The Limits to Evidence‐Based Policy: Evidence,Emotion and Criminal Justice1

While ‘evidence‐based’ or ‘rationalist’ approaches to criminal policy may appeal to technocrats, bureaucrats and a number of academics, they often fail to compete successfully with the affective approaches to law and order policies which resonate with the public and which appear to meet deep‐seated psychological needs. They also often fail to recognise that ‘policy’ and ‘politics’ are related concepts and that debates about criminal justice are played out in broader arenas than the academy, the bureau or the agency. To be successful, penal reform must take account of the emotions people feel in the face of wrongdoing. Further, successful reform must take into account changes in public ‘mood’ or emotions over time and be sensitive to different political and social cultures. This article argues that criminal justice policies are more likely to be adopted if, in addition to the gathering and presentation of evidence, they recognise and deal with the roles of emotions, symbols, faith, belief and religion in the criminal justice system. It also recognises that evidence alone is unlikely to be the major determinant of policy outcomes and that the creation and successful implementation of policy also requires extensive engagement and evidence‐based dialogue with interested and affected parties. This necessitates a different kind of modelling for evidence‐based policy processes.
