Cass R. Sunstein
Also known as Cass Robert Sunstein
Behavioral economics and legal theory intersect to explain how subtle shifts in choices, policy design, and administrative decision-making impact everyday human lives. Cass R. Sunstein has shaped public understanding of choice architecture and regulatory policy through landmark publications such as Nudge: Improving Decisions About Health, Wealth and Happiness, co-authored with Richard H. Thaler. His interdisciplinary work explores how institutions can guide better decision-making without restricting individual freedom, bridging academic rigor and practical governance.
Career & Background
Born in September 1954 in Salem, Massachusetts, Sunstein attended Harvard University, where he served as an editor of the Harvard Lampoon. He built a distinguished academic career as a professor at the University of Chicago Law School from 1981 to 2008 before joining Harvard Law School, where he serves as the Robert Walmsley University Professor. At Harvard, Sunstein founded and directs the Program on Behavioral Economics and Public Policy, and co-directs the Initiative on Artificial Intelligence and the Law. From 2009 to 2012, he served as Administrator of the White House Office of Information and Regulatory Affairs in the Obama administration. In 2018, he received the Holberg Prize from Norway for his scholarship, and in 2020, the World Health Organization appointed him Chair of its technical advisory group on Behavioral Insights and Sciences for Health.
Writing Style & Themes
Sunstein's writing synthesizes constitutional law, administrative regulation, behavioral economics, and cognitive science into accessible, policy-relevant analysis. A primary theme throughout his scholarship is choice architecture—the concept that decision environments can be structured to encourage better choices regarding health, wealth, and welfare while preserving freedom of choice, an approach termed libertarian paternalism. His work also focuses on judicial minimalism, administrative cost-benefit analysis, regulatory efficiency, and the cognitive biases or systemic errors that degrade human judgment, including unwanted variability in decision-making.
