80,000 Hours' average cost per plan change this year was more like £300.
Approximately what is that £300 spent on? Is it staff time, and if so what is most of that staff time spent on? Talking to individuals and persuading them? Researching what careers would work for them and telling them? Or something competely different?
A sharper way to put the question would be by how much this news should make us discount GiveWell's claims about a $1000 donation can do. (Also because not everyone's going to take the GWWC pledge of course. The key thing is simply that they donate and donate wisely.)
