This roundtable was organised by Annette Boaz, Huw Davies, Alec Fraser and Sandra Nutley, editors of What Works Now?, in partnership with the Alliance for Useful Evidence at Nesta. Our chair Geoff Mulgan (Nesta) kicked things off with a 1-minute history of the evidence movement, and a challenge that for evidence to truly become part of the air we breathe, it must be genuinely engaged with both the political and media environments. There are also lots of potential opportunities – for example to engage with work on data and analytics.
