We welcome Matthew Facciani a researcher at the University of Notre Dame in the Department of Computer Science & Engineering. He is an interdisciplinary social scientist with a PhD in sociology who trained in neuroscience and psychology. His work focuses on misinformation, media literacy, political polarization, social networks, and the influence of AI on belief formation. He is the author of Misguided: Where Misinformation Starts, How It Spreads, and What to Do About It(Columbia University Press, 2025), which explores how false beliefs take hold and what can be done to counter them. In his talk, Matthew will discuss the essential tools needed to fight misinformation—drawing from his research and book to help audiences recognize, resist, and reduce the spread of false information.
