| 2009|| March || External citation || Australian philosopher {{w|Peter Singer}} publishes ''{{w|The Life You Can Save}}''. Singer writes: {{Quote|When I speak about why we ought to be doing more to help the world's poorest people — something I do often — the most frequent question I get is: how can we know that our donation will really help the poor? Until GiveWell came along, it was difficult to give a convincing answer to that question. Previous charity-rating organizations just looked at how much of a charity's income went to program expenses, rather than administration - and it doesn't take much thought to realize that that figure tells you nothing about how effective the charity's programs are. GiveWell has filled a huge gap, and at the same time has started a major trend towards greater transparency and demonstrated cost-effectiveness in the charitable world.<ref name="What Others Are Saying"/>}}
