{"pk":29803,"title":"Requisite Variety, Cognition, and Scientific Change","subtitle":null,"abstract":"Multiple theories of scientific change have been prominently\npromulgated since Kuhn. A quasi-discipline “Scientonomy” has\neven been proposed to formalize these theories. The cybernetics\nprinciple known as “The Law of Requisite Variety (LRV)” when\ncombined with cognitive science insights regarding categorization\nand its ilk can be used to chart one such formalism. LRV holds that\ncontrol/prediction can only be assured when the internal\ncomplexity of a system matches the external complexity it\nconfronts The key indicator of an activity directed at scientific\nchange comes from examinations of the models which scientists\ndeploy in attempting to link pre-existing explanations with new\nproblems to be explained. Normal science is a reductive activity –\nlimiting the variety encountered. Innovative science is the process\nof expanding such variety, and scientific change is what happens\nwhen the innovative crosses the threshold for normal.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"scientific change; requisite variety; cybernetics"},{"word":"scientonomy"}],"section":"Poster Session 2","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7s78j8bz","frozenauthors":[{"first_name":"Michael","middle_name":"","last_name":"Lissack","name_suffix":"","institution":"University, Shanghai, China","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29803/galley/19657/download/"}]}
