I’d like to point to the essay Multiplicative Factors in Games and Cause Prioritization as a relevant resource for the question of how we should apportion the community’s resources across (longtermist and neartermist) causes:
TL;DR: If the impacts of two causes add together, it might make sense to heavily prioritize the one with the higher expected value per dollar. If they multiply, on the other hand, it makes sense to more evenly distribute effort across the causes. I think that many causes in the effective altruism sphere interact more multiplicatively than additive, implying that it’s important to heavily support multiple causes, not just to focus on the most appealing one.
