But tractability is not a binary (tractable vs. intractable). Rather, we should expect tractability to vary continuously, especially as low-hanging fruit is picked (ie. we get diminishing marginal returns as funding is directed to an intervention). So the ‘best cause’ will change over time as funding changes.
