I am highly grateful to Alexey Morgunov and Adam Casey for reviewing and commenting on an earlier draft of this post, and pestering me into migrating the content from many emails to a somewhat coherent post.
Will Crouch has posted about the Centre for Effective Altruism and in a follow up post discussed questions in more detail. The general sense of the discussion of that post was that the arguments were convincing and that donating to CEA is a good idea. Recently, he visited Cambridge, primarily to discuss 80,000 hours, and several Cambridge LWers spoke with him. These discussions caused a number of us to substantially downgrade our estimates of the effectiveness of CEA, and made our concerns more concrete.
We're aware that our kind often don't cooperate well, but we are concerned that at present CEA's projects are unlikely to cash out into large numbers of people changing their behaviour. Ultimately, we are concerned that the space for high impact meta-charity is limited, and that if CEA is suboptimal this will have large opportunity costs. We want CEA to change the world, and would prefer this happens quickly.
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. We also present more general worries with CEA as an organisation under these headings:
Transparency
Cost effectiveness estimates
Research
80,000 hours
Impact of 80,000 hours advice
Content of 80,000 hours advice
The 80,000 hours pledge
Scope and Goals
Speed of growth
Ambition
Transparency
It is worrying how little of the key information about CEA is publicly available. This makes assessment hard. By contrast to GiveWell, CEA programs are not particularly open about where their money is spent, what their marginal goals are, or what they are doing internally. As presented online, the majority of both 80,000 hours' and GWWC's day to day activity is maintaining blogs. These blogs are not substantial by comparison to, say, OB in terms of their frequency of content or their frequency of insight. Concretely, it does not seem that CEA is being tranparent in the sense of GiveWell.
Qn: How does CEA think its programs would score on a GiveWell assessment?
Qn: Does CEA think that GiveWell’s assessments systemically go wrong?
Qn: Does CEA consider the blogs to be a substantial source of impact? What external assessments or objective data support a claim of impact from the blogs?
Cost effectiveness estimates
As presented online and in person, CEA does not present as having credible models for their future impact. 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.
Qn: On what basis does GWWC assert that its near 300 members are credibly precommitted to donating £72.68M?
Looking at valuing marginal impacts, it would be hoped CEA's programs are better. For example, it has been stated that GWWC has an internal price of around £1700 for new pledges. This does not appear to extend to new programs, or to portions of 80,000 hours. In recent conversation with Will Crouch, he was asked what marginal value was placed on having a new intern in Cambridge (UK). There was no numerate response. Indeed, the assorted estimates do not cohere. If new pledges are worth £10K / year in expectation, and even 10% of the donations flow into CEA, then an intern generating 20 marginal pledges is a winning proposition for CEA at their stated wage level. If the horizon time for 20 pledges from one worker is larger than CEA can afford to wait, then it is not clear that CEA has an effective program for using their interns.
Qn: What does GWWC or 80,000 hours see as the marginal impact of one additional grad student in full time labour?
Qn: What is the horizon against which CEA programs are acting?
On research
The primary less visible activity of both GWWC and 80,000 hours is research. For GWWC, there are questions to be resolved about how best to Earn to Give, whether there are other activities which are less immediately fiscal but of high impact, and broadly how to identify near optimal opportunities for donation. For 80,000 hours, there is a need to establish how to optimise career paths for a broad set of potential terminal goals. Neither project appears to be bearing visible fruit. In conversation with Will Crouch, he observed that 80,000 hours don't know much about the burnout rates of various careers, the wage progressions or the likelihood of career progression.
At present, this means that 80,000 hours is not publicly presenting things which are better than other sources of advice. There is a need for the best current knowledge to be available quickly; there are people who are deciding careers now who are unlikely to do reliably better than average on the basis of the information that 80,000 hours has made public. It seems implausible that new results are reliably coming in so quickly that the time spent publishing the internal state of the art will substantively slow down further improvements. There is a strong sense in which they are being graded on their speed, with publication being the mediator of impact. It also seems plausible that the publishing and research are substantially orthogonal, and would use different people. Hence from the outside, the lack of published concrete advice seems to be a substantial reason to think that there is no internal art.
Qn: What is 80,000 hours producing with their current research time? What is the planned schedule? What constitutes success?
There is a similar concern with the output of GWWC. Of their listed papers, only one (by Toby Ord) is substantive. The remainder are not written as if there is a pressing need to have results that are concise, clear and better than other available materials. For example, there is an extended article on investing vs. giving, and another on the distinction between income and happiness. The former does little more than list factors that might be relevant, with no attempt to discern which of these effects are largest or a sense of what ranges of reasonable looking assumptions give. The second observes correctly that the impact of monetary loss on donors may be overestimated, but then doesn't even question how impacts on recipients should be converted into hedonic terms. As a document, it seems to have been written to convince rather than elucidate truth. Neither paper drives an update to a belief that the current researchers at GWWC are effectively seeking to identify close to optimal opportunities or to reason coherently about the impact of interventions.
More worrying is the absolute lack of material. Whilst the number of active researchers is difficult to discern from the website, it seems plausible that GWWC has had at least 6 people researching for it for at least the last year. There is no matching level of output; in academe one would expect to see several papers per year per person, and the primary claim of GWWC is that there are low hanging fruit in terms of the optimisation of donation and the ability of people to donate. So a priori, if GWWC was efficiently researching, one would expect it to be finding and publicising their results.
Qn: What is GWWC producing with their current research time? What is the planned schedule? What constitutes success?
80,000 Hours
Impact of the 80,000 hours advice
In conversation with Will, he asserted that on the basis of self-reports, something like 20-25% of those involved in 80K have changed or substantially rethought their career choice. This implies immediately that 75-80% haven't, and in practise that number will be higher care of the self-reporting. This substantially reduces the likely impact of 80,000 hours as a program. Indeed, it seems to be a near fatal problem for GWWC, in that if the 80,000 hours population is representative of pledges, then most of the GWWC pledges are earning in line with typical post grads, which makes it much harder to raise the mean value of each pledge to £250K as is required.
Methods of achieving this impact do not seem to be well attested. Will was asked what the internal value of a paid worker in Cambridge might be. A broad response was that it might improve the ability to give advice, but it was not suggested that this was based on hard data. This is a little troubling, because it implies that the effectiveness of 1-1 Skype interventions or 1-1 in person interventions are not known on a per hour basis. Absent this kind of data, it's difficult to see how 80,000 hours can be effectively optimising their impact.
Qn: Does 80,000 hours have data on the relative effectiveness of their activities?
Qn: How does CEA square a lack of reported career changes with GWWC's numbers, given background over-life earnings?
Content of 80,000 hours’ advice
In conversation, earning to give was suggested as being the baseline to measure against. Will noted explicitly that it's hard to know what kinds of careers are substantively better than others in a data-driven way. He was then very quick to hedge that by saying that of course research was valuable, and of course political activism could be valuable, and of course being a program manager at the world bank could be valuable (which would naturally require you do a PhD first), and of course being an entrepreneur could be valuable. It was not suggested that clearly at most one of these was optimal, or that people might ultimately be in a position where they trade off what they would have chosen to do in isolation against world optimising goals. We came away from this with the concern that 80,000 hours is not being epistemically vicious, and so is not willing to say things that might cause people to be unhappy. In particular, it seemed that there was more pressure to preserving the fuzzies that people were getting out of being affiliated to 80,000 hours than there was to make the advice good, and so most potential career paths were deemed to be OK.
Qn: Does 80,000 hours offer information that causes a substantial reduction in the space of careers that are considered optimal?
Qn: How does 80,000 hours square a lack of reported career changes with their advice being good?
The 80,000 hours pledge
It was noted that the pledge had been substantially weakened, to "I intend, at least in part, to use my career in an effective way to make the world a better place.". My recollection says that it used to be more like "I will use my career to most effectively reduce global poverty". There wasn't any particular defence of the choice of wording or any indication that there had been deep thought about precisely what that pledge should constitute.
The core mechanism by which 80,000 hours or GWWC will achieve long term impact has to be maintaining people's desire to act over a long period. In turn, it seems that the primary intermediate goal is to build a strong social structure to encourage adherence to these pledges. The pledges are then the key totems around which a community will be built, and so there should be massive pressure to optimise these and the surrounding social structures. This does not seem to have occurred.
Qn: What are the design decisions behind the pledge, and what motivated the change in pledge?
Qn: To what extent is the wording of the pledge thought to be important?
Scope and goals
Speed of growth
It was stated that around 1/3 of the Oxford undergraduate population (~4000 people) are on the mailing lists. Of that, there are around 300 members and a few dozen are coming to each event. By comparison, enterprising college societies in Cambridge (TMS, TCSS) have well in excess of 1000 undergraduates on their mailing lists, and get 80-100 people to their talks. When TCSS advertised an event to 1/3 of Cambridge, upwards of 600 people attended. From some organisational point of view, 80,000 hours Oxford could probably extract another factor of 5-10 out of its talk attendance. Whilst that won't factor through directly to the pledges, it seems unlikely that there would not be substantial growth there. In both of the Cambridge societies, the operating scale of the society has been doubled in a single year, by ensuring a reliable stream of events and getting networks in place to advertise widely.
It does not seem like the organisations are optimising for growth and retention of a population of attendees. This would provide a pool of people broadly on board with the aims of the organisations, and substantially enriched for likely pledges. It is very plain that such optimisation has not been codified and sent to other new chapters; the Cambridge GWWC chapter does not behave as if such guidance exists.
Qn: What optimisation has GWWC / 80,000 hours attempted in terms of the structure of their chapters?
Ambition
Taking a larger scale view, lots of these concerns ultimately cash out in a concern that a large fraction of the people involved with 80,000 hours or GWWC behave like dilettantes. There is an apparent desire to feel comfortable about career choice, think about dealing with poverty and get involved with 501(c)(3)'s/NGO's/UK charities. However as organisations, they are not behaving as we would expect for a bunch of people that seriously expect to vector hundreds of millions of pounds over the next decade, which is what continued linear growth would imply.
Nor do they seem to act as if they wish to seriously optimise the world. 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 doesn't seem to be an acceptance that large social structures are going to be needed to support GWWC style donation for a lifetime, in the fashion of say the rotary clubs.
Qn: Where does CEA see its projects in 10 years? 20? 40?
(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:
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.
The $43bn figure (the amount the World Bank (WB) lent in 2011) can be found on the WB website here, the factor of 17000 comes (I think) from dividing $43 bn by the expected annual donations from the pledges ($43 bn / ($112 mn in pledges / 45 years of work) ~ 17000).
However, obviously, as you state, doubling the effectiveness of WB activities will not have the same impact as bringing CEA up to the size of the WB, unless one (unrealistically) assumes that the GWWC recommended charities are only twice as effective as the average WB intervention (though ideal...
