The mission of the Philadelphia Behavioral Science Initiative is to bring leaders from government and academia together to discuss how the social and behavioral sciences can be deployed to create more effective policies and programs in Philadelphia. The White House Social and Behavioral Sciences Team, the UK’s Behavioral Insights Team, and ideas42, among others, have demonstrated the social and economic value of an evidence-based and people-focused approach to policy-making. We believe this value can be realized to an even greater degree at the local level, here in our city.
