A flowchart like that seems like a good idea to me. I did briefly mention the possibility of some sort of flowchart in my post, although on reflection I actually think it could be even better than I first gave it credit. It can align people to the cause areas that fit their underlying views, whilst also countering potential misunderstandings that prevent people doing more good than they otherwise would. For example, in reality many people with person-affecting views might reject longtermism off the bat, but that global priorities project flowchart would guide those people, if they still care about people in the far future (like Arjun in my original post), to longtermist areas that may be robust to certain person-affecting views. I like that!
I would endorse a refresh of that flowchart, but think it would be helpful to have underlying content that people can look at if they want to understand the logic of the flowchart or make better decisions as they go along the flowchart. “Can we permanently improve society” is a pretty darned tough question for someone to answer, so it would be good to have some helpful easy-to-digest content for those who may want to read up on that a bit before actually giving an answer. It’s quite a different question to “Are future people just as valuable as present people” which seems more subjective, although even for this question there could be some useful content to link to.
I may have a bit more of a think about a list of questions. Thanks for raising it!
(I believe an EA wiki type thing is currently in the works, so these sorts of efforts could perhaps be combined with that somehow.)
