At a moment when both think tanks and experts are being questioned, significant policy and technology disruptions have called into question the value and efficacy of policy advice. Within that context, Dr. McGann launched this book to examine the future of think tanks and policy advice around the world with a series of authoritative reflections written by the presidents of some of the leading think tanks in the United States. The book explores the challenges think tanks face today in an information rich and highly competitive operating environment that includes: the impact of technology, big data and artificial intelligence, competition from advocacy groups and public relations firms, increased polarization of politics and major changes in how think tanks are funded.
