Dumbing down is the deliberate oversimplification of intellectual content in education, literature, cinema, news, video games, and culture. Originating in 1933, the term "dumbing down" was movie-business slang, used by screenplay writers, meaning: "[to] revise so as to appeal to those of little education or intelligence".

In Dumbing Us Down: The Hidden Curriculum of Compulsory Schooling (1991, 2002), John Taylor Gatto presented speeches and essays, including "The Psychopathic School", his acceptance speech for the 1990 New York City Teacher of the Year award, and "The Seven-Lesson Schoolteacher", his acceptance speech upon being named as the New York State Teacher of the Year for 1991. Gatto writes that while he was hired to teach English and literature, he came to believe he was employed as part of a social engineering project. The "seven lessons" at the foundation of schooling were never explicitly stated, Gatto writes, but included teaching students that their self-worth depended on outside evaluation, that they were constantly ranked and supervised, and that they had no opportunities for privacy or solitude. Gatto speculated:
