From Public Spheres to Counterpublics: A Data-Driven Investigation of Social Media Engagement and User Well-Being (Master)
In today’s digitally mediated society, social media platforms are arenas where stereotypes, prejudice, and discrimination are both reproduced and reconfigured. Digital features—such as anonymity, publicized privacy, and context collapse—often expose users to discriminatory content in the public sphere. This exposure can heighten feelings of vulnerability, prompting marginalized groups to leave mainstream public spaces in favor of forming counterpublics. Within these niche environments, users find support, challenge dominant narratives, and mobilize social activism. While passive engagement in the public sphere is associated with negative psychological outcomes, active participation in counterpublics tends to foster positive well-being. The spiral of silence theory further elucidates how dissenting voices are muted in hostile environments, and recent models of active versus passive social media use (Verduyn, Gugushvili, & Kross, 2022) underscore the complex interplay between digital engagement and mental health.
This thesis proposes a data-driven investigation into how digital environments influence user well-being through patterns of social media engagement. Building on the extended active-passive model, the study hypothesizes that mainstream public spheres—characterized by exposure to discriminatory content and hostile reactions—encourage passive usage and lower well-being, whereas counterpublics provide a safer space that promotes active engagement and enhances well-being.
Research Questions & Hypotheses:
- RQ1: How does exposure to discriminatory content in the public sphere influence user engagement patterns on social media?
- RQ2: Do users in counterpublics exhibit higher levels of active engagement and report better well-being compared to those in mainstream public spheres?
- H1: Users frequently exposed to discriminatory content in mainstream public spheres will show increased passive engagement behaviors and report lower well-being.
- H2: Users active in counterpublics will demonstrate higher active engagement metrics and report enhanced well-being.
Possible Methodology:
Data Collection:
- Employ web scraping techniques (using APIs and custom scripts) to gather posts, comments, and interaction data from social media platforms such as Twitter and Reddit.
- Categorize data into two groups: content originating from mainstream public spheres versus counterpublic spaces, based on established criteria from research on public spheres, counterpublics, and context collapse.
Data Analysis:
- Content Analysis: Use natural language processing (NLP) methods to detect discriminatory language and measure sentiment in posts.
- Engagement Metrics: Classify user behavior as active (e.g., posting, commenting, sharing) or passive (e.g., lurking, minimal interaction).
- Statistical Testing: Apply regression analysis and other statistical techniques to correlate exposure to discriminatory content, engagement type, and self-reported well-being (integrating survey data where available).
- Validation: Triangulate findings by comparing scraped behavioral data with user self-reports and established theoretical models such as the extended active-passive model (Verduyn, Gugushvili, & Kross, 2022).

The Emotional Divide: Affective Polarization Across different Social Media Platforms (Master)
Description
Affective polarization is defined as a growing emotional division between groups and has emerged as a defining challenge of the digital age. Social media platforms, such as TikTok, Reddit, YouTube, X or Bluesky , facilitate rapid information diffusion and enable users to form and reinforce emotion-driven communities. Due to the platform infrastructures, occuring narratives and according (negative and positive) emotions which are propagated differently across platform ecosystems, a reinforcement of affective issues within a digital social sphere might be noticiable.
This thesis explores a cross channel analysis to understand how affective polarization manifests, evolves, and diffuses across distinct social media environments. Drawing on existing theories of affective polarization, networked communication and platform-mediated discourse, it examines how content characteristics (AI generated and human generated), audiences or algorithmic factors shape the emotional gap between opposing groups. By integrating data from multiple platforms, the qualitative and/or quantitave analysis seeks to uncover how cross-channel dynamics intensify affective divides and discovers potential pathways for mitigation of negative effects.
Requirements
You should be interested in cognitive emotion science and how to support social cohesion in order to connect the phenomenon of affective polarization with the information systems research.

Discrimination in Social Media: A Systematic Literature Review
In today’s digitally mediated society, social media platforms are arenas where stereotypes, prejudice, and discrimination are both reproduced and reconfigured. Digital features—such as anonymity, publicized privacy, and context collapse—often expose users to discriminatory content in the public sphere. This exposure can prompt marginalized groups to transition away from mainstream public spaces and form counterpublics, where they find support, challenge dominant narratives, and mobilize social activism. While passive engagement in the public sphere may yield negative psychological outcomes, active participation in counterpublics is often associated with more positive effects. The spiral of silence theory further explains how dissenting voices may be muted in hostile environments, and recent models of active versus passive social media use (Verduyn, Gugushvili, & Kross, 2022) underscore the complex interplay between online engagement and well-being.
Methodology:
This research will adopt a systematic literature review framework following PRISMA guidelines. It will synthesize interdisciplinary studies from communication, sociology, and digital media research to critically evaluate theoretical and empirical insights on discrimination dynamics in online environments.

Political Self-Disclosure Online: A Systematic Literature Review
User-generated content lies at the heart of social networking sites (SNSs) and serves as a crucial pillar political discourse. While traditional research on self-disclosure has primarily focused on the privacy calculus, little is known about the broader socio-political aspects—especially when it comes to political content and activism. This project aims to bridge this gap by examining how users weigh perceived benefits and costs when engaging in political self-disclosure online. In addition to exploring the dynamics of public spheres, counterpublics, and the spiral of silence, this research will illuminate how these factors shape political activism and online engagement.
Core Research Questions:
- What factors underpin the socio-political calculus of political self-disclosure on SNSs?
- How do perceived benefits, costs, and cost-mitigating factors influence users’ willingness to engage in political discourse?
- In what ways do public spheres, counterpublics, and the spiral of silence interact to shape political activism online?
Methodology:
This research will adopt a systematic literature review framework following PRISMA guidelines. It will synthesize interdisciplinary studies from communication, sociology, and digital media research to critically evaluate theoretical and empirical insights on political self-disclosure.
Candidate Requirements & Contact:
We invite candidates with strong methodological skills in literature synthesis, familiarity with digital media research, and a passion for exploring social inequality.

Intergroup Contact in Social Media: A Systematic Literature Review
Intergroup contact theory, as pioneered by Allport (1954), has long served as a foundational framework for understanding how interactions between members of different groups can reduce prejudice and foster social cohesion. In today’s digital era, however, the emergence of social media as a central arena for interpersonal communication introduces new dimensions to this classic theory. Digital platforms not only facilitate rapid and widespread interactions but also introduce unique variables—such as anonymity, algorithmic content curation, and platform-specific affordances—that may transform traditional mechanisms of prejudice reduction. This thesis project aims to systematically review and synthesize empirical studies across disciplines (e.g., psychology, communication studies, and information systems) to assess social media intergroup contact.
Methodology:
Adopting a systematic literature review framework in accordance with the PRISMA protocol, this project will critically assess empirical studies from multiple disciplines. This approach aims to distill best practices and theoretical advancements, offering a comprehensive synthesis of current knowledge on intergroup contact in online environments.

Para-social Relationships with AI Agents: A Systematic Literature Review
As AI entities become increasingly integrated into everyday digital life, the nature of human-like interactions with these systems has emerged as a critical area of study. This literature review will synthesize a broad spectrum of research addressing diverse relational dynamics with AI, including teams at work, friendships, parasocial one-sided engagements, romantic relationships, and intergroup contact. By mapping theoretical frameworks and empirical findings from media psychology, social psychology, and human-computer interaction, the review will identify both commonalities and divergences in how these interactions are conceptualized and measured.
Methodology:
The project will undertake a systematic literature review in accordance with established guidelines (e.g., PRISMA). It will synthesize findings from diverse fields—including media studies, political communication, and computational social science—to map out the mechanisms and consequences of hate-inducing disinformation. Special emphasis will be placed on content analysis methodologies to understand both the relationship between humans and AI agents.

Para-social Relationships with AI Agents (Master)
In today’s digital ecosystem, intimate conversational and romantic AI models—such as Replika, Snapchat’s My AI, Celebrity AI, and platforms like Fanvue—are enabling users to forge unique, one-sided bonds. These parasocial relationships can provide emotional support and validation while potentially contributing to loneliness, dependency, or a decline in offline social interactions. Recent technological advancements have rendered these AI systems increasingly sophisticated, blurring the lines between simulated interaction and human connection. This evolution necessitates a deeper exploration of how such interactions influence psychological well-being and the fabric of offline relationships.
Possible Methodology:
- Experience Sampling: Capture real-time data on users’ experiences and emotional responses during interactions with these AI systems.
- Semi-Structured Interviews: Conduct in-depth interviews with users to gain detailed insights into the formation, evolution, and impact of these parasocial relationships.
Note: Other methodological approaches may also be viable.
Possible Research Questions:
- How do parasocial interactions with intimate conversational and romantic AI systems influence users’ overall well-being?
- What factors contribute to the formation of these parasocial bonds?
- How do users perceive the benefits (e.g., emotional validation, social support) and drawbacks (e.g., increased loneliness, dependency) associated with these interactions?
- In what ways do these digital relationships affect the quality of users’ offline interpersonal connections?
Candidate Requirements & Contact:
We invite candidates with expertise in qualitative research methods—particularly experience sampling and semi-structured interviews—who are interested in digital media, social psychology, or human–computer interaction.

Para-social Relationship with AI (Bachelor/Master)
In the evolving landscape of social media, the emergence of virtual and AI-driven influencers marks a significant paradigm shift, challenging traditional notions of interaction and influence. This research aims to delve into three critical aspects of this phenomenon: the nature of interactions with AI influencers, the implications of these entities on users' social media well-being, and the dynamics of para-social relationships formed with virtual/AI entities.
Topics may include, but are not limited to, the following
- Social Media Intergroup Contact with Virtual/AI Influencers: The investigation centers on the application of intergroup contact theory to the domain of social media, particularly in interactions involving AI influencers. It seeks to understand the role of virtual or AI entities, designed to mimic human beings in social media, in influencing intergroup relations. The primary objective is to evaluate the potential of AI influencers in reducing prejudice under the framework of intergroup contact theory.
- Well-being in para-social relationsships Social Media with Virtual/AI Influencers: The use of social media can have both positive and negative effects on the well-being of its users. In recent years, the emergence of virtual/AI influencers, who are increasingly indistinguishable from real people on social media platforms, has introduced new dynamics in digital interactions. This study aims to explore the effects of these virtual/AI influencers on the well-being of social media users, examining how their presence may impact mental health, self-perception, and overall well-being in and beyond the digital sphere.
- Para-social Relationships with Virtual/AI Entities: AI entities such as Snapchat's My AI, ReplikaAI and Celebrity AI are designed to form intimate bonds with real people, often targeting areas such as both romantic and friendship bonds while monetizing digital loneliness. The study of this phenomenon addresses the nature of the parasocial relationships between users and these AI agents and aims to understand the psychological dimensions, the impact on users and the wider implications for future human-computer interactions.
These studies represent a comprehensive effort to understand the multifaceted effects of virtual and artificial agents through social media. By exploring these diverse areas, the research aims to provide valuable insights into the complex interplay between virtual agents, para-relationships, and individual well-being.
