Which one?
This?
1. to check outcomes, alternatives to measuring seem very weak.
Ja, I agree.
2. why innovate when you can implement evidence-backed innovations
If you're comparing two similar programs, it would be better to go with the one that's backed by evidence. If you think that the causes that aren't backed by evidence are potentially much more effective than those that are, it might make sense to take a chance.
If you can't quantify it, how do you check? Take people's general impressions in anecdotal form? Or what they publish about themselves? The room to biases, fallacies, and inaccuracy is enormous (compared to quantified results, which have their own problems but less so).
You could reason by analogy. You could apply knowledge from psychology, economics, etc. You can extrapolate from the past. Yes, this is speculation, but the alternative is to ignore a large chunk of what matters.
Maybe an example would help explain why I don't think quantifiable results are the only thing that matters. Let's say that if you donate $1000 to the Against Malaria Foundation, there will be a few dozen more QALYs that someone gets to enjoy. In addition, your donation will avert several non-fatal cases of malaria. GiveWell has probably done an OK job of quantifying these benefits. If you consider just these consequences, the AMF appears to offer a great return on your investment.
Other factors could enter into your calculation, however. Preventing malaria may make people more productive, which would probably translate into higher economic growth rates. Poor people definitely would benefit from economic growth. On the other hand, if you care about the welfare of animals as well as that of humans, you might worry that this economic growth would lead to increased consumption of meat, as it has in China (people around here refer to this as
the poor–meat-eater problem). This effect would be difficult to quantify, since it's not clear how much—or whether—donations to the AMF increase economic growth or consumption of factory-farmed animals. It would seem a bit odd not to think about this problem simply because it's difficult to quantify.
Another problem with focusing exclusively on quantifiable aspects of giving is that the vast majority of the impact of your donations will fall in the future. If you care about future and present beings equally, it makes sense to think about how your actions might affect the future. If you think donating to the AMF will increase economic growth, this effect may vastly outweigh the directly measured effect of preventing a certain number of cases.
What about an organization like
Mercy for Animals? It's best known for recording and publicizing instances of animal abuse in factory farms. There's no direct evidence that this leads to people eating less meat or supporting stricter regulations. It seems that it would, but maybe when people see animals being abused they think, "They were asking for it," or "It must be OK to abuse animals since I saw people doing it on TV." If you were in charge of MFA, would you reduce spending on investigations to zero and direct the funds toward more-quantifiable activities? If you could, would you close down the
Global Catastrophic Risk Institute, the
Future of Humanity Institute, etc., and direct the funds to GiveWell, since GiveWell's results are more quantifiable? If you might not, you must not be relying exclusively on quantitative information.
