vb. (present participle of dumb down English)
Wikipedia
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.
Philosophically, the term "dumbing down" is a relative definition, because what is considered dumbing down depends on the taste, value judgement, and intellectual level of the person involved in the matter. In Distinction: A Social Critique of the Judgement of Taste (1979), the sociologist Pierre Bourdieu (1930–2002) proposed that, in a society in which the cultural practices of the ruling class are rendered and established as the legitimate culture of that society, that action then devalues the cultural capital of the subordinate social classes, and thus limits their social mobility within their own society.
