Frequently Asked Questions

  • One for the World prioritizes highly cost-effective nonprofits, as defined by effective giving. This approach to donating prioritizes improving the most lives and averting the most deaths for every dollar donated.

    To identify these nonprofits, we have partnered with GiveWell, an independent nonprofit evaluator, to compile a list of recommended nonprofit organizations based on extensive research and analysis.

    We are committed to the idea of effective giving - we know that, on average, the most effective nonprofits in the world do 100-1000x more good than an average nonprofit. Accordingly, we do not support donations to nonprofits other than those recommended by GiveWell at this time.

  • Effective giving prioritizes ‘impact per dollar donated’, or ‘cost effectiveness’. This approach requires finding organizations that have:

    • Evidence of effectiveness, ideally multiple randomized controlled trials that show a  lasting, positive effect from the intervention.

    • Cost-effectiveness, or the ability to deliver that intervention in the leanest way possible, and more cheaply than competitors.

    • Room for more funding, which will allow the program to deliver more of its services at roughly the same cost, within around 3 years of receiving a donation.

    Crucially, effective giving tries to persuade donors not to overweight more ‘personal’ drivers of donations, such as whether we know someone who works at the nonprofit; whether it helps people like us or people we know; whether it works in our local area; or whether we volunteer there. While supporting these nonprofits is good in most cases, we hope that every donor can give at least 1% of their income just based on cost-effectiveness.

  • Approximately 50 organizations make up the effective giving movement worldwide. These include:

    • Nonprofit evaluators, such as GiveWell, Founder’s Pledge and Animal Charity Evaluators;

    • Pledge-based organizations, such as Giving What We Can and Founder’s Pledge;

    • Organizations targeting particular geographies, such as RC Forward, Effektiv Spenden and Ayuda Efectiva;

    • Organizations targeting particular audiences, such as High Impact Athletes;

    • Other fundraising organizations, such as The Life You Can Save and Giving Multiplier.
