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.
re: your lady example: as far as I know, the recent papers e.g. here provide the following example: (1) either you help the old lady on a Monday or on a Tuesday (you must and can do exactly one of the two options). In this case, your examples for CC1 and CC2 don't hold. One might argue that the previous example was maybe just a mistake and I find it very hard to come up with CC1 and CC2 for (1) if (supposedly) you don't know anything about Mondays or Tuesdays.
