Thinking Allowed

When, where, and who gets to touch and be touched, and who decides? How does touch bring us closer together or push us apart? These are urgent contemporary questions, but they have their origins in late nineteenth and early twentieth-century Britain. Laurie Taylor talks to Simeon Koole, Senior Lecturer in Liberal Arts and History at the University of Bristol about his new study of the way in which the crowded city compelled new discussions about touch, as people crammed into subway cars, skirted criminals in London's dense fogs and visited tea shops, all the while negotiating the boundaries of personal space. How did these historical encounters shape and transform our understanding of physical contact into the present day? Also, digital touch. Carey Jewitt Professor of Technology at the Institute of Education, London, explores the way technology is transforming our experience of touch. Touch matters. It is fundamental to how we know ourselves and each other, and it is central to how we communicate. So how will the the digital touch embedded in many technologies, from wearable devices and gaming hardware to tactile robots and future technologies, change our sense of connection with each other. What would it be like if we could hug or touch digitally across distance? How might we establish trust or protect our privacy and safety? How might radically different forms of touch impact our relationships and the future? Producer: Jayne Egerton

Laurie Taylor explores the fascination for true crime stories. He's joined by Jennifer Fleetwood, Senior Lecturer in Criminology at City, University of London, whose latest work considers the remarkable rise in the number of people who speak publicly about their experience of crime. Personal accounts used to be confined to the police station and the courtroom, but today bookshops heave with autobiographies by prisoners, criminals, police and barristers while streaming platforms host hours of interviews so how easy is it for the 'truth' to come out? Louise Wattis, Assistant Professor in the Department: Social Sciences ·at Northumbria University, Newcastle looks at the skyrocketing interest in true crime as a form of popular entertainment. What do we know about the appeal of 'Hardman' biographies of violent criminals, a hugely popular subgenre, particularly for male readers? Producer: Jayne Egerton

After the Second World War, a vast experiment took place in which adventure playgrounds transformed bombsites and waste ground in the UK, creating opportunities for children, beyond the sanitised safety of more conventional play spaces with swings and see saws. Laurie Taylor talks to Ben Highmore, Professor of Cultural Studies at the University of Sussex about the range of people whose celebration of children's imaginative capacities re-invented the notion of play, from Northern Europe to North America. Designers, social reformers, and even anarchists, saw these sites of fun as the foundation for the creation of citizens and agents of social change. What remains of those post war playgrounds, in the here and now, and what can the astonishing ambition of those spaces tell us about the power of play in an age of risk aversion?

Laurie Taylor lifts the lid on a sector of the economy associated with wealth, innovation & genius. Mark Graham, Professor of Internet Geography at the Oxford Internet Institute, uncovers the hidden human labour powering AI. His study, based on hundreds of interviews and thousands of hours of fieldwork, is the first to tell the stories of this army of underpaid and exploited workers. Beneath the promise of a frictionless technology that will bring riches to humanity, the interviews he has conducted reveal a grimmer reality involving a precarious global workforce of millions labouring under often appalling conditions. Also, Paula Bialski, Associate Professor for Digital Sociology at the University of St. Gallen in St. Gallen, Switzerland, discusses her research with software developers at a non-flashy, run-of-the-mill tech company. Beyond the awesome images of the Gods of Silicone Valley, she finds that technology breaks due to human-related issues and staff are often engaged in patch up and repair, rather than dreaming up the next killer app. Producer: Jayne Egerton

Laurie Taylor talks to Ann Murcott, Honorary Professorial Research Associate, at SOAS, University of London about the origins and development of food packaging, from tin cans and glass jars to bottles and plastic trays. How central is packaging to global food systems and should we be concerned about wasteful packaging ? Also, Anastacia Marx de Salcedo, offers a spirited defence of processed food from a feminist, economic, and public-health perspective. Producer: Jayne Egerton
