How GiveWell and mainstream policymakers compare the “good” achieved by different programs

In a previous blog post, we described how we use cost-effectiveness analyses when deciding which charities to recommend to donors.

Today, we published a report that discusses how GiveWell and other actors, such as governments and global health organizations, approach one of the most subjective and uncertain inputs into cost-effectiveness analyses: how to morally value different good outcomes.

September 2017 open thread

Our goal with hosting quarterly open threads is to give blog readers an opportunity to publicly raise comments or questions about GiveWell or related topics (in the comments section below). As always, you’re also welcome to email us at or to request a call with GiveWell staff if you have feedback or questions you’d prefer to discuss privately. We’ll try to respond promptly to questions or comments.

You can view our June 2017 open thread here.

Why we’re allocating discretionary funds to the Deworm the World Initiative

Many donors who give through GiveWell’s website choose to donate to support “Grants to recommended charities at GiveWell’s discretion,” rather than selecting a specific recommended charity or charities as the target of their gift.

We periodically grant these “discretionary funds” to what we see as the highest-value funding opportunities among our top charities. We last granted discretionary funds in April; then, we granted $4.4 million to the Against Malaria Foundation and $0.5 million to the Deworm the World Initiative.

Since we last allocated funds, we received an additional $1.25 million in discretionary funds that we recently granted out. We also hold roughly $1 million in discretionary funds that we plan to grant out in the next month or two. We plan to grant all of this funding to the Deworm the World Initiative.

Recommendation for donors

We continue to recommend that donors give 100% of their donation to the Against Malaria Foundation (AMF). In other words, although we’re choosing to grant discretionary funds to Deworm the World, we don’t believe that donors who rely on our recommendations should adjust their giving at this time. We explain the rationale for this below.

From the archive: 6 tips on disaster relief giving

We’ve received several questions about donating in response to Tropical Storm Harvey. We wanted to share this post, which was originally published in 2013, with our advice for disaster relief giving. We’re unsure if bullet points #4 and #5 still apply, as it has been a few years since we last investigated giving opportunities for disasters, and we have mostly considered international disasters.

Our general advice on disaster relief giving:

Update on GiveWell’s intervention research in 2017

One of our major goals for 2017 is “intervention prioritization,” our work to assess a large number of programs (interventions) as potential GiveWell priority programs we’d be interested in recommending charities working on.


This post will provide a brief overview of our intervention work this year, focusing on the interim and full intervention reports we’ve published in 2017.

Programs we plan to continue investigating:

Programs we decided not to prioritize additional research on:
