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".
