Scholars claim that futures and foresight science should overcome “confusion” regarding the definition of core concepts, for example, the scenario. Admittedly, defining scenario has been a challenge. Current practice, which results in repeated attempts to clarify said confusion with yet another new definition of scenario, has apparently not advanced the field. An alternative option is not to redefine scenario, but to, instead, create a shared definition composed of component parts of pre-existing definitions. The result is an operant or synthesized definition based on analysis of claims indicating what “a scenario is” and “scenarios are” in the literature on scenario planning. The authors find that scenarios have a temporal property rooted in the future and reference external forces in that context; scenarios should be possible and internally plausible while taking the proper form of a story or narrative description; and that scenarios exist in sets that are systematically prepared to co-exist as meaningful alternatives to one another. Despite claims to the contrary, the authors find that the academic community of futures and foresight science does not seem to suffer from so-called confusion over the definition of scenario, and, thus, it is time to sunset the use of claims to this end.
