Administration &Society, Ahead of Print.
Behavioral insights teams (BITs) employ behavioral experts and policy professionals to collaboratively improve public policy. Most evaluations of BITs focus on the interventions that BITs develop, but not the functioning of BITs. Here, we report the first comprehensive evaluation of a BIT, the Behavioral Insights Group Rotterdam. We investigate how its resources were used, for what activities, with what outputs, and to which effects. Using quantitative and qualitative methods, we derive nine propositions to describe and improve the integration of behavioral insights into public policy and administration.
