In light of the many excellent interdisciplinary sessions, this year’s Adjudication Committee decided to also make an Honorable mention for the session Wingspread@30: Birth and development of the endocrine hypothesis. This session’s participants were Mark Barrow, Jean-Paul Gaudillière, Nathalie Jas, Sheldon Krimsky, Maël Montévil, Marsha Richmond, Carlos Sonnenschein, and Ana Soto.

We are pleased to announce that the recipient of the 2021 Interdisciplinary Organized Session Prize was the session “Your genitals don’t lie!” An escorted encounter with the history and philosophy of phallic and cervical measuring. The participants of the winning session were Rebecca Jackson, Kärin Nickelsen, Jutta Schickore, Caterina Schürch, and Merlin Wassermann.

Exploring the historical, philosophical, and social dimensions of phallometry and cervimetry, this session embodied the ISHPSSB ideal of integrative, dialogic, critical, cohesive, and convivial interdisciplinarity. Representing innovation in our pandemic moment of remote collaboration and presentation, the session set a new bar in the delivery of scholarly interdisciplinary presentations at ISHPSSB, featuring a pre-recorded presentation of a tightly integrated and highly structured dialogue among disciplinary approaches and historical case studies, centrally featuring the work of two junior researchers, interlaced with commentary by more senior scholars. This structure continued into the open live discussion period, with participants modeling and provoking constructive, lively, and inclusive interdisciplinary discussion.
