How can we demonstrate the public value of evidence-based policy making when government ministers declare that the people ‘have had enough of experts’?

Recent political campaigns on both sides of the Atlantic have led some to argue that we live in the age of ‘post-factual’ or ‘post-truth’ politics, suggesting evidence has a limited role in debate and public policy. How can we demonstrate the public value of evidence-informed debate under those circumstances? Survey evidence on public attitudes to expertise offers some hope that the tone of much of this debate is unduly pessimistic. While policy-making always develops in an environment where evidence is contested, this paper will argue that understanding of the routines through which Ministers work and assimilate evidence is actually under-researched. Not only are Ministers open to evidence, but there is an institutional grounding for evidence-based policy in government. Meanwhile, the creation of devolved institutions has created new sites in the UK for evidence-based policy-making, despite the political tensions between UK and devolved governments. Drawing on academic and think tank insights, and experience as a Welsh Government Minister between 2007 and 2016, this paper argues for three key approaches for the academic community to adopt: understanding the temporal focus of ministers, building trust amongst ministers and those who advise them in the evidence-promoting capacity of the academic policy community, and shaping the wider authorising environment, including the media that contributes to the framing of key policy debates
