Reducing unnecessary warrants and jail time. Alissa Fishbane, Managing Director at ideas42, and Dr. Aurélie Ouss, Assistant Professor of Criminology at the University of Pennsylvania, joined the podcast to talk about their study to reduce the number of arrest warrants for failure to appear in court in the New York City criminal justice system. The guests highlighted the use of behavioral interventions, or nudges, that were low cost and easy to implement. They also shared how other local governments can apply behavioral science practices.

Behavioral interventions or "nudges" that improve communication of critical court information may be more effective at improving court attendance for low-level criminal offenses than increasing threats of further punishment, according to a new study published in the October 9 issue of Science.

Redesigned ticket—and text message reminders—led to a 13% drop in missed court dates.

Behavioral “nudges” can prevent people from facing an arrest warrant for a missed court date.

A three-year collaboration researched the underlying behaviors associated with missing a court summons—and how to use behavioral science interventions to change those behaviors.

By re-thinking the look of a standard summons alone, the failure-to-appear rate for people who received the redesigned paperwork dropped by 13%.  Many of the tickets also collected cell phone numbers from the defendants, allowing the city to try some text interventions. Together, the new summons and text reminders caused a 36% drop in those skipping court.

Texting people reminders makes them more likely to show up for court, according to a pilot program in New York City.

After a pilot testing which messages work best, the city reports it has cut failure-to-appear rates by 26 percent.

New York City’s pilot program of texting reminders to people about upcoming court dates has been a success so far, Mayor Bill de Blasio said. 

Borrowing techniques from the advertising world, city officials consulted with behavioral economists who redesigned the tickets.
