Oliver: … Thus we see that donating to the opera is the best way of promoting the arts.
Eleanor: Okay, but I’m principally interested in improving human welfare.
Oliver: Oh! Well I think it is also the case that donating to the opera is best for improving human welfare too.
Generally, what is best for one thing is usually not the best for something else, and thus Oliver’s claim that donations to opera are best for the arts and human welfare is surprising. We may suspect bias: that Oliver’s claim that the Opera is best for the human welfare is primarily motivated by his enthusiasm for opera and desire to find reasons in favour, rather than a cooler, more objective search for what is really best for human welfare.
The rest of this essay tries to better establish what is going on (and going wrong) in cases like this. It is in three parts: the first looks at the ‘statistics’ of convergence – in what circumstances is it surprising to find one object judged best by the lights of two different considerations? The second looks more carefully at the claim of bias: how it might be substantiated, and how it should be taken into consideration. The third returns to the example given above, and discusses the prevalence of this sort of error ‘within’ EA, and what can be done to avoid it.

Summary: Using Animal Charity Evaluator’s figures, I estimate the amount donated to an effective animal charity to equal the harm caused by a typical American diet compared to veganism. This figure is surprisingly low: $2-5 per year. This suggests that personal dietary change, relative to other things we can do, is fairly ineffective. Yet most EAs interested in animal welfare are eager that others, including other EAs, stop using animal products. I explore a variety of means of resolving this tension, and recommend a large downward adjustment to the efficacy of animal charities is the best solution.[ref]This is a follow-on from an earlier attempt. The more involved discussion of non-consequentialist approaches I owe to comments on fb and the EA forum in general, and to Carl Shulman’s helpful remarks in particular.[/ref] Continue reading “At what cost, carnivory?”

Doctors have a pretty solid reputation as do-gooders. There are regular news stories about how advances in medical science promise to help more people than ever before. Many of us have had the experience of being ill, seeing our doctor, and being made better.
So it seemed a pretty good career move for a 17-year old wanting to make a difference. Like thousands of others, I applied to read medicine. This is what I wrote on my personal statement:
I want to study medicine because of a desire I have to help others, and so the chance of spending a career doing something worthwhile I can’t resist. Of course, Doctors don’t have a monopoly on altruism, but I believe the attributes I have lend themselves best to medicine, as opposed to all the other work I could do instead.
Was I right? Is medicine a good career choice for someone wanting to ‘make a difference’? Continue reading “How many lives does a doctor save?”
I’m involved with Giving What We Can, a community that pledges to give 10% of their income to whatever best helps in the fight against global poverty. I’ve done a few talks on this over the years, here are the Prezi’s. Feel free to re-use them or their contents (most are permutations on similar points, although the tone and emphasis has varied depending on the audience – it is worth noting many of the figures are a bit out of date). If you want me to give a talk, get in touch!
