Bourgeois pseudoscience (Буржуазная лженаука) was a term of condemnation in the Soviet Union for certain scientific disciplines that were deemed unacceptable from an ideological point of view. At various times pronounced "bourgeois pseudosciences" were: genetics (see Eugenics, Racial hygiene, Scientific racism, also Lysenkoism), cybernetics, sociology, semiotics, and comparative linguistics (see Japhetic theory). This attitude was most prevalent during the rule of Joseph Stalin. Other disciplines were declared "bourgeois pseudosciences" in the People's Republic of China.
