One group I’m especially interested in is people who were active in EA, took the GWWC pledge, and then drifted away (eg). This is a group that likely mostly didn’t take the EA Survey. I would expect that after accounting for this the actual fraction of people current on their pledges would be *much* lower.
Since we don’t know the fraction of people keeping their pledge to even the nearest 10%, the survey I would find most useful would be a smallish random sample. Pick 25 GWWC members at random, and follow up with them. Write personalized handwritten letters, place a phone call, or get a friend to contact them. This should give very low non-response bias, and also good qualitative data.
