Many thanks to Ozzie Gooen for suggesting this project, to Marta Krzeminska for editing help and to Michael Aird and others for various comments. In early 2022, Leo updated the list with new candidates suggested before March 2022, in this post—these have now been incorporated into the main post.

In the last few years, there have been many dozens of posts about potential new EA cause areas, causes and interventions. Searching for new causes seems like a worthy endeavour, but on their own, the submissions can be quite scattered and chaotic. Collecting and categorizing these cause candidates seemed like a clear next step.

At the time we first published this post, we —Ozzie Gooen of the Quantified Uncertainty Research Institute and I—noted that we might later be interested in expanding this work and eventually using it for forecasting —e.g., predicting whether each candidate would still seem promising after much more rigorous research. At the same time, we felt like the original list itself could be useful already. Since then, we haven't carried out forecasting experiments, but we have once updated the list as noted above.

Below is the current list with suggestions up to March 2022. It has a simple categorization, as well as an occasional short summary which paraphrases or quotes key points from the posts linked. See the last appendix for some notes on nomenclature. If there are any entries I missed (and there will be), please say so in the comments and I'll add them. 

Initially, I created the "Cause Candidates" tag on the EA Forum and tagged all of the listed posts, and made available a Google Sheet. These are not maintained, but might be upon request.

Animal Welfare and Suffering

Pointer: This cause has its various EA Forum tags (farmed animal welfare, wild animal welfare, meat alternatives), where more cause candidates can be found. Brian Tomasik et al.'s Essays on Reducing Suffering are also a gift that keeps on giving for this and other cause areas.

1.Wild Animal Suffering Caused by Fires

Related categories: Politics: System change, targeted change, policy reform.

• Wild animal suffering caused by fires and ways to prevent it: a noncontroversial intervention (@Animal_Ethics)

An Animal Ethics grantee designed a protocol aimed at helping animals during and after fires. The protocol contains specific suggestions, but the path to turning these into policy is unclear.

2. Invertebrate Welfare

•  Invertebrate Welfare Cause Profile (@Jason Schukraft)
• The scale of direct human impact on invertebrates (@abrahamrowe)

"In this post, we apply the standard importance-neglectedness-tractability framework to invertebrate welfare to determine, as best we can, whether this is a cause area that is worth prioritizing. We conclude that it is."

Note: See also Brian Tomasik's Do Bugs Feel Pain.

3. Humane Pesticides

• Humane Pesticides as the Most Marginally Effective Cause (@JeffMJordan)
• Improving Pest Management for Wild Insect Welfare (@Wild_Animal_Initiative)

The post argues that insects experience consciousness, and that there are a lot of them, so we should give them significant moral weight (comments contain a discussion on this point). The post goes on to recommend subsidization of less-painful pesticides, an idea initially suggested by Brian Tomasik, who "estimates this intervention to cost one dollar per 250,000 less-painful deaths."  The second post goes into much more depth.

4. Diet Change

• Is promoting veganism neglected and if so what is the most effective way of promoting it? (@samuel072)
• Animal Equality showed that advocating for diet change works. But is it cost-effective? (@Peter_Hurford, @Marcus_A_Davis)
• Cost-effectiveness analysis of a program promoting a vegan diet (@nadavb, @sella, @GidonKadosh, @MorHanany)
• Measuring Change in Diet for Animal Advocacy (@Jacob_Peacock)

The first post is a stub. The second post looks at a reasonably high-powered study on individual outreach. It concludes that, based on reasonable assumptions, the particular intervention used (showing videos of the daily life of factory-farmed pigs) isn't competitive with other interventions on humans:

“(...) we now think there is sufficient evidence to establish that individual outreach may work to produce positive change for nonhuman animals. However, evidence in this study points to an estimate of $310 per pig year saved (90% interval: $46 to $1100), which is worse than human-focused interventions even from a species neutral perspective. More analysis would be needed to see how individual outreach compares to other interventions in animal advocacy or in other cause areas.

Given that a person can be reached for ~$2 and that they spare ~1 pig week, that works out to $150 per pig saved (90% interval: $23 to $560) and, again assuming that each pig has a ~6 month lifespan, that works out to $310 per pig year saved (90% interval: $47 to $1100). To put this in context, Against Malaria Foundation can avert a year of human suffering from malaria for $39, this does not look very cost-effective.”

Comments point out that the postulated retention rates may be too high (making the intervention even worse). Lastly, the second post was written in 2018, and more work might have been done in the meantime. 

The third post is somewhat more recent (Nov 2020), but it reports results in terms of "portions of meat not consumed" rather than “animal-years spared”. This makes a comparison with previous research not be straightforward, because different animals correspond to different intensity and length of suffering per kilogram of meat produced, and the post does not report how big these portions are or to which animals they belong. 

The fourth post explores "current and developing alternatives to self-reporting of dietary data."

5. Vegan/Vegetarian Recidivism

• Veg*n recidivism seems important, tractable, and neglected (@xccf)

"But there's a big problem with vegan/vegetarian advocacy: most people who switch to vegan/vegetarian diets later switch back."

The post suggests paying more attention to the growth rate of the vegan/vegetarian movement. It also suggests some specific measures, like producing resources which make it easier for vegetarians/vegans to get all the nutrients they need in the absence of animal products.

6. Plant-Based Seafood

• Plant-Based Seafood: A Promising Intervention in Food Technology? - Charity Entrepreneurship Approach Report (vicky_cox)

This Charity Entrepreneurship report ultimately concludes that: "...while fish product creation in Asia is the most promising intervention within food technology in terms of impact on animals, it is not the most promising intervention for Charity Entrepreneurship to focus on."

Note: Charity Entrepreneurship has produced many more reports. But, as they are not tagged on the EA Forum, they were difficult to incorporate in this analysis, given the search method I was using (see Appendix: Method). They are, however, available on their webpage.

7. Improving plant-based diets

• The Case for Rare Chinese Tofus (@George Stiffman)

In order to improve vegan alternatives, this post proposes to create new types of plant-based food crossing rare Chinese tofu with traditional western cooking methods. The author analyzes the idea in detail, and answers possible objections.

8. Moral Circle Expansion

• Why I prioritize moral circle expansion over artificial intelligence alignment (@Jacy_Reese)

"This blog post makes the case for focusing on quality risks over population risks. More specifically, though also more tentatively, it makes the case for focusing on reducing quality risk through moral circle expansion (MCE), the strategy of impacting the far future through increasing humanity's concern for sentient beings who currently receive little consideration (i.e. widening our moral circle so it includes them.)"

In particular, the post makes this point by comparing moral circle expansion to AI alignment as a cause area.

9. Analgesics for Farm Animals

Related categories: Politics: System change, targeted change, policy reform.

• Analgesics for farm animals (@Monica)

"There is only one FDA approved drug for farm animal pain in the U.S. (and that drug is not approved for any of the painful body modifications that farm animals are subjected to), FDA approval might meaningfully increase the frequency with which these drugs actually used, and addressing this might be a tractable and effective way to improve farm animal welfare [...] Farm animals in the U.S. almost never get pain medication for acutely painful procedures such as castration, tail docking, beak trimming, fin cutting, abdominal surgery, and dehorning. What I was not aware of until this morning is that there is only one FDA approved medication for ANY farm animal analgesic, and that medication is specifically approved only for foot rot in cattle [...] In contrast, the EU, UK, and Canada have much higher standards for food residues in other domains (hormones, antibiotics, etc.) but have nevertheless approved several pain medication for several procedures in species of farm animals. As a result, these drugs are much more commonly used there."

10. Welfare of Specific Animals

Rethink Priorities has done research on the welfare of specific animals, and possible interventions to improve it. They produced a number of profiles, some of which I include here for illustration purposes, but without any claim to comprehensiveness. Thanks to Saulius for bringing my attention to this point. 

• Honey Bee Welfare: Managed Honey Bee Welfare: Problems and Potential Interventions (@Jason Schukraft)
• Baitfish: Fish used as live bait by recreational fishermen (@saulius)
• Fish Stocking: 35-150 billion fish are raised in captivity to be released into the wild every year (@saulius)
• Wild-caught Fish: Worse things happen at sea: The welfare of wild-caught fish (Alison Mood, fishcount.org.uk)
• Cleaner Fish: Cleaner Fish: A Neglected Issue Within A Neglected Issue (@Martine Klock Fleten). Despite poor evidence, the use of cleaner fish is common practice among salmon farmers to control sea lice, leading to their suffering and death. The post proposes to improve cleaner fish welfare, or to put an end to this practice.
• Rodents Fed to Snakes: Rodents farmed for pet snake food (@saulius)
• Mice and Rats: [Question] Are mice or rats (as pests) a potential area of animal welfare improvement? (@Louis_Dixon) This post hints that the suffering of mice and rats in cities might be a possible cause area. The answers give several clues about how to tackle the issue.
• Insect Farming: Insects raised for food and feed — global scale, practices, and policy (@abrahamrowe)
• Snail Farming: Snails used for human consumption: The case of meat and slime (@Daniela R. Waldhorn)
• Cochineals: Global cochineal production: scale, welfare concerns, and potential interventions (@abrahamrowe)
• Silkworms: Silk production: global scale and animal welfare issues (@abrahamrowe). The post examines if the suffering of silkworms used in silk production could be an area to be prioritized, but concludes that available resources “might be better spent in other areas, such as reducing the painfulness of pesticides, reducing the number of insects farmed for animal feed, and reducing the harms of cochineal farming”.
• Owned cats outdoors in Canada: Would a reduction in the number of owned cats outdoors in Canada and the US increase animal welfare? (@kcudding)
• Chickens: [Question] New EA cause area: Breeding really dumb chickens (@Sam Enright). This post poses some questions about the idea of “breeding chickens (and other farm animals) to be less intelligent as a way to reduce the suffering caused by factory farming”.
• Baboons: Urban wildlife in South Africa - Cape baboons (@ajmfisher). "The aim of this post is to catalogue existing methods for managing the population of Cape chacma baboons living in the Cape peninsula, with a focus on welfare impacts for the baboons."

11. Cell-Based Meat R&D

• The extreme cost-effectiveness of cell-based meat R&D (@Stijn)

Based on a Fermi estimate, the author concludes that "cell-based meat research and development is roughly 10 times more cost-effective than top recommended effective altruist animal charities."

12. Animal-Free Proteins

• Animal-free proteins: A bright outlook and a to-do list (BCG report) (@FGH)

“The report describes what needs to happen to get to 11%, and further to 22% of meat, seafood, eggs and dairy eaten globally every day. Current technology must be refined and scaled, and in some areas, step changes are needed. For instance, optimized protein crops for human consumption need to be bred, and microorganisms as well as animal cells grown on low-cost feedstocks. Regulatory support, such as carbon taxes on meat or subsidies for farmers who are shifting from animal agriculture to alternative proteins, could further boost growth.”

13. Antibiotic Resistance in Farmed Animals

• Antibiotic resistance: Should animal advocates intervene? (@Bella_Forristal)

“Reducing antibiotic use in farms is very likely to be net positive for humans. However, it is not clear whether it would be net positive for animals. If farmers stop using antibiotics, animals might suffer from more disease and worse welfare. This effect might be mitigated by the fact that (i) farmers can replace antibiotics with substitutes such as probiotics, prebiotics, and essential oils, which also prevent disease, and (ii) farmers might be motivated to make adaptations to farming practices which prevent disease and also benefit animal welfare, such as lowering stocking density, reducing stress, and monitoring disease more closely. It is not obvious how likely it is that farmers will take these disease-mitigating measures, but since high disease rates increase mortality, decrease carcass profitability, and could cause reputational damage, it is plausible that they will be motivated to do so. Alternatively, animal advocates could take the 'holistic strategy' of promoting welfare measures which also tend to cause reduced antibiotic use. Tentatively, I take the view that eliminating antibiotic use on a farm would not lead to worse lives for those animals.

Eliminating antibiotics might also be expensive for producers, and because of this, it could increase the price of animal products in the short term, which would be good for animals. The literature weakly supports the view that meat prices will increase following an antibiotic ban. However, there is also some support for the view that price will increase differentially for smaller and larger animals, which lands us with the small animal replacement problem. This problem could be avoided by the approach taken to the intervention, e.g. a corporate campaign targeting only small animals.”

14. Helping Wild Animals Through Vaccination

• Helping wild animals through vaccination: could this happen for coronaviruses like SARS-CoV-2? (@Animal_Ethics)

"We will first see some cases of successful vaccination programs in the past, including vaccination against rabies, anthrax, rinderpest, brucellosis, and sylvatic plague, in addition to the proposal to vaccinate great apes against Ebola. Next, we will see how zoonotic epidemics have been the object of growing attention.We will then see some responses to them that are misguided and harmful to animals. We will then see the prospects for eventual wild animal vaccination programs against coronaviruses like SARS-CoV-2. We will see the three main limitations of such hypothetical programs. These are the lack of an effective vaccine, the lack of funding to implement the vaccination program, and the lack of an effective system to administer the vaccine. We’ll consider the extent to which these limitations could be overcome and what clues previous examples of vaccination can provide. As we will see, such programs remain to date merely speculative. They could be feasible at some point as other wild animal vaccination programs show. However, it remains uncertain whether there will be human interest in implementing them, despite the benefits for animals themselves.

Finally, we will see the reasons why, if implemented, programs of this kind could substantially help not just the vaccinated animals, but many others as well. Not only would this prevent zoonotic disease transmission to other animals, but such measures could also help inform other efforts to vaccinate animals living in the wild. Moreover, each successful vaccination program helps to illustrate that helping animals in the wild is not impractical, but realistic. This helps to raise concern for these animals and to inspire action on their behalf.”

15. Herbivorizing Predators

• Should we herbivorize predators? (@Stijn)

This post puts forth a moral argument with the intention to open discussion about considering herbivorizing predators as a cause area. The author argues that we should start doing scientific research to look for new technologies that would make it possible.

Community Building

1.Effective Animal Advocacy Movement Building

Related categories: Animal Welfare and Suffering

• Effective animal advocacy movement building: a neglected opportunity? (@Jamie_Harris)

The post argues that EAA-specific movement-building might be particularly neglected within EA.

2. Non-Western EA

• Neglected EA Regions (@DavidNash)

The post asks about expanding EA beyond the USA and Europe. It gets some pushback in the comments, particularly because of the difficulty of transmitting ideas with high fidelity.

3. Understanding and/or reducing value drift.

Pointer: This cause has its own EA Forum tag. 

• A Qualitative Analysis of Value Drift in EA (@MarisaJurczyk)

4. High School Outreach

• EA outreach to high school competitors (@Nikola)

“Specifically targeting STEM, logic, debate, and philosophy competitors with short outreach could increase high school outreach effectiveness as it would select for high-performing students who are more likely to engage with EA ideas. This would give these individuals more time to think about career choice and enable them to start building flexible career capital early and might make them more open to engaging with EA in the future.”

5. Idea Inoculation

• Effective outreach: evaluating "Idea innoculation" (@rsturrock)

This post proposes an experiment to serve as the basis of a psychology paper about EA ‘idea inoculation’, in order to discover better ways of conveying EA-related information.

6. Values Spreading

• Values Spreading is Often More Important than Extinction Risk (Brian Tomasik)
• On Values Spreading (@MichaelDickens)
• Against moral advocacy (Paul Christiano)
• Effective Altruism and Free Riding (@sbehmer)
• High-Leverage Values Spreading (@MichaelDickens)
• Promoting Simple Altruism (@LiaH)

Values spreading refers to improving other people's values. The idea has met with some skepticisim, but perhaps variants of it, like highly targetted or high-leverage values spreading, could still be promising.

Transhumanism

Related categories: Global Health and Development, States of Consciousness

1.Cryonics

• Is there a hedonistic utilitarian case for Cryonics? (Discuss) (@OzzieGooen)

Cryonics will probably get cheaper if more people sign up. It might also divert money from wealthy people who would otherwise spend it on more selfish things. Further, cryonics might help people take long-term risks more seriously. 

"One advantage of life extension is that it might prompt people to think in a more long-term-focused way, which might be nice for solving coordination problems and x-risks." 

One could also argue "that cryonics doesn't create many additional QALYs because by revival time we've probably hit Malthusian limits. So any revived cryonics patients would be traded off against other future lives."

• Brain preservation to prevent involuntary death: a possible cause area (@AndyMcKenzie)

The author argues that brain preservation is “one of the best areas for people interested in helping others to work in” and “a great place for people who are interested in helping others to donate money”.

2. Ageing

Pointer: This cause candidate has its own EA Forum tag. For illustration purposes:

• How to evaluate neglectedness and tractability of ageing research (@Emanuele_Ascani)
• Project Proposal: Gears and Aging (@johnswentworth)
• [Draft] Fighting Aging as an Effective Altruism Cause (@turchin)
• Cost-Effectiveness of Aging Research (@SarahC)
• A general framework for evaluating ageing research (@Emanuele_Ascani)
• RP Work Trial Output: How to Prioritize Anti-Aging Prioritization - A Light Investigation (@Linch)

3. Genetic Enhancement

• Genetic Enhancement as a Cause Area (@Galton)

The post makes the argument both from a short and long-term perspective. I was particularly intrigued by the suggestion to select for empathy; the comments also suggest selecting against malevolent traits.

4. Mind Enhancement

• Mind Enhancement: A High Impact, High Neglect Cause Area? (@timfarkas)

“This post aims to raise awareness, provide a rough framework for classification and list the most important theoretical arguments and considerations regarding the impact/desirability of mind enhancement.”

• Cause profile: Cognitive Enhancement Research (@George Altman)

“This post is a first attempt at analysing cognitive enhancement research using the ITN framework and cost-effectiveness estimates. Several interventions enhance cognitive functions such as intelligence and decision making. If we identify effective, cheap and scalable cognitive enhancement interventions, they may be competitive with GiveWell charities.”

Note: Post is a stub.

Politics: Global politics

Pointer: See also the EA Forum tag for Global Governance.

1. Democracy Promotion

• Democracy Promotion as an EA Cause Area (@bryanschonfeld)

The author estimates the benefits of democracy. They then suggest concrete actions to take: "a review essay on the efficacy of tools of external democracy promotion finds that non-coercive tools like foreign aid that is conditioned on democratic reforms and election monitoring are effective, while coercive tools like sanctions and military intervention are ineffective... One tool EA organizations can fund is election monitoring. Research suggests that election monitoring can play a causal role in decreasing fraud and manipulation." Some forum comments suggest that the area is too costly, and not that neglected.

• Decreasing populism and improving democracy, evidence-based policy, and rationality (@Hauke Hillebrandt)

This post explores several funding opportunities in this area. The author lists the following causes:

• Increasing rationality: Rationality could be increased by funding books as Galef’s The Scout Mindset, or projects as the Winton Centre for Risk and Evidence.
• General education spending: “[E]ducation can often predict populism better than income. Thus one funding idea might be to try to increase education budgets globally.”
• Civic education: “[C]ivic education can strengthen democratic beliefs and explain the relevance of pluralism, which can play an important role in preventing populist attitudes.”
• Journalism: Funding ideas include payments for online news content, the provision of local and investigative journalism, and investigative fact-check websites in general.
• Information spreading: “One way to reduce populism is to give activists the tools to expose and debunk populist 'common sense' arguments”, tools like Our World in Data.
• Research on populism: “Funding opportunity: Fund an academic researcher working on populism.”
• English language education: “Fostering English language learning improves access to more content. This might improve international relations.” But the author notes that learning English doesn’t seem neglected.
• Elections and voting: Funding opportunities include switching back to paper ballots to increase trust (Verified Voting Foundation), voting system reform, and the uses of statistical techniques to test election results, among others.
• Combatting computational propaganda: Several funding opportunities and ideas are proposed here to counterbalance current AI techniques spreading misleading information.
• Fostering more independent commissions and monitoring: Following the example of the Independent Commission for Aid Impact, which scrutinises UK aid spending, institutional decision making could be improved by setting up independent commissions for every major department in government.
• Aggregating expert consensus: “Aggregating expert consensus might decrease populism by reducing the faith put in common sense approaches.”
• Prediction markets: “Furthering the use of prediction market might help increase the accuracy of forecasts for important policy issues.”
• Doing more fundamental research: Funding could foster fundamental research, which is useful to find new techniques to improve institutional decision making.

2. Promotion of Parliamentarism

• The effective altruist case for parliamentarism (@Tiago Santos)

The author applies the ITN framework to promotion of parliamentarism and concludes that it is a valuable cause for EAs to focus on.

3. Promotion of Self-Determination

• A framework for self-determination (@kbog)

This post discusses the advantages of promoting more recognition of a right to self-determination. It develops a set of criteria to be met and applies them to the particular cases of Artsakh, Taiwan, and Crimea. Finally it shows some possible ways to reinforce the idea of self-determination.

4. Human Rights in North Korea

• Cause Area: Human Rights in North Korea (@Denis Drescher)

The scale of suffering seems vast, and marginal interventions (e.g., smuggling North Koreans out of China) might be cost-effective. The post also suggests capacity building in this area might be a promising intervention.

5. Improving Local Governance in Fragile States

• Improving local governance in fragile states - practical lessons from the field(@Timothy_Liptrot)

Politics: System Change, Targeted Change, and Policy Reform.

Note: These categories are grouped together because in practice the distinction between broad system change from outside a political system and targeted change or policy reform within a system is often not quite clear.

Pointer: This cause candidate has a related EA Forum tag: Policy Change.

1. Better Political Systems and Policy-Making

Pointer: The related Institutional Decision-Making has its own EA Forum tag; more cause candidates can be found there.

2. Getting Money Out of Politics and Into Charity

• Getting money out of politics and into charity (@UnexpectedValues)

Donors from two opposing parties could be matched to send their money to their favourite charities instead than to zero-sum political contests.

3. Vote Pairing

• Vote Pairing is a Cost-Effective Political Intervention (@Ben_West)

The post makes the case that vote pairing —where one or more voters for a mainstream candidate in a safe US state vote for a third-party candidate in exchange for a vote from a third candidate supporter in a contested state— is much more effective than other traditional interventions.

4. Electoral Reform

Pointer: This cause has its own EA Forum tag. I’m adding one post for illustration purposes:

• Why You Should Invest In Upgrading Democracy And Give To The Center For Election Science (@aaronhamlin)

Note: Included here for completeness. This isn't, strictly speaking, a new cause area because the Center For Election Science is working on it.

5. Tax Justice

• Tax Havens and the case for Tax Justice (@--alex--)

The post gives an overview of current efforts to make tax evasion or tax flight harder, and why this should be thought of as positive. A commenter, Larks, makes the opposite case.

6. Effective Informational Lobbying

• Informational Lobbying: Theory and Effectiveness (@Matt_Lerner)
• Effective Lobbying Discussion Group (@Noah Wescombe)

The first post starts with a literature review and concludes by proposing "something along the lines of ‘effective lobbying’: a rigorous approach to institutional-level change, starting with the legislature, that would take a portfolio approach to policy advocacy," and outlines how that would broadly look.

The second post is a "call to all interested in lobbying as both a career and an EA methods topic." Having a discussion group on this topic seems like a great idea, so I gave the post a strong upvote. However, it seems like it didn't get picked up when it was posted in mid-December 2020.

7. Ballot Initiatives

• Intervention Profile: Ballot Initiatives (@Jason Schukraft)

"The goal of this post is to bring ballot initiatives to the collective attention of the EA community to help promote future research into the effectiveness of ballot initiative campaigns for EA-aligned policies and movement-building." The post gives examples of what might be accomplished with ballot initiatives and covers their advantages and disadvantages.

10. Decline or Collapse of the US. 

• EA and the Possible Decline of the US: Very Rough Thoughts (@Cullen_OKeefe)

There are reasons to believe that the probability of regime collapse of the US in the next 50 years is higher than 0.5%. The dis-utility from Collapse could be extreme in certain scenarios.

Politics: Armed Conflict

This cause has two related EA Forum tags: Armed conflict and Nuclear Weapons which may contain more cause candidates.

Note: Luisa Rodríguez has more content in this cause.

2. Ukraine Conflict

• Ukraine giving - short term high leverage (@Timothy_Liptrot)

This post proposes supporting Ukraine as a cause area, arguing that if Russia is not strongly punished, other states could follow similar policies. The author goes on to propose buying satellites for improving Ukraine’s military system.

Global Health and Development

Pointer: This cause candidate has its own EA Forum tag.

1. Reducing the Efficiency of Genocides

Related categories: Politics

• A brief look at reducing the efficiency of genocides (@NLHeath)

The post makes the case that at least some genocides (the Rwandan, Myanmar, and possibly the Somalian genocides) could have been stopped with better oversight and targeted use of resources.

2. Malnutrition

• Might targeting malnutrition (not undernourishment!) be an important cause area? (@peter_janicki)

The author asks about the impact of malnutrition, i.e., "eating the wrong things as a voluntary choice despite having alternatives." This would mostly be a problem for middle and high-income countries.

3. Diet Change

• Dietary habits – Another potential Cause Area? (@peter_janicki) 

Unhealthy food choices result in poor diets that reduce expected lifespan and life quality. The author of this post collects a considerable amount of evidence and argues that this a neglected area, given the number of people affected by those choices.

4. Raising IQ

Related categories: Transhumanism

• Consider raising IQ to do good (@Lila_Rieber)

"Interventions to raise IQ could do a lot of good because of potentially significant flow-through effects of intelligence. IQ also has the benefit of being easily quantifiable, which would make it simpler to compare interventions."

Note: In practice, the raising-IQ framing is unpalatable for some people, as are some charities in an adjacent space, like Project Prevention. However, because one of the most effective ways of raising IQ is reducing malnourishment or undernourishment, and in particular, iodine deficiency, one could focus on these causes instead. Note that mal/undernourishment in kids leads to lower wages in adulthood. Although one might suspect IQ is the mediating factor, it's not necessary to emphasize the connection.

5. Physical Goods

• The EA movement is neglecting physical goods (@ruthgrace)

"Seven out of eight of the Givewell top charities deal with physical goods—anti-malaria nets, deworming medication, and vitamins. But otherwise, there's not much discussion/active work in EA on how to improve/spin up the physical manufacture and distribution of physical goods beyond donating money to existing organisations."

6. Fighting Diarrhoea

• How does fighting diarrhoea stack up to malaria in effectiveness? (@MichaelDello)

Diarrhoea seems like a large problem because more people die of it per year (or did so in 2015). The remedy is apparently "oral rehydration therapy: a large pinch of salt and a fistful of sugar dissolved in a jug of clean water."

Note: GiveWell has moved slowly and cautiously on this topic, but Evidence Action's Dispensers for Safe Water program is now a GiveWell Standout charity.

7. Fighting Fistulae

• [Question] Can it be more cost-effective to prevent than to treat obstetric fistulas? (@brb243)

The author suggests a way of preventing fistulas which may be much cheaper than surgery: “targeting midwives to share information on when to seek specialized care and identify at-risk patients, training doctors at government (free of charge) clinics, providing equipment, and potentially offering travel stipend to extremely poor households”.

8. International Supply Chain Accountability

Related categories: Politics: System change, targeted change, policy reform.

• New Cause Area Proposal: International Supply Chain Accountability (@NunoSempere)

Workers' organizations can lobby international companies to adopt better labour conditions across their supply chain, and to get the original companies to pay for these efforts. A particularly promising strategy is to apply pressure in the countries these companies originate from (Spain, Germany, the US), rather than in the countries where the products are made. This seems to be working for the case of Inditex (Zara, and various other textile brands). It is unclear how, and if, EA might get organizations working in this area to accept external funds, but they could in principle absorb a lot of them.

Note: I'm the author of this post.

9. Chloramphenicol for Heart Attacks

• Chloramphenicol as intervention in heart attacks (@G Gordon Worley III)

The article linked suggests approving Chloramphenicol as a coronary treatment, which is claimed to be a fixed cost of "$25 million spent once to save 400,000 lives per year in the U.S. alone." Comments point out that the estimate "seems to be based on one study of 21 pigs."

10. COVID-19

Pointer: This cause candidate has its own EA Forum tag, which contains more cause candidates. Here are some examples included for illustration purposes:

• Is rapid diagnostic testing (RDT), such as for coronavirus, a neglected area in Global Health? (@Ramiro)
• Customized COVID-19 risk analysis as a high value area (@Askell)
• Responding to COVID-19 in India (@Suvita)

• Coronavirus and long term policy [UK focus] (@weeatquince)

11. Vaccines

• EA Should Spend Its “Funding Overhang” on Curing Infectious Diseases (@joshcmorrison) 

The author argues that “funding overhang” should be spent developing vaccines against infectious diseases:

“If EA’s investing $10 billion in vaccination over the next ten years could save the equivalent of 3-5 years of disease burden of a disease like tuberculosis, it would represent a cost per disability-adjusted-life-year (DALY) saved of roughly $50-$85 (on par with GiveWell top charities).”

12. Clean Cookstoves

• Clean cookstoves may be competitive with GiveWell-recommended charities (@Suvita)

This is a very quick, rough model of the cost-effectiveness of promoting clean cookstoves in the developing world. It suggests that:

"If a clean cookstove intervention is successful, it may have roughly the same ballpark of cost-effectiveness as a GiveWell-recommended charity.

Circa 90% of the impact comes from directly saving lives, based on a model which estimated both the number of lives saved and the impact on climate change."

13. Agricultural R&D

• Agricultural research and development (@David_Goll)

“In combination, the difficulties with estimating the effects of R&D and the potential barriers to adoption suggest that the estimated benefit-cost ratios reported earlier are likely to be upwardly biased. The benefit-cost ratios estimated are also lower than those associated with Giving What We Can’s currently recommended charities. For instance, the $304 per QALY estimate based on the Copenhagen Consensus benefit-cost ratio, which appears to be at the higher end of the literature, compares unfavourably to GiveWell’s baseline estimate of $45 to $115 per DALY for insecticide treated bednets (GiveWell, 2013). The benefit-cost ratios also appear to be lower than those associated with micronutrient supplements, as discussed earlier. While there are significant benefits that remain unquantified within agricultural R&D, the same is also true for interventions based on bednet distribution, deworming and micronutrient supplements. As a result, while this area could yield individual high impact opportunities, the literature as it stands does not seem to support the claim that agricultural R&D is likely to be more effective than the best other interventions.”

14. Golden Rice

• Should GMOs (e.g. golden rice) be a cause area? (@mariushobbhahn)

“In this post, I want to very roughly ​​evaluate whether golden rice should be of interest to EAs and whether genetically modified organisms (GMOs) in general are worth investigating deeper.”

The author concludes that this cause is valuable, though acknowledges that golden rice wouldn't allow to reach levels of efficiency comparable to GiveWell top charities. 

15. Agricultural Land Redistribution

• Intervention report: Agricultural land redistribution (@David Rhys Bernard & @Jason Schukraft)

The authors conclude that advocating for agricultural land redistribution is neither tractable nor cost-effective.

16. Ventilation

• Cost-Effectiveness of Air Purifiers against Pollution (@Lukas Trötzmüller)

"The goal for this post is to give an introduction into the human health effects of air pollution, encourage further discussion, and evaluate an intervention: The use of air purifiers in homes. These air purifiers are inexpensive, standalone devices not requiring any special installation procedure. A first analysis suggests that the cost-effectiveness of this intervention is two orders of magnitude worse than the best EA interventions. However, it is still good enough to qualify as an ’effective’ or even ‘highly effective’ health intervention according to WHO criteria."

• How a ventilation revolution could help mitigate the impacts of air pollution and airborne pathogens (@Mike Cassidy) 

Indoor air pollution can be worse than outdoor pollution, yet it is neglected. Installing ventilation and filtration systems in our buildings would reduce economic losses arising from air pollution and respiratory viruses.

17. Stubble Burning in India

• Stubble Burning in India (@Jason Schukraft)

Stubble burning in north India is a major contributor to seasonal decreases in ambient air quality [...] Stubble burning releases carbon dioxide, carbon monoxide, nitrogen oxides, sulfur oxides, and methane as well as particulate matters (PM₁₀and PM_2.5) (Abdurrahman, Chaki, & Saini 2020). These pollutants affect the immediate area and also drift southeast to Delhi, smothering the city of ~22 million in thick haze. At their peak, these fires are responsible for ~58% of Delhi air pollution (Beig et al. 2020). The consequences of this air pollution include skin and eye irritation, respiratory problems (dry cough, wheezing, breathlessness, chest discomfort, asthma), and hypertension (Rizwan, Nongkynrih, & Gupta 2013). Air pollution is estimated to be responsible for at least 48,000 premature deaths in Delhi alone in 2020 (Greenpeace, n.d.).^[5] Nationwide, the open burning of agricultural residue is estimated to be responsible for more than 66,000 premature deaths in India (GBD MAPS Working Group 2018).^[6]

18. Starvation in Afghanistan

• [Linkpost] Millions face starvation in Afghanistan (@aogara)

Since the Taliban seized power, US sanctions and the sudden suspension of foreign aid worsened the situation in Afghanistan to the extent that millions of people are at risk of starvation and death.

19. Water, Sanitation and Hygiene Interventions

• If you (mostly) believe in worms, what should you think about WASH? (@alexrjl)

According to GiveWell's research, the overwhelming majority of the value of mass deworming interventions (DW) comes from expected long-term economic effects rather than short-term effects on health. The mechanism by which these long-term effects occur is unclear, especially as the health effects are so small.

The best WASH interventions (in particular, Dispensers for Safe Water, but possibly also Development Media International) have larger health effects than DW.

If the long-term effects of deworming are related to the health effects of worms, it is likely that the long-term economic effects of WASH interventions are at least as good. If the effects are somehow specific to worms, given that a significant part of the benefit of WASH is in preventing parasitic worm infestation, there should still be significant long-term effects of WASH interventions.

20. Research on Inbreeding

• Inbreeding and global health & development (@pafnuty) 

“Inbreeding (also known as consanguinity) is associated with an increased risk of adverse prenatal outcomes including stillbirths, low birth weight, preterm delivery, abortion, infant and child mortality, congenital birth defects, cognitive impairments, malformations and many other complex disorders. . . . [R]esearch on this issue in the context of global health and development is scarce, and additional research might generate ample information value about potentially impactful interventions.”

21. Stopping Miscarriages

• Might stopping miscarriages be a very important cause area? (@SaraAzubuike) 

The author implies that stopping miscarriages could be important (if there’s some probability that embryos are human), given that miscarriages occur in 20% of pregnancies.

22. Advocacy for Legalizing Abortion

• [Question] Developing countries and adolescent pregnancy: how effective could advocacy for legalizing abortion be? (@Ramiro) 

Adolescent pregnancy is associated with high rates of child mortality. The author advances that advocacy for legalizing abortion may be an effective way to prevent this tragedy in developing countries.

23. Drug Legalisation

• Ending The War on Drugs - A New Cause For Effective Altruists? (@MichaelPlant)

Moving from drug prohibition to legalisation would be beneficial to drug users (decriminalisation) and drug-producing and trafficking countries (less violence). The author raises the question of whether this could be an area to be prioritized.

24. Patent Policy

• Global Health Innovation Incentives, Patent Trolls, and Evergreening: Discussion of Subtopics within US Patent Policy (@schethik)

This post covers three candidates within patent policy: The first is global health innovation incentives:

“Alternative innovation finance mechanisms—such as advanced market commitments and the Health Impact Fund—can help incentivize firms to invest in R&D aimed at helping developing countries’ poorest people. The present patent system, on the other hand, provides limited incentive to create innovations for these people.”

The second candidate is patent trolling: Some firms' merely buy patents and sue others for infringing on their rights, without really producing anything themselves. These patent trolls cost money to other firms, which therefore turn hesitant to use technology, and unwilling to innovate.  

“However, many legislative and judicial steps have been taken since 2013 to address patent trolling in the US, making the issue—in our view—presently low in scale, neglectedness, and tractability.”

The third is evergreening,  which doesn't seem to be a high priority either: 

“It does not appear that companies unfairly extend (i.e., evergreen) their patent terms using statutory strategies. However, there is reason to believe companies use other means such as the 30-month stay provision to extend effective market monopolies.”

The author also recommends further research into this area.

25. Training Economists

• Hits-based development: funding developing-country economists (@Michael_Wiebe)

“One specific mechanism [for promoting growth] is to train developing-country economists, who then work in government and influence policy in a pro-growth direction, ultimately increasing the probability of a growth episode.”

26. Improving Welfare Algorithms

• [Link] Improving the lives of millions of Latin Americans through better welfare targeting algorithms (@NORIEGA)

“More than 50 million people in Latin America are impacted by the decision of very simple linear algorithms which determine how much welfare they receive from social programs. Simple changes to the algorithm lead to hundreds of thousands of people being added or removed to major welfare programs.”

The author holds that improving these algorithms would allocate billions of dollars more effectively.

27. Low Back Pain

• Preventing low back pain with exercise (@Ryan Kidd)

This post argues that exercise seems to be the most effective treatment to prevent low back pain, which is a symptom experienced by people of all ages and socioeconomic circumstances. A comment by Aaron suggests that this might be a solid cause area in the developing world.

28. Chronic Pain

• Should Chronic Pain be a cause area? (@mariushobbhahn) 

This post gives an overview of what chronic pain is, and its relation with demographic and environmental factors. It finally discusses whether it could be a worthy cause area, reaching no conclusion.

29. Intactivism

• Intactivism as a potential Effective Altruist cause area? (@Question Mark) 

The author argues against the practice of circumcision and proposes its abolition.

30. Delaying Aging

• Work Test for Charity Entrepreneurship: Delaying Aging (@Heye Groß)

This post argues that aging is the most common cause of death and human suffering. There are already known effective interventions (exercise, fighting smoking) against accelerated aging. For this reason, research confirming that aging itself is responsible for aging-related diseases could yield many cost-effective programs.

31. Health in Younger Generations

This post is an excerpt from this piece by Peter Harrigan. It calls attention to the idea that price risk is one of the more overlooked sources of poverty. Third world farmers face constant risk from price volatility, which reduces their profits and leads them to bankruptcy.

34. Fighting Corruption

• Fighting corruption in aid-embezzling (@MarcSerna)

This post estimates that aid-embezzling in developing countries could cut “from 10% to 50% of donations received by charitable organizations in humanitarian and development settings”. It proposes the creation of an organization dedicated to do audits of development and humanitarian projects in such countries.

35. Lead Exposure

Global Health and Development: Mental Health

Related categories: States of consciousness.

Pointer: This cause candidate has two related EA Forum tags: Mental Health (Cause Area) and Subjective Well-Being. For illustration purposes:

• Cause profile: mental health (@MichaelPlant)

"Not only does mental illness seem to cause as much, if not more, total worldwide unhappiness than global poverty, it also seems far more neglected. Effective mental health interventions exist currently. These have been improving over time and we can expect further improvements. I estimate the cost-effectiveness of a particular mental health organisation, StrongMinds, and claim it is (at least)four times more effective per dollar than GiveDirectly, a GiveWell recommended top charity. This assumes we understand cost-effectiveness in terms of happiness, as measured by self-reported life satisfaction [...] Even if mental health is a large-scale, neglected problem, we shouldn't consider it a possible moral priority if there aren't effective treatments. Fortunately, there are."

• HLI's Mental Health Programme Evaluation Project - Update on the First Round of Evaluation (@Jasper Synowski)

The project, which seems to be ongoing, tries to systematically assess a long list of mental health interventions.

Initially, various EAs proposed varied experimental mental health interventions. There are a number of posts asking if "mental health issue X" should fall within Effective Altruism's purview. Of these, mental health apps represent probably the most well-argued intervention and stand on a class of their own. In particular, they are scalable.

• "Fixing Adolescence" as a Cause Area? (@kirchner.jan) 

Adolescence comes frequently with substantial suffering. After analyzing abundant data, and pointing out the lack of strategies to tackle this problem, the author suggests that more research is desirable to establish this as a cause area.

Advances in LED technology enable lighting solutions that emit vastly more light than traditional light boxes. Here, we assess the feasibility of BROAD (Bright, whole-ROom, All-Day) light therapy and get a first estimate for its potential effectiveness.”

• Sex work as part of mental health and wellbeing services (@Mary) 

This post argues that instead of trying to discourage sex workers, there is a number of reasons for which “it is worth considering integrating this profession more into society”:

“Sex workers satisfy a very essential need, providing not only sexual intercourse but also company, a listening ear, a safe space where is no judgment. Otherwise dangerous paraphilias can be safely practiced, believed to be shameful wants can be satisfied, never said fantasies can be discussed. Victims of sexual abuse, people with mental health conditions, couples with sexual problems can not only talk or discuss their problems, as it would be possible in a clinical setting but can also receive practical help too. All of these attributes make sex work a potentially valuable addition to mental health and wellbeing services.”

Related categories: Global Health and Development. Politics: System change, targeted change, policy reform.

• Increasing Access to Pain Relief in Developing Countries - An EA Perspective (@Lee_Sharkey)

Access to opioids is unduly restricted, such that the pain of some deaths can amount to "torture by omission". The author suggests, as a tentative donation target, the Pain and Policy Studies Group of the University of Wisconsin-Madison which "runs 'International Pain Policy Fellowships', which train national champions of the cause to identify and overcome barriers to the use of opioids in their countries. The programme has had numerous in-country successes." However, the program seems to now be defunct. One organization that I personally perceive as promising, which is working in this space, is The Organisation for the Prevention of Intense Suffering.

4. Cluster Headaches

• OPIS initiative on access to psilocybin for cluster headaches (@jonleighton)

"Cluster headaches are considered one of the most excruciating conditions known to medicine..."; "there is [...] evidence that psilocybin mushrooms can prevent and abort entire episodes. Such evidence has been published as survey data and is also widely reported by patients in cluster headache groups. TwoPhase I RCTs are ongoing and should add to the existing evidence for efficacy. Lack of access to psilocybin mushrooms and widespread information about using them are key barriers to effective treatment for many patients."

• Hedonium (Less Wrong tag page)
• Wireheading (Less Wrong tag page)

Compressing as much happiness into a unit of matter can be pursued at all levels of technological development. With current technology, we could have animal farms dedicated to making rats, about which we know a fair bit, maximally happy. With future technology, we could have computer simulations of maximal bliss. 

The idea is sometimes thought to be morally repugnant or philosophically misguided, and a quick Fermi estimate suggests that current happy animal farms would not be cost effective compared to interventions in the developing world.

1. Space Colonization

• What analysis has been done of space colonization as a cause area? (@reallyeli)
• The Case for Space: A Longtermist Alternative to Existential Threat Reduction (@Giga)
• An Informal Review of Space Exploration (@kbog)

If we had a backup planet, existential risk would be reduced. Further, we'd be able to have more people. However, even with a backup planet, existential risk in both planets would be correlated, and the protection from extinction that the second planet provides would be inversely proportional to the degree of correlation. One might expect this correlation to be particularly high for hostile AI. See here for some discussion on these points.

User @kbog looked at this issue in more depth, and concluded that:

In this post I take a serious and critical look at the value of space travel. Overall, I find that the value of space exploration is dubious at this time, and it is not worth supporting as a cause area, though Effective Altruists may still want to pay attention to the issue. I also produce specific recommendations for how space organizations can rebalance their operations to have a better impact.

2. Space Governance

• Space governance is important, tractable and neglected (@Tobias_Baumann)

"I argue that space governance has been overlooked as a potentially promising cause area for longtermist effective altruists. While many uncertainties remain, there is a reasonably strong case that such work is important, time-sensitive, tractable and neglected, and should therefore be part of the longtermist EA portfolio [...] The work I have in mind aims to replace the current state of ambiguity with a coherent framework of (long-term) space governance that ensures good outcomes if and when large-scale space colonisation becomes feasible."

2. Philosophy in Schools

"Much greenhouse gas emissions comes from uncontrolled underground coal fires. I can't find any detailed source on its share of global CO2 emissions; I see estimates for both 0.3% and 3% quoted for coal seam fires just in China, which is perhaps the world's worst offender. Another rudimentary calculation said 2-3% of global CO2 emissions comes from coal fires. They also seem to have pretty bad local health and economic effects, even compared to coal burning in a power plant (it's totally unfiltered, though it's usually diffuse in rural areas). There are some methods available now and on the horizon to try and put the fires out, and some have been practiced - see the Wikipedia article. However, the continued presence of so many of these fires indicates a major problem to be solved with new techniques and/or funding for the use of existing techniques."

13. Improving Disaster Shelters to Increase the Chances of Recovery From a Global Catastrophe

Pointer: This cause candidate has its own EA Forum tag.

• Improving disaster shelters to increase the chances of recovery from a global catastrophe (@Nick_Beckstead)

“What is the problem? Civilization might not recover from some possible global catastrophes. Conceivably, people with access to disaster shelters or other refuges may be more likely to survive and help civilization recover. However, existing disaster shelters (sometimes built to ensure continuity of government operations and sometimes built to protect individuals), people working on submarines, largely uncontacted peoples, and people living in very remote locations may serve this function to some extent.

What are the possible interventions? Other interventions may also increase the chances that humanity would recover from a global catastrophe, but this review focuses on disaster shelters. Proposed methods of improving disaster shelter networks include stocking shelters with appropriately trained people and resources that would enable them to rebuild civilization in case of a near-extinction event, keeping some shelters constantly full of people, increasing food reserves, and building more shelters. A philanthropist could pay to improve existing shelter networks in the above ways, or they could advocate for private shelter builders or governments to make some of the improvements listed above.”

15. Exploring Using Insights from International Relations Theory to facilitate International Cooperation Against Existential Risks 

• International Cooperation Against Existential Risks: Insights from International Relations Theory (@Jenny_Xiao)

Dealing with existential risks requires international cooperation. Naturally, one might expect scholars of international relations (IR) to provide the best answers regarding how states can cooperate to protect humanity’s long-term potential. Yet reading Tody Ord’s new book The Precipice as a PhD student in IR, I am surprised how little attention my field has paid to the existential threats Toby raised in the book, such as global disease, climate change, and risks from artificial intelligence (AI). 

Although mainstream IR often overlooks existential risks, it does offer insight into how to make international cooperation easier. In particular, IR theory’s emphasis on the importance of national interests offers us a realistic view of international behavior. Isaac Asimov, a universalist and humanist, once dismissed decisions based on the national interest as “emotional” reactions on “such nineteenth century matters as national security and local pride.” My view is exactly the opposite: We should work with states as they are, not what we wish them to be.

“First, the international effort to track near-Earth asteroids is potentially humanity’s most successful effort to date to directly address an existential risk. . . . Second, expanding beyond mere detection to building deflection systems probably shouldn’t be a priority right now — not just because other comparably tractable risks look far more urgent, but because deflection technology could pose risks of its own from malign use.”

26. Biosecurity

• Project Ideas in Biosecurity for EAs (@Davidmanheim)

“In conjunction with a group of other EA biosecurity folk, I helped brainstorm a set of projects which seem useful, and which require various backgrounds but which, as far as we know, aren't being done, or could use additional work. Many EAs have expressed interest in doing something substantive related to research in bio, but are unsure where to start - this is intended as one pathway to do so.”

• State of the land: Misinformation and its effects on global catastrophic risks (@ruthgrace)

Basing on experience from the last pandemic, this post highlights the danger posed by misinformation to future global biological catastrophic risks on the rise, and sketches some possible ways to do something about it.

• Non-pharmaceutical interventions in pandemic preparedness and response (@James Smith)

The author argues that evaluation of non-pharmaceutical interventions (e.g. mask wearing, hand-washing, social distancing, etc.) is neglected and that the scale of its impact could be high.

• Concrete Biosecurity Projects (some of which could be big) (@ASB & @eca)

This post gives a list of longtermist biosecurity projects. The first is about improving response time to biothreats by early detection. This could happen by setting up an Early Detection Center where a small team collects “samples from volunteer travelers around the world and then does a full metagenomic scan”.

The second project points out that most personal protective equipment (PPE)—e.g. masks, suits, etc.—has a number of disadvantages. Materials science and product design could produce better PPE than our current options, i.e. “highly effective in extreme cases, easy to use, reliable over long periods of time, and cheap/abundant”.

The third proposes better medical countermeasures against biothreats “either by 1) producing targeted countermeasures against particularly concerning threats (or broad-spectrum countermeasures against a class of threats), or by 2) creating rapid response platforms that are reliable even against deliberate adversaries”.

The fourth points out some possible ways of strengthening the Biological Weapons Convention. The fifth recommends further investigation on the advantages of sterilization technologies “that rely on physical principles (e.g. ionizing radiation) or broadly antiseptic properties (e.g., hydrogen peroxide, bleach) rather than molecular details (e.g. gram-negative antibiotics)”.

The last project is to create pandemic-proof refuges:

“Existing bunkers provide a fair amount of protection, but we think there could be room for specially designed refuges that safeguard against catastrophic pandemics (e.g. cycling teams of people in and out with extensive pathogen agnostic testing, adding a ‘civilization-reboot package’, and possibly even having the capability to develop and deploy biological countermeasures from the protected space).”

Rationality and Epistemics

• Long-term investment fund at Founders Pledge (@SjirH)

3. Improving our Estimate of the Philanthropic Discount Rate

• Estimating the Philanthropic Discount Rate (@MichaelDickens)

How we should spend our philanthropic resources over time depends on how much we discount the future. A higher discount rate means we should spend more now; a lower discount rate tells us to spend less now and more later.

According to a simple model, improving our estimate of the discount rate might be the top effective altruist priority.

The post is structured in a confusing way, but a core suggestion is to tweak various current AI systems, particularly the Youtube and Facebook algorithms, to better fit EA values. However, the post doesn't give specific suggestions of the sort a Youtube engineer could implement.

4. Positively Shaping the Development of Crypto-Assets

• An Argument To Prioritize Positively Shaping the Development of Crypto-assets (@rhys_lindmark)

The article tries to analyze the promisingness of influencing the development of crypto assets from an ITN perspective, in 2018. Three of its most notable points are:

1. Effective Altruists should shape the implementation of any high-impact new technology,
2. crypto-assets constitute a new organizational technology which could solve a bunch of coordination problems, and
3. the use of crypto assets could result in beneficial resource redistribution.

• A Democratic Currency (@MikkW) 

The author outlines the creation of a new (digital) currency with a view to tackle poverty:

“[T]he major source of the currency will be in the people as a whole, with a certain fixed percentage of the value represented by the currency (that is, the market cap), being credited, on regular intervals (for example, every day), to every single person known to the currency.”

• The transformative potential of cryptocurrencies (@bejaq) 

The author argues that decentralized creation of money (instead of money creation by central banks) could lead to better ways of distributing money.

• Cause Area: UK Housing Policy (@GMcGowan)

The author gives an overview of the problem and presents the solution advocated by the YIMBI movement in the UK, namely a political reform reducing veto power and giving households on a street the means of allowing development by a majority vote. The concluding section lists a number of reasons for and against EA involvement in this area.

• Vetocracy reduction and other coordination problems as potential cause areas (@John_Myers)

This post examines the problem posed by veto players when majorities are trying to bring forward development. Improving coordination techniques could be the way to break such deadlock not only here, but also in many other areas:

“With high uncertainty, I think that focusing a small amount of resources on improving broader coordination techniques for reducing such large deadweight losses in various areas could be a highly impactful, tractable and neglected area of research.”

Note: This cause area comprises two distinct areas: giving by companies, and giving by employees.

Note: Corporate Social Responsability has the potential to be used by companies to cheaply distract from their pretty terrible working conditions in their supply chains by having ineffective corporate giving strategies which donate to recipients in the developed world. Last time I checked (two years ago). See International Supply Chain Accountability.

Appendix I: Method

I queried all forum posts using the following query at the EA forum's GraphQL API:

{
posts(input: {
terms: {
meta: null  # this seems to get both meta and non-meta posts
after: "10-1-2000"
before: "10-11-2020" # or some date in the future
}
}) {
results {
title
url
pageUrl
postedAt
}
}
}

Then, I copied them over to a document called last5000posts.txt.

The EA forum API returns a maximum of 5000 entries, but this is not a problem because it currently only has 4077 posts. 

I then searched for the keywords "cause x", "cause y", "new cause", "cause", "area", "neglected", "promising", "proposal", "intervention", "effectiveness", "cost-effective", using grep, a Unix/Linux tool, taking care to use the case-insensitive option (this is necessary because, although links contain the title in lowercase, links don't always contain the full title). An example of using grep to do this is: 

grep -i "cause x" last5000posts.txt >> searchoutputs.txt

which appends the results to the searchoutputs.txt file if the file exists, and otherwise creates that file. 

I then looked through the posts with the “Cause-Prioritization” tag and under the most upvoted posts to see if I had missed anything. I then went through all EA Forum tags which had some relation to cause candidates and read through the relevant posts.

When I started tagging the posts I'd found, I found out about the "Less-discussed Causes" tag. I didn't like its categorization scheme, which also included things other than cause candidates, so I continued creating my own tags. The “Less-discussed Causes'' tag had about 5 posts I wouldn't have found. I also found many more posts which were not in the tag. 

I imagine a similar method could be used to efficiently populate other tags.

Appendix II: A Note on Nomenclature

Trivia: See Soviet Nomenklatura.

Thanks to Michael Aird for pushing for clarification of the terms I'm using, and for asking exactly what this list was about.

Terms:

• Cause Area: A broad category of causes. For example, "animal welfare and suffering" would be a cause area, "factory-farmed animals" and "wild animal welfare" would be slightly less-broad cause areas.
• Cause: Something more specific than a cause area. For example, "analgesics for farm animals" would be a cause within the "factory-farmed animals" cause area.
• Intervention, charity idea, etc.: Something more specific than a cause. For example, a ballot initiative to provide more space for factory-farmed animals, like 2018 California Proposition 12 would be an intervention. "Working to bring approval voting to Saint Louis" would be an intervention within the cause "better voting methods", itself within the cause area "better political systems".
• Meta-intervention: An intervention that can be applied to different causes. For example, ballot initiatives.

Question: On what level of specificity am I working in this post?

In practice, it's often hard to establish whether something is a cause area, a cause, or an intervention. For example, I'd say that "climate change" is a cause area and that "extinguishing or preventing coal seam fires" is a cause, but the original post refers to it as a cause area.

Column C —"Level of specificity"— this google sheet contains information about the categorization chosen for each cause candidate (from intervention to cause area).
