I’ll mention some of the issues that you’ve raised that I think are important to think about, before going on to detail some of the mistakes you make in your post. I’ll note just now that, because of other commitments, this post will be the last I make on this thread.

Some Important Points

Individuals vs Large Organizations You ask why we focus on individuals, rather than large foundations, or governments, or intergovernmental institutions like the World Bank. This is a good question, and something we wrestle with. Indeed, it’s also something we’ve pursued. The media attention generated by Giving What We Can has provided a platform for Dr Toby Ord, the principal founder of GWWC, to travel to and speak to the UK Secretary of State for Development, the UK’s Department for International Development, the Centre for Global Development, 10 Downing Street, the Disease Control Priorities Network, the WHO and as it happens, the World Bank, about aid cost effectiveness and how to increase it. He has already had some success in this regard, which wouldn’t have been possible without GWWC, and he expects to spend a significant proportion of his career on this issue.

The question of whether to spend marginal resources influencing individuals versus governmental and international organisations is non-trivial to answer: international organisations have larger budgets, but are more difficult to access and more difficult to influence. If you think it obvious that we should be influencing the latter, I’d be interested to know your reasons. Later in this response, I’ll discuss your suggestion in more depth.

Transparency You raised concerns about the transparency of GWWC and 80,000 Hours. I agree that this is something that both organisations could work on. We have taken steps so far in the direction of transparency, especially in making the organisations transparent to donors and potential donors. Both 80k and GWWC have in-depth 6-monthly reviews, where their progress is assessed internally by the trustees (myself, Nick Beckstead and Toby Ord), and externally, by people, often donors, within the effective altruism community who are not closely involved with the running of the organisation. GWWC has posted on this here, and noted that if you wanted to read the reports from the review you are able to request them. 80,000 hours will make a similar post soon.

In addition, at the request of Giles, I opened CEA up for questioning on LessWrong, and wrote a detailed response to the questions posted there. I try to provide in-depth responses to any questions I receive via e-mail. And I provide the spreadsheet and explanation of an in-depth calculation of GWWC’s impact per dollar to anyone who asks (accurate as of ~March 2012 – we plan to do this annually).

One issue in keeping a start-up organisation transparent is that the nature of our activities changes rapidly. The very idea of 80,000 Hours as primarily a service organization, providing free careers advice, was only thought up in early July 2012. People switch positions regularly while we get a better understanding of whose comparative advantage lies where. It’s difficult to be transparent and non-misleading when you know that the facts might change radically within the space of a few months. There are also many things to be done, and investing in increased transparency has to be weighed against raising more money, or pledges, or making more career changes. So far, we’ve focused on being transparent to our donors and potential donors, which I still think is the right call — but it’s important to think about and reassess this on a regular basis. I’d welcome further thoughts on if you think that we’ve made the wrong trade-off here.

Publishing You briefly suggest the idea that we should use publications as a metric of research output. This is also something that’s worth thinking about. Publishing increases one’s academic reputability, and the scrutiny of peer review improves the reliability of one’s research. However, it is far more time-consuming than one might expect, because one has to tailor one’s research to the norms of the journal, and is especially slow if one is publishing within philosophy journals. (A paper of mine was under review for 10 months from one journal.) It also biases research towards ideas that are publishable, even if less important. So it’s a difficult issue.

For reasons of time, GiveWell don’t publish at all (but the resulting lack of peer review is something I’ve raised as a concern about their research); whereas, in order to boost reputation, MIRI are aiming to publish. At the moment, publishing isn’t a high priority for us, but we do some. I’ve published the central argument in favour of earning to give (it’s forthcoming in Ethical Theory and Moral Practice, available here), and I’m planning to write a book on effective altruism over the next year, from which I might publish a few articles. But beyond that, we’d rather focus on getting the ideas right. However, that’s something we could easily be mistaken about, and is worthy of discussion.

With these points noted, I’ll move on to the mistakes made within the post.

Some misleading aspects of the post

Factual Errors I mention these in my other comment on this post.

One other thing to note is that the 80k pledge was never focused on global poverty. The previous declaration was: I declare that I aim to pursue a career as an effective altruist.

This means that I intend to: (i) Devote a significant proportion of my time or resources to helping others. (ii) Use the time or resources I give as effectively as possible in helping others. (iii) Choose my career based at least in part on how it enables me to further my altruistic aims. And prior to that the declaration was: I pledge that, over my lifetime, I will dedicate 10% of my time or money (or any combination of the two) to those causes that I believe will do the most good with the resources I give them. I understand that it is difficult to know the best way of doing good in the world, and so I will choose those cause(s) on the basis of the best evidence that is available to me at the time. Further, I will deliberately pursue a career that will considerably improve my ability to further those causes I believe to be best.

The new declaration is: "I intend, at least in part, to use my career in an effective way to make the world a better place." More discussion on these changes later.

Misleading statements “In recent conversation with Will Crouch”… “In conversation with Will Crouch”… “these discussions” I mention this in my other post but it’s worth repeating. Though your post suggests that we had at least two one-on-one conversations, this never happened. We spoke only during a question-and-answer session after a short talk I gave.

“There wasn't any particular defence of the choice of wording [of the 80k declaration of intent] or any indication that there had been deep thought about precisely what that pledge should constitute.” This is technically true. However, it’s misleading insofar as I wasn’t asked why the declaration of intent was changed, nor was I asked how much time had gone into thinking about revising the declaration of intent.

“The key argument in favour of donating money to CEA which was presented by Will was that by donating $1 to CEA you produce more than $1 in donations to the most effective charities. We present some apparent difficulties with this remaining true on the margin.” This suggests that your post was primarily about difficulties with inferring marginal cost-effectiveness from past average cost-effectiveness. I think that that’s a very important topic (hey, maybe 99.9% of the value of CEA comes from me! In which case marginal cost-effectiveness would be much lower than past average cost-effectiveness), but as far as I can tell in your post you don’t address that issue anywhere.

Hi Jonathan,

First off, thanks for putting so much time into writing this extensive list of questions and doubts you have about CEA. Unlike for-profit activities, we don't have immediate feedback effects telling us when we're doing well and when we're doing badly, so criticism is an important countermeasure to make sure we do things as well as possible. We therefore really welcome people taking a critical eye to our activities.

As the person who wrote the original CEA material here on LessWrong, and the person who you mention above, I feel I should be the one to collate a response to your questions. However, because of other commitments (managing; fundraising; writing my first piece for a magazine column), it will be a few days before I can get this to you in a form I'd feel happy with. I hope that's ok.

Before then I'll just mention a few things in order to make things a bit clearer to the audience.

• In what you wrote a couple of comments made it sound as if you'd had an in-depth conversation with me on these issues; whereas really the context of the only exchange we've had is my giving a short talk to a group of about 15 people, of very varied backgrounds. You asked a few questions and there was discussion afterwards, but this must have only taken up about 10-15 minutes of time. Though I would very much like to, I haven't ever spoken with you or Alexey one-on-one.

• Similarly, in your response to Luke you say that Adam works full-time at CEA. I think there's some disagreement between the two of you on the extent to which he had signed off on the content. But, at any rate, it's worth noting that Adam is an intern at CEA. This means he does contribute a full working week for CEA, but he is not an employee. He's therefore not the person to go when it comes to high-level evaluation of CEA.

• You mention an internal estimate of £1700 for the value of a new pledge. None of us are familiar with this figure, and we're confused about where it could have come from.

• You suggest that CEA has ~4000 people on its mailing lists. The correct figure is less than half that (unless you include TLYCS, which you might have been thinking of, which does have in excess of 4000 on its mailing list).

• You estimate GWWC's research capacity at 6 staff for last year. This is actually more than an order of magnitude higher than the true figure. In fact, the average number of paid employees (full-time equivalent) we have had working on all aspects of 80,000 Hours and Giving What We Can over the last six months is only 3.7.

As a more general point, I think we should also be careful to distinguish whether CEA has acted optimally in terms of utility-maximization (to which the answer is certainly not), and whether it gets a return on investment which is better than 1:1.

In my follow-up comment, I'll talk about some of the many concerns you've raised that we share, and the issues over which we might be making big mistakes. I'll also be able to give a bit more background about our activities, and I'll be able to answer your questions. Thanks again for taking the time to comment.

Best Wishes,

Will

Is there any good introductory "this is the CEA and it's made up of THESE AWESOME ORGANIZATIONS" page that I could link to on Facebook and such? http://www.centreforeffectivealtruism.org/ is rather dry, and requires clicking on links in order to properly find out what the organizations are all about.

Each employee is paid a starting salary of £18 per annum, significantly below market rates for graduates even within the not-for-profit world, and without accounting for the fact that our employees are significantly more qualified than the average graduate.

If it happens that all the good people you find are the sort of fully committed people who would be living on £18/year and donating the rest, then it's probably fine. But if you miss out on good hires because you're paying so far below what others would offer then it could be really harmful.

One idea which I've heard kicked around is paying people what they're worth and hoping that they'll choose to donate much of the money back. I don't know about organizations having tried this.

This is really detailed, and exceeded my expectations! Thank you!

My response was too long to be a comment so I've posted it here. Thanks all!
