Volume 2 in this landmark 3-volume series The Anthropology of Obstetrics and Obstetricians: The Practice, Maintenance, and Reproduction of a Biomedical Profession looks at cognition, risk, and responsibility in obstetrics. This volume contains social science analyses of Swiss, Chilean, Mexican, US, Greek, and Irish obstetrics and obstetricians, particularly around their reasons for the overuse of cesareans; a chapter on "4 Stages of Cognition" and a condition called "Substage," which describes how these concepts apply to obstetricians; and a chapter on why obstetricians fear home birth. This book is a must-read for students, social scientists, and all maternity care practitioners who seek to understand obstetricians' differing ideologies and motives for practicing as they do. An excerpt from Vania Smith-Oka and Lydia Dixon's chapter: For systemic changes to occur, we must understand doctors' decision-making rationales and take their fear-based perspectives about risk and responsibility into account, while also paying attention to the concerns raised by scholars and activists.
