Foolproof: How to Build Resistance to Misinformation

In this episode of Misguided: The Podcast, I’m joined by Sander van der Linden, who is a professor of social psychology at the University of Cambridge and one of the leading researchers studying misinformation, propaganda, and how people can build resistance to manipulation. If you’re familiar with the idea of “prebunking,” or psychological inoculation (training people to recognize misinformation before they encounter it), much of that work traces back to Sander’s research.

We begin by talking about his non-traditional path into psychology, from leaving a banking job to discovering research as a career, and how early experiences with being misled sparked a deeper interest in influence and propaganda. From there, we dig into what psychological inoculation actually is, why simply giving people facts often isn’t enough, and how tools like the Bad News game help people recognize manipulation techniques across political and cultural contexts.

We then zoom out to the broader information ecosystem, including the economics of fake social media accounts and how cheap it has become to spread inauthentic activity at scale, especially in an age of AI. Finally, we discuss what effective responses might look like, from education and platform responsibility to why Sander remains cautiously optimistic despite the very real challenges ahead.
