The evidence
The Effectiveness Gap Nobody Talks About
Experts in one comparative study estimated the best charities are no less than 100 times more cost-effective than the average one, while ordinary donors guessed the gap was only 1.5 to 2 times (Caviola et al., Judgment and Decision Making).
What It Actually Costs to Save a Life
GiveWell's top-rated charities have delivered a death averted for roughly $3,000 to $5,500 through interventions like seasonal malaria prevention and vitamin A supplementation (GiveWell, 2024). Insecticide-treated bed nets cost about $4 to $6 apiece to produce and distribute.
Careers Multiply Impact the Same Way
80,000 Hours estimates some career paths open to a typical graduate carry over 100 times the positive impact of others, largely because talent and funding are so unevenly distributed across causes.
Hundreds of Billions Given, Little of It Guided by Evidence
Americans gave an estimated $592.5 billion to charity in 2024, about 2.0 percent of GDP (Giving USA 2025). The overwhelming majority of that money is allocated on emotion or local ties rather than any comparison of cost-effectiveness.
The Most Neglected Problems Get the Least Money
Factory farming affects roughly a trillion animals a year but receives approximately 1,000 times less philanthropic funding than global health causes (80,000 Hours).
A Growing Community Is Already Proving the Model
Giving What We Can's 10% Pledge has been taken by over 10,000 people, moving more than $500 million to date. Open Philanthropy has directed more than $4 billion in grants since 2014 using explicit cost-effectiveness research.
What we can do
Phase 1 asks individual donors to redirect even 10 percent of their giving toward charities vetted by evaluators like GiveWell instead of giving on instinct. Phase 2 asks people early in their careers to weigh problem-choice as heavily as job title, using frameworks like 80,000 Hours' problem rankings. Phase 3 pushes foundations and employers to make cost-effectiveness data the default lens for institutional giving.
