I was wondering if someone here has a better idea of how EA developed in its early days than I do.
Judging by the link I posted, it seems like Yudkowsky used the term “effective altruist” years before Will MacAskill or Peter Singer adopted it. The link doesn’t mention this explicitly, but Will MacAskill was also a lesswrong user, so it seems at least plausible that Yudkowsky is the true father of the movement.
I want to sort this out because I’ve noticed that a recently lot of EAs have been downplaying the AI and longtermist elements within the movement and talking more about Peter Singer as the movement’s founder. By contrast the impression I get about EA’s founding based on what I know is that EA started with Yudkowsky and then MacAskill, with Peter Singer only getting involved later. Is my impression mistaken?
EA as a movement was a combination of a few different groups (This account says Giving what we can/80000 hours, Givewell, and yudkowsky’s MIRI). However, the main source of early influx of people was the rationalist movement, as Yud had heavily promoted EA-style ideas in the sequences.
So if you look at surveys, right now a a relatively small percentage (like 15%) of EA’s first heard about it through lesswrong or SSC. But back in 2014, and earlier, Lesswrong was the number one onroad into the movement (like 30%) . (I’m sure a bunch of the other answers may have heard about it from rationalist friends as well). I think it would have been even more if you go back earlier.
Nowadays, most of the recruiting is independent from the rationalists, so you have a bunch of people coming in and being like, what’s with all the weird shit? However they still adopt a ton of rationalist ideas and language, and the EA forum is run by the same people as Lesswrong. It leads to some tension: someone wrote a post saying that “yudkowsky is frequently confidently, egregiousl wrong”, and it was somewhat upvoted on EA forum but massively downvoted on Lesswrong.
