This report covers a wealth of policy applications either implicitly or explicitly informed by behavioural insights (BIs). It reviews institutional developments and puts forward a comparative framework (PRECIS) describing behavioural insight teams with six key features. The Report reaches four main conclusions: i) in terms of capacity-building, there is significant dynamism and growing appetite to apply BIs to policy-making; ii) links between policy-making and academy communities can be strengthened and analysing large datasets offers great potential; iii) systematic application of BIs throughout the policy cycle can advance evidence-based policy-making; iv) need of more research on the long-term impacts of policy interventions.
