Abstract:
What affects online discourse and how can we improve it? Researchers and practitioners have been looking for ways to combat the spread of problematic content online. One promising intervention involves prompting users to think about the accuracy of the information before sharing it. We used computational modeling (inspired by random walk models of human decision making) to show that the intervention (6 experiments, 5,633 participants) is effective because it shifts people's attention to accuracy (but did not make them deliberate more). We then conducted three Twitter field experiments (N = 75,763) and a Facebook experiment (N = 33,043,471), which found showing users accuracy-prompt ads about three times per day reduced misinformation sharing by up to 6.3%. I'll also mention a recent experiment (N = 89,794) with collaborators at the World Bank where we focused on reducing ethnic hate and conflict on Nigerian X and quantifing network spillover effects (i.e., whether the treatment effect on treated users is also observed on these users’ followers). Finally, I'll briefly discuss ongoing projects related to lab and field experiments with large language models using a platform I built (https://www.vegapunkdoc.dev).

Speaker Bio:
We make countless decisions every day and often want our choices to lead to good outcomes for ourselves, others, and society. So, why do we often make bad decisions? My research seeks to understand and improve decision making by using an interdisciplinary approach that spans multiple levels of analysis—linking the mind, brain, and behavior—that intersect cognitive science, computational social science, and complex social systems. I complement it with a rigorous, integrative empirical strategy: I conduct survey, laboratory, and field experiments to test theories, evaluate interventions for changing decision making "in the wild," and ensure my research is internally and externally valid. My theoretical and methodological approach pushes the frontiers of social and cognitive science theories, facilitates interdisciplinary collaborations, and tackles issues affecting individuals, societies, and policies.

Happy International Greek Language Day!

Happy International Greek Language Day!

9 February 2025

Today, we celebrate the historical, cultural, and linguistic significance of the Greek language. While Standard Modern Greek often takes center stage, we at Archimedes - AI and Data Science Research Hub recognize the impressive diversity and great cultural significance of its numerous dialects. These dialects present both exciting opportunities and complex challenges for AI and Large Language Models (LLMs) because each one of them presents unique linguistic features and all of them are low resourced. That’s why we’re using cutting-edge AI to document, digitize, and analyze these invaluable linguistic treasures, ensuring their preservation and accessibility for generations to come.
