This volume includes chapters from an exciting group of scholars at the cutting edge of their fields to present a multi-disciplinary look at how international law shapes behavior. Contributors present overviews of the progress established fields have made in analyzing questions of interest, as well as speculations on the questions or insights that emerging methods might raise. In some chapters, there is a focus on how a particular method might raise or help answer questions, while others focus on a particular international law topic by drawing from a variety of fields through a multi-method approach to highlight how these fields may come together in a single project. Still others use behavioral insights as a form of critique to highlight the blind spots and related mistakes in more traditional analyses of the law. Throughout this volume, authors present creative, insightful, challenges to traditional international law scholarship.

One of the most noted developments in international law over the past twenty years is the proliferation of international courts and tribunals. They decide who has the right to exploit natural resources, define the scope of human rights, delimit international boundaries and determine when the use of force is prohibited. As the number and influence of international courts grow, so too do challenges to their legitimacy. This volume provides new interdisciplinary insights into international courts' legitimacy: what drives and undermines the legitimacy of these bodies? How do drivers change depending on the court concerned? What is the link between legitimacy, democracy, effectiveness and justice? Top international experts analyse legitimacy for specific international courts, as well as the links between legitimacy and cross-cutting themes. Failure to understand and respond to legitimacy concerns can endanger both the courts and the law they interpret and apply.
