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".[1] Dumbing-down varies according to subject matter, and usually involves the diminishment of critical thought by undermining standard language and learning standards, thus trivializing academic standards, culture, and meaningful information, as in the case of popular culture.
