[Inter- and Transdisciplinarity as a Normative Dynamic: Challenges and Opportunities for Political Science].

Inter- and transdisciplinarity (ITD) has been part of political science for quite some time now, but although political science regularly deals with its self-understanding, the consequences for research and researchers of ITD have not yet been systematically considered. To stimulate this debate, we conceptualize ITD as a spectrum of knowledge integration, application, and participation. We use International Relations norm research as a theoretical framework to describe, analyze, and reflect on ITD as a normative dynamic. Autoethnographically and through participatory observation, we examine ITD as a normative dynamic, with insights from three research projects in the field of sustainability. Specifically, we ask what implications ITD has for researchers and research in political science. As a result, we find that ITD offers both opportunities and challenges. In the context of knowledge integration, we discuss the importance of the participation of political science in major societal issues in contrast to ITD's preferences for a particular understanding of knowledge and research. We reflect on ITD's application bias in terms of problem-solving opportunities and output orientation. In addition, we consider the participation postulate of ITD and weigh potential democratizing effects against the conditions under which these might be realized. Finally, we address where further research seems useful to continue reflection on ITD.
