New insights from science and behaviour change could lead to significantly improved outcomes, and at a lower cost, than the way many conventional policy tools are used. MINDSPACE explores how behaviour change theory can help meet current policy challenges, such as how to: * reduce crime * tackle obesity * ensure environmental sustainability. Today's policy makers are in the business of influencing behaviour - they need to understand the effects their policies may be having. The aim of MINDSPACE is to help them do this, and in doing so get better outcomes for the public and society.
