Vigorous debate over the moral propriety of cognitive enhancement exists, but the views of the public have been largely absent from the discussion. To address this gap in our knowledge, four experiments were carried out with contrastive vignettes in order to obtain quantitative data on public attitudes towards cognitive enhancement. The data collected suggest that the public is sensitive to and capable of understanding the four cardinal concerns identified by neuroethicists, and tend to cautiously accept cognitive enhancement even as they (...) recognize its potential perils. The public is biopolitically moderate, endorses both meritocratic principles and the intrinsic value of hard work, and appears to be sensitive to the salient moral issues raised in the debate. Taken together, these data suggest that public attitudes toward enhancement are sufficiently sophisticated to merit inclusion in policy deliberations, especially if we seek to align public sentiment and policy.

Transcranial direct current stimulation (tDCS), a simple means of brain stimulation, possesses a trifecta of appealing features: it is relatively safe, relatively inexpensive and relatively effective. It is also relatively easy to obtain a device and the do-it-yourself (DIY) community has become galvanised by reports that tDCS can be used as an all-purpose cognitive enhancer. We provide practical recommendations designed to guide balanced discourse, propagate norms of safe use and stimulate dialogue between the DIY community and regulatory authorities. We call (...) on all stakeholders—regulators, scientists and the DIY community—to share in crafting policy proposals that ensure public safety while supporting DIY innovation. (shrink)

The ambiguity regarding whether a given intervention is perceived as enhancement or as therapy might contribute to the angst that the public expresses with respect to endorsement of enhancement. We set out to develop empirical data that explored this. We used Amazon Mechanical Turk to recruit participants from Canada and the United States. Each individual was randomly assigned to read one vignette describing the use of a pill to enhance one of 12 cognitive, affective or social domains. The vignettes described (...) a situation in which an individual was using a pill to enhance the relevant domain under one of two possible enhancement conditions, one perceived as enhancing above the norm, what most people recognize as a clear case of enhancement, whereas the other perceived as enhancing towards the norm, with the individual using the enhancement having a modest, but subclinical deficit. Participants were asked how comfortable they were with the individual using the enhancement and about the impact the enhancement might have had in the individuals’ success in life. We found that irrespective of the domain to be enhanced, participants felt significantly more comfortable with ETN than with EAN, and they regarded the enhancement intervention as contributing to greater success in life with ETN rather than EAN. These data demonstrate that the therapy enhancement distinction is morally salient to the public, and that this distinction contributes to the angst that people feel when considering the propriety of CAS enhancement.

The debate over the propriety of cognitive enhancement evokes both enthusiasm and worry. To gain further insight into the reasons that people may have for endorsing or eschewing pharmacological enhancement, we used empirical tools to explore public attitudes towards PE of twelve cognitive, affective, and social domains. Participants from Canada and the United States were recruited using Mechanical Turk and were randomly assigned to read one vignette that described an individual who uses a pill to enhance a single domain. After (...) reading the vignette, participants were asked how comfortable they were with the individual using the enhancement. People were significantly more comfortable when they read about enhancement of certain CAS domains than others. We found a modest negative correlation between comfort level and the degree to which the PE was perceived as changing core features of the person. We also found a modest correlation between comfort level and the degree to which the PE was perceived as improving success in life. Finally, using a sequential mixed method technique, we found that participants who felt uncomfortable about PE use overwhelmingly focused on a lack of need and, to a lesser degree, expressed concerns about safety; those who felt comfortable about PE use most frequently mentioned the safety of the pill and its ability to provide a positive outcome. The data provide novel insights into public enthusiasms and concerns over the use of PE. (shrink)

The neural basis of human memory is incredibly complex. We argue that the diversity of neural systems underlying various forms of memory suggests that any discussion of enhancing ‘memory’ per se is too broad, thus obfuscating the biopolitical debate about human enhancement. Memory can be differentiated into at least four major systems with largely dissociable neural substrates. We outline each system, and discuss both the practical and the ethical implications of these diverse neural substrates. In practice, distinct neural bases imply (...) the possibility, and likely the necessity, of specific approaches for the safe and effective enhancement of various memory systems. In the debate over the ethical and social implications of enhancement technologies, this fine-grained perspective clarifies—and may partially mitigate—certain common concerns in enhancement debates, including issues related to safety, fairness, coercion, and authenticity. While many researchers certainly appreciate the neurobiological complexity of memory, the political debate tends to revolve around a monolithic one-size-fits-all conception. The overall project—exploring how human enhancement technologies affect society – stands to benefit from a deeper appreciation of memory’s neurobiological diversity. (shrink)

To gain insight into the reasons that the public may have for endorsing or eschewing pharmacological moral enhancement for themselves or for others, we used empirical tools to explore public attitudes towards these issues. Participants from the United States were recruited via Amazon’s Mechanical Turk and were randomly assigned to read one of several contrastive vignettes in which a 13-year-old child is described as bullying another student in school and then is offered an empathy-enhancing program. The empathy-enhancing program is described (...) as either involving taking a pill or playing a video game on a daily basis for four weeks. In addition, participants were asked to imagine either their own child bullying another student at school, or their own child being bullied by another student. This resulted in a 2 × 2 between-subjects design. In an escalating series of morally challenging questions, we asked participants to rate their overall support for the program; whether they would support requiring participation; whether they would support requiring participation of children who are at higher risk to become bullies in the future; whether they would support requiring participation of all children or even the entire population; and whether they would be willing to participate in the program themselves. We found that people were significantly more troubled by pharmacological as opposed to non-pharmacological moral enhancement interventions. The results indicate that members of the public for the greater part oppose pharmacological moral bioenhancement, yet are open to non-biomedical means to attain moral enhancement. [248 words].

Strategies for improving individual decision making have attracted attention from a range of disciplines. Surprisingly, neuroscience has been largely absent from this conversation, despite the fact that it has recently begun illuminating the neural bases of how and why we make decisions, and is poised for further such advances. Here we address empirical and normative questions about “nudging” through the lens of neuroscience. We suggest that the neuroscience of decision making can provide a framework for understanding how nudges work, and (...) how they can be improved. Towards this end, we first examine how nudges can be incorporated into a leading model of decision making supported by neurobiological data, and use the model to make predictions about the relative effectiveness of different classes of nudges. We then use the model to demonstrate how nudges can both infringe upon and promote autonomy. Finally, we explore the normative implications of the converging consensus from neuroscience and related fields that many everyday decisions are susceptible to covert external influences. (shrink)

Given the ubiquity and centrality of social and relational influences to the human experience, our conception of self-governance must adequately account for these external influences. The inclusion of socio-historical, externalist considerations into more traditional internalist accounts of autonomy has been an important feature of the debate over personal autonomy in recent years. But the relevant socio-temporal dynamics of autonomy are not only historical in nature. There are also important, and under-examined, future-oriented questions about how we retain autonomy while incorporating new (...) values into the existing set that guides our interaction with the world. In this paper, we examine these questions from two complementary perspectives: philosophy and neuroscience. After contextualizing the philosophical debate, we show the importance to theories of autonomous agency of the capacity to appropriately adapt our values and beliefs, in light of relevant experiences and evidence, to changing circumstances. We present a plausible philosophical account of this process, which we claim is generally applicable to theories about the nature of autonomy, both internalist and externalist alike. We then evaluate this account by providing a model for how the incorporation of values might occur in the brain; one that is inspired by recent theoretical and empirical advances in our understanding of the neural processes by which our beliefs are updated by new information. Finally, we synthesize these two perspectives and discuss how the neurobiology might inform the philosophical discussion. (shrink)

Neuroscience has substantially advanced the understanding of how changes in brain biochemistry contribute to mechanisms of tolerance and physical dependence via exposure to addictive drugs. Many scientists and mental health advocates scaffold this emerging knowledge by adding the imprimatur of disease, arguing that conceptualizing addiction as a brain disease will reduce stigma amongst the folk. Promoting a brain disease concept is grounded in beneficent and utilitarian thinking: the language makes room for individuals living with addiction to receive the same level (...) of compassion and access to healthcare services as individuals living with other medical diseases, and promotes enlightened social and legal policies. However such claims may yield unintended consequences by fostering discrimination commonly associated with pathology. Specifically, the language of neuroscience used to describe addiction may reduce attitudes such as blame and responsibility while inadvertently identifying addicted persons as neurobiological others. In this paper, we examine the merits and limitations of adopting the language of neuroscience to describe addiction. We argue that the reframing of addiction in the language of neuroscience provides benefits such as the creation of empowered biosocial communities, but also creates a new set of risks, as descriptive neuroscience concepts are inseparable from historical attitudes and intuitions towards addiction and addicted persons. In particular, placing emphasis on the diseased brain may foster unintended harm by paradoxically increasing social distance towards the vulnerable group the term is intended to benefit. (shrink)

In this commentary on an article by Jennifer Blumenthal-Barby (AJOB 16:5-15, 2016), we discuss how external influences on decisions affect personal autonomy. Specifically, we introduce the idea of “pre-authorization” as an evaluative stance by which an individual gives a certain agent preferential access to influencing her decision-making processes. Influences arising from pre-authorized agents may then be seen as promoting, rather than infringing upon, autonomy. While the idea that an external influence can be autonomy-promoting may be inconsistent with individualistic conceptions of (...) autonomy, it aligns well with more relational conceptions that recognize the social milieu in which decisions are made. We suggest that pre-authorization provides a framework for thinking about how relational accounts of autonomy might work mechanistically. (shrink)

Advances in psychology and neuroscience have elucidated the social aspects of human agency, leading to a broad shift in our thinking about fundamental concepts such as autonomy and responsibility. Here, we address a critical aspect of this inquiry by investigating how people consider the socio-relational nature of their own agency, particularly the influence of others on their perceived control over their decisions and actions. Specifically, in a series of studies using contrastive vignettes, we examine public attitudes about when external influences (...) on everyday decisions are perceived as " undue " – that is, as undermining the control conditions for these decisions to be considered autonomous – vs. when they are perceived as appropriate and even supportive of autonomous decision-making. We found that the influence of preauthorized agents – individuals and institutions with whom we share a worldview – was judged to be less undue than non-preauthorized agents, even after controlling for the familiarity of the agent. These effects persisted irrespective of the extent to which respondents identified as communitarian or individualistic, and were consistent across two distinct scenarios. We also found that external influences that were rational were perceived as less undue than those that were arational. Our study opens new avenues of inquiry into the " folk conception " of autonomy, and we discuss the implications of our findings for the ethics of public policies designed to influence decisions and for information sharing in social networks.
