 This may still be largely true, but even the privacy of the mind can no longer to be taken for granted. Our neuroscientific achievements have already made significant headway in allowing others to discern some aspects of our mental content through neurotechnologies. Noninvasive methods of brain imaging have revolutionized the study of human cognition and have dramatically altered the kinds of knowledge we can acquire about people and their minds. Niether is the threat to mental privacy as simple as the naive claim that neuroimaging can read our thoughts, nor are the capabilities of imaging so innocuous and blunt that we needn’t worry about that possibility. A focus of neuroethics is to determine the real nature of the threat to mental privacy, and to evaluate its ethical implications, many of which are relevant to legal, medical, and other social issues (Shen, 2013). For example, in a world in which the bastion of the mind may be lowering its drawbridges, do we need extra protections? Doing so effectively will require both a solid understanding of the neuroscientific technologies and the neural bases of thought, as well as a sensitivity to the ethical problems raised by our growing knowledge and ever-more-powerful neurotechnologies. These dual necessities illustrate why neuroethicists must be trained both in neuroscience and in ethics. In what follows I briefly discuss the most relevant neurotechnology and its limitations and then canvas a few ways in which privacy may be infringed by it.
