Confidence: High, Funding needs: High
Read more ▾Show less ▴I am on the board of CFAR, so there is a direct and obvious conflict. Of course, I am on the board of CFAR exactly because I think this is a worthwhile use of my time, and also because Anna asked me. I’ve been involved in various ways since the beginning, including the discussions about whether and how to create CFAR in the first place.
CFAR is undergoing an attempted revival. There weren’t workshops for many years, for a variety of reasons including safety concerns and also a need to reorient. The workshops are now starting up again, with a mix of both old and new units, and I find much of the new material interesting and potentially valuable. I’d encourage people to consider attending workshops, and also donating.

Oliver Habryka had created a full writeup by that point, so it is included below.
Help promising people to reason more effectively and find high-impact work, such as reducing x-risk.
top reported bottleneck
In our last grant round, I took an outside view on CFAR and said that, in terms of output, I felt satisfied with CFAR's achievements in recruitment, training and the establishment of communal epistemic norms. I still feel this way about those areas, and my writeup last round still seems like an accurate summary of my reasons for wanting to grant to CFAR. I also said that most of my uncertainty about CFAR lies in its long-term strategic plans, and I continue to feel relatively confused about my thoughts on that.
I find it difficult to explain my thoughts on CFAR, and I think that a large fraction of this difficulty comes from CFAR being an organization that is intentionally not optimizing towards being easy to understand from the outside, having simple metrics, or more broadly being legible [1]. CFAR is intentionally avoiding being legible to the outside world in many ways. This decision is not obviously wrong, as I think it brings many positives, but I think it is the cause of me feeling particularly confused about how to talk coherently about CFAR.
Considerations around legibility
Summary: CFAR’s work is varied and difficult to evaluate. This has some good features — it can avoid focusing too closely on metrics that don’t measure impact well — but also forces evaluators to rely on factors that aren’t easy to measure, like the quality of its internal culture. On the whole, while I wish CFAR were somewhat more legible, I appreciate the benefits to CFAR’s work of not maximizing “legibility” at the cost of impact or flexibility.
To help me explain my point, let's contrast CFAR with an organization like AMF, which I think of as exceptionally legible. AMF’s work, compared to many other organizations with tens of millions of dollars on hand, is easy to understand: they buy bednets and give them to poor people in developing countries. As long as AMF continues to carry out this plan, and provides basic data showing its success in bednet distribution, I feel like I can easily model what the organization will do. If I found out that AMF was spending 10% of its money funding religious leaders in developing countries to preach good ethical principles for society, or funding the campaigns of government officials favorable to their work, I would be very surprised and feel like some basic agreement or contract had been violated — regardless of whether I thought those decisions, in the abstract, were good or bad for their mission. AMF claims to distribute anti-malaria bednets, and it is on this basis that I would choose whether to support them.
AMF could have been a very different organization, and still could be if it wanted to. For example, it could conduct research on various ways to effect change, and give its core staff the freedom to do whatever they thought was best. This new AMF (“AMF 2.0”) might not be able to tell you exactly what they’ll do next year, because they haven’t figured it out yet, but they can tell you that they’ll do whatever their staff determine is best. This could be distributing deworming pills, pursuing speculative medical research, engaging in political activism, funding religious organizations, etc.
If GiveWell wanted to evaluate AMF 2.0, they would need to use a radically different style of reasoning. There wouldn’t be a straightforward intervention with RCTs to look into. There wouldn’t be a straightforward track record of impact from which to extrapolate. Judging AMF 2.0 would require GiveWell to form much more nuanced judgments about the quality of thinking and execution of AMF’s staff, to evaluate the quality of its internal culture, and to consider a host of other factors that weren’t previously relevant.
I think that evaluating CFAR requires a lot of that kind of analysis, which seems inherently harder to communicate to other people without summarizing one’s views as: "I trust the people in that organization to make good decisions."
The more general idea here is that organizations are subject to bandwidth constraints - they often want to do lots of different things, but their funders need to be able to understand and predict their behavior with limited resources for evaluation. As I've written about recently, a key variable for any organization is the people and organizations by which they are trying to be understood and held accountable. For charities that receive most of their funding in small donations from a large population of people who don’t know much about them, this is a very strong constraint; they must communicate their work so that people can understand it very quickly with little background information. If a charity instead receives most of its funding in large donations from a small set of people who follow it closely, it can communicate much more freely, because the funders will be able to spend a lot of their time talking to the org, exchanging models, and generally coming to an understanding of why the org is doing what it’s doing.
This idea partly explains why most organizations tend to focus on legibility, in how they talk about their work and even in the work they choose to pursue. It can be difficult to attract resources and support from external parties if one’s work isn’t legible.
I think that CFAR is still likely optimizing too little towards legibility, compared to what I think would be ideal for it. Being legible allows an organization to be more confident that its work is having real effects, because it acquires evidence that holds up to a variety of different viewpoints. However, I think that far too many organizations (nonprofit and otherwise) are trying too hard to make their work legible, in a way that reduces innovation and also introduces a variety of adversarial dynamics. When you make systems that can be gamed, and which carry rewards for success (e.g. job stability, prestige, etc), people will reliably turn up to game them [2].
(As Jacob has written in his post on Unconscious Economics, this doesn’t mean people are consciously gaming your system, but merely that this behavior will eventually transpire. The many causes of this include selection effects, reinforcement learning, and memetic evolution.)
In my view, CFAR, by not trying to optimize for a single, easy-to-explain metric, avoids playing the “game” many nonprofits play of focusing on work that will look obviously good to donors, even if it isn’t what the nonprofit believes would be most impactful. They also avoid a variety of other games that come from legibility, such as job applicants getting very good at faking the signals that they are a good fit for an organization, making it harder for them to find good applicants.
Optimizing for communication with the goal of being given resources introduces adversarial dynamics; someone asking for money may provide limited/biased information that raises the chance they’ll be given a grant but reduces the accuracy of the grantmaker’s understanding. (See my comment in Lynette’s writeup below for an example of how this can arise.) This optimization can also tie down your resources, forcing you to carry out commitments you made for the sake of legibility, rather than doing what you think would be most impactful [3].
So I think that it's important that we don't force all organizations towards maximal legibility. (That said, we should ensure that organizations are encouraged to pursue at least some degree of legibility, since the lack of legibility also gives rise to various problems.)
Do I trust CFAR to make good decisions?
As I mentioned in my initial comments on CFAR, I generally think that the current projects CFAR is working on are quite valuable and worth the resources they are consuming. But I have a lot of trouble modeling CFAR’s long-term planning, and I feel like I have to rely instead on my models of how much I trust CFAR to make good decisions in general, instead of being able to evaluate the merits of their actual plans.
That said, I do generally trust CFAR's decision-making. It’s hard to explain the evidence that causes me to believe this, but I’ll give a brief overview anyway. (This evidence probably won’t be compelling to others, but I still want to give an accurate summary of where my beliefs come from):
Footnotes
[1] The focus on ‘legibility’ in this context I take from James C. Scott’s book “Seeing Like a State.” It was introduced to me by Elizabeth Van Nostrand in this blogpost discussing it in the context of GiveWell and good giving; Scott Alexander also discussed it in his review of the book . Here’s an example from Scott regarding centralized planning and governance:
The centralized state wanted the world to be “legible”, i.e. arranged in a way that made it easy to monitor and control. An intact forest might be more productive than an evenly-spaced rectangular grid of Norway spruce, but it was harder to legislate rules for, or assess taxes on.
[2] The errors that follow are all forms of Goodhart’s Law, which states that “any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.”
[3] The benefits of (and forces that encourage) stability and reliability can maybe be most transparently understood in the context of menu costs and the prevalence of highly sticky wages.

However, LessWrong operates as a completely separate entity with its own fundraising and hiring procedures, and I don't feel any hesitation or pressure to critique CFAR openly because of that relation. Though I find myself a tiny bit more hesitant to speak harshly of specific individuals, simply because I am only working a floor away from the CFAR offices and that does have some psychological effect on me. Though the same was true for CEA while LessWrong was located in the CEA office for a few months, and was true for residents of my group house while LessWrong was located in the living room of my group house for most of the past two years, so I don't think this effect is particularly large.]
I think that CFAR’s intro workshops have historically had a lot of positive impact. I think they have done so via three pathways.
While I do think that CFAR has historically caused a significant amount of impact, I feel hesitant about this grant because I am unsure whether CFAR can continue to create the same amount of impact in the future. I have a few reasons for this:
However, there are some additional considerations that led me to recommending this grant.
In the last year, I had some concerns about the way CFAR communicated a lot of its insights, and I sensed an insufficient emphasis on a kind of robust and transparent reasoning that I don’t have a great name for. I don’t think the communication style I was advocating for is always the best way to make new discoveries, but is very important for establishing broader community-wide epistemic norms and enables a kind of long-term intellectual progress that I think is necessary for solving the intellectual challenges we’ll need to overcome to avoid global catastrophic risks. I think CFAR is likely to respond to last year’s events by improving their communication and reasoning style in this respect (from my perspective).
My overall read is that CFAR is performing a variety of valuable community functions and has a strong enough track record that I want to make sure that it can continue existing as an institution. I didn’t have enough time this grant round to understand how the future of CFAR will play out; the current grant amount seems sufficient to ensure that CFAR does not have to take any drastic action until our next grant round. By the next grant round, I plan to have spent more time learning and thinking about CFAR’s trajectory and future, and to have a more confident opinion about what the correct funding level for CFAR is.
