With some regularity I read papers from HCI, trying to identify or define paradigms within the discipline. Invariably the introduction of the term paradigm is enfolded in cautionary remarks about the use of the term, typically with references to Thomas Kuhn or Imre Lakatos. However, it never gets clear to me which debate these authors are trying to soothe Are these authors differentiating against light uses of the word paradigm (as in experimental paradigm) or to particularly heavy ones?
