Why do we choose what we choose?

University of Cambridge

In this episode, Richard Westcott is joined by Simone Schnall, Catherine Molho, and Maximilian Müller to explore a big, everyday question: why do we make the choices we do? From decisions about money and morality to careers and relationships, the conversation digs into what really drives us—whether it’s emotions, social pressure, or the stories we tell ourselves after the fact. The conversation explores how physical experiences and emotions like fear or anger can shape our judgement, and how gossip and social norms influence who we trust and how we act. Our experts also discuss how we reshape memories to fit our choices, and how identity can shape what we believe or invest in. It’s a fascinating look at what really drives human behaviour—and what that means for how we design policies, technology, the systems we live in, and the role AI might play in shaping our decisions. This episode is hosted by Richard Westcott (Cambridge University Health Partners and the Cambridge Biomedical Campus), and features experts Catherine Molho (IAST), Maximilian Müller (TSE) and Simone Schnall (Cambridge University).
