Autonomous nudges and AI choice architects – where does responsibility lie in computer mediated decision making?

AI and algorithms shape many aspects of our everyday life, from the familiar algorithms structuring our social media feeds, to those subtly transforming more complex fields, such as policymaking and commerce. Stuart Mills argues that as these choice architects become increasingly autonomous and automatic, and produce nudges that are difficult if not impossible to explain, there is a need to reassess the ethical limits underpinning how and who is nudged.
