The prospects of enhancing cognitive or motor functions using neuroscience in otherwise healthy individuals has attracted considerable attention and interest in neuroethics (Farah et al., Nature Reviews Neuroscience 5:421–425, 2004; Glannon Journal of Medical Ethics 32:74–78, 2006). The use of stimulants is one of the areas which has propelled the discussion on the potential for neuroscience to yield cognition-enhancing products. However, we have found in our review of the literature that the paradigms used to discuss the non-medical use of stimulant (...) drugs prescribed for attention deficit/hyperactivity disorder (ADHD) vary considerably. In this brief communication, we identify three common paradigms—prescription drug abuse, cognitive enhancement, and lifestyle use of pharmaceuticals—and briefly highlight how divergences between paradigms create important “ethics blind spots”.

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.

Medizinethische Untersuchungen zum Thema Neuroenhancement (NE) wenden sich oft der Frage zu, inwiefern der Einzelne wie auch die Allgemeinheit durch NE zu Schaden kommen können. Gerechtigkeitsprobleme, ein befürchteter Wandel des Menschenbildes oder die Gefahr einer unerwünschten, schleichenden Veränderung der Gesellschaft werden problematisiert. Bezüglich individueller Risiken bleibt es aufgrund des vermeintlichen Zugewinns an Selbstbestimmung und Eigenverantwortung gerne beim Verweis auf die subjektive Kosten-Nutzen-Abwägung. Innerhalb der NE-Debatte gibt es bisher kaum Arbeiten, die die Aspekte der Motivation für die Nutzung von NE aus (...) tiefenpsychologischer Perspektive beleuchten. Das Ziel der vorliegenden Arbeit ist es, diese Aspekte zu analysieren. Die Arbeit soll einen Beitrag zu einem neuen Blickwinkel auf Selbstbestimmung und subjektive Einschätzung der Vor- und Nachteile von NE leisten. Es werden psychologische Aspekte thematisiert, welche die im Kontext von NE übliche Annahme, dass Konsumenten zur Selbstverantwortung fähig seien, problematisch erscheinen lassen, da sie die Wahrnehmung dieser Verantwortung erschweren oder gar unmöglich machen können. In diesem Zusammenhang wollen wir versuchen, für die psychologischen Gefahren und Folgen von NE zu sensibilisieren. Es wird beispielsweise darüber diskutiert, inwiefern der Gebrauch von NE-Technologien eine Persönlichkeit nachhaltig prägen und gerade deshalb das Erleben von Selbstwirksamkeit beeinträchtigen kann. Dies stellt die für die liberale Position zentrale Prämisse, wonach Individuen sich frei und vernünftig entscheiden können, infrage. (shrink)

Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a “necessary” prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of “drug instrumentalization.” Psychoactive drugs are consumed for their effects on mental states. Humans are able to learn (...) that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific “instrumentalization goals” and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future. (shrink)

Many drugs have therapeutic off-label uses for which they were not originally designed. Some drugs designed to treat neuropsychiatric and other disorders may enhance certain normal cognitive and affective functions. Because the long-term effects of cognitive and affective enhancement are not known and may be harmful, a precautionary principle limiting its use seems warranted. As an expression of autonomy, though, competent individuals should be permitted to take cognition- and mood-enhancing agents. But they need to be aware of the risks in (...) chronic use of these agents and to take responsibility for their effects. A reasonable middle ground between these positions is to warn those who choose to enhance that doing so entails risks. (shrink)

We investigated the acceptability and frequency of the use of cognitive enhancement (CE) drugs and three different types of academic misconduct (plagiarism, cheating in exams, and falsifying/fabricating data). Data from a web-based survey among German university students were used. Moral acceptability was relatively low for CE drug use and moderate for academic misconduct, while the correlation of their respective acceptability was moderately weak. Prevalence of CE drug use was lower than for academic misconduct and (very) lightly correlated with the prevalence (...) of plagiarism and fabrication/falsification. Acceptability of the investigated behaviors was associated with higher prevalence rates of each behavior. (shrink)

Research into cognitive biases that impair human judgment has mostly been applied to the area of economic decision-making. Ethical decision-making has been comparatively neglected. Since ethical decisions often involve very high individual as well as collective stakes, analyzing how cognitive biases affect them can be expected to yield important results. In this theoretical article, we consider the ethical debate about cognitive enhancement and suggest a number of cognitive biases that are likely to affect moral intuitions and judgments about CE: status (...) quo bias, loss aversion, risk aversion, omission bias, scope insensitivity, nature bias, and optimistic bias. We find that there are more well-documented biases that are likely to cause irrational aversion to CE than biases in the opposite direction. This suggests that common attitudes about CE are predominantly negatively biased. Within this new perspective, we hope that subsequent research will be able to elaborate this hypothesis and develop effective de-biasing techniques that can help increase the rationality of the public CE debate and thus improve our ethical decision-making.

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)
