The book looks both at what 'noise in human judgment' is, how it can be detected and how it can be reduced. Views Legal philosophy Sunstein is a proponent of judicial minimalism, arguing that judges should focus primarily on deciding the case at hand, and avoid making sweeping changes to the law or decisions that have broad-reaching effects. Some view him as liberal, despite Sunstein's public support for George W. Bush's judicial nominees Michael W. McConnell and John G. Roberts, as well as providing strongly maintained theoretical support for the death penalty. Conservative libertarian legal scholar Richard A. Epstein described Sunstein as "one of the more conservative players in the Obama administration." Much of his work also brings behavioral economics to bear on law, suggesting that the "rational actor" model will sometimes produce an inadequate understanding of how people will respond to legal intervention. Sunstein has collaborated with academics who have training in behavioral economics, most notably Daniel Kahneman, Richard Thaler, and Christine M. Jolls, to show how the theoretical assumptions of law and economics should be modified by new empirical findings about how people actually behave. According to Sunstein, the interpretation of federal law should be made not by judges but by the beliefs and commitments of the U.S. president and those around him. "There is no reason to believe that in the face of statutory ambiguity, the meaning of federal law should be settled by the inclinations and predispositions of federal judges. The outcome should instead depend on the commitments and beliefs of the President and those who operate under him," argued Sunstein. Sunstein (along with his coauthor Richard Thaler) has elaborated the theory of libertarian paternalism. In arguing for this theory, he counsels thinkers/academics/politicians to embrace the findings of behavioral economics as applied to law, maintaining freedom of choice while also steering peoples' decisions in directions that will make their lives go better. With Thaler, he coined the term "choice architect". Military commissions In 2002, at the height of controversy over Bush's creation of military commissions without Congressional approval, Sunstein stepped forward to insist, "Under existing law, President George W. Bush has the legal authority to use military commissions" and that "President Bush's choice stands on firm legal ground." Sunstein scorned as "ludicrous" an argument from law professor George P. Fletcher, who believed that the Supreme Court would find Bush's military commissions without any legal basis. In
