Nudging is the idea that people’s decisions should be influenced in predictable, non-coercive ways by making changes to the way that options are presented to them. Central to the debate about nudging is the question of whether it is morally permissible to intentionally nudge others. Libertarian paternalists maintain that this can be the case. In this paper, I present the libertarian paternalistic criteria for the moral permissibility of intentional nudges. Having done this, I motivate two objections. The first one targets (...) the moral permissibility of nudging in general. The second one targets the moral permissibility of only a subset of nudges. After evaluating both of these objections, I conclude that although they are unsuccessful, the evaluation of The Manipulation Objection shows that the libertarian paternalistic criteria for the moral permissibility of intentional nudges fails. I end by suggesting a possible revision to the criteria that avoids the problem, considering its limitations, and providing examples of its applications. (shrink)

Advances in cognitive and behavioral science show that the way options are presented—commonly referred to as “choice architecture”—strongly influences our decisions: we tend to react to a particular option differently depending on how it is presented. Studies suggest that we often make irrational choices due to the interplay between choice architecture and systematic errors in our reasoning—cognitive biases. Based on this data, Richard Thaler and Cass Sunstein came up with the idea of a "nudge," which they define as a small (...) change in the choice architecture that steers people towards certain choices without limiting their options. Central to the debate on nudging is the question of when, or under what circumstances, it is ethical to nudge someone. Proponents of nudging argue that for ethical nudging, the nudge must be (1) easy to resist and (2) aimed towards the welfare of those nudged (nudgees). In this paper, I argue that this criterion excludes nudges that are both intuitively permissible and broadly accepted. I propose an alternative set of sufficient conditions for ethical nudging that expands the domain for the ethical application of nudges. My “no harm” criterion states that for a nudge to be ethical, the nudge must (1) be easy to resist, and (2) produce no significant harm for the nudgee. I identify three types of such nudges: Choice Architect nudges, Third Party nudges, and “Meh” nudges, and offer examples for each. (shrink)
