Effective altruism (EA) requires that when we donate to charity, we maximize the beneficial impact of our donations. While we are in broad sympathy with EA, we raise a practical problem for EA, which is that there is a crucial empirical presupposition implicit in its charity assessment methods which is false in many contexts. This is the presupposition that the magnitude of the benefits (or harms) generated by some charity vary continuously in the scale of the intervention performed. We characterize (...) a wide class of cases where this assumption fails, and then draw out the normative implications of this fact. (shrink)

Effective altruism has a strategy problem. Overreliance on a strategy of donating to the most effective charities keeps us on the firefighter's treadmill, continually pursuing the next-highest quantifiable marginal gain. But on its own, this is politically shortsighted. Without any long-term framework within which these individual rescues fit together to bring about the greatest overall impact, we are almost certainly leaving a lot of value on the table. Thus, effective altruists' preferred means undercut their professed aims. Alongside the charity framework, (...) the more effective altruist ought to consider a mutual aid framework, which better acknowledges and honors the unavoidably political commitments of effective altruism to reimagine and remake the world.
