Three Systemic Problems With the Privacy Notice Ecosystem
Privacy notices have become ubiquitous across digital platforms, yet they consistently fail to enable informed user choice about data collection and sharing practices. Despite decades of research and regulatory interventions, users continue to ignore or misunderstand privacy notices. We identify three systemic problems that explain this persistent failure. First, the privacy notice ecosystem suffers from terminological chaos, where identical func…
Who do you think you are? An experimental comparison of online and offline identities using NLP techniques
Researchers have been debating whether our online identities are different from our offline identities since technology enabled us to operate in the digital space. This paper advances the online-offline debate by utilizing Natural Language Processing (NLP) techniques to compare identity-related statements across online and offline contexts. Participants (N = 120) completed twenty “I am...” statements in two conditions: one reflecting online ident…
Good job reporting this!”
The proliferation of conspiracy theories online has tangible offline consequences, both on an individual and collective level. Conspiracy narratives have been associated with reduced belief in democracy, the rise of populist parties, and can act as a radicalization multiplier in such contexts. These narratives capitalize on pre‐existing beliefs and grievances and add urgency to act through a narrative of imminent danger. Previous research has pro…
Rage Against the Machine
The mainstreaming of conspiracy narratives has been associated with a rise in violent offline harms, from harassment, vandalism of communications infrastructure, assault, and in its most extreme form, terrorist attacks. Group-level emotions of anger, contempt, and disgust have been proposed as a pathway to legitimizing violence. Here, we examine expressions of anger, contempt, and disgust as well as violence, threat, hate, planning, grievance, an…
To Like or Not to Like? An Experimental Study on Relational Closeness, Social Grooming, Reciprocity, and Emotions in Social Media Liking
We conducted a randomized-controlled experiment with 201 participants to investigate the effects of relationship closeness, emotions, and the receipt of Likes on reciprocal Liking behaviors. We found that individuals engaged in interchange-oriented social grooming by giving Likes to close friends regardless of whether they had received Likes from them before. However, when relationship closeness was low, participants mirrored their acquaintances’…
Digital traces of offline mobilization
Since 2009, there has been an increase in global protests and related online activity. Yet, it is unclear how and why online activity is related to the mobilization of offline collective action. One proposition is that online polarization (or a relative change in intensity of posting mobilizing content around a salient grievance) can mobilize people offline. The identity-norm nexus and normative alignment models of collective action further argue…
Battle for Britain
In the aftermath of the 2016 referendum on European Union (EU) membership, Britain was divided into identity groups (or tribes) of Leavers and Remainers. In this study, we investigate how Brexit tribalism—in the form of outgroup derogation—has unfolded over time on Twitter. We analyze data from 32 months of discussions ( n = 9,027,822), using identity‐based keywords as proxies for tribalism. First, we characterize the nature of the discussion by …
Emotional responses to likes and comments regulate posting frequency and content change behaviour on social media
Imagined Audiences, Emotions, and Feedback Expectations in Social Media Photo Sharing
The present research explores the effects of imagined audiences, emotions, and feedback expectations on social media photo sharing. We focus on the audience-oriented approach to sharing and on how discrepancies between expected and received feedback might shape photo sharing behaviors. Twenty-four participants were interviewed using scenario-based semi-structured interview method. The participants were asked to develop an imagined story about two…
Changing emotional engagement with running through communal self-tracking
Emerging research explores the role of self-tracking in supporting healthy behaviour. Self-tracking comprises a number of interrelated practices; some individual some communal. In this article, we focus on practices that enable interaction between self-trackers through data sharing and communication around personal data. For public health, communal self-tracking has been explored for the additional benefits it provides in addition to self-knowled…
