If there are so many new promising causes that EA should plausibly focus on (from something like 5 to something like 10 or 20), cause-prio between these causes (and ideas for related but distinct causes) should be especially valuable as well. I think Will agrees with this—after all his post is based on exactly this kind of work! - but the emphasis in this post seemed to be that EA should invest more into these new cause areas rather than investigate further which of them are the most promising—and which aren’t that promising after all. It would be surprising if we couldn’t still learn much more about their expected impact.
