Leaving aside tractability … neglectedness … and goodness … I wanted to argue for importance.
Neglectedness is an unusually legible metric and can massively increase marginal impact. So acute awareness of neglectedness when considering allocation of effort should solve most issues of failing to address every possible point of intervention. Assessment of tractability/goodness/importance gives different puzzles for every hypothetical intervention, and studying these puzzles can itself be a project. Neglectedness is more straightforward, it’s a lower-hanging strategic fruit, a reason not to skip assessing tractability/goodness/importance for things nobody is working on, to not dismiss them out of hand for that reason alone.
