I mostly disagree with both parts of the sentence “Except that it’s much cheaper to convince other people’s kids to be generous, and our influence on the adult behavior of our children is not that big.” I would argue that
(1) Almost all new EA recruits are converted in college by friends and/or by reading a very small number of writers (e.g. Singer). This is something that cannot be replicated by most adults, who are bad writers and who are not friends with college students. We still need good data on the ability of typical humans to covert others to EA ideas, but my anecdotal observations (e.g. Matt Wage) suggest that this is MUCH harder than you might think.
(2) Despite one’s acceptance of genetic fatalism, it’s known that the biggest influences a parent can have are the religious and political associations of their children. Insofar as donating is determined more by affiliating with the EA movement than by bio-determined factors like IQ, we can expect parents to strongly induce giving by their children.
We can look to evangelical religions to get an idea of what movement building techniques are most effective for the bulk of the population. Yes, many religions have missionaries, but this is usually a small group of unusually motivated and charismatic people. But having lots of children is a strategy that many religions have effectively employed for the bulk of their members.
(One potential counter example I’d be interested to hear about is the effectiveness of the essentially compulsory missionary work for Mormon men.)
Hmm. I haven’t spent much time in the area, but I went to the Cambridge, MA LessWrong/Rationality “MegaMeetup” and it was almost exclusively students. Is there a Boston EA community substantially disjoint from this LW/Rationality group that you’re talking about?
More generally, are there many historical examples of movements that experience rapid growth on college campuses but then were able to grow strongly elsewhere? Civil rights and animal welfare are candidates, but I think they mostly fail this test for different reasons.
I honestly do not think this is possible, and again I look to religious organizations as examples where (my impression is that) finding effective missionaries is much harder than getting the minimal funding they need to operate at near-maximum efficiency. This is something we need more data on, but I expect a lot of the rosy pictures people have of translating money or other fungibles into EA converts will not stand up to scrutiny, in much the same way that GiveWell has raised by an order of magnitude its estimates of the cost of saving a life in the developing world. I especially think that the initial enthusiasm of new EAers converted through repeatable methods (like 80k hours) will fade more quickly in time than “organic” converts and children raised in EA households (to an even greater extent than for religions).
Maybe. I have the impression that religions most used missionaries to expand geographically, and hit diminishing returns very quickly once they had a foothold. Basically, I guess that as soon as a potential convert knows the organization exists, you’ve essentially already hit the wall of diminishing returns. I agree as long as EA stuff has non-structural geographic lumpiness (i.e. geographic concentrations that are a result of accidents of history rather than for intrinsic reasons related to where EA memes are most effective) then EA missionary work may be the major driver of growth. But I think the EA memes are most effective on a wealthy, technologically connected sub-population which we may quickly saturate in just a few years.
I hear many more people describe their own conversion experience as something akin to “I heard the argument, and it just immediately clicked” (even if personal inertia prevented them making immediate drastic changes). I do not hear many people describe it as “I had heard about these ideas a few times, but it was only when Bob [who was supported by EA funding] took the time to sit and talk with me for a few hours that I was convinced.” (Again, that’s just anecdotal.)
Can we look at the history of the Catholic church during times when new populations of potential converts became accessible through exploration/colonization? What fraction of the church’s resources went to missionary work, and did the church reduce its emphasis on having children so that parents would have more free money to give to the church?
Incidentally, these kind of questions are what make me wish we had more EA historians. We could use a lot more data and systematic analysis.
