Changes

|Prehistory=There has been a long tradition of confusing different stances that a community can take towards a theory. [[Thomas Kuhn]], for example, used a number of equally vague words, including ''universally received'', ''embraced'', ''acknowledged'', and ''committed'' to describe the status of theories within scientific communities. Kuhn's theory of scientific change dealt with regarded the units of scientific change to be frameworks that he referred to as ''paradigms'' [[CiteRef::Kuhn (1962)]] or , a term which he himself later as confessed he had used in several different senses. [[CiteRef::Kuhn(1977)|pp.293-319]] He clarified his theory by introducing the concept of ''disciplinary matricesmatricies'', defined as those shared elements that account for the relatively unproblematic professional communication and relative unanimity of professional judgment within a scientific community.  These include shared symbolic generalizations, models, and exemplars [[CiteRef::Kuhn (1977)
