Frequently Asked Questions About Effective Giving
What defines the best charities for maximum impact?
The best charities for maximum impact are defined by their commitment to effective altruism principles: high transparency, rigorous evaluation of interventions, and a primary focus on cost-effectiveness. They choose areas where a dollar can go furthest, often in global health or poverty alleviation, to generate the greatest positive outcome.
How can I find evidence-based charities for global health?
To find evidence-based charities for global health, you should look for organizations that publish clear, third-party verified data on their outcomes. Many of the groups on this list are proven to be most cost-effective charities for donation by implementing interventions — like bed net distribution or vitamin supplementation — that have been scaled due to successful, scientific trials.
Do effective giving organizations also address long-term global risks?
Yes, our list includes charities dedicated to addressing massive, long-term threats to humanity. This includes nonprofits focused on catastrophic risk like extreme poverty, future pandemics, and the long-term governance of powerful new technologies like artificial intelligence (AI) to ensure a safe future.
What kind of measurable impact can I expect from my donation?
By donating to charities with high impact per dollar, you can expect your funds to be tracked against measurable metrics, such as: the number of people protected from malaria for a specific cost, the amount of income directly transferred to a family in poverty, or the estimated number of animals spared from suffering due to advocacy changes.
