GiveWell exists to really assess the impact of charities, not just whether they're well-run, and it's screened hundreds of charities and currently is recommending only three, of which the Against Malaria Foundation is number one.
GiveWell tu je, aby hodnotila nejen jak jsou charity vedeny, ale také jejich dopad. Hodnotí stovky různých charit a v současné době doporučuje pouze tři, z nichž nejlepší je Against Malaria Foundation.
