Effective altruism has had three main direct broad causes (global poverty, animal rights, and far future), for quite some time. I have often heard people worry that it’s too hard for a new cause to be accepted by the effective altruism movement. Simultaneously, I do not really see people presenting new cause areas in the way I think would be the most likely for many EAs to consider and take seriously. I wanted to make a quick reference post as a better way for people to propose new cause/intervention areas they might see as promising. Much of this advice could also be used to present a new specific charity within a known high impact cause area.
1) Be ready to put in some real time
2) Have a specific intervention within the broad cause to compare
3) Compare it to the most relevantly comparable top cause.
4) Compare it numerically
5) Focus on one change at a time
6) Use equal rigour
7) Have a summary at the top
1) Be ready to put in some time
Comparing different cause areas is hard and takes a good amount of research time. In the effective altruism movement there are many people and organizations who work full time comparing interventions within a single cause, and generally it's much harder to compare interventions across cause areas. Generally it's going to take some time to effectively articulate a new cause area, particularly if the EA movement has not spent much collective time considering it. It's not expected, or even possible, that one person does all the research required in a whole cause area, but if you think a cause area is competitive, you likely will have to be the first one to do some of the initial research and start to build a case for why others should consider it. To start to get enough reasoning for EAs to really consider a cause it has to start to stand out among the hundreds of other causes that could be high impact to work on.
2) Have a specific intervention within the broad cause to compare
As mentioned above, comparing whole cause areas is hard. In many ways it's also not the point. If cause area A is more effective than global poverty on average but all the specific interventions in it can not compete with the best global poverty charities (e.g., AMF), it will still not be a great target to put resources towards. Additionally, it's much harder to get into the details and comparisons of a whole cause area which will often contain numerous different interventions. The best way around these concerns I have seen is to drill down on an example of a highly promising intervention. For example, if you are making the case that mental health in the third world is a high impact cause area, look deeply into a specific example, like CBT cell phone applications. With a more specific intervention it will be easy to fact check as well as numerically compare it to the other top interventions EAs currently support.
3) Compare it to the most relevantly comparable top cause.
A huge number of causes that are brought up are not directly compared to the most relevant comparable cause area. If someone is making a case for positive psychology and mental health, the natural comparison is to the GiveWell top charities. If it's about wild animal suffering, it needs to be compared to farm animal interventions, and if it's about bio-risk, it could be compared to AI. If someone is sold on far future and pitching a new cause area within it, making generalized arguments about the far future being better than AMF is not going to do much work convincing people. Most EAs will have already heard AMF vs. AI comparison and those sorts of arguments will not be new or persuasive to AMF supporters and do nothing to compare the cause to its real competition, AI. Some cause areas might be amenable to multiple comparisons (bio risk could be made as a far future case compared to AI or a direct DALYs improved compared to AMF), but in any case, try to compare it to the cause that contains the sorts of people who are most likely to find your new proposed cause high impact.
4) Compare it numerically
Effective altruists are a quantitative bunch and numerical comparisons are basically necessary for seriously comparing the good done in different cause areas and interventions. There are a lot of different ways to do this, but a safe bet would be a cost-effectiveness analysis in a spreadsheet or guesstimate model. As mentioned above, depending on the most relevant cause you are comparing to, you will want to generally model things in that context. That would generally mean DALYs or cost per life saved for global poverty, animal DALYs for animals, or percent chance of affecting long term society for far future. Cross-comparing metrics is a useful blog post in and of itself, but it’s not going to be best presented while simultaneously presenting a new cause area. This leads well into my next point.
5) Focus on one change at a time
Often when people present new cause areas they come with a lot of other proposed changes. They could be ethical (e.g. we should have X view on population ethics), epistemic (e.g. we should value historical evidence more) or logistical (e.g. we should use this CEA software even though it’s harder to read for beginners). As mentioned above, all of these might be worthwhile changes for the EA movement to make, but if it’s conflated with a suggested cause, generally I have seen people dismiss the cause because of the other associated claims with it. For example, “Only negative leaning utilitarians think cause X is important, and I am not negative leaning.” This often happens with causes that have a very strong case even with fairly traditional EA standards of evidence/ethics etc. If the cause area as a whole relies on an ethical or other assumption to be competitive, I would generally recommend writing about that specifically before pitching a cause or intervention that is reliant on it.
6) Use equal rigour
Not only does a new cause need to be compared -- it ideally needs to be compared with equal rigour, at least as much as is possible. It's easy to point out flaws in one charity or cause area and only highlight the benefits of another, but without comparing them with the same level of rigour, the numbers will be useless next to each other. To use a clear example of this, I have seen bus ads that claim to save a life for $1 and yet I still donate to GW charities which claim to save a life for $3000. This is mainly because the way the calculation was done was completely different, even if they were both put into a dollar per life saved metric at the end. I expect that if the $1 charity was compared using GiveWell’s methodology, its cost-effectiveness would rapidly decrease. Likewise, if a cause area is presented with very optimistic estimates, it’s hard to take the endline conclusion seriously -- much like the bus ad.
This is an easy one to say but very hard to do in practice. The best way I have found is to try to think, “How would GiveWell (or ACE, etc) model this?”, and try to follow those principles. Another great way is to get an EA or two who you respect and is not sold on your cause area to take a look over your numbers and suggest changes. People will comment, suggesting changes on almost any model, but if it's too far off a realistic number, many people just will not bother with commenting on all the things that need changes. Lastly, another thing to keep in mind is that often logistical costs are easy to forget. X product may only cost $1,000 and save a life of DALYs, but what about shipping costs, staff overhead, government permissions, etc? Underestimating these often significant costs are a common reason why CEAs get worse as people investigate deeper.
7) Have a summary at the top of a more in depth review
Particularly for long posts, having a summary at the top with the strongest arguments and endline conclusions will make it a lot easier for people to know if they should commit to reading the whole post or not, as well as allow engagement from people who do not have time to dig into all the details of the full post.
Why bother pitching a new cause within EA?
Following all these steps is a lot of work and that energy and time could be being put into furthering the cause directly or earning money and donating to it. Despite this, I think in almost all cases it is worth presenting a new cause area to EA if it's possible it could be competitive. The EA community directs large portions of money both directly through earning to give and indirectly from influencing large foundations. Historically, very underfunded causes like AI x-risk and farm animal rights have both massively benefited from EA financial support. In addition, the EA movement directs talent towards high impact cause areas, new charities are founded, Ivy League graduates apply for jobs and volunteer research is done in areas that are seen as high impact. Even if a well written cause report takes 20 hours or more to do the benefits can be much larger if even a small percentage of the EA community is convinced the cause area is worthwhile.
I worry you've missed the most important part of the analysis. If we think what it means for a "new cause to be accepted by the effective altruism movement" that would proably be either:
It becomes a cause area touted by EA organisations like Give Well, CEA, or GWWC. In practice, this involves convincing the leadership of those organisations. If you want to get a new cause in via this route, that's end goal you need to achieve; writing good arguments is a means to that end.
you convince individuals EA to change what they do. To a large extent, this also depends on convincing EA-org leadership, because that's who people look to for confirmation a new cause has been vetted. This isn't necessarily stupid on the part of individual EAs to defer to expert judgement: they might think "Oh, well if so and so aren't convinced about X, there's probably a reason for it".
This seems as good as time as any to re-plug the stuff I've done. I think these mostly meet your criteria, but fail in some key ways.
I first posted about mental health and happiness 18 months ago and explained why poverty is less effective than most will think and mental health more effective. I think I was, at the time, lacking a particular charity recommendation though (I now think Basic Needs and Strong Minds look like reasonable picks); I agree it's important new cause suggestions have 'shovel ready' project.
I argued you, whoever you are, probably don't want to donate the Against Malaria Foundation. I explain it's probably a mistake for EAs to focus too much on 'saving lives' at the expense of either 'improving lives' or 'saving humanity'.
Back in August I explain why drug policy reform should be taken seriously as new cause. I agree that lacks a shovel ready project too, but, if anything, I think there was too much depth and rigour there. I'm still waiting for anyone to tell me where my EV calcs have gone wrong and drug policy reform wouldn't be more cost-effective than anything in GiveWell's repertoire.
The people at 80kh etc. probably have their hands full. Therefore, even though your post making the case for mental health was laudable, I can well imagine it might not result in action in the short term on their part because of heavy prioritization.
If one wants to make substantive case and roadmap for possible actions for MH, it might make sense to take the initiative and do it oneself or together with a group of interested people. Given there is enough credence for the case, this effort might lead to formation of a new EA-aligned MH organization. I for one, might be interested in helping out with making the case for MH
