In the field of ?neurolaw?, reformists claim that recent scientific discoveries from the mind sciences have serious ramifications for how legal responsibility should be adjudicated, but conservatives deny that this is so. In contrast, I criticise both of these polar opposite positions by arguing that although scientific findings can have often-weighty normative significance, they lack the normative authority with which reformists often imbue them. After explaining why conservatives and reformists are both wrong, I then offer my own moderate suggestions about what views we have reason to endorse. My moderate position reflects the familiar capacitarian idea which underlies much lay, legal, and philosophical thinking about responsibility ? namely, that responsibility tracks mental capacity

Philosophical compatibilism reconciles moral responsibility with determinism, and some neurolaw scholars think that it can also reconcile legal views about responsibility with scientific findings about the neurophysiological basis of human action. Although I too am a compatibilist, this paper argues that philosophical compatibilism cannot be transplanted “as-is” from philosophy into law. Rather, before compatibilism can be re-deployed, it must first be modified to take account of differences between legal and moral responsibility, and between a scientific and a deterministic world view, and to address a range of conceptual, normative, empirical and doctrinal problems that orbit its capacitarian core

The way in which we characterize the structural and functional differences between psychopath and normal brains – either as biological disorders or as mere biological differences – can influence our judgments about psychopaths’ responsibility for criminal misconduct. However, Marga Reimer (Neuroethics 1(2):14, 2008) points out that whether our characterization of these differences should be allowed to affect our judgments in this manner “is a difficult and important question that really needs to be addressed before policies regarding responsibility... can be implemented with any confidence”. This paper is an attempt to address Reimer’s difficult and important question; I argue that irrespective of which of these two characterizations is chosen, our judgments about psychopaths’ responsibility should not be affected, because responsibility hinges not on whether a particular difference is (referred to as) a disorder or not, but on how that difference affects the mental capacities required for moral agency.
