10. Conclusion
We started experimenting with nudges in authentication four years ago. During the course of carrying out our experiments we became aware of the fact that there were no nudge-specific ethical guidelines in place to guide us. We therefore reviewed the literature to derive these. When we started to peruse the literature, we realized that we needed first to delineate the nudge concept properly. Afterwards, we were able to synthesize arguments for, and against, nudging. We then mapped these onto ethical principles obtained from ethical guidelines developed for psychological research. We conclude with a set of preliminary ethical principles formulated to guide nudge Info-S&P researchers.
This paper is not intended to be the final word on the subject; the authors hope that other Info-S&P researchers will help us to work towards extending and refining these principles to arrive at a resource that can benefit Ethical Review Boards and help them to judge proposed Info-S&P nudge-related research.
