Neurotechnologies have the potential to disrupt one’s identity and personality. For this reason, ethical questions about neurotechnologies are widely seen as tied to the value of authenticity. In this comment paper, we propose to expand the theoretical framework of authentic decision-making. We must take into account the various ways in which personal authenticity is socially embedded and intimately related to other people. Shared action and narrative are inescapable; consequently, authenticity is shaped through a negotiation among individuals who rely on one another. We provide several cases to illustrate how the others contribute to the process of self-re-creation.
