Cultural Diversity and the Interdisciplinarity of Research Outputs: Evidence from UK Research Council Funded Projects

Do culturally diverse research teams produce more interdisciplinary science? The assumption is intuitively compelling: researchers from different cultural backgrounds may bring distinct perspectives, knowledge and ways of framing problems. Yet diversity may create interdisciplinary potential without necessarily producing integrated outputs. This study examines that relationship across 2,795 UK Research Council-funded projects, linking project-team records with OpenAlex publications and using distance-sensitive measures of inferred country-of-origin diversity and output interdisciplinarity.

The findings challenge simple expectations. Once investigators’ prior interdisciplinary publication profiles and project characteristics are considered, cultural diversity alone does not reliably predict more interdisciplinary outputs. Prior interdisciplinary orientation is instead the strongest measured predictor, indicating substantial continuity in teams’ capacity to work across disciplinary boundaries. For research funders, the implication is not to retreat from diversity, which has independent equity and representation rationales, but to invest in the time, leadership, coordination and support needed to translate heterogeneous perspectives into integrated research.
