"A profoundly learned and humbling look at the wobbly foundation on which many of our most important public policies are built. Friedrich Hayek warned against the pretense of knowledge. Now Jim Manzi cautions against the abuse of social science." -David Frum, Newsweek/The Daily Beast
"More and more people are coming to realize the crucial role that trial and error play in cultural progress as well as in biological evolution. Jim Manzi's ingenious book not only explores where trial and error work, but where they are lacking - in government, for example, where failure is rarely punished." -Matt Ridley, The Rational Optimist
"In both the physical and social sciences, investigators must work overtime to reconcile general theories with stubborn facts. No one weaves these threads better than Jim Manzi does in his new tour-de-force, Uncontrolled." -Richard Epstein, University of Chicago
"Uncontrolled offers a very rare mix of philosophical depth, practical knowledge, and plain good sense. And thanks to Manzi's highly accessible writing style and ability to explain complicated concepts in plain English, the book is both a profound lesson in how the world works (and could work better), and a great read." -Yuval Levin, National Affairs
"Uncontrolled demonstrates the unparalleled strategic advantage from mobilizing first-rate analytical rigor and real life experimentation to drive superior decision making." -Nigel Morris, Capital One
