The Racial Cage is the result of a slow conversation about injustice, racism, health, and science that unfolded during the Covid-19 pandemic. Spurred by an endeavor we were involved in at the Sydney Centre for Healthy Societies at the University of Sydney, we gathered under the research theme “Race, Ethnicity, and the Biohumanities” to consider where it might conceptually take us and what political urgencies it might encompass. We have been both troubled and tantalized by the “biohumanities” part of this theme, but it proved productive for our conversations; it invited us to also open up that other concept in this theme: “race.” The conversations that followed were particularly interesting given our similarities and differences: Each of us has been working independently on issues of race and drawing on STS scholarship in our ongoing research. We brought into our conversations different takes on race and ethnicity and different fields of research, from bioscience research to pharmaceuticals and medicine, from forensics to the governance of life, and from data to DNA. We brought our different domains of research and teaching to our effort to think and rethink the bio and the human, taking time to query each other’s objects of study, methodological orientations, and epistemological commitments. We brought literary and interpretive as well as social science sensibilities to bear on our understandings of race, difference, and power, drawing insights from while working alongside the more established field of the medical humanities. As such, our conversations were always open-ended, never settling, and always leaving us with more questions.
