What I Really, Really Want: The Role, Nature, and Value of True Preferences in the Ethics of Nudging

In this article, we discuss the role that 'true preferences' can and should play in discussions on the possibility and desirability of paternalist nudges. Critics have claimed that such preferences do not exist, cannot be known reliably by third parties, and cannot justify whether and how to nudge people. In this article, we argue that these objections undermine the extent to which philosophers and laypeople can make sense of autonomy and authenticity. We aim to identify what kinds of preferences can plausibly be labelled 'true' and how that impacts discussions on the ethics of paternalist nudging. We analyse what 'true preferences' can mean, not for Econs, but for Humans, and argue, more specifically, that some of our existing preferences have special status. In addition, we argue that satisfying them is good for individuals and that nudgers should seek to overcome the epistemic challenges of discovering their content.
