In this episode of Crossing Channels, Richard Westcott (host) talks to Rachel Adams (University of Cambridge) and Tiziana Assenza (Toulouse School of Economics) about who we can trust online, and how misinformation, platforms and AI are reshaping the information environment.

They explore why misinformation is not only about false content, but also about the systems that decide what people see, when they see it, and at what scale.

The conversation examines how people often overestimate their own ability to spot misinformation, why emotional and identity-based reactions make false information spread, and how AI can deepen inequalities between countries with very different levels of regulation, digital literacy and platform accountability.

They also discuss the risks for democracy, children and public debate, the economic consequences of technology-related misinformation, and what governments, platforms, schools and independent institutions can do to build a healthier and more trustworthy online information environment.
