"This may be the most important book to come out of President Obama's first term. Contrary to conservative perception, the administration, guided by Cass Sunstein, launched a brilliant effort to simplify and reduce regulations. Sunstein found ingenious ways to protect citizens and nudge corporate behavior while maximizing freedom and business opportunity. Simpler is a fascinating guide to how behavioral economics is improving government, and none too soon."

"Everyone complains that government regulations are often dumb, but how could you make them smarter? Here's a guidebook by someone who did it. It should be read by everyone who sets policies for government, nonprofits, education, or business."

"Tucked away from the sound and fury of politics, there is the quiet world of policy making. This fantastic book, from a magnificent scholar turned a master of this world, restored my faith in what governments really do, and more importantly in what a smart government could do to help citizens live better, more fulfilled lives."

"Cass Sunstein: scholar, public servant, choice architect. This lays out a new vision for how research from academics and attention from the public can be used to make regulations and government work better and simpler—to protect the public at the lowest possible cost and hassle. No wonder Glenn Beck said Sunstein was the most dangerous man in America."

"We typically don't associate the idea of simple systems with government and large corporations. But in this fine book, Sunstein provides a glimpse into how we can tame the complexity beast and why it is important, even necessary if we want to improve our collective welfare."

"Federal regulations determine the quality of the air we breathe and water we drink, the safety of our workplaces, the kinds of cars we can buy, and much more. In this book, Cass Sunstein shows how he helped President Obama use the smartest academic ideas to undertake the most important reform of our regulatory system in more than three decades. This revolution in regulation relies on using evidence, rather than ideology, to guide regulatory decisions and by making regulations simpler and easier to understand. Simple is a must (and fun) read for anyone who wants a deeper understanding of how government—and the people in it—are using the insights from the seminal research by Sunstein and others to make our lives healthier, safer, and more prosperous."

"Sunstein’s firsthand knowledge and distinct humor give his account a real dynamism."

"[Simpler is] ...a lucid, engaging treatment of behavioral economics that sees a role for the state in nudging humans towards rationality and responsibility. The result is a forthright, compelling vision of technocratic government that's both efficient and humane."

“A remarkably fun, engaging read.
