Really interesting way to start looking at this idea. I have been wanting to think about this topic for a while but it’s such a large question — using ChatGPT seems like a good way to get a foothold.
Some other organisations that I think have lessons for EA are the 20th century “service groups” like Rotary International, Lions Club etc. Particularly Rotary has some similarities (local groups, international network) and some successes in ambitious projects (eradicating polio). Under the categories you put forward, I think this would be categorised under social movement support but perhaps also network development by influencing people who end up holding power.
It’s not clear to me what’s most useful about doing these comparisons — maybe we can see certain outcomes we want to avoid, or learn about ways that the initial philosophy of the organisation changes over the lifespan. I also think there are some interesting observations about what gives an organisation a long lifespan or do these movements primarily confine themselves to people of a single generation.
I think that this question framed as an all-or-nothing is difficult to answer—we don’t know how to measure all the benefits as well as risks that the current community patterns afford us. Plus we can’t exactly change “EA” as a whole—but we could add subcomponents that have tighter centralisation, official membership etc.
This could be a great undertaking as a “spin-off” brand that collaborates closely with existing EA community groups. There are some follow-on questions that come to mind like:
would the target members be primarily working in high-impact roles or would they be in other professions and have an interest in EA? (Less educational perks can be offered if the member base is from different industries)
is there a segment of people who would join the professional association and be a part of that community that wouldn’t be otherwise interested in EA? (Maybe other philanthropy-focused professionals)
(Cons of a spin-off approach come to mind, namely confusing org structures)
