When donation challenges become the new high-status thing in the EA community, please remember to credit Ben Kuhn.

Really cool post (I just read it on Ben's blog, but am commenting here because he wants to consolidate discussion in a single place).

A strong majority thought that all matches were fully counterfactually valid, so if this isn’t true of your match, you should say so.

To be crystal clear for people who haven't read the survey, people didn't express an explicit opinion on whether they thought the matches were "counterfactually valid" (using those explicit terms). What they were saying was that they thought more money would go to the charities in the matching cases. (When I first saw the survey it looked like I was being asked a maths problem and I answered it as such.)

Whether they explicitly thought about counterfactuals probably depended on whether they were EAs who were familiar with these - I'd guess that many/most were, since it was posted on Facebook by EAs and would have been of most interest to them. I imagine a typical matching fundraiser audience are merely generally motivated by the matching without explicitly thinking about counterfactuals. I don't think they take there to be even an implication about counterfactuals, which I imagine is why charities are comfortable with matches (which GiveWell apparently think are typically non-counterfactual). So talking about dishonesty is too strong - not being actively transparent about this element is more on the mark.

they thought more money would go to the charities in the matching cases.

In particular, they thought that for each $10 donated, a full additional $10 would go to the charity if the match was still active. (Some people thought that more money would go to the charity in the matching case, but less than the full $10.)

Results from a survey of people's views on donation matching — EA Forum

Since a lot of people lately have been discussing donation matching and the various issues about counterfactuals that surround it, I ran a survey a couple weeks ago to answer various of my questions about donation matching.

You can read the full post here. I'm not going to cross-post the whole thing because it becomes difficult to keep the two versions in sync, but I'll include the "conclusion for matching donors" below to pique your interest. (Note that because it was only a survey of a small convenience sample, you should put limited weight on these conclusions! But I think they're useful nevertheless.)

Be transparent about your matching

Where will any unmatched funds go? Will they be donated to the same organization anyway? Given to a different charity? Burned? A strong majority thought that all matches were fully counterfactually valid, so if this isn’t true of your match, you should say so. This could affect how much people donate, and how deceived they feel, so it’s very important to be totally honest here.

One thing that I didn’t look at in this survey, but that merits future research, is another type of “partial validity” in which unmatched funds don’t go to the same charity, but go to another charity, sometimes a quite similar one. It’s hopefully clear that this always happens for foundations, but it’s not clear for private donors like HEA’s anonymous matcher or one’s friends. It’s probably wise to be transparent about this in your fundraiser as well.

Separately from concerns about honesty, I think transparency in matching is great for other reasons as well. It seems to me that by far the biggest benefits of many EA fundraisers are not just that they raise additional funds—the best part is the flow-through effects from getting people to be more public about their giving, to discuss effective altruism more, and to get their friends interested. From that standpoint, it seems like a huge win to use the matches to introduce people to two central practices of effective altruism, transparency and counterfactual reasoning. It would also make the campaigns stand out more from typical fundraisers.

Consider running a challenge instead of a match

The survey suggested that people found challenge fundraisers just as compelling as matches, and seemed to reduce their donations less when the challenge target was reached than when a match expired. Furthermore, with challenges, the counterfactual effects are much clearer: it’s obvious where your money went, and the funding dynamics are much more intuitive.

This is consistent with my interpretation of the donation matching literature, where I wrote that I expected matches to work mostly through social proof and urgency effects rather than through making people’s donations bigger (and found, consistent with this, that changing the amount of the match tended not to matter). Challenge fundraisers don’t make people’s donations bigger like matches do, but they share the same urgency effect and function as stronger social proof. So it’s not surprising that they work just as well.

Consider running a larger experiment

This survey produced some useful info, but it would be even better to have actual field experiments (and a larger sample size). The academic literature on matches is sparse enough, and the literature on challenges even more so. So any additional experiments could add a lot to our knowledge.

Once again, check out the full post if you're interested in learning more, or have questions that aren't answered above. I hope this is useful to those considering running matching campaigns!
