More to explore on ‘Differences in Impact’

GiveWell and Open Philanthropy

GiveWell and Open Philanthropy are sister organizations in the effective altruism community. Both seek to identify outstanding giving opportunities, but they use different criteria and processes.

GiveWell has an emphasis on evidence-backed organizations within the global health and wellbeing space, while Open Philanthropy also supports high-risk, high-reward work, as well as work that could take a long time to pay off, in a variety of cause areas. We think this illustrates interesting methodological differences between attempts to answer the question “How can we do the most good?”.
