Susan Greenhalgh, professor of anthropology at UC Irvine, has written a new book called Just One Child: Science and Policy in Deng’s China. The author argues that scientific policymaking by a team of aerospace engineers led directly to widespread social suffering while giving birth to a technoscientific state. Greenhalgh draws on 20 years of research into China’s population politics to explain how a nation of one billion decided to limit all couples to one child. The book has been called “remarkably well-researched and thoughtful” by Peter L. Galison, history of science professor at Harvard University. The book was published by University of California Press.
