Yikes; this is pretty concerning data. Great find!
I’d be curious to hear from anyone at GWWC how this updates them, and in particular how it bears on their “realistic calculation” of their cost effectiveness, which assumes 5% annualized attrition. (That’s not an apples to apples comparison, so their estimate isn’t necessarily off by literally 10x, but it seems like it must be off by quite a lot, unless the survey data is somehow biased.)
We’re definitely aware that Giving What We Can’s 2015 analysis comes away with a more optimistic conclusion than other more recent data sources like the EA Survey indicate (and I believe the Slate Star Codex survey, though I haven’t seen a careful analysis of that one as it bears on Giving What We Can). We’ve just made some improvements to the donation recording platform, and once a few last things are ironed out we’ll be sending out reminders for members to record their donations that may not have been recorded. Once people have had time to respond to those reminders, we plan to do an update on our 2015 estimates of members’ follow-through.
