I've mostly thought of crucial considerations (CCs) in the longtermist domain. It's not surprising that if you're trying to improve welfare impartially over space and time, there will be a lot of CCs. But suppose you're focusing on the near term (including / especially animal welfare). I'm curious to hear which CCs people working on near-term philanthropy have found to be especially important. Just listing them, with relevant links if necessary, would be great. Thanks!
(Some examples that have occurred to me: displacement effects, the poor meat eater problem, maybe wacky anthropics stuff? I'm also aware of the CCs tag on the Forum.)
in a thread there i mentioned that even for a described 'ultimate neartermist', the best action is actually to cause acausal trade (i.e. by causing aligned ASI) with an ASI at an earlier point in time. for a hypothetical value which only cares about near-term beings, this would also be true, because most near-term beings are not on earth.
also, if i consider a hypothetical value which just cares about near-term beings on earth, it may prefer to destroy earth instead of slowly reducing animal suffering. 'would want to destroy earth' is a classical response to the idea of pure negative utilitarianism, but it would apply to standard utilitarianism too if the things valued (in this hypothetical case, just near-term beings on earth) experienced more bad than good which could not be mitigated enough in the near-term.
(disclaimer: the 'neartermism' of actual humans is probably importantly different to these, probably more reliant on moral intuition than these literal interpretations. i'm a longtermist myself.)
