There are two kinds of knowledge law school teaches: legal rules on the one hand and tools for thinking about legal problems on the other. Although the tools are far more interesting and useful than the rules, they tend to be neglected in favor of other aspects of the curriculum. In The Legal Analyst, Ward Farnsworth brings together in one place all of the most powerful of those tools for thinking about law. From classic ideas in game theory such as the Prisoner's Dilemma and the Stag Hunt to psychological principles such as hindsight bias and framing effects, from ideas in jurisprudence such as the slippery slope to more than two dozen other such principles, Farnsworth's guide leads readers through the fascinating world of legal thought.
