Comments on Jacy Reese Anthis' Some Early History of EA (archived version). Summary: The piece could give the reader the impression that Jacy, Felicifia and THINK played a comparably important role to the Oxford community, Will, and Toby, which is not the case. I'll follow the chronological structure of Jacy's post, focusing first on 2008-2012, then 2012-2021. Finally, I'll discuss "founders" of EA, and sum up. 2008-2012 Jacy says that EA started as the confluence of four proto-communities: 1) SingInst/rationality, 2) Givewell/OpenPhil, 3) Felicifia, and 4) GWWC/80k (or the broader Oxford community). He also gives honorable mentions to randomistas and other Peter Singer fans. Great - so far I agree. What is important to note, however, is the contributions that these various groups made. For the first decade of EA, most key community institutions of EA came from (4) - the Oxford community, including GWWC, 80k, and CEA, and secondly from (2), although Givewell seems to me to have been more of a grantmaking entity than a community hub. Although the rationality community provided many key ideas and introduced many key individuals to EA, the institutions that it ran, such as CFAR, were mostly oriented toward its own "rationality" community.  Finally, Felicifia is discussed at greatest length in the piece, and Jacy clearly has a special affinity to it, based on his history there, as do I. He goes as far as to describe the 2008-12 period as a history of "Felicifia and other proto-EA communities". Although I would love to take credit for the development of EA in this period, I consider Felicifia to have had the third- or fourth-largest role in "founding EA" of groups on this list. I understand its role as roughly analogous to the one currently played (in 2022) by the EA Forum, as compared to those of CEA and OpenPhil: it provides a loose social scaffolding that extends to parts of the world that lack any other EA organisation. It therefore provides some interesting ideas and leads to the discovery of some interesting people, but it is not where most of the work gets done.  Jacy largely discusses the Felicifia Forum as a key component, rather than the Felicifia group-blog. However, once again, this is not quite what I would focus on. I agree that the Forum contributed a useful social-networking function to EA. However, I suspect we will find that more of the important ideas originated on Seth Baum's Felicifia group-blog and more of the big contributors started there. Overall, I think the emphasis on the blog should be at least as great as that of the forum. 2012 onwards Jacy describes how he co-founded THINK in 2012 as the first student network explicitly focused on this emergent community. What he neglects to discuss at this time is that the GWWC and 80k Hours student networks already existed, focusing on effective giving and impactful careers. He also mentions that a forum post dated to 2014 discussed the naming of CEA but fails to note that the events described in the post occurred in 2011, culminating in the name "effective altruism" being selected for that community in December 2011. So steps had already been taken toward having an "EA" moniker and an EA organisation before THINK began. Co-founders of EA To wrap things up, let's get to the question of how this history connects to the "co-founding" of EA. > Some people including me have described themselves as “co-founders” of EA. I hesitate to use this term for anyone because this has been a diverse, diffuse convergence of many communities. However, I think insofar as anyone does speak of founders or founding members, it should be acknowledged that dozens of people worked full-time on EA community-building and research since before 2012, and very few ideas in EA have been the responsibility of one or even a small number of thinkers. We should be consistent in the recognition of these contributions. There may have been more, but only three people come to mind, who have described themselves as co-founders of EA: Will, Toby, and Jacy. For Will and Toby, this makes absolute sense: they were the main ringleaders of the main group (the Oxford community) that started EA, and they founded the main institutions there. The basis for considering Jacy among the founders, however, is that he was around in the early days (as were a couple of hundred others), and that he started one of the three main student groups - the latest, and least-important among them. In my view, it's not a reasonable claim to have made. Having said that, I agree that it is good to emphasise that as the "founders" of EA, Will and Toby only did a minority - perhaps 20% - of the actual work involved in founding it. Moreover, I think there is a related, interesting question: if Will and Toby had not founded EA, would it have happened otherwise? The groundswell of interest that Jacy describes suggests to me an affirmative answer: a large group of people were already becoming increasingly interested in areas relating to applied utilitarianism, and increasingly connected with one another, via GiveWell, academic utilitarian research, Felicifia, utilitarian Facebook groups, and other mechanisms. I lean toward thinking that something like an EA movement would have happened one way or another, although it's characteristics might have been different.
