Exploring Interdisciplinarity and Transdisciplinarity as Knowledge Regimes: A Heuristic Tool for Disentangling Understandings in Academia and Policy

This paper presents a heuristic tool aiming at bringing the multiple dimensions of interdisciplinarity (ID) and transdisciplinarity (TD) into direct conversation for researchers, funders, and policymakers. These societal actors have divergent conceptions, definitions, and practices of ID and TD that can be fruitfully put into dialogue to prosecute successful projects and programs. We anchor our study on the concept of "knowledge regime" and its three components (ideologies and myths, shared beliefs and practices, and imaginaries and values) to develop a comprehensive view of the heterogeneous understandings of ID and TD that goes beyond the cognitive dimension. Founded on a qualitative methodology, we designed a heuristic tool to disentangle this heterogeneity and bridge the different understandings in a comparable way. Through a semi-structured dialogue, users of the tool discuss ten questions that guide reflections on understandings of ID and TD used in projects, funding programs, and policy processes and their implications to reveal differences and increase mutual understanding. The findings offer details on the tool and systematize insights from those users who tested it in different contexts. We conclude by discussing the contribution this heuristic tool makes when considering ID and TD as knowledge regimes in the scientific and policy domains.
