Cognitive enhancement aims at optimizing a specific class of information-processing functions: cognitive functions, physically realized by the human brain. This article deals with ethical issues in cognitive enhancement. It discusses some standard conceptual issues related to the notion of “cognitive enhancement” and then continues from a purely descriptive point of view by briefly reviewing some empirical aspects and sketching the current situation. Several enhancement strategies are being tested and used. Then the chapter offers some reflections on the treatment or enhancement (...) distinction. It turns to normative issues by describing standard topics in current debates, then highlighting three examples of relevant novel questions under an ethical perspective. It is of central importance to be able to draw on long-term studies yielding data on the benefits, risks, and side-effects involved in the use of such substances over months and years. It concludes by making some general proposals for policy makers. (shrink)

In an essay on performance-enhancing drugs, author Chuck Klosterman (2007) argues that the category of enhancers extends from hallucinogens used to inspire music to steroids used to strengthen athletes—and he criticizes those who would excuse one means of enhancement while railing against the other as a form of cheating: After the summer of 1964, the Beatles started taking serious drugs, and those drugs altered their musical performance. Though it may not have been their overt intent, the Beatles took performance-enhancing drugs. (...) And . . . absolutely no one holds it against them. No one views “Rubber Soul” and “Revolver” as “less authentic” albums, despite the fact that they would not (and probably could .. (shrink)

There is mounting evidence that methylphenidate (MPH; Ritalin) is being used by healthy college students to improve concentration, alertness, and academic performance. One of the key concerns associated with such use of pharmaceuticals is the degree of freedom individuals have to engage in or abstain from cognitive enhancement (CE). From a pragmatic perspective, careful examination of the ethics of acts and contexts in which they arise includes considering coercion and social pressures to enhance cognition. We were interested in understanding how (...) university students, parents of university students, and healthcare providers viewed autonomy and coercion in CE using MPH. We found that perspectives converged on the belief that CE is a matter of personal and individual choice. Perspectives also converged on the existence of tremendous social pressures to perform and succeed. Parents emphasized personal responsibility and accountability for CE choices, and expressed feelings of worry, sadness and fear about CE. Students emphasized the importance of personal integrity in CE, expressed tolerance for personal choices of others, and highlighted the challenge that CE poses to maintaining one’s personal integrity. Healthcare providers emphasized the health consequences of CE. These results illustrate: (1) the importance of understanding how context is viewed in relation to perspectives on autonomous choice; (2) the limitations of individualistic libertarian approaches that do not consider social context; and (3) the ethical implications of public health interventions in a value-laden debate where perspectives diverge.

The hopes and fears expressed in the debate on human enhancement are not always based on a realistic assessment of the expected possibilities. Discussions about extreme scenarios may at times obscure the ethical and policy issues that are relevant today. This paper aims to contribute to an adequate and ethically sound societal response to actual current developments. After a brief outline of the ethical debate concerning neuro-enhancement, it describes the current state of the art in psychopharmacological science and current uses (...) of psychopharmacological enhancement, as well as the prospects for the near future. It then identifies ethical issues regarding psychopharmacological enhancements that require attention from policymakers, both on the professional and on the governmental level. These concern enhancement research, the gradual expansion of medical categories, off-label prescription and responsibility of doctors, and accessibility of enhancers on the Internet. It is concluded that further discussion on the advantages and drawbacks of enhancers on a collective social level is still needed. (shrink)

Using medical advances to enhance human athletic, aesthetic, and cognitive performance, rather than to treat disease, has been controversial. Little is known about physicians? experiences, views, and attitudes in this regard. We surveyed a national sample of physicians to determine how often they prescribe enhancements, their views on using medicine for enhancement, and whether they would be willing to prescribe a series of potential interventions that might be considered enhancements. We find that many physicians occasionally prescribe enhancements, but doctors hold (...) nuanced and ambiguous views of these issues. Most express concerns about the potential effects of enhancements on social equity, yet many also believe specific enhancements that are safe and effective should be available but not covered by insurance. These apparently contradictory views might reflect inherent tensions between the values of equity and liberty, which could make crafting coherent social policies on medical enhancements challenging.

During the past few years considerable debate has arisen within academic journals with respect to the use of smart drugs or cognitive enhancement pharmaceuticals. The following paper seeks to examine the foundations of this cognitive enhancement debate using the example of methylphenidate use among college students. The argument taken is that much of the enhancement debate rests upon inflated assumptions about the ability of such drugs to enhance and over-estimations of either the size of the current market for such drugs (...) or the rise in popularity as drugs for enhancing cognitive abilities. This article provides an overview of the empirical evidence that methylphenidate has the ability to significantly improve cognitive abilities in healthy individuals, and examines whether the presumed uptake of the drug is either as socially significant as implied or growing to the extent that it requires urgent regulatory attention. In addition, it reviews the evidence of side-effects for the use of methylphenidate which may be an influential factor in whether an individual decides to use such drugs. The primary conclusions are that neither drug efficacy, nor the benefit-to-risk balance, nor indicators of current or growing demand provide sufficient evidence that methylphenidate is a suitable example of a cognitive enhancer with mass appeal. In light of these empirically based conclusions, the article discusses why methylphenidate might have become seen as a smart drug or cognitive enhancer. (shrink)

Undergraduates (total N = 185) were asked about performance-affecting drugs. Some drugs supposedly affected athletic performance, others memory, and others attention. Some improved performance for anyone who took them, others for the top 10% of performers, others for the bottom 10%, and finally, yet other drugs worked only on the bottom 10% who also showed physical abnormalities. Participants were asked about the fairness of allowing the drug to be used, about banning it, and about whether predictions of future performance based (...) on testing with or without the drug were better. The study found that participants appreciated the "interaction effect", that they felt it was less unfair to allow the drug if it affected the bottom 10% than if it affected everyone, and they were more eager to have the drug banned if it affected everyone. Participants were least tolerant of drugs that affected athletic performance and most tolerant of those that affected attention. (shrink)

Advances in cognitive neuroscience make cosmetic neurology in some form inevitable and will give rise to extremely difficult ethical issuesConsider the following hypothetical case study. A well heeled executive walks into my cognitive neurology clinic because he is concerned that he is becoming forgetful. It turns out that he is going through a difficult divorce and my clinical impression is that his memory problems stem from the stress he is experiencing. I place him on a selective seratonin reuptake inhibitor, sertraline, (...) and in a few weeks he feels better. Around this time his 13 year old daughter has difficulty at school and is diagnosed by the school psychologist as having attention deficit disorder. I place her on adderall, a stimulant combination drug, which seems to help with her behaviour in school. My patient then comes to me because he is experiencing the “tip of the tongue” phenomena more frequently. He is concerned that his word finding difficulty interferes with his ability to function in high level meetings. I suggest we try a cholinesterase inhibitor to see if this helps. I am careful to explain that the Food and Drug Administration does not approve such a use for this medication. He wants to try it and is pleased with the results.A few months later, this patient visits me with his 16 year old son, a talented middle distance runner. His father thinks if he were just a bit better, among the elite high school runners in the state, he would be far more competitive as an applicant for selective colleges. We discuss various options. Because of a recent report that sildenafil, which is used conventionally for male impotence, may improve oxygen carrying capacity, I prescribe this medication. The son does not object.Encouraged by these pharmacologic successes, my patient …. (shrink)

There is currently little empirical information about attitudes towards cognitive enhancement - the use of pharmaceutical drugs to enhance normal brain functioning. It is claimed this behaviour most commonly occurs in students to aid studying. We undertook a qualitative assessment of attitudes towards cognitive enhancement by conducting 19 semi-structured interviews with Australian university students. Most students considered cognitive enhancement to be unacceptable, in part because they believed it to be unethical but there was a lack of consensus on whether it (...) was similar or different to steroid use in sport. There was support for awareness campaigns and monitoring of cognitive enhancement use of pharmaceutical drugs. An understanding of student attitudes towards cognitive enhancement is important in formulating future policy. (shrink)

One frequently used argument in the discussion on human enhancement is that enhancement is a form of cheating. This argument is well-known in relation to doping in sports, but recently it has also been used with regard to cognitive enhancement in the context of education and exams. This paper analyses the enhancement-is-cheating argument by comparing sports and education, and by evaluating how the argument can be interpreted in both contexts. If cheating is understood as breaking the rules in order to (...) gain an unfair advantage over others, it can be argued that some enhancements are a form of cheating. This problem of cheating is, however, relatively easy to remedy by either changing the rules, or by instituting controls and sanctions. This does not, therefore, constitute a categorical objection to enhancement. A further analysis of the intuitions behind the enhancement-is-cheating argument, however, shows that if sports and education are understood as “practices”, with their own internal goods and standards of excellence, some potential problems of enhancement can be articulated. These concern the internal goods and standards of excellence that are characteristic of specific practices. Seen from this perspective, the important question is how enhancement technologies might be embedded in specific practices—or how they might corrode them. (shrink)

The use of psychopharmaceuticals to enhance human mental functioning such as cognition and mood has raised a debate on questions regarding identity and authenticity. While some hold that psychopharmaceutical substances can help users to ‘become who they really are’ and thus strengthen their identity and authenticity, others believe that the substances will lead to inauthenticity, normalization, and socially-enforced adaptation of behaviour and personality. In light of this debate, we studied how persons who actually have experience with the use of psychopharmaceutical (...) medication would view their ‘self’ or their authentic personal identity in relation to the use of medication. We have interviewed a number of adults diagnosed with ADHD and discussed their experiences with medication use in relation to their conceptions of self and identity. In the first part of this paper we illustrate that the concepts of identity and authenticity play an important and sometimes problematic role in experiences of ADHD adults. This shows that the question about identity and psychopharmacology is not merely an ‘academic’ issue, but one that influences everyday lives of real people. In order to answer the question whether psychopharmaceuticals threaten personal identity and authenticity, more than empirical research is needed. We also need to analyse the concepts of personal identity, authenticity and self: what do we mean when we are using statements as ‘a way of living that is uniquely our own’, ‘our true self’, or ‘who we really are’? In the second part of this paper we discuss two important philosophical views on personal identity, authenticity and self: the self-control view as elaborated by Frankfurt, and the self-expression view as proposed by Schechtman. We compare these with the experiences of our respondents to see which view can help us to understand the diverse and often conflicting experiences that people have with medication for ADHD. This will contribute to a better understanding of whether and in which cases personal identity and authenticity are threatened by psychopharmacology. (shrink)

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.

A person can be true to oneself even while transforming and even creating the person one is. One's self is not something merely waiting to be discovered, after all. To some extent, part of the human endeavor is deciding and trying to become who we want to be.
