When Chicago’s youth violence made national headlines, Mayor Rahm Emanuel and business leaders in 2013 launched what they called a game-changing initiative to quell the bloodshed. With prominent executives at the helm and a goal of $50 million in corporate pledges, the new private foundation called Get IN Chicago presented itself as a departure from the usual practice of pumping tax dollars to community groups while paying little heed to the results, said the Chicago Tribune. Get IN would enlist top social scientists to conduct randomized, controlled trials and rigorously evaluate the programs’ outcomes, its press releases said. For the first time, authorities would have data enabling them to scale up and replicate proved strategies.
