RT Journal Article SR Electronic T1 Neuroenhancers, addiction and research ethics JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 605 OP 608 DO 10.1136/medethics-2012-100616 VO 38 IS 10 A1 David Martin Shaw YR 2012 UL http://jme.bmj.com/content/38/10/605.abstract AB In their recent paper in this journal, Heinz and colleagues accuse proponents of cognitive enhancement of making two unjustified assumptions. The first of these is the assumption that neuroenhancing drugs will be safe; the second is that research into cognitive enhancement does not pose particular ethical problems. Heinz and colleagues argue that both these assumptions are false. Here, I argue that these assumptions are in fact correct, and that Heinz and colleagues themselves make several assumptions that undermine their argument. Neuroenhancement does raise several ethical concerns, but safety and research in this area pose no unique difficulties.
