 Neuroethical analysis here is essential. Should neural data be admissible for determining sentences or parole decisions? Would that be equivalent to punishing someone for crimes they have not committed? Or is it just a neutral extension of current uses of actuarial information, such as age, gender, and income level? At an extreme, one could imagine using predictive information to detain people who have not yet committed a crime, arresting them before they do. This dystopian scenario, portrayed in the film Minority Report (Speilberg, 2002), also illustrates how our abilities to predict can raise difficult ethical and policy questions when they collide with intuitions about and the value of free will and autonomy. More generally, work in neuroethics could be of significant practical use for the law, and indeed is often called by another moniker, “neurolaw” (see section 2.7).
