Bourgeois pseudoscience (Russian: буржуазная лженаука, burzhuaznaya lzhenauka) was a term of condemnation in the Soviet Union for certain scientific disciplines that were deemed unacceptable from an ideological point of view due to their incompatibility with Marxism–Leninism. At various times pronounced "bourgeois pseudosciences" were: Mendelian genetics, cybernetics (artificial intelligence), quantum physics, theory of relativity,, geopolitics, sociology and particular directions in comparative linguistics (the now-debunked Japhetic theory of Nikolay Yakovlevich Marr, which was also refuted by Joseph Stalin in "Marxism and Problems of Linguistics"). 
The term was not used by Stalin himself, who rejected the notion that all sciences must have a class nature. Stalin removed all mention of “bourgeois biology” from Trofim Lysenko’s report, The State of Biology in the Soviet Union, and in the margin next to the statement that “any science is based on class” Stalin wrote, “Ha-ha-ha!! And what about mathematics? Or Darwinism?” The term or its synonyms was used in the 1951 and 1954 editions of the Short Philosophical Dictionary: "Cybernetic is a reactionary pseudoscience originated in the United States... A form of modern mechanicism.", "Eugenics is a bourgeois pseudoscience", "Weismannism-Morganism - bourgeois pseudoscience, designed to justify capitalism". Today, most scholars agree in characterizing eugenics as rooted in pseudoscience, albeit without the "bourgeois" qualifier.
Psychology was declared a "bourgeois pseudoscience" in the People's Republic of China during the Cultural Revolution (1966–1976). Furthermore, sociology was banned there in 1952, and it remained banned until the late 1970s.
