  • Interesting blog from the Global Innovation Fund, discussing results from an attempt to replicate the Kenyan sugar daddies RCT in Botswana, why they got different results, and how policy is reacting to this. “At some point, every evidence-driven practitioner is sure to face the same challenge: what do you do in the face of evaluation results that suggest that your program may not have the impact you hoped for? It’s a question that tests the fundamental character and convictions of our organizations. Young 1ove answered that question, and met that test, with tremendous courage. In the face of ambiguous results regarding the impact of No Sugar, they did something rare and remarkable: they changed course, and encouraged government partners and donors to do so as well”
  • How to help farmers to access agricultural extension information via mobile phone? Shawn Cole (Harvard Business School) and Michael Kremer (Harvard University) gave a recent talk on this, drawing on work they’ve been doing in India, Kenya, Rwanda, and elsewhere. Video here and paper on some of the India results here.

The RCT results seem to point a broader replication limitation of the methodology itself.

Context (social, behavioral, contextual, etc.) can mean quite a bit, and RCTs don't factor this in.

Nancy Cartwright has written about both the power and the limitations of RCTs.
