They don't care about overhead, they will recommend a charity that prevents a death per $5'000 and has a 50% overhead over a charity that prevents a death per $10'000 and has a 20% overhead.
I’m very familiar with them, yes. They definitely care about overhead
> We quantify impact using a variety of different measures, including "cost per life saved" (when applicable) and "financial benefits to recipients per dollar spent by donors" (when applicable).
I don't understand how that is a meaningful definition of overhead. Overhead is money that is not being spent on salaries and goods that directly impact outcomes. Therefore cheaper outcomes always imply lower overhead.
