Ministers from Andrew Lansley toBaroness Neville-Jones have claimed that it does. In a recent Lords debate, Neville-Jones invoked thisnotoriously Blairite phrase to justify the new strategy on illicit drugs.The past two governments have both used claims to evidence to brush off accusations of ideological policymaking. The apparent gaps between these claims and the resulting policies have led to great scepticism.Some have stated that policy makers ignore research, and so create strategies that are “evidence-free”.Others suggest that they deliberately set out to use only the studies that suit their arguments, and so create“policy-based evidence”. In a recent article in the Journal of Social Policy I describe how both these claimsfail to capture the complex reality of how civil servants use evidence.In 2009, I spent six months working on an “out of academic life” placement as a policy adviser in a team atthe heart of Whitehall. Surrounded by bright, industrious, fast-tracked young men (and a few similarlyimpressive women), I responded to requests for information, worked up policy proposals and generally tookpart in the policy-making process.I soon found out that this was a world saturated with evidence. Huge volumes of government-collected data,independent reviews, think tank papers and academic articles – alongside media stories and examples frompopular TV programmes (The Wire was a contemporary favourite) – were folded into our daily discussionson how to improve governmental action.The problem was not a lack of evidence, but the sheet quantity of data and opinions that was available. Andmost of it was unsuitable for answering policy questions. Policy-makers want to know what the costs andeffects of a policy option will be, and on whom they will fall. It is rare for research to provide definitiveanswers to these questions. A colleague spoke of a “depressingly similar pattern” of looking for high-qualityevidence, but then ending up with some anecdotes and “what you can garner through a few field visits”.Faced with a lack of conclusive evidence and an ongoing need to keep churning out the policy papers, mycolleagues and I engaged in a process of “selling” policies. To be recognised by our peers and seniors forbeing useful and productive we had to get these policies accepted by all the departments who shared aninterest in them. To achieve this, we paid great attention to narrative. What story is the policy telling? Howcan it be made more persuasive?Given that most of these tales were being told in the form of PowerPoint packs, the best way to increase theirimpact was to include “killer charts”. These graphs reduced the world to a usual maximum of two variablesand they aimed to make policy implications self-evident. They excluded the possibility of uncertainty.Uncertainty – as my colleagues let me know whenever I tried to insert academic caveats – is the enemy ofpolicy-making.Even where the evidence did lead to a particular conclusion, this did not mean that it would feed into policy.In a meeting on sentencing policy, I observed a well-informed debate using research on the effects ofincreased imprisonment. My colleagues eventually agreed that it was not the best use of public money, butthey ruefully concluded that this evidence would not be welcomed by the ministers and special advisers ofthe day. So they left it out of their recommendations.I found many examples where the scope of the policy debate was constrained by my colleagues’ anticipationof the kinds of knowledge that would be of use to their bosses. If civil servants hope for swift careerprogression, they have to develop useful links to people who are more senior in the hierarchy. To do this,they have to prove themselves to be useful.Civil servants learn from their colleagues that certainty is more useful than accuracy, and action is betterthan contradiction. This means that – for the team I worked with at least – evidence was far more likely to beused if it fitted with the story that was already being told; a story that usually emerged from a complexinteraction of the evidence with the interests of the politicians, special advisers and civil servants who wereits joint authors.This suggests that policy is not evidence-free. Neither is the chosen evidence simply policy based. It doesmean that there is some systematic distortion of the use of evidence in ways that suit the interests of thepowerful social groups that constitute the British state. And this is certainly not “evidence-based policy”.Professor Alex Stevens is professor in criminal justice at the University of Kent and author of Drugs, Crimeand Public Health (Routledge, 2011).This article was first published in Public Servant magazine.

In Whitehall, academic research is far more likely to be used if it fits with the story already being told
