Retrospective grant evaluations

Research That Can Help Us Improve

EA funders allocate over a hundred million dollars per year to longtermist causes, but a very small fraction of this money is spent evaluating past grantmaking decisions. We are excited to fund efforts to conduct retrospective evaluations to examine which of these decisions have stood the test of time. He hope that these evaluations will help us better score a grantmaker's track record and generally make grantmaking more meritocratic and, in turn, more effective. We are interested in funding evaluations not just of our own grantmaking decisions (including decisions by regrantors in our regranting program), but also of decisions made by other grantmaking organizations in the longtermist EA community.

This list should have karma hidden and entries randomised. I guess most poeple do not read and vote all the way to the bottom. I certainly didn't the first time I read it.

Starting EA community offices

Effective altruism

Some cities, such as Boston and New York, are home to many EAs and some EA organizations, but lack dedicated EA spaces. Small offices in these cities could greatly facilitate local EA operations. Possible uses of such offices include: serving as an EA community center, hosting talks or reading groups, providing working space for small EA organizations, reducing overhead for event hosting, etc.

(Note: I believe someone actually is looking into starting such an office in Boston. I think (?) that might already be funded, but many other cities could plausibly benefit from offices of their own.)

Investment strategies for longtermist funders

Research That Can Help Us Improve, Epistemic Institutions, Economic growth

Because of their non-standard goals, longtermist funders should arguably follow investment strategies that differ from standard best practices in investing. Longtermists place unusual value on certain scenarios and may have different views of how the future is likely to play out. 

We'd be excited to see projects that make a contribution towards producing a pipeline of actionable recommendations in this regard. We think this is mostly a matter of combining a knowledge of finance with detailed views of the future for our areas of interest (i.e. forecasts for different scenarios with a focus on how giving opportunities may change and the associated financial winners/losers). There is a huge amount of room for research on these topics. Useful contributions could be made by research that develops these views of the future in a financially-relevant way, practical analysis of existing or potential financial instruments, and work to improve coordination on these topics.

Some of the ways the strategies of altruistic funders may differ include:

• Mission-correlated investing

Highly effective enhancement of productivity, health, and wellbeing for people in high-impact roles

Effective Altruism

When it comes to enhancement of productivity, health, and wellbeing, the EA community does not sufficiently utilise division of labour. Currently, community members need to obtain the relevant knowledge themselves and do related research, e.g. on health issues, themselves. We would like to see dedicated experts on these issues that offer optimal productivity, health, and wellbeing, as a service. As a vision, a person working in a high-impact role could book calls with highly trained nutrition specialists, exercise specialists, sleep specialists, personal coaches, mental trainers, GPs with sufficient time, and so on, increasing their work output by 50% while costing little time. This could involve innovative methods such as ML-enabled optimal experiment design to figure out which interventions work for each individual.

Note: Inspired by conversations with various people. I won't name them here because I don't want to ask for permission first, but will share the prize money with them if I win something.

Putting Books in Libraries

Effective Altruism
 

The idea of this project is to come up with a menu of ~30 books and a list of ~10000 libraries, and to offer to buy for each library, any number of books from the menu. This would ensure that folks interested in EA-related topics, who browse a library, discover these ideas. The books would be ones that teach people to use an effective altruist mindset, similar to those on this list. The libraries could be ones that are large, or that that serve top universities or cities with large English-speaking populations.

The case for the project is that if you assume that the value of discovering one new EA contributor is $200k, and that each book is read once per year (which seems plausible based on at least one random library) then the project will deliver far greater than the financial costs, of about $20 per book. The time costs would be minimised by doing much of the correspondence with libraries over the space over a short period of weeks to months. It also can serve as a useful experiment for even larger-scale book distributions, and could be replicated in other languages.

Never Again: A Blue-Ribbon Panel on COVID Failures

Biorisk, Epistemic Institutions

Since effective altruism came to exist as a movement, COVID was the first big test of a negative event that was clearly within our areas of concern and expertise. Despite many high-profile warnings, the world was clearly not prepared to meet the moment and did not successfully contain COVID and prevent excess deaths to the extent that should've been theoretically possible if these warnings had been properly heeded. What went wrong?

We'd like to see a project that goes into extensive detail about the global COVID response - from governments, non-profits, for-profit companies, various high-profile individuals, and the effective altruism movement - and understands what the possibilities were for policy action given what we knew at the time and where things fell apart. What could've gone better and - more importantly - how might we be better prepared for the next disaster? And rather than try to re-fight the last war, what needs to be done now for us to better handle a future disaster that may not be bio-risk at all?

Cognitive enhancement research and development (nootropics, devices, ...)

Values and Reflective Processes, Economic Growth

Improving people's ability to think has many positive effects on innovation, reflection, and potentially individual happiness. We'd like to see more rigorous research on nootropics, devices that improve cognitive performance, and similar fields. This could target any aspect of thinking ability---such as long/short term memory, abstract reasoning, creativity---and any stage of the research and development pipeline---from wet lab research or engineering over testing in humans to product development.

Additional notes on cognitive enhancement research:

• Importance:
  • Sign of impact: You already seem to think that AI-based cognitive aids would be good from a longtermist perspective, so you will probably think that non-AI-based cognitive enhancement is also at least positive. (I personally think that's somewhat likely but not obvious and would love to see more analysis on it).
  • Size of impact: AI-based cognitive enhancement is probably more promising right now. But non-AI-based cognitive enhancement is still pretty promising, there is some precedent (e.g. massive benefit

Create and distribute civilizational restart manuals

A number of "existential risks" we are worried about may not directly kill off everybody, but would still cause enough deaths and chaos to make rebuilding extremely difficult. Thus, we propose that people design and distribute "civilizational restart manuals" to places that are likely to survive biological or nuclear catastrophes, giving humanity more backup options in case of extreme diasters.

The first version can be really cheap, perhaps involving storing paper copies of parts of Wikipedia plus 10 most important books sent to 100 safe and relatively uncorrelated locations -- somewhere in New Zealand, the Antarctica research base, a couple of nuclear bunkers, nuclear submarines, etc.

We are perhaps even more concerned about great moral values like concern for all sentient beings surviving and re-emerging than preserving civilization itself, so we would love for people to do further research and work into considering how to preserve cosmopolitan values as well.

SEP for every subject

Epistemic institutions

Create free online encyclopedias for every academic subject (or those most relevant to longtermism) written by experts and regularly updated. Despite the Stanford Encyclopedia of Philosophy being widely-known and well-loved there are few examples from other subjects. Often academic encyclopedias are both behind institutional paywalls and not accessible on sci-hub (e.g. https://oxfordre.com/). This would provide decisionmakers and the public with better access to academic views on a variety of topics. 

Purchase a top journal

Metascience

Journals give bad incentives to academics - they require new knowledge to be written in hard to understand language, without pre-registration at great cost and sometimes focused on unimportant topics. Taking over a top journal and ensuring it incentivised high quality work on the most important topics would begin to turn the scientific system around.

A Longtermist Nobel Prize

All Areas

The idea is to upgrade the Future of Life Award to be more desirable. The prizemoney would be increased from $50k to$10M SEK (roughly $1.1M) per individual to match the Nobel Prizes. Both for prestige, and to make sure ideal candidates are selected, the selection procedure would be reviewed, adding extra judges or governance mechanisms as needed. This would not immediately mean that longtermism has something to match the prestige of a Nobel, but it would give a substantial reward and offer top longtermists something to strive for.

Megastar salaries for AI alignment work

Artificial Intelligence

Aligning future superhuman AI systems is arguably the most difficult problem currently facing humanity; and the most important. In order to solve it, we need all the help we can get from the very best and brightest. To the extent that we can identify the absolute most intelligent, most capable, and most qualified people on the planet – think Fields Medalists, Nobel Prize winners, foremost champions of intellectual competition, the most sought-after engineers – we aim to offer them salaries competitive with top sportspeople, actors and music artists to work on the problem. This is complementary to our AI alignment prizes, in that getting paid is not dependent on results. The pay is for devoting a significant amount of full time work (say a year), and maximum brainpower, to the problem; with the hope that highly promising directions in the pursuit of a full solution will be forthcoming. We will aim to provide access to top AI alignment researchers for guidance, affiliation with top-tier universities, and an exclusive retreat house and office for fellows of this program to use, if so desired.

Longtermist Policy Lobbying Group

Biorisk, Recovery from Catastrophe, Epistemic Institutions, Values and Reflective Processes

Many social movements find a lot of opportunity by attempting to influence policy to achieve their goals . While longtermism can and should remain bi-partisan, there may be many opportunities to pull the rope sideways on policy areas of concern.

We'd like to see a project that attempts to carefully understand the lobbying process and explores garnering support for identified tractable policies. We think while such a project could scale to be very large once successful, anyone working on this project should really aim to start small and tred carefully, aiming to avoid issues around the unilateralist curse and ensuring to not make longtermism into an overly partisan issue. It's likely that longtermist lobbying might also be best done as lobbying for other clear areas related to longtermism but as a distinct idea, such as lobbying for climate change mitigation or lobbying for pandemic preparedness.

Landscape Analysis: Longtermist Policy

Biorisk, Recovery from Catastrophe, Epistemic Institutions, Values and Reflective Processes

Many social movements find a lot of opportunity by attempting to influence policy to achieve their goals - what ought we do for longtermist policy? Longtermism can and should remain bi-partisan but there may be many opportunities to pull the rope sideways on policy areas of concern.

We'd like to see a project that attempts to collect a large number of possible longtermist policies that are tractable, explore strategies for pushing these policies, and also use public opinion polling on representative samples to understand which policies are popular. Based on this information, we could then suggest initiatives to try to push for.

Proportional prizes for prescient philanthropists

Effective Altruism, Economic Growth, Empowering Excetional People

A low-tech alternative to my proposal for impact markets is to offer regular, reliable prizes for early supporters of exceptionally impactful charities. These can be founders, advisors, or donors. The prizes would not only go to the top supporters but proportionally to almost anyone who can prove that they’ve contributed (or where the charity has proof of the contribution), capped only at a level where the prize money is close to the cost of the administrative overhead.

Donors may be rewarded in proportion to the aggregate size of their donations, advisors may be rewarded in proportion to their time investment valued at market rates, founders may be rewarded in proportion to the sum of both.

If these prizes are awarded reliably, maybe by several entities, they may have some of the same benefits as impact markets. Smart and altruistic donors, advisors, and charity serial entrepreneurs can accumulate more capital that they can use to support their next equally prescient project.

High quality, EA Audio Library (HEAAL)

all/meta, though I think the main value add is in AI

(Nonlinear has made a great rough/low quality version of this, so at least some credit/prize should go to them.)

Audio has several advantages over text when it comes to consuming long-form content, with one significant example being that people can consume it while doing some other task (commuting, chores, exercising) meaning the time cost of consumption is almost 0. If we think that broad, sustained engagement with key ideas is important, making the cost of engagement much lower is a clear win. Quoting Holden's recent post:

I think a highly talented, dedicated generalist could become one of the world’s 25 most broadly knowledgeable people on the subject (in the sense of understanding a number of different agendas and arguments that are out there, rather than focusing on one particular line of research), from a standing start (no background in AI, AI alignment or computer science), within a year

What does high quality mean here, and what content might get covered?

• High quality means read by humans (I'm imagining paying maths/compsci students who'll be able to handle mathematical n

Our World in Base Rates

Epistemic Institutions

Our World In Data are excellent; they provide world-class data and analysis on a bunch of subjects. Their COVID coverage made it obvious that this is a very great public good. 

So far, they haven't included data on base rates; but from Tetlock we know that base rates are the king of judgmental forecasting (EAs generally agree). Making them easily available can thus help people think better about the future. Here's a cool corporate example. 

e.g. 

“85% of big data projects fail”; 
“10% of people refuse to be vaccinated because of fearing needles (pre-COVID so you can compare to the COVID hesitancy)”; 
"11% of ballot initiatives pass"
“7% of Emergent Ventures applications are granted”; 
“50% of applicants get 80k advice”; 
“x% of applicants get to the 3rd round of OpenPhil hiring”, "which takes y months"; 
“x% of graduates from country [y] start a business”.

MVP:

Adversarial collaborations on important topics

Epistemic Institutions

There are many important topics, such as the level of risk from advanced artificial intelligence and how to reduce it, among which there are  reasonable people with very different views. We are interested in experimenting with various types of adversarial collaborations, which we define as people with opposing views working to clarify their disagreement and either resolve the disagreement or identify an experiment/observation that would resolve it. We are especially excited about combining adversarial collaborations with forecasting on any double cruxes identified from them. Some ideas for experimentation might be varying the number of participants, varying the level of moderation and strictness of enforced structure, and introducing AI-based aids.

Existing and past work relevant to this space include the Adversarial Collaboration Project, SlateStarCodex's adversarial collaboration contests, and the Late 2021 MIRI Conversations.

Foundational research on the value of the long-term future

Research That Can Help Us Improve

If we successfully avoid existential catastrophe in the next century, what are the best pathways to reaching existential security, and how likely is it? How optimistic should we be about the trajectory of the long-term future? What are the worst-case scenarios, and how do we avoid them? How can we make sure the future is robustly positive and build a world where as many people are flourishing?

To elaborate on what I have in mind with this proposal, it seems important to conduct research beyond reducing existential risk over the next century – we should make sure that the future we have afterwards is good as well. I'd be interested in research following up on subjects like those of the posts:

• "Disappointing Futures" Might Be As Important As Existential Risk - Michael Dickens
• Why I prioritize moral circle expansion over artificial intelligence alignment - Jacy Reese
• The expected value of extinction risk reduction is positive - Jan Brauner and Friederike Grosse-Holz and A longtermist critique of “The expected value of extinction risk reduction is positive”
• Should We Prioritize Long-Term Existential

Focus Groups Exploring Longtermism / Deliberative Democracy for Longtermism

Epistemic Institutions, Values and Reflective Processes

Right now longtermism is being developed within a relatively narrow set of stakeholders and participants relative to the broad set of people (and nonhumans) that would be affected by the decisions we make. We'd like to see focus groups that attempt to engage a more diverse group of people (diversity across many axes including but not limited to race, gender, age, geography, and socioeconomic status) and attempt to explain longtermism to them and explore what visions they have for the future of humanity (and nonhumans). Hopefully through many iterations we can find a way to go across what is likely rather large initial inferential distance to explore how a broader and more diverse group of people would think about longtermism once ideally informed. This can be related to and informed by engaging in deliberative democracy. This also could be helping to initiate what longtermists call "the long reflection".

Political fellowships

Values and Reflective Processes, Empowering Exceptional People

We’re like to fund ways to pull people who don’t run for political office to run for political office. It's like a MacArthur. You get a call one day. You've been selected. You'd make a great public servant, even if you don't know it. You'd get some training, like DCCC and NRCC, and when you run, you get two million spent by the super-PAC run by the best. They've done the analysis. They'll provide funding. They've lined up endorsers. You've never thought about politics, but they've got your back. Say what you want to say, make a difference in the world: run the campaign you don't mind losing. And if you win, make it real.

The Billionaire Nice List

Pro-immigration advocacy outside the United States

Economic Growth

Increasing migration to rich countries could dramatically reduce poverty and grow the world economy by up to 150%. Open Philanthropy has long had pro-immigration reform in the U.S. as a focus area, but the American political climate has been very hostile to and/or polarized on immigration, making it harder to make progress in the U.S. However, other high-income countries might be more receptive to increasing immigration, and would thus be easier places to make progress. For example, according to a 2018 Pew survey, 81% of Japanese citizens support increasing or keeping immigration levels about the same. It would be worth exploring which developed countries are most promising for pro-immigration advocacy, and then advocating for immigration there.

What this project could look like:

1. Identify 2-5 developed countries where pro-immigration advocacy seems especially promising.
2. Build partnerships with people and orgs in these countries with expertise in pro-immigration advocacy.
3. Identify the most promising opportunities to increase immigration to these countries and act on them.

Advocacy organization for unduly unpopular technologies

Public opinion on key technologies.

Some technologies have enormous benefits, but they are not deployed very much because they are unpopular. Nuclear energy could be a powerful tool for enhancing access to clean energy and combating climate change, but it faces public opposition in Western countries. Similarly, GMOs could help solve the puzzle of feeding the global population with fewer resources, but public opinion is largely against them. Cellular agriculture may soon face similar challenges. Public opinion on these technologies must urgently be shifted. We’d like to see NGOs that create the necessary support via institutions and the media, without falling into the trap of partisan warfare with traditional environmentalists.

Building the grantmaker pipeline

Empowering Exceptional People, Effective Altruism

The amount of funding committed to Effective Altruism has grown dramatically in the past few years, with an estimated  $46 billion dollars currently earmarked for EA. With this significant increase in available funding, there is now a greatly increased need for talented and thoughtful grantmakers, who can effectively deploy this money. It's plausible that yearly EA grantmaking could increase by a factor of 5-10x over the coming decade, and this requires finding and training new grantmakers on best practices, as well as developing sound judgement.  We'd love to see projects that build the grantmaker pipeline, whether that's grantmaking fellowships, grantmaker mentoring, more frequent donor lotteries, more EA funds-style organisations with rotating fund managers, and more. 

NB: This might be a refinement of fellowships, but I think it's particularly important.

Market shaping and advanced market commitments

Epistemic institutions; Economic Growth

Market shaping is when an idea can only be jump-started by committed demand or other forces. Operation Warp Speed is the most recent example of market-shaping through advanced market commitments, but it has been used several times for other vaccine development. We are interested in funding work to understand when market-shaping makes sense, ideas for creating and funding market-shaping methods, and specific market-shaping or advanced market commitments in our areas of interest.

Rationalism But For Group Psychology

Epistemic Institutions

LessWrong and the rationalist community have done well to highlight biases and help individuals become more rational, as well as creating a community around this. But most of the biggest things in life are done by groups and organizations.

We'd like to see a project that takes group psychology / organizational psychology and turns it into a rationalist movement with actionable advice to help groups be less biased and help groups achieve more impact, like how the original rationalist movement did so with individuals. We imagine this would involve identifying useful ideas from group psychology / organizational psychology literature and popularizing them in the rationalist community, as well as trying to intentionally experiment. Perhaps this could come up with better ideas for meetings, how to hire, how to attract talent, better ways to help align employees with organizational goals, better ways to keep track of projects, etc.

Wild animal suffering in space

Space governance, moral circle expansion.

Terraforming other planets might cause animals to come to exist in these planets, either because of intentional or unintentional behaviors. These animals might live net negative lives. 

Also, we cannot rule out the possibility that there are already wild "animals" (or any form of sentient beings) who might be suffering from net negative lives in other planets. (this does not relate directly to the Fermi Paradox, which is highly intelligent lives, not lives per se)

Relevant research include:

• Whether wild animals lead net negative or positive lives on earth, under what conditions. And whether this might hold the same in different planets.
• Tracking, or even doing research on using AI and robotics to monitor and intervene with habitats. This might be critical if there planets there are planets that has wild "animals", but are uninhabitable for humans to stay close and monitor (or even intervene with) the welfare of these animals.
• Communication strategies related to wild animal welfare, as it seem to tend to cause controversy, if not outrage.
• Philosophical research, including population ethics, environmental ethics, comparing welfare/suffering between species, moral uncertainty, suffering-focused vs non-suffering focused ethics.
• General philosophical work on the ethics of space governance, in relation to nonhuman animals.

AI alignment prize suggestion: Introduce AI Safety concepts into the ML community

Artificial Intelligence

Recently, there have been several papers published at top ML conferences that introduced concepts from the AI safety community into the broader ML community. Such papers often define a problem, explain why it matters, sometimes formalise it, often include extensive experiments to showcase the problem, sometimes include some initial suggestions for remedies. Such papers are useful in several ways: they popularise AI alignment concepts, pave the way for further research,  and demonstrate that researchers can do alignment research while also publishing in top venues. A great example would be Optimal Policies Tend To Seek Power, published in NeurIPS. Future Fund could advertise prizes for any paper that gets published in a top ML/NLP/Computer Vision conference (from ML, that would be NeurIPS, ICML, and ICLR) and introduces a key concept of AI alignment.

Refining EA communications and messaging

Values and Reflective Processes, Research That Can Help Us Improve

If we want to motivate a broad spectrum of people about the importance of doing good and ensuring the long-term goes well, it's imperative we find out which messages are "sticky" and which ones are forgotten quickly. Testing various communication frames, particularly for key target audiences like highly talented students, will support EA outreach projects in better tailoring their messaging. Better communications could hugely increase the number of people that consume EA content, relate to the values of the EA movement, and ultimately commit their life to doing good. We'd be excited to see people testing various frames and messaging, across a range of target audiences, using methodologies such as surveys, focus groups, digital media, and more.

TL;DR: EA Retroactive Public Good's Funding

In your format:

Deciding which projects to fund is hard, and one of the reasons for that is that it's hard to guess which projects will succeed and which will fail. But wait, startups have solved this problem perfectly: Anybody is allowed to vet a startup and decide to invest (bet) their money on this startup succeeding, and if the startup does succeed, then the early investors get a big financial return.

The EA community could do the same, only it is missing the part where we give big financial returns to projects that turned out good.

This would make the fund's job much easier: They would have to vet which project helped IN RETROSPECT, which is much easier, and they'll leave the hard prediction work to the market.

Context for proposing this

I heard of a promising EA project that is for some reason having trouble raising funds. I'm considering funding it myself, though I am not rich and that would be somewhat broken to do. But I AM rich enough to fund this project and bet on it working well enough to get a Retroactive Public Good grant in the future, if such a thing existed. I also might have some advantage over the EA Fund in vetting this project.

A “Red Team” to rigorously explore possible futures and advocate against interventions that threaten to backfire

Research That Can Help Us Improve, Effective Altruism, Epistemic Institutions, Values and Reflective Processes

Motivation. There are a lot of proposals here. There are additional proposals on the Future Fund website. There are additional proposals also on various lists I have collected. Many EA charities are already implementing ambitious interventions. But really we’re quite clueless about what the future will bring.

This week alone I’ve discussed with friends and acquaintances three decisions in completely different contexts that might make the difference between paradise and hell for all sentient life, and not just in the abstract in the way that cluelessness forces us to assign some probability to almost any outcome but in the sense were we could point to concrete mechanisms along which the failure might occur. Yet we had to decide. I imagine that people in more influential positions than mine have to make similar decisions on almost a daily basis and on hardly any more information.

As a result, the robustness of an intervention has been the key criterion for prioritiza... (read more)

Subsidise catastrophic risk-related markets on prediction markets

Prediction markets and catastrophic risk

Many markets don't exist because there isn't enough liquidity. A fund could create important longtermist markets on biorisk, AI safetry and nuclear war by pledging to provide significant liquidity once created. This would likely still only work for markets resolving in 1-10 years, due to inflation, but still*.

*It has been suggested to run prediction markets which use indices rather than currency. But people have shown reluctance to bet on ETH markets, so might show reluctance here too.

Resilient ways to archive valuable technical / cultural / ecological information
Biorisk and recovery from catastrophe

 In ancient Sumeria, clay tablets recording ordinary market transactions were considered disposable.  But today's much larger and wealthier civilization considers them priceless for the historical insight they offer.  By the same logic, if human civilization millennia from now becomes a flourishing utopia, they'll probably wish that modern-day civilization had done a better job at resiliently preserving valuable information.  For example, over the past 120 years, around 1 vertebrate species has gone extinct each year, meaning we permanently lose the unique genetic info that arose in that species through millions of years of evolution.
There are many existing projects in this space -- like the internet archive, museums storing cultural artifacts, and efforts to protect endangered species.  But almost none of these projects are designed robustly enough to last many centuries with the long-term future in mind.  Museums can burn down, modern digital storage technologies like CDs and flash memory aren't designed to last for centuries, and many...
