The Sibyl System is a fictional artificial intelligence from the anime and manga series Psycho-Pass. It functions as a central authority that assesses the mental states of citizens in a dystopian society. By analyzing various data points, the system determines an individual's potential for criminal behavior, assigning them a "Crime Coefficient" that influences their treatment by law enforcement. In this world, the Sibyl System is responsible for maintaining public safety and order. It employs a network of enforcers, known as Inspectors and Enforcers, who act on the system's judgments. The system raises ethical questions about free will, privacy, and the morality of preemptive justice.
