Social Media Literacy: Entwicklung einer Browser Extension zur Erkennung und Bewertung maschinell generierter Inhalte auf X

This thesis explores how a real-time bot detection browser extension can influence Social Media Literacy and critical thinking among personal users on the platform X. As misinformation increasingly spreads through social bots, users require tools that not only detect inauthentic accounts but also support informed decision-making. To address this, a browser extension was developed that integrates visual indicators directly into the X timeline. Using these and a contextual side panel, it provides immediate feedback on account authenticity while incorporating Explainable AI principles to maintain user autonomy and transparency.The study employed a three-phase qualitative methodology: a pre-assessment using think-aloud protocols and interviews to understand user behavior and expectations, a development phase informed by user feedback, and a final evaluation with the same participants. Findings show that the extension increased awareness of bot behavior, supported more cautious media consumption, and fostered critical evaluation skills but also cause overreliance in some cases.The results contribute to the field of Social Media Literacy by demonstrating that real-time interventions can positively influence how users assess content credibility. The thesis highlights the potential of AI tools to support digital literacy while underscoring the risks of overreliance. Future research should explore long-term effects and broader platform applicability to ensure sustainable literacy development.
