 Integration of distinct disciplines may take various forms, depending on the object of integration: explanations, models, experimental methods, bodies of data, concepts, theoretical frameworks, instruments and tools, research infrastructures, etc. (Hacking 1992b; Rueger 2005; O’Malley 2013; Grantham 2004). It is commonly assumed that integration constitutes a standard of success of interdisciplinary endeavors (Holbrook 2013). However, this assumption has been challenged on the ground that interdisciplinary success can sometimes be achieved without integration of disciplines. Heterogenous actors can cooperate in interdisciplinary “trading zones” (Galison 1997) in which actors “hammer out a local coordination, despite vast global differences” (1997: 783). Case studies such as evolutionary game theory show that productive interdisciplinary interactions can develop while fields keep developing distinct concepts, methods, explanations, and ontologies (Grüne-Yanoff 2016).
