In the debate on the ethics of the non-medical use of pharmaceuticals for cognitive performance enhancement in healthy individuals there is a clear division between those who view “cognitive enhancement” as ethically unproblematic and those who see such practices as fraught with ethical problems. Yet another, more subtle issue, relates to the relevance and quality of the contribution of scholarly bioethics to this debate. More specifically, how have various forms of speculation, anticipatory ethics, and methods to predict scientific trends and (...) societal responses augmented or diminished this contribution? In this paper, we use the discussion of the ethics of cognitive enhancement to explore the positive and negative contribution of speculation in bioethics scholarship. First, we review and discuss how speculation has relied on different sets of assumptions regarding the non-medical use of stimulants, namely: terminology and framing; scientific aspects such as efficacy and safety; estimates of prevalence and consequent normalization; and the need for normative reflection and regulatory guidelines. Second, three methodological guideposts are proposed to alleviate some of the pitfalls of speculation: acknowledge assumptions more explicitly and identify the value attributed to assumptions; validate assumptions with interdisciplinary literature; and adopt a broad perspective to promote more comprehensive reflection. We conclude that, through the examination of the controversy about cognitive enhancement, we can employ these methodological guideposts to enhance the value of contributions from bioethics and minimize potential epistemic and practical pitfalls in this case and perhaps in other areas of bioethical debate.

The article explores some of the issues that have arisen in the discourse on pharmaceutical cognitive enhancement (PCE), that is, the use of stimulant drugs such as methylphenidate, amphetamine and modafinil by healthy individuals of various populations with the aim of improving cognitive performance. Specifically, we explore the presumed sizes of existing PCE user populations and the policy actions that have been proposed regarding the trend of PCE. We begin with an introductory examination of the academic stances and philosophical issues (...) involved in defining PCE. We then focus on an examination of the population sizes of presumed current PCE users that have been listed in the academic literature on PCE, on presuppositions, which have been problematized by some authors as based on anecdotal or misinterpreted survey data. We follow this with an empirical examination of a potential PCE user population in a national context (students at the University of Ljubljana in Slovenia). We then proceed to examine the regulatory options proposed in the academic literature to address PCE, finally comparing them with an empirical overview of the policy recommendations on PCE produced in the multinational context of several national ethics advisory bodies (EABs) in Europe. Our main conclusion is that there is still little debate among the national EABs on what type of public policy responses, if any, are needed to address PCE in European countries, and that the issues they do address are similar to those discussed and proposed in the academic articles on PCE.

There exists a significant disparity within society between individuals in terms of intelligence. While intelligence varies naturally throughout society, the extent to which this impacts on the life opportunities it affords to each individual is greatly undervalued. Intelligence appears to have a prominent effect over a broad range of social and economic life outcomes. Many key determinants of well-being correlate highly with the results of IQ tests, and other measures of intelligence, and an IQ of 75 is generally accepted as (...) the most important threshold in modern life. The ability to enhance our cognitive capacities offers an exciting opportunity to correct disabling natural variation and inequality in intelligence. Pharmaceutical cognitive enhancers, such as modafinil and methylphenidate, have been shown to have the capacity to enhance cognition in normal, healthy individuals. Perhaps of most relevance is the presence of an ‘inverted U effect’ for most pharmaceutical cognitive enhancers, whereby the degree of enhancement increases as intelligence levels deviate further below the mean. Although enhancement, including cognitive enhancement, has been much debated recently, we argue that there are egalitarian reasons to enhance individuals with low but normal intelligence. Under egalitarianism, cognitive enhancement has the potential to reduce opportunity inequality and contribute to relative income and welfare equality in the lower, normal intelligence subgroup. Cognitive enhancement use is justifiable under prioritarianism through various means of distribution; selective access to the lower, normal intelligence subgroup, universal access, or paradoxically through access primarily to the average and above average intelligence subgroups. Similarly, an aggregate increase in social well-being is achieved through similar means of distribution under utilitarianism. In addition, the use of cognitive enhancement within the lower, normal intelligence subgroup negates, or at the very least minimises, several common objections to cognitive enhancement. Subsequently, this paper demonstrates that there is a compelling case for cognitive enhancement use in individuals with lower, normal intelligence. (shrink)
