Who should you entrust with your data? – Your selfish or your prosocial friend?

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.

Psychological ownership and prosocial behavior

Research on the consequences of psychological ownership has mostly focused on its effects on the relationship with a specific target of ownership. But could it be that psychological ownership also has carry-over effects on domains unrelated to the specific target of ownership? A new research by Ata Jami (Northwestern University), Maryam Kouchaki (Northwestern University), and Francesca Gino (Harvard University) examines this question. Specifically, the authors propose that psychological ownership increases prosocial behavior behavior because it boosts people’s self-esteem and therefore makes them more willing to help out. They also identify materialism and mine-me sensitivity as moderators of this effect. This research suggests that psychological ownership besides having profound implications on our relationships with possessions can also affect behavior in unrelated domains, such as altruistic behavior.
