1. Since the late 1960s, the word paradigm (IPA: /ˈpærədaɪm/) has referred to a thought pattern in any scientific discipline or other epistemological context. Initially the word was specific to grammar: the 1900 Merriam-Webster dictionary defines its technical use only in the context of grammar or, in rhetoric, as a term for an illustrative parable or fable. In linguistics, Ferdinand de Saussure used paradigm to refer to a class of elements with similarities.
2. Within science, researchers tend to ignore findings that may threaten an existing paradigm, or the conception of a new and competing paradigm.
