No conversation about social impact is complete without an understanding of randomized control trials, or RCTs. In this episode, we delve into what they are and how they measure impact with Rachel Glennerster, the new chief economist at the Department for International Development (DFID) in the UK. In an episode recorded in London, Glennerster gives her insights on the randomization movement, and also talks about the divide between academics and policy makers, and why it’s important that they find ways to work together better.
