We frequently share personal data with companies when using online services. Oftentimes, these data not only include information about ourselves, but also information we hold about others, for example friends and family. In their recent research, Joris Demmers, Andrea N. Weihrauch, and Frauke H. Mattison Thompson from the University of Amsterdam examine whether consumers differ in their willingness to share others’ data depending on their social value orientation. Their findings reveal that selfish people are less likely to share others’ data compared to prosocial people, because they feel less ownership for others’ data than prosocials do. Thus, possibly contrary to your own intuition, you might want to trust your selfish friend more than your prosocial friend when it comes to your online privacy.

Demmers et al. (2021) argue that feelings of ownership are the reason why people are more or less likely to infringe on others’ privacy. Future research should have a closer look at further explanations for why people infringe on others’ privacy by sharing their data online. When is the cost of infringing on someone else’s privacy perceived as justifiable? An even deeper understanding of why these so called interpersonal privacy infringements occur is essential to prevent possible harmful consequences of this behavior. Check out this article by Kamleitner and Mitchell (2019) to find out more about the phenomenon of interpersonal privacy infringements.
