ABSTRACT

Choice Architectures, the design of interfaces in which choices are presented to users, have a tremendous effect on people’s decisions. Even subtle changes in the choice architecture, such as the selection of default options, can significantly alter the decisions of users, nudging them to specific directions, and even change the way they perceive their possibilities. In this talk, we will discuss several studies that analysed and optimised choice architectures to enhance users’ privacy and security decisions. We will start by reviewing the relation between the economic view of choice architecture and the design of actual user interfaces for making choices in the context of data privacy and security. We will introduce concepts such as population coverage and fairness that quantitatively model the choice architecture, and see how these concepts can be used to empirically analyse systems such as social networks and security warning systems. Finally, we will learn how choice architectures can be optimised to reflect users’ actual preferences, and how we can effectively nudge users towards a more secure behaviour.
