In this episode, Richard Westcott is joined by Wendy Ayres-Bennett and Benjamin Pitt to explore a big, everyday question: what is the value of speaking other languages? The conversation looks at how the languages we speak shape our sense of identity, influence how we think and reason, and affect how we relate to others. We explore how multilingualism can foster social cohesion, support cognitive flexibility, and even boost economic opportunities.

Our guests discuss why language is never just a tool for communication and why recognising its deeper value matters for how we design education, shape public policy, and navigate life in an increasingly interconnected world.

This episode is hosted by Richard Westcott (Cambridge University Health Partners and the Cambridge Biomedical Campus), and features experts Benjamin Pitt (IAST) and Wendy Ayres-Bennett (University of Cambridge).

Richard Westcott is an award-winning journalist who spent 27 years at the BBC as a correspondent/producer/presenter covering global stories for the flagship Six and Ten o’clock TV news as well as the Today programme. Last year, Richard left the corporation and he is now the communications director for Cambridge University Health Partners and the Cambridge Biomedical Campus, both organisations that are working to support life sciences and healthcare across the city. @BBCwestcott

Benjamin Pitt is a cognitive scientist and current Research Fellow at the Institute for Advanced Study in Toulouse. He studies how language and culture shape the way people think, and what this cognitive diversity can tell us about the structure of the human mind. He holds degrees from Brown University and the University of Chicago, and – starting next Spring – he will be joining the Department of Psychological and Brain Sciences at the University of Massachusetts, as assistant professor and director of the “Cognitive Construction” lab.

Wendy Ayres-Bennett is Emerita Professor of French Philology and Linguistics, University of Cambridge. She was Principal Investigator (2016-2021) on the AHRC-funded, multi-disciplinary research project, Multilingualism: Empowering Individuals, Transforming Societies, which promoted the value of languages for key issues of our time and explored the benefits of language learning for individuals and societies. An AHRC-funded follow-on project Promoting Language Policy provided research-based evidence for moving languages higher up the political agenda. She currently holds a Leverhulme Trust Emeritus Fellowship to write a book on language policy in the UK.

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).

Maximilian Müller is a behavioural economist at Toulouse School of Economics where he studies questions in fields such as education, development, and family economics. In his research, he examines social influences on individual behavior and beliefs around big life decisions such as career or fertility choices and explores their potential consequences for society-wide outcomes such as intergenerational transmission and social mobility.

Simone Schnall is the Director of the Cambridge Body, Mind and Behaviour Laboratory and Fellow of Jesus College at University of Cambridge. By combining insights and methods from social psychology and cognitive science her research explores how thoughts and feelings interact. She aims to understand how people make judgmen

Richard Westcott talks to Jonathan Stieglitz, IAST and Martin White, University of Cambridge, about the global health challenges related to diet and nutrition, the roles of public health policies, cultural practices, and lifestyle changes, while creating sustainable food systems that ensure access to healthy food for all and maintain economic viability.

How do we address global health challenges, particularly in relation to diet and nutrition? What role do public health policies, cultural practices and lifestyle changes play in shaping our food choices? How can we create food systems that ensure everyone has access to healthy and sustainable food while maintaining economic viability?

To explore these issues, Richard Westcott talks to Prof Martin White, Professor of population health research from the University of Cambridge, and Prof Jonathan Stieglitz, IAST Scientific Director.

Prof Jonathan Stieglitz is an anthropologist specializing in human health and aging. He studies how evolved human biology interacts with variability in the environment to influence well-being over the life course. Since 2004 he has worked with indigenous Tsimane forager-farmers of the Bolivian Amazon, studying how environmental transition (for example, changes in infectious exposures, physical activity levels, or consumption of processed foods) influences diverse health indicators. He co-directs the Tsimane Health and Life History Project.

Prof Martin White is an interdisciplinary scientist who leads research on food systems and public health, and has a particular interest in evaluation of population interventions to improve diet and health. He led the NIHR funded evaluation of the Soft Drinks Industry Levy and currently leads two UKRI interdisciplinary consortia on food system transformation (https://www.mandala-consortium.org/ and https://www.salientfoodtrials.uk).

In this episode, Richard Westcott talks to Diane Coyle, Jacques Crémer, and Paul Seabright about Europe’s position in competing with the US in technology. They explore the factors shaping Europe’s place in the global tech race—how data, policy, investment, competition and culture influence its potential to compete with the US.

Our experts unpack the challenges and opportunities for Europe’s tech ecosystem. They consider whether Europe should aim to catch up with the US or focus on carving out its own path, questioning what success in innovation really looks like. Along the way, they discuss the role of data, risk-taking, the challenges of scaling up new ideas, and the structural and policy changes needed to support innovation in Europe.
