Posner attended Yale University, earning B.A. and M.A. degrees in philosophy, summa cum laude. He then received his J.D. degree, magna cum laude, from Harvard Law School in 1991. He clerked for Judge Stephen F. Williams of the D.C. Circuit. == Career ==

Posner started his teaching career at the University of Pennsylvania Law School from 1993 to 1998. In 1998, Posner joined the University of Chicago Law School, where he is now the Kirkland and Ellis Distinguished Service Professor of Law and Esther Kane Research Chair. He has also been a visiting professor at Columbia Law School and NYU School of Law. From 1998 to 2011, he was an editor of The Journal of Legal Studies. He is the author or co-author of many books and articles, on subjects including international law, cost-benefit analysis, and constitutional law. At Chicago he teaches Antitrust, Contracts, Public International Law, and Financial Regulation, amongst other courses. Beginning in 2022, Posner began service as Counsel to the Assistant Attorney General for Antitrust at the United States Department of Justice. == Work ==

Posner's published books have ranged over topics including international law, foreign relations law, contracts, and game theory and the law. In 2005, Posner posted about the trial of the deposed Iraqi President Saddam Hussein. In June 2013, Posner and Jameel Jaffer, fellow at the Open Society Foundations, participated in The New York Times Room for Debate series. In 2015, Posner co-founded the book review The New Rambler. Posner's position concerning the heightened standing of the executive branch of government was criticized in 2016 by Jeremy Waldron in his book Political Political Theory as not sufficiently sensitive to issue of legislative priorities. In 2018, Posner co-wrote an article advocating a system of market-oriented, privately sponsored work visas as a supplement to U.S. immigration policy. Law and Emotions Posner has argued for increased attention towards the role of emotions in legal theory. In 2001, Posner's Law and the Emotions detailed the implications of emotional decision making in legal decisions and procedures, as well as in rational choice theory. In particular, he argues that the American legal system's deeply rooted basis in cognitive science often eschews, or has yet to develop, significant acknowledgement of the role emotions play in criminology and contract theory. For example, a person who commits a criminal act while in an emotional state may receive a harsher or lighter punishment depending on whether they were motivated by hatred or shame. Indeed, consideration of the emotional component is often systemic or even codified, but any analysis thereof has been historically ignored. Rational choice theory Posner claims that a person who is in an emotional state rarely acts on reflex, instead remaining in control of their actions. Though the actions of an individual may be colored by a changing set of values, abilities, and preferences particular to their emotional state, these actions nonetheless remain guided in a procedural manner. Therefore, the mere observation that an individual's preferences are usually consistent while calm does not invalidate the role of rationality throughout the more temporary preferences of each emotional state. In other words, while emotional preferences modify the action tendency of any set of possible behaviors, the cognitive decision to commit to an action is nevertheless bound by reason. == Selected bibliography ==
