The term ‘privacy paradox’ refers to the apparent inconsistency between privacy concerns and actual behaviour that also often leads to the dominance of privacy-careless over privacy-respecting platforms. One of the most important explanations for this phenomenon is based on the concept of social norm, which refers to the influence that an individual’s social environment can have on their decisions to accept or reject a specific platform. However, the interdependencies between social norm dynamics and platform adoption have received little attention so far. To overcome this limitation, this article presents a system dynamics simulation model that considers the concept of social norm, shaped by users with diverse privacy concerns, during the adoption process of two alternative social media platforms and identifies the types of situations in which the privacy paradox emerges. The results show a bidirectional minority rule, where (1) the least concerned minority can hinder the more concerned majority from discarding a privacy-careless platform but also (2) the most concerned minority can induce the less concerned majority to adopt a privacy-respecting platform. Both (1) and, to a lesser extent, (2) are types of situations that reflect the privacy paradox.
