This is so cool, thanks for doing this! Top features for me would be: * multi-criteria search (e.g. I want to see al biosec grants made by Open Philanthropy) * CSV download to analyze the grants * standardize cause areas (possibly the first thing since people might not be aware of this) * consider talking to gwwc is it's possible for people to link their accounts and port giving history from there. You could also consider letting people link and list their donations anonymously. Also, how are the grants currently being added? Is it just feeding from the database that Vipul/Issa made ?

The Joshua Greene and Lucius Caviola article about their givingmultiplier.org work has just been published. Here's the abstract:

The most effective charities are hundreds of times more impactful than typical charities. However, most donors favor charities with personal/emotional


A number of recent proposals have detailed EA reforms. I have generally been unimpressed with these - they feel highly reactive and too tied to attractive sounding concepts (democratic, transparent, accountable) without well thought through mechanisms. I...

"Also - I'm using scare quotes here because I am very confused who these proposals mean when they say EA community. Is it a matter of having read certain books, or attending EAGs, hanging around for a certain amount of time, working at an org, donating a set amount of money, or being in the right Slacks?" It is of course a relevant question who this community is supposed to consist of, but at the same time, this question could be asked whenever someone refers to the community as a collective agent doing something, having a certain opinion, benefitting from something etc. For example, you write "They may be interested in community input for their funding, via regranting for example, or invest in the Community". If you can't define the community, you cannot clearly say that someone invested in it. You later speak of "managing the relationship between the community and its most generous funder", but it seems hard to say how this relationship is currently managed if the community is so hard to define.

The idea of effective altruism has taken a lot of negative publicity recently due to its association with FTX. But has this backlash extended to orgs like GiveWell, Animal Charity Evaluators, and Giving Green that aren't as closely associated with FTX?

I've been tracking how many new GWWC pledges are taken each month using this Colab for a while: https://colab.research.google.com/drive/1BR8nrIAVy7BdD7DpmMZ9CdcQZzBoHfUm?usp=sharing [https://colab.research.google.com/drive/1BR8nrIAVy7BdD7DpmMZ9CdcQZzBoHfUm?usp=sharing] Using this single data point, the picture is mixed I'd say, especially once you consider that What We Owe The Future came out in August 2022 and recession fears started at a similar time. There is also some seasonality of pledging around January, so I did year over year % change for 2021-22: Not including January 2023 yet, as it's not over and it also takes some time for people to show up on the list after they take the pledge. There is a longer term plot in the Colab, but it's too ugly to post here and I'm too lazy to fix it. If someone could make a nicer looking bar chart, I would appreciate it.

I've been keeping an overview of the public effective giving ecosystem that I thought would be worth sharing in its own post (I've previously referred to it here). I've noticed people often aren't aware of many of...

Hi Sjir - will definitely be looking to put out funding opportunities for specific charities (whether a CE incubatee of one of our ideas, if that happens, or other existing organizations working in areas our research identified as impactful). In terms of timeline, probably 2H/2023 or else early next year - not too certain on this!
Ok, sounds good, I've added you to the list; looking forward to what CEARCH will come up with!

My sibling deserves full credit for thinking of and writing this post but he doesn't frequent the EA Forum so asked me to post it.

How well-managed are pools of capital used for EA grantmaking? Are they compounding...

I should not the goal is to donate 5% of the portfolio each year. That will let me donate far more than my entire annual income which is currently over $500,000 per year. I love Will McCaskill's "earn to give" strategy but I tweak it to "earn to invest and give." In an upcoming article on Seeking Alpha I'll show how donating 50% of your income is great. But donating 25% of your income to the most effective charities and investing 25% into a low risk ETF based portfolio can result in up to 100x more donations than just donations alone. Donate today, donate even more tomorrow, and donate staggering amounts over your life time. And then turn your portfolio into a perpetual charitable trust in your will. That ensures the effective altruism never stops. For an example of how powerful this can be consider the example of Ben Franklin. Franklin left $1,000 in his will to Philadelphia and Boston with one important proviso. The money had to be invested and half donated to charity after 100 years. Then the other half after 200 years. The second donation to each city, was $13 million each. From $2000 over $26 million donated to charity. That is the power of patient philanthropy. Help those most in need today. Help tens of thousands over your life time. And help millions or billions over centuries. Give thousands and you can help lots of people. Give millions and you can help millions. Give billions and you can change the world. But give trillions over centuries and millennia and you can change everything.

Epistemic status: Speculative at best. I think the general distribution of assets is probably right, but I'm far from a financial expert, so I might not have the best understanding of the portfolios themselves. tl;dr: The biggest pool is Dustin & Cari's portfolio, which probably has comparable performance. Beyond that, most of the money in EA gets spent rapidly, with few long-term assets that can be invested. Based on my very rough and messy reconstruction of committed resources, organization assets and money flows based on public information, the answer is probably yes. Why? If we include committed assets, then the biggest pool of capital used for EA grantmaking is Dustin Moskovitz and Cari Tuna's portfolio, which amounts to over $13bn [https://www.bloomberg.com/billionaires/profiles/dustin-a-moskovitz/#xj4y7vzkg] in what I believe are largely risky, long-run, diversified investments.[1] [#fneodvhevgv2w]My best guess is that these investments probably compound (on the long term) to a rate similar to university endowments, which also tend to have a risky profile optimized for long-run stocks [https://faculty.washington.edu/gilbertt/docs/University%20endowments%20-%20White%20Paper%20-%20Gilbert%20Hrdlicka%20-%2012%20November%202017.pdf] . Now, a substantial part of Dustin and Cari's money has already been transferred to EA organizations, so the next step in the chain would be to check Good Venture's assets (which are controlled by Open Philanthropy). These probably amount to something like $4bn [https://projects.propublica.org/nonprofits/organizations/461008520] based on public filings from 2020.[2] [#fn9cshva9vpsa]Given Good Venture's money flows, it would seem reasonable to expect a good part of this to be invested, but probably not for the long run. The next stop in this train involve the assets being held by (arguably) the biggest foundation in EA, Effective Ventures (the foundation behind CEA, 80k, EA Funds, GWWC and much, much more [https://ev.org/]).

Without knowing more about your resume and background, I strongly suspect that the first priority, for your initial job, is going to be to get experience in a top/impressive firm, and not focus on finding an EA-aligned job until you have a couple years of experience.

Hey Harrison, very interesting project you are working on and I hope it becomes a success! I love the idea of getting high schoolers to think more altruistically! I understand your stated explanation for only selecting private high schools, but have you thought of later expanding to charter or magnet high schools? From EA forums and in-person meetups, I fear EA is already, and further going into, a kind of echo chamber due to it's demographic of wealthy, elite, intellectual circles. Your project can be a great way to expand EA’s demographic. The Harvard economist Roland Fryer has done similar research and projects, but instead money was used to successfully incentivize underrepresented students to academically succeed in charter and public schools. I would suggest checking out his work. Best of luck on your project!

Love it nice one Xavier! I completely agree with you, and I don't see the pledge as even having to have a direct relationship to EA. I think anyone could legitimately sign the pledge outside of any direct EA framework, giving money to whatever was in your opinion was an effective organsation.

A recent post by Simon_M argued that StrongMinds should not be a top recommended charity (yet), and many people seemed to agree. While I think Simon raised several useful points regarding StrongMinds, he didn't engage with the cost-effectiveness analysis of...

I have no right to ask for this, but for comment sections that really get into the weeds technically (and on issues one would expect to be action-relevant for other members of the community), it would be great to have a fairly short, neutral, accessible writeup once the conversation has died down. I suspect there are a number of readers whose statistical background and abilities are not significantly better than mine (I have some graduate research training in sociology, but it was nearly half a lifetime ago). On the other hand, it's not reasonable to ask commenters to write their technically-oriented comments in a way that is accessible to people like me. At present, I think those of us with less technical sophistication are left with something like "There are issues with HLI's methodology, but the extent to which those issues materially affect the bottom line is a subject of disagreement." Maybe that's all that could be said neutrally anyway, and people like me just have to read the comments and draw what conclusions we can?
Fair point! I'll try to to summarize things from my perspective once things have settled a bit more.
That's so reasonable. I think that we can all agree that the analysis was done in an atypical way (perhaps for good reason), that it was not as rigorous as many people expected, and that it had a series of omissions or made atypical analytical moves that (perhaps inadvertently) made SM look better than it will look once that stuff is addressed. I don't think anyone can speak yet to the magnitude of the adjustment when the analysis is done better or in a standard way. But I'd welcome especially Joel's response to this question. It's a critical question and it's worth hearing his take.

Epistemic status: speculative

This is a response to recent posts including Doing EA Better and The EA community does not own its donors' money. In order to make better funding decisions, some EAs have called for democratizing EA's funding systems....

I agree that this is tricky to do, because the processes aren't so well publicly documented. (Not that they should be - funders providing information about their processes make them more gameable, as most government funding is!) I do think that you could have asked more people with knowledge of the process to review the post, and also think that the Survival and Flourishing Fund documents what they do pretty clearly, including both their writeup, and at least one forum post by a reviewer documenting it pretty extensively.
At a pinch, I would say review might be more worthwhile for topics where the work builds on a well-developed but pre-existing body of research. So, funding a graduate to take time to learn about AI Safety full-time as a bridge to developing a project probably wouldn't benefit from a review, but an application to develop a very specific project based on a specific idea probably would. I don't have a sense on how often five-to-low-six-figure grants involve very specific ideas. If you told me they usually don't, I would definitely update against thinking a peer review would be useful in those circumstances.
I have no idea, to be honest. My belief that smaller grants might not be the best trial run for cost-effectiveness is based more on assumptions that (1) highly qualified reviewers might not think reviewing grants in that range is an effective use of their time; and (2) very quick reviews are likely to identify only clearly erroneous exercises of grantmaking discretion. Either assumption could be wrong! But I think at that grant size, the cost-effectiveness profile might be more favorable for a system of peer review under specified circumstances rather than as a automatic practice. Knowing that they were only being asked when there was a greater chance their assistance might be outcome-determinative might help with attracting quality reviewers too.

GWWC lists StrongMinds as a “top-rated” charity. Their reason for doing so is because Founders Pledge has determined they are cost-effective in their report into mental health.

I could say here, “and that report was written in 2019...

I’m belatedly making an overall comment about this post. I think this was a valuable contribution to the discussion around charity evaluation. We agree that StrongMinds’ figures about their effect on depression are overly optimistic. We erred by not pointing this out in our previous work and not pushing StrongMinds to cite more sensible figures. We have raised this issue with StrongMinds and asked them to clarify which claims are supported by causal evidence. There are some other issues that Simon raises, like social desirability bias, that I think are potential concerns. The literature we reviewed in our StrongMinds CEA (page 26 [https://www.happierlivesinstitute.org/report/strongminds-cost-effectiveness-analysis/] ) doesn’t suggest it’s a large issue, but I only found one study that directly addresses this in a low-income country (Haushofer et al., 2020 [https://www.nber.org/papers/w28106]), so the evidence appears very limited here (but let me know if I’m wrong). I wouldn’t be surprised if more work changed my mind on the extent of this bias. However, I would be very surprised if this alone changed the conclusion of our analysis. As is typically the case, more research is needed. Having said that, I have a few issues with the post and see it as more of a conversation starter than the end of the conversation. I respond to a series of quotes from the original post below. If there's confusion about our methodology, that’s fair, and I’ve tried to be helpful in that regard. Regarding our relationship with StrongMinds, we’re completely independent. This is false. Aswe’ve explained before [https://forum.effectivealtruism.org/posts/uY5SwjHTXgTaWC85f/don-t-just-give-well-give-wellbys-hli-s-2022-charity?commentId=e2PyZq2hFqzLEdgdp] , our evaluation of StrongMinds is primarily based on a meta-analysis of psychological interventions in LMICs, which is a distinction between our work and Founders Pledge that means that many of the problems mentioned apply less to our work

Informative to know where donations are currently going. Most common categories:
31 Domestic Needs
26 International Needs
12 Health
10 Medical

I didn't have much time but was interested in what the "International Needs" charities on the list actually do (thanks for sharing this link!), so I asked ChatGPT to describe the top 10 "International Needs" charities from the list (of 26 total in the category). I'm pasting the result below in case anyone is interested. (Also according to ChatGPT, these can be grouped into the following categories: humanitarian aid and disaster relief (3), housing/infrastructure (1), poverty/economic development (3), health and medicine (2), donated goods and materials (1).) The "health" charities seem to mostly be charities that work on eradicating certain diseases/conditions or supporting people with them (like the American Cancer Society). "Medical" includes St. Jude Children's Research Hospital, Mayo Clinic, and other hospitals and institutes. "Domestic Needs" includes Feeding America, United Way Worldwide, Salvation Army, etc. Other categories include "Youth" — e.g. YMCA of the USA, Environment/Animal — e.g. Nature Conservancy, "Education." 10/26 "international needs" charities (described by ChatGPT): Important disclaimer: I haven't checked these descriptions. 1. Direct Relief is a humanitarian aid organization that provides medical assistance to people affected by poverty, disaster, and civil unrest. 2. Good 360 is a nonprofit organization that helps other nonprofits and schools by providing them with donated goods and materials. 3. Habitat for Humanity International is a nonprofit organization that builds and repairs homes for people in need. 4. AmeriCares is a disaster relief and humanitarian aid organization that provides medical assistance and aid to people affected by poverty, disaster, and civil unrest. 5. Compassion International is a Christian organization that provides assistance to children living in poverty, including education and healthcare support. 6. World Vision is a Christian humanitarian organization that h
Thanks for sharing! As for the dozen or so food banks on the list, it's probably worth noting that the bulk of their incoming donations are food products -- e.g., meat and other stuff that is about to expire. Other organizations aren't set up to do anything with those particular donations. So those entries should not be taken at face value as evidence of general popularity among donors.

I am an attorney in a public-sector position not associated with EA, although I cannot provide legal advice to anyone. My involvement with EA so far has been mostly limited so far to writing checks to GiveWell and other effective charities in the Global Health space, as well as some independent reading. I have occasionally read the forum and was looking for ideas for year-end giving when the whole FTX business exploded . . . 

How I can help others

As someone who isn't deep in EA culture (at least at the time of writing), I may be able to offer a perspective on how the broader group of people with sympathies toward EA ideas might react to certain things. I'll probably make some errors that would be obvious to other people, but sometimes a fresh set of eyes can help bring a different perspective.

I first got involved in EA in 2011 when I started the GWWC chapter at the University of Warwick. Since I worked for GWWC, was a software developer, an early employee at Founders Pledge and started a workplace giving startup.

How I can help others

I can likely connect you to people or talk about my experience community building and pitching EA at Founders Pledge, running a very early stage employee giving startup at Tyve and doing Product Management.

I got into EA in 2012.

"Do not avoid suffering or close your eyes before suffering. Do not lose awareness of the existence of suffering in the life of the world. Find ways to be with those who are suffering, including personal contact, visits, images and sounds. By such means, awaken yourself and others to the reality of suffering in the world." - Thích Nhất Hạnh

FTX Future Fund exploratory grantee based in Kuala Lumpur, spending a year trying to find an EA-related job. Previously I spent 6 years doing data analytics, business intelligence and knowledge + project management in various industries (airlines, ecommerce) and departments (commercial, marketing), after majoring in physics at UCLA. 

I've been at the periphery of EA for a long time; my introduction to it in 2014 was via the dead children as unit of currency essay, I started donating shortly thereafter, and I've been "soft-selling" basic EA ideas for years. But I only started actively participating in the community in 2021, when I joined EA Malaysia. Given my career background it perhaps makes sense that my interests center around improving assessment of altruistic impact, and improving decision-making based on that: estimation of value, cost-effectiveness analysis, local priorities research, etc.

Berkeley, CA, USA
Researcher @ Rethink Priorities

I'm Renan Araujo, a Researcher at Rethink Priorities.

I work in the General Longtermism team, where my primary focus involves making sense of how to prioritize among megaprojects and how to operationalize them. Currently (Nov 22), my work leads me to think about scalable movement building in LMIC, which I've been doing with a focus on Brazil and Latin America through Condor Camp.

Previously, I worked as a predoctoral research fellow at the Legal Priorities Project. There, I look into how constitutions protect future generations, what research should be done in space governance, and how extortion law may help reduce s-risks.

In a previous life, I considered following an academic career in criminology, did a master's in criminal justice policy at LSE, led a criminal justice reform volunteer group in Brazil, and earned a law degree.

You can reach out to me through my personal page and my LinkedIn. I'm happy to have 1-1s about various subjects, from career advice to space governance :)

I'm the co-founder and CEO of PolicyEngine, a tech nonprofit that computes the impacts of public policy (policyengine.org). I'm also the founder and president of the UBI Center, a think tank researching universal basic income policies (ubicenter.org).

I first got into EA in 2012: I worked at Google at the time, and Google.org made a grant to GiveDirectly. I've since taken the GWWC pledge and focused my giving on GiveDirectly and GiveWell. I was active in Google's EA group and also MIT's when I went there for grad school in 2020.

I'm also the founder of Ventura County YIMBY, and a volunteer California state coordinator for Citizens' Climate Lobby, a grassroots organization advocating for a national carbon fee-and-dividend policy.

I'm a third-year undergrad in cognitive science; currently testing out research in philosophy (social epistemology) and studying deep learning.

Program Manager @ Centre for Effective Altruism

I am the program manager for the CEA Online team (the group that runs this Forum), which means I do a bit of everything - operations, analysis, support, and anything else that needs doing.  This is my first role in an EA org, and I am new(ish) to EA, so I am keen to meet as many people as I can!  Email me or message me through the Forum, I'll be happy to connect.

I am joining the CEA team from a fintech where I held roles in product management, corporate strategy, and operations, and I spent some obligatory time as a strategy consultant before that.  I also graduated with a degree in cognitive neuroscience which I've never been able to put to practical use but still find fascinating.

Doctor @ National Health Service

I currently work as a doctor near Manchester, England. Right now, I'm working on completing my Foundation training and deciding what I want to do with the rest of my career. Possible candidates, outside of continuing in clinical medicine, are jobs in operations or research at EA-aligned Global Health and Wellbeing organisations, and I'm excited about opportunities in these fields.

I've been involved with EA through volunteering and working for One for the World, attending EAG 2022, the Cause Innovation Bootcamp, the Hi-Med fellowship, and (most importantly) my GWWC pledge to GiveDirectly.
