We should put all possible changes/reforms in a big list, that everyone can upvote/downvote, agree disagree.
EA is governed but a set of core EAs, so if you want change, I suggest that giving them less to read and a strong signal of community consensus is good.
The top-level comments should be a short clear explanation of a possible change. If you want to comment on a change, do it as a reply to the top level comment
This other post gives a set of reforms, but they are a in a big long list at the bottom. Instead we can have a list that changes by our opinions! https://forum.effectivealtruism.org/posts/54vAiSFkYszTWWWv4/doing-ea-better-1
Note that I do not agree with all comments I post here.
[epistemic status: my imprecise summaries of previous attempts]
Well, I guess it depends on what you want to get out of them. I think they can be useful as epistemic tools in the right situation: They tend to work better if they are focused on empirical questions, and they can be help by forcing the collaborators to narrow down broad statements like "democratic decision making is good/bad for organisations". It's probably unrealistic however to expect that the collaborators will change their minds completely and arrive at a shared conclusion.
They might also be good for building community trust. My instinct is that it would be really helpful in the current situation if the two sides see that their arguments are being engaged with reasonably by the other side. (see this ac on transgender children transitioning, nobody in the comments expresses anger at the author holding opposite views)
