Ever been carried away by a moment of compassion - struck by a plea for help from a needy organization promising to help the poor? Ever been inspired to make a difference? Most of us have. We all think about the plight of the underserved, to some degree, and it’s one of the most confounding things to consider the complexities of actually making an impact. We all hear stories (many spoken about in this blog) of good intentions gone horribly awry. And then there are the theories, about whether or not giving - or aid - even helps the poor. Fortunately, there is a light in the darkness of speculation. Esther Duflo and A. Banerjee have found a way to extract solid data from hundreds of studies - showing us the truth about what can actually help people. It’s a must-read for anyone interested in changing the world.
