In 2011 effective altruists in Oxford had two main organizations: Giving What We Can and 80,000 Hours. They wanted to incorporate, and created the Centre for Effective Altruism as an umbrella organization to host them: [1]
Over time they started running other projects: conferences, supporting local groups, the EA forum, community health, etc. There was effectively a "CEA" community-focused organization within the "CEA" umbrella organization:
This was pretty confusing: when someone said "CEA" did they mean the organization focused on the EA community ("CEA runs EA Global") or the umbrella organization ("80k is part of CEA")? This got even more confusing as there started to be more organizations and projects:
In September 2022 the umbrella organization renamed itself to the Effective Ventures Foundation:
Unfortunately the announcement wasn't very clear about what specifically was changing, and a lot of people are still confused about when to say "CEA" and when to say "EV". Hopefully this history and the diagrams clear things up a bit!
[EDIT: changed 'EVF' to 'EV'; Shakeel says they prefer the latter.]
[1] This is also the origin of using effective altruism to refer to the movement.
This is clarifying in the sense of "what is the internal structure of this organisation, and how did it come to be".
But I don't think it's relevant to most people's arguments/discussions/complaints regarding any of these "orgs". The reason is that there is just one org. Just one board making decisions. Any discussion of 80k is a discussion of EVF. Any complaint about CEA is a complaint about EVF. They're all interchangable in such contexts. "EVF bought Wytham Abbey" is the same thing as "CEA bought Wytham Abbey", because a literal interpretation of the latter is nonsensical, as CEA is not an actual organisation.
There are pros and cons to insisting on the "proper" names for these entities - on the one hand, preventing confusion; on the other hand, preventing the continuity of criticism aimed at them, and risking that new people who join thus have a hard time finding out about existing criticism.
'Soft influence' then, if they have a hands-off approach? Either way, it seems concerning.
