[Warning: long comment] Thanks for the pushback. I think converting to lives is good in other cases, especially if it’s (a) useful for judging effectiveness, and (b) not used as a misleading rhetorical device [1].
The basic point I want to make is that all interventions have to pencil out. When donating, we are trying to maximize the good we create, not decide which superficially sounds better between the different strategies “empower beneficiaries to invest in their communities’ infrastructure” and “use RCTs to choose lifesaving interventions” [2]. Lives are at stake, and I don’t think those lives are less important simply because it’s harder to put names and faces to the ~60 lives that were saved from a 0.04% chance of reduction of malaria deaths from a malaria net. Of course this applies equally to the Wytham Abbey purchase or anything else. But to point (a), we actually can compare the welfare gain from 61 lives saved to the economic security produced by this project. GiveWell has weights for doubling of consumption, partly based on interviews from Africans [3]. With other projects, this might be intractable due to entirely different cause areas or different moral preferences e.g. longtermism.
Imagine that we have a cost-effectiveness analysis made by a person with knowledge of local conditions and local moral preferences, domain expertise in East African agricultural markets, and the quantitative expertise of GiveWell analysts. If it comes out that one intervention is 5 or 10 times better than the other, as is very common, we need a very compelling reason why some consideration was missed to justify funding the other one. Compare this to our currently almost complete state of ignorance as to the value of building this plant, and you see the value of numbers. We might not get a CEA this good, but we should get close as we have all the pieces.
As to point (b), I am largely pro making these comparisons in most cases just to remind people of the value of our resources. But I feel like the Wytham and HPMOR cases, depending on phrasing, could exploit peoples’ tendency to think of projects that save lives in emotionally salient ways as better than projects that save lives via less direct methods. It will always sound bad to say that intervention A is funded rather than saving X lives, and we should generally not shut down discussion of A by creating indignation. This kind of misleading rhetoric is not at all my intention; we all understand that allowing a large enough number of farmers access to sorghum markets can produce more welfare than preventing 61 deaths from malaria. We have the choice between saving 61 of someones’ sons and daughters, and allowing X extremely poor people to perhaps buy metal roofs, send their children to school, and generally have some chance of escaping a millennia-long poverty trap. We should think: “I really want to know how large X is”.
[1] and maybe (c) not bad for your mental health?
[2] Unless you believe empowering people is inherently better regardless of the relative cost, which I strongly disagree with.
[3] This is important—Westerners may be biased here because we place different values on life compared to doubling consumption. But these interviews were from Kenya and Ghana, so maybe Uganda’s weights slightly differ.
@Thomas Kwa in my eyes this is a hugely insightful (perhaps even spectacular) response, thanks for taking the time to think about it and write it. Perhaps consder writing a full post with these kinds of insights about benefits of CEAs.
That is If you can stomach spending more time away from your real job making sure that we still exist in 50 years to even talk about GHD ;).
