Neuroscience Fiction as Eidola: Social Reflection and Neuroethical Obligations in Depictions of Neuroscience in Film

Neuroscience and neurotechnology are increasingly being employed to assess and alter cognition, emotions, and behaviors, and the knowledge and implications of neuroscience have the potential to radically affect, if not redefine, notions of what constitutes humanity, the human condition, and the "self." Such capability renders neuroscience a compelling theme that is becoming ubiquitous in literary and cinematic fiction. Such neuro-SciFi (or "NeuroS/F") may be seen as eidola: a created likeness that can either accurately-or superficially, in a limited way-represent that which it depicts. Such eidola assume discursive properties implicitly, as emotionally salient references for responding to cultural events and technological objects reminiscent of fictional portrayal; and explicitly, through characters and plots that consider the influence of neurotechnological advances from various perspectives. We argue that in this way, neuroS/F eidola serve as allegorical discourse on sociopolitical or cultural phenomena, have power to restructure technological constructs, and thereby alter the trajectory of technological development. This fosters neuroethical responsibility for monitoring neuroS/F eidola and the sociocultural context from which and into which-the ideas of eidola are projected. We propose three approaches to this: evaluating reciprocal effects of imaginary depictions on real-world neurotechnological development; tracking changing sociocultural expectations of neuroscience and its uses; and analyzing the actual process of social interpretation of neuroscience to reveal shifts in heuristics, ideas, and attitudes. Neuroethicists are further obliged to engage with other discourse actors about neuroS/F interpretations to ensure that meanings assigned to neuroscientific advances are well communicated and more fully appreciated.
