Interdisciplinarity prides itself to be a mode of research and teaching that is open to a diversity of insights, people and disciplines. Indeed, the key of interdisciplinarity (and transdisciplinarity likewise) is the integration of different perspectives. However, it is illusory to expect interdisciplinarity not to be subject to the same positionality as other modes of science or knowledge. Indeed, not recognizing this might lead to an epistemic form of ‘color-blindness’ that can be rather harmful. In addition, interdisciplinary education and research appears not to be attractive to many first generation academics for several reasons. This lecture will approach the challenge of diversity to interdisciplinarity as both an important conceptual topic as well as an urgent practical question: how can we ensure that interdisciplinary education and research is inclusive as we claim it to be?
