"This list reflects a significant amount of work by many people. I want to thank Dean Karlan and his colleagues at Innovations for Poverty Action (IPA), who have done many of the randomized controlled trials that are the science behind these recommendations. GiveWell and Giving What We Can have contributed significantly to my thought process. Jon Behar, a member of our core staff at The Life You Can Save, has helped me develop the list. Additionally, I have personally thought a lot about what charities to include and how to order them."
