Intervention Reports - August 2017 Version

We have published a more recent version of this page. See our most recent version of this page.

Last updated: August 2017

This page lists interventions we have researched to identify candidates for our list of top charities. Our priority programs have the following characteristics:

  • The evidence for their effectiveness appears to have relatively high external validity and thus generalizability: it is relatively clear which components of the program are important for effectiveness, and thus we expect a higher-than-usual chance of being able to meaningfully assess a charity's impact when it focuses on these programs.
  • They appear to be potentially highly cost-effective.

Table of Contents

Below we list the programs we have considered as potential priority programs.

For older versions of this page, see the 2009 version, the 2012 version, and our summary of our 2009-2011 criteria for evaluating programs.

How We Identified Programs for Investigation

We first started working on identifying promising programs for investigation in 2009. At that time, we focused on reviewing two sources:

  • The Copenhagen Consensus, the only case we have seen of an independent panel of experts attempting to identify the most promising philanthropic investments (discussed more here)
  • Millions Saved, the best collection we have found of large-scale, well-documented past successes in international aid (discussed more here)

If a program was both featured in one of these two publications and similar to a program focused on by one or more of the charities we reviewed, we generally conducted further investigation into the program. Details on which programs are featured in these two publications, which similar programs are focused on by the charities we've reviewed, and which programs we investigated are available here (XLS).

Over time, we have added programs to this list; we have added any program that seems to potentially fit the criteria laid out at the top of the page. We place more emphasis than we previously did on external validity, and less on estimated cost-effectiveness, for reasons laid out in a 2012 blog post.
