Normally, we focus on identifying outstanding charities, and minimize the time spent on opaque or otherwise lackluster ones. But lately, we’ve gone into a bit more detail about our take on several of the best-known and most appealing charities out there.

What all of the charities below have in common is that (a) we have major questions and concerns about their activities; (b) the information necessary to see how serious these concerns are does not seem to be available. (In most cases our assessment is based on significant back-and-forth with the charities themselves, though in some cases we are going off their website.)

• Kiva: commonly perceived as a way to (a) make interest-free loans to (b) entrepreneurs you personally select. In fact, it is neither. (See GiveWell Board member Tim Ogden’s summary of the recent discussion/controversy.)

  We ultimately see a Kiva “loan” as a gift to a microfinance institution, and we have major concerns about supporting any but the most outstanding microfinance institutions as well as concerns about Kiva’s due diligence process specifically.

• Grameen Foundation and other large U.S. microfinance charities: in addition to our general concerns about microfinance charities (and the fact that these charities have not provided the information that would address them), we find that these organizations are rarely even clear about what their value-added is. Also see the disappointing (and eye-opening) evaluation of the Village Phone program.

• Heifer International: commonly perceived as a way to “give a cow to a poor family as a gift,” but this is in fact a donor illusion -donations support Heifer International’s general “agricultural assistance” activities. We have concerns about this general area and concerns about giving livestock specifically. Neither Heifer’s website nor its grant application have provided the kind of information needed to address these concerns.

• Smile Train: Prof. Steven Levitt of Freakonomics sees it as using an innovative model to deliver cleft surgeries for $250 apiece. Our analysis suggests that it has “more money than doctors” and that it is therefore out of room for more funding. Smile Train’s recent removal of the charts we questioned and its own explanation of why it is giving grants to other major charities appear to support our analysis. In addition, we have major concerns about surgery charities that Smile Train has not provided enough information to address.

• UNICEF offers donors the chance to “buy” vaccines and other items. We suspect that this offer is a donor illusion, but the larger issue is that UNICEF provides almost no information at all about its huge variety of activities and how they are going. Most giant international aid charities (Save the Children, World Vision, etc.) are similarly complex and opaque, with CARE coming the closest to meaningful transparency.

• The Acumen Fund stresses its metrics-driven approach to “patient capital,” investing in businesses that aim for long-term sustainability (i.e., profitability) and social impact. As of now, we see no substantive available information about its track record.

• The Robin Hood Foundation also stresses its emphasis on metrics, quantification, and analytical thinking. But we have found that it is unwilling to share any information about the results of its grantmaking. (Note that it also pushes the “0% overhead” donor illusion.)

• The Millennium Villages project states that it is “demonstrating that it’s possible to escape … extreme poverty” (front page of its website). As far as we can tell, very few results have been demonstrated to date, with a few boosts in crop yields as its main evidence of impact - evidence we feel is highly questionable.

• The Worldwide Fistula Fund has been praised by Nicholas Kristof as “giving new life to the pariahs.” Our assessment is that the Fund is pushing a debatable agenda whose effectiveness has yet to be shown.

• The Carter Center is, in our view, by far the “best bet” (for an individual donor, our focus) of the charities listed in this post. It has achieved substantial, demonstrable impact in the past through its work on guinea worm eradication, and unlike all of the charities listed above, it publicly discloses substantive technical information on the impact of its past activities.

  However, there is a crucial piece of information missing: how it allocates its budget between programs (in particular, how much it spends on its stronger and better-documented vs. more questionable programs). It has declined to share this (basic, in our view) information in repeated exchanges.

We think the above charities are fairly representative of “average” charities in international aid. Some tell better stories than others and some have more disclosure than others. But in almost all cases, international aid charities are (a) carrying out complex projects that can fail to do good (or even do harm) in a variety of ways, and (b) not systematically sharing the information that would make it possible to assess how their work is going.

GiveWell is devoted to finding charities in which we can have more confidence. We’ll be discussing our two top-rated charities working internationally in forthcoming posts.

What’s wrong with this “evidence of impact” for high-profile charities?

• The Millennium Villages project’s main evidence of impact so far appears to be increasing crop yields by a factor of 4-15x in 3 villages. (H/T to the recent coverage of Millennium Villages on Aid Watch)
• A KickStart evaluation (available on our website (DOC)) reports that “Family/household incomes of 3,000 farmers increased by 100% within 24 months following acquisition of micro-irrigation pumps.”
• The Carter Center’s agriculture program “provides the tools and means to help farmers in sub-Saharan Africa increase their crop yields through agricultural development, sometimes two- or even threefold.”

Among other possible problems, two major issues jump out:

1. No context on what “normal” variation in incomes looks like for poor farmers. Some years have more favorable weather - and local economic situations - than others. Enough that one year’s income or crop yield could be double another’s? 4x? 20x?

Unfortunately, one of the better pieces of “evidence” that jumps to mind is a 75-year-old novel, The Good Earth, whose farmer protagonist is comfortable one year and has literally zero income the next, for no other reason than the weather. If a given year’s yield were close enough to zero, the next year could be a huge increase (2x, 4x, 20x or more) simply by returning to normal.

I have seen little information on the local year-to-year volatility that poor farmers can experience, but I imagine that it (a) varies greatly from region to region and (b) could easily involve incomes falling and jumping by enormous amounts.

None of the above reports provide any context on this question, beyond qualitative statements about how favorable the rains were in each year examined. None of them employ any sort of “comparison group” of farmers (aside from one vague reference to “farms not using improved seeds and fertilizers” in the Malawi Millennium Village). Ultimately, none accomplish one of the most basic goals of an evaluation: giving a sense of how likely the “gains” they describe are to have arisen by pure chance.

With larger sample sizes, we might be able to use country-level volatility for context. But that brings me to the next problem.

2. We have no assurance that the described gains are representative, as opposed to “cherry-picked.”

All of the above organizations have reputations for consistent and thorough monitoring and evaluation, yet in all cases, we find ourselves looking for “impact” from a tiny subset of their projects.

• The Millennium Villages evaluation “includes results from the Sauri baseline survey, annual reports from Sauri and Koraro and crop-harvest data from Malawi.” How were these three chosen from among the 78 villages mentioned in the abstract?* The report doesn’t say.
• KickStart implies that it is constantly and consistently tracking impact, yet the report linked above discusses a single project over a single year.
• The Carter Center is somewhat explicit that its number is a “high-end” one (”sometimes two- or even threefold”). Examining the most recent annual report for its agriculture program shows a very small upward trend, if any, in crop yields across the countries in which it is working.

Some ways to produce more compelling evidence of impact

1. Be clear about what is being measured and what is being published, and when. It seems to us that in this area, charity evaluation lags far behind clinical trials, which are constantly registered before they are complete so people can track their progress. (The Poverty Action Lab is similarly transparent with its own ongoing projects.)
2. More sample size; more context; use of comparison groups. Discussed above.
3. Look for more sustained improvements in people’s lives. One measure I find superior to straight “income” or “crop yields” is asset accumulation. A jump in income could be temporary; if someone upgrades their roof or sanitation, it’s likely that at least they expect the gain to be a real and lasting one. The Village Enterprise Fund’s evaluation is one of the better charity evaluations I’ve seen in the area of economic empowerment, partly because it focuses on standard of living rather than a simple measure of income.

*It’s possible that the yields mentioned are for “clusters” of villages rather than individual villages; there are only 12 clusters. However, the source documents available for Sauri and Koraro appear to be at the village rather than the cluster level, and the details of how the measurements were made are unclear.
