Dumbing down is the deliberate oversimplification of intellectual content within education, literature, cinema, news, video games and culture in order to relate to those unable to assimilate more sophisticated information. The term "dumbing down" originated in 1933 as movie-business slang, used by motion picture screenplay writers, meaning: "[to] revise so as to appeal to those of little education or intelligence". Dumbing-down varies according to subject matter along with the reasons for lowering the intellect of the subject or topic. It often involves diminishment of critical thought involving the undermining of intellectual standards within language and learning; thus trivializing meaningful information, culture, and academic standards, as is the case of popular culture.
