Why Modelling Misinformation is Not Social Physics

This was a talk delivered in March 2026 for the Institute of Physics, as part of the IOP London and South East Physics Talk Series.
In the age of AI, misinformation is a serious concern, threatening health, climate, and democracy. The Royal Society-funded PolyGraphs project simulates its effect on public opinion. This talk sketched findings from this research in computational philosophy, and explained how it differs methodologically from the physics of complex systems.
