In April, the NYPD informally introduced its public opinion monitor, also known as the “sentiment meter,” during CompStat, the weekly meetings in which top brass interrogate precinct commanders about crime trends. Precincts now receive a monthly “trust score” along with rankings that measure overall satisfaction with police performance and how safe residents feel. The data is culled from questionnaires administered through about 50,000 smartphone apps, including Candy Crush and WeatherBug, as well as traditional landline calls. Facebook and Instagram began to advertise links to the surveys in June.
