Abstract

Our ability to locate moral responsibility is often thought to be a necessary condition for conducting morally permissible medical practice, engaging in a just war, and other high-stakes endeavors. Yet, with increasing reliance upon artificially intelligent systems, we may be facing a widening responsibility gap, which, some argue, cannot be bridged by traditional concepts of responsibility. How then, if at all, can we make use of crucial emerging technologies? According to Colin Allen and Wendell Wallach, the advent of so-called ‘artificial moral agents’ (AMAs) is inevitable. Still, this notion may seem to push back the problem, leaving those who have an interest in developing autonomous technology with a dilemma. We may need to scale-back our efforts at deploying AMAs (or at least maintain human oversight); otherwise, we must rapidly and drastically update our moral and legal norms in a way that ensures responsibility for potentially avoidable harms. This paper invokes contemporary accounts of responsibility in order to show how artificially intelligent systems might be held responsible. Although many theorists are concerned enough to develop artificial conceptions of agency or to exploit our present inability to regulate valuable innovations, the proposal here highlights the importance of—and outlines a plausible foundation for—a workable notion of artificial moral responsibility.

15. In this way, those who plead ignorance are attempting to eschew responsibility by dissolving their agency.

Journal of Business Ethics 2015;127:707715.CrossRefGoogle Scholar My account will be consistent with Johnson’s view that the “responsibility gap depends on human choices.” However, while Johnson focuses on the design choices in technology itself, the choices that occupy my attention concern how and where we direct our responsibility practices.

48. Consider also that we punish corporations (e.g. by imposing fines) despite the implausibility of such entities displaying the right sort of response, an anonymous reviewer aptly notes. By contrast, consequential accounts of punishment can be seen as inadequate depictions of moral blame, since they don’t fully explain our attitudes and might not properly distinguish wrongdoers from others. See Wallace, RJ. Responsibility and the Moral Sentiments. Harvard University Press 1994; 5262.Google Scholar I’m grateful to Sven Nyholm for discussion here.

49. Proponents of the ‘process view’ applied to technology can be said to include Johnson, DG, Miller, KW. Un-making artificial moral agents.

55. However, these sorts of sanctioning mechanisms are less likely to succeed where the target AI system has surpassed humans in general intelligence.

56. Such ‘bottom-up’ moral development in AI is discussed in Allen and Wallach 2009 (note 6). Compare also Hellström, T. On the moral responsibility of military robots. Ethics and Information Technology 2013;15:99107CrossRefGoogle Scholar. Again, for some (e.g. Wallace 1994, in note 48), consequential accounts of responsibility will be unsatisfying. While a fuller discussion isn’t possible here, in short, my goal has been to unearth general mechanisms for holding diverse objects responsible, which admittedly will deviate from the robust sorts of responsibility (and justifications) we ascribe to natural moral agents. Again, I’m here indebted to Sven Nyholm.

58. Similarly, Helen Nissenbaum suggests that although accountability is often undermined by computing, we can and should restore it, namely by promoting an ‘explicit standard of care’ and imposing ‘strict liability and producer responsibility.’ Nissenbaum, H. Computing and accountability. Communications of the ACM 1994;37:7280CrossRefGoogle Scholar; Nissenbaum, H. Accountability in a computerized society.

61. John Danaher likewise frames the problem in terms of trade-offs, namely increases in efficiency and perhaps well-being, but at the cost of human participation and comprehension. See Danaher, J.
