There is nothing in science that could ever say whether choice is voluntary. It could only provide physical explanations for the way choice is constituted. Even if why we choose were said to be socially embedded, or latent, all that could be done, through therapy, is to give a person a heightened perspicuity for this as a phenomenon. It would be the same as giving a student a sense of ethics. To do anything more in this domain is to spread confusion.
