- Belonging & Belief: The Identity Paradox in Misinformation - Carolin-Theresa Ziemer Why do we believe misinformation, even when facts are clear? Belonging often outweighs truth—but our identities can also help us resist. Three strategies for resilience: inoculation, empathy, and identity building.

- By day seven of SICSS Saarbrücken, participants were in 𝗳𝘂𝗹𝗹 𝗴𝗿𝗼𝘂𝗽-𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗺𝗼𝗱𝗲, diving deep into their collaborative work, even missing coffee breaks. They also presented their initial research questions along with their plans for data collection and analysis.
- In the afternoon, we welcomed @kevinbaum.bsky.social (@dfki.bsky.social) for his keynote: "Ethical Reasoning in the Dark: How to Make Justifiable Decisions When You Don't Know What's Right."
- His provocative talk brought to light some of the biggest 𝗲𝘁𝗵𝗶𝗰𝗮𝗹 𝘀𝗰𝗮𝗻𝗱𝗮𝗹𝘀 𝗶𝗻𝘃𝗼𝗹𝘃𝗶𝗻𝗴 𝘀𝗼𝗰𝗶𝗮𝗹 𝗺𝗲𝗱𝗶𝗮 𝗮𝗻𝗱 𝗔𝗜, sparking reflection and debate on how researchers can responsibly navigate moral uncertainty and highlighting the need for interdisciplinary research.
- On the 6th day of SICSS Saarbrücken, Daniela Braun (@uni-saarland.de) and @rosanavarrete.bsky.social (@uam.es) presented on “𝐶𝑜𝑚𝑝𝑢𝑡𝑖𝑛𝑔 𝑜𝑓 𝑆𝑜𝑐𝑖𝑒𝑡𝑦: 𝑊ℎ𝑦 𝑖𝑠 𝑖𝑡 𝑛𝑒𝑐𝑒𝑠𝑠𝑎𝑟𝑦? 𝐻𝑜𝑤 𝑐𝑎𝑛 𝑖𝑡 𝑏𝑒 𝑑𝑜𝑛𝑒 (𝑡𝑟𝑎𝑑𝑖𝑡𝑖𝑜𝑛𝑎𝑙 𝑎𝑛𝑑 𝑚𝑜𝑟𝑒 𝑖𝑛𝑛𝑜𝑣𝑎𝑡𝑖𝑣𝑒 𝑒𝑥𝑎𝑚𝑝𝑙𝑒𝑠 𝑓𝑟𝑜𝑚 𝑜𝑢𝑟 𝑟𝑒𝑠𝑒𝑎𝑟𝑐ℎ)?” @politicsunisaar.bsky.social @o3pol.bsky.social
- Their lecture was followed by @giucarny.bsky.social and @alexhartland.bsky.social, who continued the discussion by presenting further perspectives and examples on assessing polarization and analyzing the sentiment and topics of political posts.
- We closed our Monday with a thought-provoking keynote by @ridhikashyap.bsky.social (@ox.ac.uk) on “𝐺𝑒𝑛𝑑𝑒𝑟 𝐼𝑛𝑒𝑞𝑢𝑎𝑙𝑖𝑡𝑖𝑒𝑠 𝑖𝑛 𝑎 𝐷𝑖𝑔𝑖𝑡𝑎𝑙 𝑊𝑜𝑟𝑙𝑑.” Her talk highlighted key challenges and opportunities for research at the intersection of gender, demography, and digital data.
- With this, we concluded the lecture and hands-on session part of SICSS 2025. The rest of the week, participants will dive into group projects, applying the techniques and methods learned so far to their own research questions. You can find the materials here: github.com/Societal-Com...

- On the third day of SICSS Saarbrücken, we had the pleasure of learning from @ezagheni.bsky.social (@mpidr.bsky.social), who shared his expertise on “𝑀𝑒𝑎𝑠𝑢𝑟𝑖𝑛𝑔 𝑎𝑛𝑑 𝑢𝑛𝑑𝑒𝑟𝑠𝑡𝑎𝑛𝑑𝑖𝑛𝑔 𝑏𝑖𝑎𝑠 𝑖𝑛 𝑑𝑖𝑔𝑖𝑡𝑎𝑙 𝑡𝑟𝑎𝑐𝑒 𝑑𝑎𝑡𝑎”.
- The session explored crucial topics for handling biases when working with digital trace data, such as how to identify trends over time and filter out biases.
- Emilio also discussed the challenges of surveys and non-representative samples, as well as techniques for calibration and weighting to make digital trace data more reliable. It was certainly a very engaging lecture with many practical examples.
