Andreas Mogensen, a Senior Research Fellow at the Global Priorities Institute, has just published a draft of a paper on "Maximal Cluelessness". Abstract:
I argue that many of the priority rankings that have been proposed by effective altruists seem to be in tension with apparently reasonable assumptions about the rational pursuit of our aims in the face of uncertainty. The particular issue on which I focus arises from recognition of the overwhelming importance and inscrutability of the indirect effects of our actions, conjoined with the plausibility of a permissive decision principle governing cases of deep uncertainty, known as the maximality rule. I conclude that we lack a compelling decision theory that is consistent with a long-termist perspective and does not downplay the depth of our uncertainty while supporting orthodox effective altruist conclusions about cause prioritization.
As I say in another comment, I think that a few effects - such as reducing the risk of human extinction - can be rescued from cluelessness. Therefore, I'm not committed to being indifferent between literally all actions.
I do, however, think that consequentialism provides a reason for only very few actions. In particular, I do not think there is a valid argument for donating to AMF instead of the Make-a-Wish Foundation based on consequentialism alone.
This is actually one example of where I believe cluelessness has practical import. Here is a related thing I wrote a few months ago in another discussion:
"Another not super well-formed claim:
- Donating 10% of one's income to GiveWell charities, prioritizing to reduce chicken consumption over reducing beef consumption, and similar 'individual' actions by EAs that at first glance seem optimized for effectiveness are valuable almost entirely for their 'symbolic' and indirect benefits such as signalling and maintaining community norms.
- Therefore, they are analogous to things like: environmentalists refusing to fly or reducing the waste produced by their household; activists participating in a protest; party members attending weekly meetings of their party; religious people donating money for missionary purposes or building temples.
- Rash criticism of such actions in other communities that appeals to their direct short-term consequences is generally unjustified, and based on a misunderstanding of the role of such actions both within EA and in other communities. If we wanted to assess the 'effectiveness' of these other movements, the crucial question to ask (ignoring higher-level questions such as cause prioritization) about, say, an environmentalist insisting to always switch of the lights when they leave a room, would not be how much CO2 emissions are avoided; instead, the relevant questions would be things like: How does promoting a norm of switching off lights affect that community's ability to attract followers and other resources? How does promoting a norm of switching off lights affect that community's actions in high-stakes situations, in particular when there is strategic interdependence -- for example, what does it imply about the psychology and ability to make credible commitments of a Green party leader negotiating a coalition government?
- It is not at all obvious that promoting norms that are ostensibly about maximizing the effectiveness of all individual 'altruistic' decisions is an optimal or even net positive choice for maximizing a community's total impact. (Both because of and independently of cluelessness.) I think there are relatively good reasons to believe that several EA norms of that kind actually have been impact-increasing innovations, but this is a claim about a messy empirical question, not a tautology."
