In this paper, I consider whether social robots can nudge us in standard ways, i.e., by influencing choice/behavior in predictable ways, and the ethical issues attached to that. I then argue that social robots can also nudge us in non-standard ways, by influencing in predictable ways cognitive and affective states as opposed to simple choice/behavior, and consider the ethical issues attached to that. Before tackling the issues specific to nudging and its ethics in connection to social robots, I introduce nudging and its ethics more in general.
