Will MacAskill is seeking feedback on the 80,000 Hours advice page he's written for those who ask the question: "I want to make a difference. Should I become a philosopher?", with a full profile evaluating the PhD in Philosophy (from an "effective altruist" perspective) here.
It seems generally pretty accurate to me. The one thing that really jumped out to me is the mere middling score currently assigned for "job satisfaction". Will rightly stresses that it's incredibly difficult to secure a permanent job in philosophy (which I assume is reflected in its receiving the lowest possible score on "ease of competition"). But for those of us fortunate enough to make it, I really do think it's the best job in the world. I certainly can't imagine anything else I'd rather do, and I'm sure I'm not the only one. (See, e.g., the comments in this thread.)
I also think he may be underestimating the possible impact of teaching. Even if it's true that most philosophy students will eventually come across Singer's pond argument, etc., regardless of who their teachers are, I think it can make a difference how these things are taught -- whether it's approached as a merely intellectual puzzle, or in a more practically engaged way that really challenges us to reflect on our values and how to live in a way that's (more or less) consistent with those values. I suspect that having a supportive faculty member may make students more likely to set up a local Giving What We Can chapter, further spreading and normalizing "effective altruist" ideas. And there are often opportunities to speak to wider audiences -- for example, I just gave a couple of mini-lectures on this material for our recent University Open Days, and had multiple parents approach me afterwards to express their interest in learning more about effective charities, etc. Hard to know how much of an effect any of this has, of course, but it's at least encouraging. And none of this requires being a research superstar: it's stuff that any ethics lecturer can easily do.
So, that's my 2 cents. What do you think?
