You donate some money to a charity in the hopes that it will (a) carry out a project that (b) improves people’s lives. In order to feel confident in your donation, you should feel confident in both of these.
In most areas of charity, we feel that people overfocus on “did it happen?” relative to “did it work?” People often worry about charities’ stealing their money, swallowing it up in overhead, etc., while assuming that if the charity ultimately uses the funds as it says it will, the result will be good. Yet improving lives is more complicated than charities generally make it sound (see this recent post of ours). This partial list of failed programs is made up entirely of programs that appear to have been carried out quite competently, and simply didn’t improve the lives of clients.
In international aid, the relative importance of “did it happen?” grows for a couple of reasons:
“Did it happen?” is a question that can largely be answered by informal, qualitative spot-checks. That’s why we would like to see more and better qualitative evidence. By contrast, to know whether a program worked, you need to somehow compare what happened to clients with what would have happened without the program - something that is often hard to have confidence in without formal outcomes tracking and evaluation.
Therefore, we believe that the role of site visits, qualitative evidence, spot-checks, etc. is likely more important in international giving than in domestic giving. In international aid, delivering proven programs (particularly medical ones) is a large part of the battle. In the U.S., most reputable charities are probably doing what they say they’re doing; the question is whether what they’re doing is effective.
