Cass Sunstein’s new book is out.  In it, the eminent legal scholar and best-selling co-author of Nudge (2008), breaks new ground with a deep yet highly readable investigation into the ethical issues surrounding nudges, choice architecture, and mandates, addressing such issues as welfare, autonomy, self-government, dignity, manipulation, and the constraints and responsibilities of an ethical state.

At this fascinating time when the social sciences are playing a more important role in both the defense and policy-making communities, it is worthwhile to consider some of the opportunities and challenges at the heart of this effort.
