Each of these intervention areas were researched for up to forty hours (using this outline) to determine whether our team could and should create an effective charity in that area. While we have ruled out these twenty-two interventions at this stage for our team going forward, we still think many of these interventions could be worth considering as donation targets or for other teams to found charities in. Also, some interventions were ruled out largely because they already had an exceptionally strong charity recommended by GiveWell. Additionally, all ratings were relative to other intervention areas on our list, and the interventions that we ruled out are likely still unusually cost-effective and evidence-based relative to average global health programs.
Below we attempt to provide a quick summary of the research we have conducted and published including links to more detailed information. This is not meant as a full justification or explanation so much as to give a sense of our views on the weakest and strongest of interventions we looked at. Over time we will be posting many blog posts explaining our thinking and outlining our research on interventions that did make the cut. We will also eventually start posting our ideas about which concrete charities we think may be high value and why.
