Crime Coefficient
A number that decides whether you are a citizen or a threat before you ever choose to be one.
The Crime Coefficient is the numerical axis of the Psycho-Pass system in the Sibyl-governed world of Psycho-Pass. While the Hue (a shifting color that signals a person's mental drift toward criminality) is the more visceral, visual component, the Crime Coefficient is the cold, quantified score that tells an Inspector exactly how dangerous a citizen is *before* they pull a trigger. It is the number that turns a person into a risk assessment, and it is the number that the show's characters either obey, question, or ultimately try to shatter.
In practice, every citizen walks through life with this invisible tally updating in real time, monitored by the omnipresent Sibyl System. Inspectors carry Dominators that read a target's Coefficient and Hue simultaneously, granting them a legal and ethical framework for use of lethal force. The tension of the entire series hinges on whether a number can truly capture the moral weight of a human being—and whether a society that outsources judgment to an algorithm has traded freedom for a very comfortable, very quiet kind of safety.

Lore & Background
In the Sibyl System's architecture, the Crime Coefficient is not a static label but a continuously recalculated probability. It draws on biometric data, behavioral patterns, psychological profiling, and social context to project a person's likelihood of committing a crime within a given window. The number can rise or fall as a person's circumstances and mental state shift, which is why the Hue—the chromatic companion to the Coefficient—matters: a low number with a deepening red Hue is as alarming as a high number with a stable, pale tone. The system treats the two axes as complementary lenses on the same underlying question: *will this person hurt someone, and how soon?*
The Coefficient is what makes the Inspector-Enforcer pairing functionally necessary. An Inspector, whose own Psycho-Pass is clear, is legally authorized to fire a Dominator at a target whose Coefficient crosses a threshold. An Enforcer, by contrast, is someone whose own Coefficient is too high to hold Inspector status but whose skills are still useful; they operate in a legal grey zone, their Dominators restricted, their actions monitored. Kogami's position in the story is a living argument about the Coefficient's meaning: the system says he is a future criminal, and the system is, in a narrow predictive sense, correct—yet the *why* and the *who* behind his actions are things the number cannot express.
Philosophically, the Crime Coefficient sits at the intersection of determinism and free will. If Sibyl can calculate your future crime with high confidence, were you ever truly free to choose otherwise? The show never gives a clean answer. It shows citizens who are genuinely reformed and whose numbers drop, and it shows people whose numbers are low but whose hidden resentments simmer just below the threshold. The Coefficient is a powerful tool, the narrative argues, but it is a tool that measures the *shape* of a person's risk, not the *soul* of their choice.
In Their Own Story
Rain streaked the glass of the 14th-floor inspection office, each droplet catching the cold blue glow of the Sibyl terminal. Makishima sat perfectly still, hands folded, while the Dominator's scope painted a thin red line across his chest. The number on the display had been climbing for three weeks—quiet, steady, like a tide no one could see until the water was at the door. He watched the Inspector's eyes, young and uncertain, searching his face for the monster the number described. He gave her a small, almost kind smile. The Coefficient ticked up one more point. She hesitated. The rain kept falling, and the number kept counting, patient as arithmetic, indifferent as a verdict already written in a language no one in the room could read.
Reader's Guide
The Crime Coefficient is the philosophical spine of Psycho-Pass, and understanding it reframes every character decision in the series. The central question the show poses is deceptively simple: if a sufficiently advanced system can predict your crime with high accuracy, is punishing you in advance a form of justice or a form of tyranny?
The show argues both sides with unusual fairness. On one hand, the Coefficient has genuinely saved lives; citizens who would have been victims are protected before the harm occurs, and the Hue system gives people a visible, personal feedback loop that encourages self-correction. Akane Tsunemori's arc in Season 1 is essentially a journey from trusting the number to questioning it, and the show lets her doubt without mocking her.
On the other hand, the Coefficient reduces a person to a probability. Kogami's high number does not explain his grief, his loyalty, or the specific person he is willing to kill for. Makishima's entire project is an argument that the number is a cage: a society that pre-sorts its members by predicted risk has not eliminated crime, it has simply made dissent invisible and obedience the only path to a clear Hue. The show does not fully resolve the tension. It ends by suggesting that the Coefficient can be a useful signal but never a sufficient verdict—that the human act of choosing, flawed and unquantifiable, is precisely what a number cannot capture.
When you watch a Dominator lock onto a target and the Coefficient scroll across the optic, you are watching the show ask you to decide: do you trust the number, or do you trust the person behind it?
Did You Know?
- The Crime Coefficient and the Hue are two separate but linked readings; a person can have a relatively low Coefficient while their Hue deepens, signaling a slow psychological drift that the number alone would miss.
- Enforcers are citizens whose own Crime Coefficient is high enough to disqualify them from Inspector status, yet whose operational skills the system still values—making them a permanent, monitored underclass within the po
- The Coefficient is not a fixed score assigned at birth; it recalculates continuously as the Sibyl System ingests new behavioral and biometric data, meaning a person's 'criminality rating' can shift over hours or days.
- Makishima's rebellion in Season 1 is framed not as a desire to commit random violence but as an attempt to expose the Coefficient as a tool of social control that punishes thought and intent before any act is ever carrie
