Hell yes to all of this. I'll also add that as someone who grew up in a small town (not a universal experience but probably a shared one) I found mega-cities like New York or London to be so overwhelming in their scale that just trying to get around was stressful.
DC is, as Anon mentions, a pretty compact city, and young professionals tend to live in a small number of neighborhoods (Petworth, Shaw, Adams Morgan, Columbia Heights, Mt. Pleasant, H St — I'm probably dating myself with this list) that aren't far apart from each other. You can walk from the center of AdMo to the center of Petworth in about 40 minutes. I found that really helpful in getting used to living in a city in general, and getting good at living in a city is useful for doing impactful work.
Anyway, excited to see you all at EAG this month :)
These are all fair points. For myself, I'll say that (a) we have a lot of evidence internally that Vox's readership is pretty left-leaning and (b) I care a lot about persuading people of core EA ideas, like giving impartially and effectively, the importance of global poverty/animals/future people, etc. So naturally when I'm aiming to persuade, I tend to make arguments I think will make sense to the audience I know I have.
I didn't intend the piece to alienate EAs who don't have center-left politics, and apologize if I had that effect anyway. I agree that a strength of the movement is the relative lack of ideological litmus tests, and I hope that continues.
Perhaps helpful: a few years ago Hidden Brain did an episode on my marriage and how my wife (who is a lovely, ethical person, but doesn't identify as EA and has some significant disagreements with some EA ideas) and I (an EA trying his best who's also wrong sometimes) get along. Obviously we're just one couple so our discussions/tensions may not be representative, but I thought Shankar Vedantam and the producer, Rhaina Cohen, did a fantastic job.
I wonder how much of this is explained by utilitarians selecting out of professional philosophy because of the theory's implications.
I seriously considered philosophy grad school and was discouraged by some mentors who thought that if I took consequentialism seriously, other career options were more promising avenues to impact.
If enough people do that, though, the academy's going to be left leaning against consequentialism.
I don't know that I'm the kind of person OP is thinking of, but beyond opportunity cost there's also a question of reportorial distance/objectivity. I've thought a lot about whether to do a project like this and one sticking point is (a) I identify as an EA (b) I donate to GiveWell and signed the GWWC pledge (c) many of my friends are EAs, so I'm not sure any book I produce would be perceived as having sufficient credibility among non-EA readers.
