Neurolaw: Challenges and limits

This chapter canvasses the current relevance of behavioral neuroscience to the law, especially to issues of criminal responsibility and competence. It begins with an explanation of the legal doctrines at stake. I then explore the source of the often-inflated claims for the legal relevance of neuroscience. The next section discusses the scientific status of behavioral neuroscience. Then, it addresses two radical challenges to current conceptions of criminal responsibility that neuroscience allegedly poses: determinism and the death of agency. The question of the specific relevance of neuroscience to criminal law doctrine, practice, and institutions is considered next. This is followed by a discussion of how neuroscience evidence is being used in criminal cases in five different countries, including the United States. The penultimate section points to some areas warranting modest optimism. A brief conclusion suggests that neuroscience is at present of limited legal relevance, and advances in the science might alter that judgment.
