Andrew Leigh MP responds to yesterday's post about the limitations of randomised control trials in assessing aid effectiveness:

Sam, thanks for the thoughtful post. I'm a fan of Chris Blattman's blog and academic work. In fact, I discussed his paper on Ugandan child soldiers in the Q&A after my Lowy Institute speech.

However, I don't think there's a conflict between Chris' point that not everything can be randomly evaluated and my point that some things can be randomly evaluated. The optimal share of evaluations that are randomised trials isn't 100%, but nor is it 0%. Which means we need to start doing more randomised trials.
