T-shaped expertise: rethinking interdisciplinarity in psychedelic research
Psychedelics June 28, 2026 Joost J. Breeksema, Ulf Bremberg, Jens H. van Dalfsen et al.
Psychedelic therapies face layered complexity from interactions between pharmacological and extra-pharmacological factors, and their embeddedness in societal, legal, and regulatory systems. This is compounded by epistemic fragmentation: dominant biomedical paradigms often clash with knowledge from social sciences, humanities, or Indigenous traditions. Though interdisciplinary engagement is increasingly recognized as necessary, existing calls rarely specify structural or pedagogical conditions for operationalizing it. Addressing these complexities requires moving beyond superficial collaboration; genuine interdisciplinary progress needs researchers capable of productive friction across epistemic cultures. The authors propose cultivating T-shaped competencies and intersectoral training as a structural response to these systemic challenges.
