  Research on Digital Nudging has become increasingly popular in the
Information Systems (IS) community. This paper presents an overview of the
current progress, a critical reflection and an outlook to further research
regarding Digital Nudging in IS. For this purpose, we conducted a comprehensive
literature review as well as an interview with Markus Weinmann from Rotterdam
School of Management at Erasmus University, one of the first scholars who
introduced Digital Nudging to the IS community, and Alexey Voinov, director of
the Centre on Persuasive Systems for Wise Adaptive Living at University of
Technology Sydney. The findings uncover a gap between what we know about what
constitutes Digital Nudging and how consequent requirements can actually be put
into practice. In this context, the original concept of Nudging bears inherent
challenges, e.g. regarding the focus on the individuals' welfare, which hence
also apply to Digital Nudging. Moreover, we need a better understanding of how
Nudging in digital choice environments differs from that in the offline world.
To further distinguish itself from other disciplines that already tested
various nudges in many different domains, Digital Nudging Research in IS may
benefit from a strong Design Science perspective, going beyond the test of
effectiveness and providing specific design principles for the different types
of digital nudges.
