ABSTRACT
This essay discusses the relationship between social theory and science diplomacy for both academic and policy application. This discussion is based on workpackage 2 Power with Science Diplomacy of H2020 Inventing a shared Science Diplomacy for Europe (InsSciDE) and consortium-wide discussions. The outcome of the discussions on theory of science diplomacy is that it is unfeasible to develop one theory of science diplomacy. Science diplomacy practice is rich and wide-ranging. Science diplomacy as a concept continues to be contested and there is no consensus on a definition, which makes for dynamic research and debate. The conceptual instability of science diplomacy complicates defining it. After defining science diplomacy, it remains unclear what about science diplomacy to theorize. Ideal types of science diplomacy practices address the definitional challenge for the time being and allow theorizing which brings order to rich empirical material and links science diplomacy practices to diplomacy analytically rather than normatively. Looking at science diplomacy as an independent, intermediary, or dependent variable contributes to theorizing it.
