Schooling the Supreme Court

Supreme Court Justices\u27 uniform professional backgrounds have drawn increasing criticism. Yet it is unclear how diverse professional training would affect the Court\u27s decisions. This Article offers the first empirical analysis of how Justices with diverse professional training vote: It examines a unique period when Justices with formal legal education sat with Justices who entered the profession by reading the law alone. The study finds that Justices\u27 levels of agreement and politically independent voting vary significantly according to their professional training. In cases which divided the Court, Justices who shared the benefit of formal legal education (1) voted together more often and (2) voted more independently of their appointing presidents\u27 ideologies than Justices without this background. These findings substantially qualify earlier views on the desirability of Justices without formal legal education. Diversity in professional training is consistent with calls for a more politically responsive Court. It does not support arguments for an optimally diverse group of decision makers, however, unless one is also willing to accept diminished political independence that has been shown to accompany diverse professional training
