Editing The Minority Report (section)

===Majority and minority reports===
Each of the three precogs generates its own report or prediction.  
The reports of all the precogs are analyzed by a computer and, if these reports differ from one another, the computer identifies the two reports with the greatest overlap and produces a "majority report", taking this as the accurate prediction of the future. But the existence of majority reports implies the existence of a "minority report".  In the story, Precrime Police Commissioner John A. Anderton believes that the prediction that he will commit a murder has been generated as a majority report. He sets out to find the minority report, which would give him an alternate future.

However, as Anderton finds out, sometimes all three reports differ quite significantly, and there may be no majority report, even though two reports may have had enough in common for the computer to link them as such. In the storyline, all of the reports about Anderton differ because they predict events occurring sequentially, and thus each is a minority report. Anderton's situation is explained as unique, because he, as Police Commissioner, received notice of the precogs' predictions, allowing him to change his mind and invalidate earlier precog predictions.
