I couldn’t find any field experiments on social media campaigns. It seems pretty hard to study. Actually, Charity Science might be in an ideal place to look at this with their birthday/Christmas fundraisers...
We haven’t directly tested matching scientifically yet, though we’d definitely like to. Our closest is in the write-up you mention “The Power of Donation Matching” where we anecdotally observed a time-ordered effect of introducing “live” donation matching (though this could be due to other factors, and isn’t evidence of matching overall).
Yeah. If it turns out that the true effect is smaller than you observed in that post (which it may well not be—lots of heterogeneity), my guess would be that the spike was partly caused by some interaction with people promoting it at the same time. But again, it’s super hard to tell without randomization, because the effects vary so much.
