Research into cognitive enhancement is highly controversial, and arguments for and against it have failed to identify the logical fallacy underlying this debate: the fallacy of composition. The fallacy of composition is a lesser-known fallacy of ambiguity, but it has been explored and applied extensively to other fields, including economics. The fallacy of composition, which occurs when the characteristics of the parts of the whole are incorrectly extended to apply to the whole itself, and the conclusion is false, should be (...) addressed in the debate on cognitive enhancement and within education. Within cognitive enhancement, the premise that individual distinct cognitive processes can be enhanced by cognitive enhancers leads to the conclusion that they must enhance cognition overall, and this idea is pervasive in the literature. If the goal of cognitive enhancement is to enhance cognition or learning, and not merely individual cognitive processes, then this is a clear example of the fallacy of composition. The ambiguity of “cognitive,” “cognition,” and “enhancement” only perpetuates this fallacy and creates more confusion surrounding the purposes and goals of enhancement. Identifying this fallacy does not threaten the existing body of research; however, it provides a novel framework to explore new avenues for research, education, and enhancement, particularly through education reform initiatives. Education enhances and facilitates learning, and improvements to education could be considered cognitive enhancements. Furthermore, the same fallacy is ubiquitous in education; educators commit it by “teaching to the test” and prioritizing memorization over generalizable skills such as critical thinking and problem solving. We will explore these new avenues for research and highlight principles of learning success from other disciplines to create a clearer understanding of the means and ends of cognitive enhancement. Recognizing the pervasiveness of composition fallacy in cognitive enhancement and education will lead to greater clarity of normative positions and insights into student learning that steer away from fallacious reasoning.

There is mounting evidence that non-invasive brain stimulation devices - transcranial direct current stimulation and transcranial magnetic stimulation could be used for cognitive enhancement. However, the regulatory environment surrounding such uses of stimulation devices is less clear than for stimulant drugs—a fact that has already been commercially exploited by several companies. In this paper, the mechanism of action, uses and adverse effects of non-invasive neurostimulation devices are reviewed, along with social and ethical challenges pertaining to their use as cognitive enhancements. (...) Two regulatory approaches that could be used to facilitate responsible use of these devices as products and services are outlined. Apart from establishing the urgently needed comprehensive regulatory framework, they might provide a starting point for establishing long term physiological and social effects of enhancement uses of tDCS and TMS.
