methods for the research on digital nudging.
The study conducts an exhaustive literature review and adopts the“who-what-why-how”
4-dimensional framework to specify the concept of digital nudging with a focus on “how”
dimension, namely the theoretical foundation of nudges design, from a social psychology
perspective. Based on this framework, the study also illustrates how manipulating elements of
human-computer interaction leads to nudging by reviewing the extant empirical research. Further,
the study demonstrates the application scenarios of digital nudging by analyzing the applied
concepts research and conceptual orientation research. On July 26th, 2019, the authors retrieved
the relevant literature from the database of Web of Science by setting the topic as “digital nudge”
and “digital nudging”. Besides, another 3 studies citing the pioneering study Weinmann et al.
were also taken into consideration. The further literature review was based on 23 studies in total.
The results show that: 1) the research on digital nudging is in its infancy and the empirical and
non-empirical studies are evenly matched in number; 2) the 21 nudges designed based on social
psychology theories can be embedded in human-computer interfaces and effectively play the role
of digital nudging; 3) there are 9 application scenarios for digital nudges and the application in
practice is illustrated with a flowchart. Due to the limited number of studies retrieved, the study
did not use bibliometrics.
Digital nudging has been proven to be applicable in the typical technology industries such as
intelligent agent, digital goods design, music player, and the fields which are closely related to the
daily life of the general public including sustainable consumption, green transportation, education,
just to name a few. The theoretical foundations of nudges design and the flowchart are able to
provide guidance for the application of nudges in these fields. The originality of this article is
manifold. It systematically sorts out the concept of digital nudging through the “who-what-why-
how” 4-dimensional framework and further analyzes the theoretical foundations for nudges design
from the perspective of social psychology. Moreover, the study illustrates the research on digital
nudging with the analysis of empirical studies and demonstrates the application scenarios of digital
nudges through the analysis of non-empirical studies. Jointly, the status quo of the research would
promote digital nudging in theory and practice.
