The past decade has seen a return of interest in empirical research within the U.S. legal academy, hearkening back to a similar empirical turn during the ascendancy of Legal Realism in the New Deal era. However, the current revival of legal empiricism has emerged against the backdrop of several well-established traditions of empirical socio-legal research both in the interdisciplinary law-and-society movement and in the social science disciplines themselves. This article examines two of the most prominent manifestations of the "new" legal empiricism, Empirical Legal Studies and New Legal Realism, and it situates them in the pre-existing socio-legal terrain. The analysis concludes by considering different possible futures for empirical law studies.
