Today I’m talking with Gareth Thomas, a sociologist interested in medicine, disability, stigma, reproduction, and technology. His book, Down’s Syndrome Screening and Reproductive Politics: Care, Choice and Disability in the Prenatal Clinic, is an ethnography of Down’s syndrome screening in two UK clinics. In it, he identifies how and why screening is successfully routinised and how it is embroiled in both new and familiar debates surrounding pregnancy, ethics, choice, diagnosis, care, disability and parenthood.
