Hofstra Law Review

Abstract

In the last decade, the Supreme Court relied on scientific findings presented in amicus curiae briefs filed by various medical and psychological organizations and health professionals in three juvenile justice cases, Roper v. Simmons, Graham v. Florida, and Miller v. Alabama. Theresearch showed that the structure and function of adolescent brains are distinct from those of adults, which supports the position that adolescents, as a class, are generally immature in three separate, but related, ways. First, adolescents are more likely to engage in risky behavior than adults; second, adolescents are less able to control their impulses than adults; and finally, adolescents are less capable of regulating their emotional responses than adults. Notwithstanding the vigorous use of these scientific findings in the juvenile justice cases, the Court did not address these characteristics of minors in its next adolescent law case, Brown v. Entertainment Merchants Association, where it overturned a statute prohibiting the sale of violent video games to minors. Further, no other courts have invoked these findings to address other aspects ofthe law relating to minors.

This Article reviews the scientific evidence used by the Supreme Court and its implications for other aspects of adolescent law. It explains the nature of the scientific evidence related to minors’ brains, how the Court used such evidence in the juvenile justice and video game cases, and reconciles the two approaches. Using the Court’s treatment as a barometer, this Article then proposes principles and methods for correctly incorporating adolescent brain science into legal policy making, concluding with an example from the contract law protections for minors. Castingthe teachings of science aside is an enormous disservice to the real people who must operate under legal schema, particularly in the case of the young and impressionable who will carry the burden of gaps in the legal system for the rest of their lives. The proper balance is one where good science guides legal policy, but does not dictate individual results.
