Pre-crime

Pre-crime is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pre-crime rather than just read about it. In short: Pre-crime, also spelled precrime, is the idea that the occurrence of a crime can be anticipated before it happens. The term was coined by science fiction author Philip K.

Key takeaways

  • Pre-crime belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pre-crime to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pre-crime from memory before moving on to harder problems.

Reference excerpt

Pre-crime, also spelled precrime, is the idea that the occurrence of a crime can be anticipated before it happens. The term was coined by science fiction author Philip K. Dick, and is increasingly used in academic literature to describe and criticise the tendency in criminal justice systems to focus on crimes not yet committed. Pre-crime intervenes to punish, disrupt, incapacitate, or restrict those deemed to embody future crime threats. As a term, it embodies a temporal paradox, suggesting both that a crime has not yet occurred and that it is a foregone conclusion.

Origins of the concept George Orwell introduced a similar concept in his 1949 novel Nineteen Eighty-Four using the term "thoughtcrime" to describe illegal thoughts that held banned opinions about the ruling government or intentions to act against it. A large part of how it differs from pre-crime is in its absolute prohibition of anti-authority ideas and emotions, regardless of the consideration of any physical revolutionary acts; however, Orwell was describing behaviour he saw in governments of his day as well as extrapolating on that behaviour, and so his ideas were themselves rooted in real political history and current events. In Philip K. Dick's 1956 science fiction short story "The Minority Report", PreCrime is the name of a criminal justice agency, the task of which is to identify and eliminate persons who will commit crimes in the future. The agency's work is based on the existence of "precog mutants", a trio of "vegetable-like" humans whose "every incoherent utterance" is analyzed by a punch card computer. As Anderton, the chief of the PreCrime agency, explains the advantages of this procedure, "in our society we have no major crimes ... but we do have a detention camp full of would-be criminals". He cautions about the basic legal drawback to pre-crime methodology, "We're taking in individuals who have broken no law." The concept was brought to wider public attention by Steven Spielberg's 2002 film Minority Report, loosely adapted from the story. The Japanese cyberpunk anime television series Psycho-Pass (2012–2013) had a similar concept.

In criminological theory Pre-crime in criminology dates back to the positivist school in the late 19th century, especially to Cesare Lombroso's idea that there are "born criminals", who can be recognized, even before they have committed any crime, on the basis of certain physical characteristics. Biological, psychological and sociological forms of criminological positivisms informed criminal policy in the early 20th century. For born criminals, criminal psychopaths, and dangerous habitual offenders, eliminatory penalties such as capital punishment, indefinite confinement, and castration were seen as appropriate. Similar ideas were advocated by the social defense movement and into the 1990s by what is seen and criticized as an emerging "new criminology", or "actuary justice". The new "pre-crime" or "security society" requires a radically new criminology.

Testing for pre-delinquency Richard Nixon's psychiatrist, Arnold Hutschnecker, suggested in a memorandum to the president to run mass tests of "pre-delinquency" and put those juveniles in "camps". Hutschnecker, a refugee from Nazi Germany and a vocal critic of Adolf Hitler at the time of his exodus, rejected the interpretation of the memorandum that he advocated concentration camps, "It was the term 'camp' that was distorted. My use of it dates back to when I came to the United States in 1936 and spent the summer as a doctor in a children's camp. It was that experience and the pastoral setting, as well as the activities, that prompted my use of the word 'camp.'"

In criminal justice practice

The frontline of a modern criminal justice system is increasingly preoccupied with anticipating threats, and is the antithesis of the traditional criminal justice system's focus on past crimes. Traditionally, criminal justice and punishment presuppose evidence of a crime being committed. This time-honored principle is violated once punishment is meted out "for crimes never committed". An example of this trend in the first decade of the 21st century is nachträgliche Sicherungsverwahrung (retrospective security detention), which became an option in German criminal law in 2004. This "measure of security" can be decided upon at the end of a prison sentence on a purely predictive basis. In France, a similarly predictive measure was introduced in 2008 as rétention de sûreté (security detention). The German measure was viewed as violating the European Convention on Human Rights by the European Court of Human Rights in 2009. As of 2014, the German law was still partly active in Germany and new legislation was planned for continuing the pre-crime law under the new name Therapieunterbringung (detention for therapy). A similar provision for indefinite administrative detention was found within the judicial system of Finland but was not enforced after the mid-1970s. Pre-crime is most obvious and advanced in the context of counter-terrorism, although it is argued that far from countering terrorism, pre-crime produces the futures it purports to prevent. In 2020, the Tampa Bay Times compared the Pasco County Sheriff's Office pre-crime detection program to the film Minority Report, citing pervasive monitoring of suspects and repeated visits to their homes, schools, and places of employment. In 2025, The Guardian reported that the UK Ministry of Justice was developing a "murder prediction system". The existence of the project was discovered by the pressure group Statewatch, and some of its workings were uncovered through documents obtained by Freedom of Information requests. Statewatch stated that The Homicide Prediction Project uses police and government data to profile people with the aim of 'predicting' who is "at risk" of committing murder in future. The project began in January 2023 under Prime Minister Rishi Sunak.

Worked examples

Example 1 — a first encounter with Pre-crime

Start with the simplest possible case. Write down what Pre-crime claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pre-crime before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pre-crime ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pre-crime

In research
Pre-crime appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pre-crime in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pre-crime is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crime prevention, Criminal law, Criminology, so understanding it makes those chapters shorter.
In everyday life
Look for Pre-crime outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
