From 1996–1997, NIJ sponsored the Project on Policing Neighborhoods (POPN), which studied police and citizen interaction and behavior in St. Petersburg, FL, and Indianapolis. This Research for Practice discusses a study that used POPN data to determine patterns in police supervisors' attributes and behavior. The study identified four main supervisory styles: traditional, innovative, supportive, and active. Each style had benefits and drawbacks, but the researchers found that the "active" supervisory style, i.e., leading by example, had the most influence and led to more problem-solving policing in the field.
