Title:
Privacy Nudges and Self-Censorship on Social Media
Abstract:
Anecdotal evidence and scholarly research have shown that a significant portion of Internet users experience regrets over their social network disclosures. To help individuals avoid regrettable disclosures, we employed lessons from behavioral decision research and soft paternalism to design mechanisms that "nudge" users to consider the content and context of their online disclosures more carefully. We developed three privacy nudges for Facebook, focusing on visual cues about the audience, time delays, and feedback mechanisms. I will talk about how our research on regrettable disclosures on social networks informed our Facebook privacy nudge designs and present results of our field trials. While nudges are designed to encourage self-censorship, many social network users already practice self-censorship regularly. I will also discuss a study in which we explored self-censorship on Facebook by asking participants to report all content that they thought about sharing but decided not to share on Facebook for a week. Our results shed light on the types of content users tend to self-censor as well as the difficulties Facebook users have in precisely targeting content to a desired audience.
