Can Artificial Intelligence be more effective than human instruction for the moral enhancement of people? The author argues that it only would be if the use of this technology were aimed at increasing the individual's capacity to reflectively decide for themselves, rather than at directly influencing behaviour. To support this, it is shown how a disregard for personal autonomy, in particular, invalidates the main proposals for applying new technologies, both biomedical and AI-based, to moral enhancement. As an alternative to these (...) proposals, this article proposes a virtual assistant that, through dialogue, neutrality and virtual reality technologies, can teach users to make better moral decisions on their own. The author concludes that, as long as certain precautions are taken in its design, such an assistant could do this better than a human instructor adopting the same educational methodology. (shrink)

Many of our daily activities are now made more convenient and efficient by virtual assistants, and the day when they can be designed to instruct us in certain skills, such as those needed to make moral judgements, is not far off. In this paper we ask to what extent it would be ethically acceptable for these so-called virtual assistants for moral enhancement to use subtle strategies, known as “nudges”, to influence our decisions. To achieve our goal, we will first characterise (...) nudges in their standard use and discuss the debate they have generated around their possible manipulative character, establishing three conditions of manipulation. Secondly, we ask whether nudges can occur in moral virtual assistants that are not manipulative. After critically analysing some proposed virtual assistants, we argue in favour of one of them, given that by pursuing an open and neutral moral enhancement, it promotes and respects the autonomy of the person as much as possible. Thirdly, we analyse how nudges could enhance the functioning of such an assistant, and evaluate them in terms of their degree of threat to the subject’s autonomy and their level of transparency. Finally, we consider the possibility of using motivational nudges, which not only help us in the formation of moral judgements but also in our moral behaviour. (shrink)
