_Psycho-Pass_ is tech used in a futuristic Japan governed by the Sibyl System (シビュラシステム, _Shibyura Shisutemu_ ), a powerful biomechatronic computer network which endlessly measures the biometrics of Japanese citizens' brains and mentalities using a "cymatic scan." The resulting assessment is called a Psycho-Pass (サイコパス, _Saikopasu_ ), which includes a numeric Crime Coefficient (犯罪係数, _Hanzaikeisū_ ) index, revealing the citizen's criminality potential, and a color-coded Hue, indicating stress level of the person and alerting law enforcement to other data, as well as the improvement (clearing) or decline (clouding) of said Psycho-Pass. When a targeted individual's Crime Coefficient index exceeds the accepted threshold (100), they are pursued, apprehended, and either arrested or killed by the field officers of the Crime Investigation Department of the Ministry of Welfare's Public Safety Bureau. Elite officers known as Inspectors research and evaluate crime scenes, including all personnel involved, with the assistance of Enforcers. Enforcers are latent criminals charged with protecting the Inspectors, adding their expertise and carrying out Inspectors' instructions. Both are equipped with personally activated hand-held weapons called "Dominators" whose integrated scanners provide the target's immediate Psycho-Pass. The gun-like weapon can only fire when approved by the Sibyl System and triggered by its owner. Inspectors and Enforcers work as a team, though Inspectors have jurisdiction to fire their Dominators on the Enforcers should they pose a danger to the public or the Inspectors themselves. An individual's Psycho-Pass is used in multiple ways, both professional and personal. It influences one's level of education, hobbies, future career and likelihood of promotion, as well as one's choice of friends or potential mate. Law enforcement uses the information to determine an individual's propensity towards criminal behavior with their weapons possessing hand-held scanners that enable them to see someone's current Psycho-Pass, which then sets their weapon to an appropriate level of discharge.
