P: Positivist Criminology to Punishment

Core idea

The "P" cluster is the topic where criminology stops being moral philosophy and tries to become a science of cause and consequence. Positivism is the founding move — borrowing the methodology of the natural sciences to study crime as an effect of objective forces rather than a moral choice. Once you accept that frame, two practical questions follow: what do we do with offenders, and what kind of society is doing the doing. Prisons and imprisonment answer the first; postmodernity reframes the second, asking whether our era of selective enforcement and disproportionate sentencing has slipped its modern moorings. Property crime is the statistical bulk these institutions actually process, and punishment is the umbrella concept that organises every justification a state ever offers for inflicting harm in its own name.

Together these five concepts let you ask: by what method do we know crime, against what backdrop are we managing it, in what institutions are we containing it, what crimes are we mostly containing, and on what grounds is any of this justified?

Why it matters

Mental model

The five concepts are not independent — they form a causal sequence in the historical emergence of modern crime control.

Positivist criminology

Auguste Comte coined "positive philosophy" in the early 1800s to mean knowledge based on observation and demonstrable fact, not opinion or speculation. Applied to society, the move was radical: humans, like falling stones, must be subject to discoverable laws of cause and effect. The Belgian statistician Adolphe Quételet showed it could be done empirically — crime rates held remarkably steady year on year, suggesting that what looks like free-willed criminality is actually a population-level regularity tied to age, education, and income.

The Italian physician Cesare Lombroso then narrowed the project into biological positivism. By cataloguing the physical features of convicted felons he claimed to have identified the "born criminal" — a type marked by inherited atavistic traits. Lombroso coined the term criminology for this enterprise. The biological programme was empirically embarrassing in its specifics but conceptually durable: today's risk-factor research that hunts statistical correlates of offending in big datasets is Lombroso's grandchild. The contemporary critique — articulated by labelling theorists like Becker and revived by cultural criminology — is that crime is not a natural fact awaiting causal explanation but a social construction that emerges through interpretation. Jock Young calls statistically driven positivism "voodoo criminology" for the way it dresses interpretive choices in the costume of objective science.

Postmodernity and postmodernism

"Postmodern" carries two distinct meanings that need to be kept apart. Postmodernity names a type of society — service economies replacing industrial ones, fragmented identities replacing mass solidarities, hyper-differentiated lifestyles replacing fixed hierarchies. Postmodernism names a way of seeing — a movement that challenges the idea of neutral scientific knowledge and insists that subjugated perspectives are equally valid accounts of the social world.

Criminological debates split along the same line. One strand asks whether criminal-justice systems have abandoned modern goals of proportionate sentencing in favour of selective, even arbitrary enforcement, with petty offenders disproportionately punished and welfare spending displaced by penal spending. The other strand, articulated by writers like Biko Agozino, asks the discipline to decolonise — to recognise that "neutral" criminological theory was built on European colonial foundations and to expose the wider harms baked into the global order.

Prisons and imprisonment

Before the seventeenth century, prisons mostly held people awaiting trial. Punishment itself was inflicted on the body — whipping, branding, mutilation, public execution. Imprisonment as the dominant form of punishment is a modern invention. Foucault's Discipline and Punish (1977) gives four reasons it took hold: corporal spectacle failed as deterrence, a new humanitarian sensibility recoiled from cruelty, the Enlightenment elevated liberty so loss of liberty became a meaningful sanction, and a new scientific view of deviance imagined offenders could be corrected rather than just hurt.

Two centuries of reforming optimism designed institutions of separation and discipline. From roughly the 1970s onward that optimism collapsed. Rehabilitation seemed to fail (recidivism rates stayed stubborn), prison populations soared even as recorded crime fell, and privatisation introduced profit incentives that critics see as fundamentally at odds with the duty of care. The UK adult prison population passed 80,000 in 2006 — the highest rate of incarceration since 1870s records began. The United States, with under 5% of the world's population, holds roughly 25% of the world's prisoners.

Property crime

Property crime accounts for around 80% of recorded offences — burglary, motor vehicle theft, criminal damage, robbery, vandalism. The post-war upward trend in recorded crime is overwhelmingly a property-crime trend, driven by the explosion in portable high-value consumer goods (electronics, cars, jewellery) that routine-activity theorists call "suitable targets". Police time, court time, prison time, probation time — all follow the statistical centre of gravity. The private security industry exists primarily to defend property.

Cultural criminologists add a corrective: not every property crime is materially motivated. Arson, graffiti, and joyriding offer expressive and emotional satisfactions that the standard economic model misses entirely.

Punishment

Punishment is a universal feature of human societies, but every formal justification for it collapses into one of three categories.

• Deterrence assumes a rational actor weighing costs against benefits. Make the costs sufficiently severe and certain and crime becomes irrational. The evidence for actual deterrence is weak — recidivism rates suggest that the experience of punishment does little to disincline future offending.
• Incapacitation sidesteps deterrence by physically preventing further crime — imprisonment, electronic tagging, chemical castration, capital punishment at the limit. The justification is consequentialist and intuitive but expensive at scale.
• Retribution abandons forward-looking calculation entirely. The offender has caused suffering and should be made to suffer in return — "just deserts". Durkheim added a sociological gloss: retributive ritual reinforces collective norms and rebinds the community. Recent decades have seen a measurable political shift toward retributive logic at the expense of rehabilitation.

Practical application

When a politician, judge, or journalist defends a sentence, the question to ask is which justification they are leaning on — and whether it survives empirical scrutiny.

Example

A city council debates a proposal to introduce indefinite minimum sentences for car theft after a spike in vehicle break-ins. The councillor moving the motion frames it as deterrence: "If they know they'll get a real sentence, they'll think twice." A criminologist on the public committee notices three things at once.

First, the spike is a property-crime phenomenon driven by routine-activity changes (a new commuter rail station has flooded one neighbourhood with parked cars), not a deterrent failure. Second, the proposal is incapacitation wearing a deterrence costume — its real promise is that during the long sentence the offender literally cannot steal cars, which is true but expensive. Third, the population that will fill the new prison cells under this policy will not be a representative cross-section of car thieves but the subset who lack the resources to evade detection, plead down, or hire counsel. The criminologist's intervention isn't to argue against punishment but to name which justification is in play and force the council to defend the policy on the terms it is actually operating under. Two of the three justifications collapse on inspection; only retribution remains, and a council that wants to vote for it should at least say so.
