How Reading Made Us: 3. How Reading Made Our Politics Mar 30, 2026

Show notes

Learning to read permanently alters your brain. It changes the emotions you experience and the way you relate to others. When a society learns to read the consequences are dramatic: wars break out, revolutions erupt and new political systems spring into being. Reading made us who we are. With time spent reading - and even reading ability - starting to nosedive, Times writer James Marriott explores how reading changed humanity, and what might happen if we stop.

In this episode James digs into the question of whether literacy led to the invention of democracy, asks whether reading helps us proof ourselves against misinformation, and asks what happens to our politics if reading dies out?

Contributors include - Jung Chang, author - Robert Darnton, historian - Steven Pinker, professor of psychology at Harvard University - Naomi Alderman, writer and presenter - John Burn-Murdoch, chief data reporter for the Financial Times - Nick Harris, ideas editor at the New Statesman - Professor Maryanne Wolf, Director of the Center for Dyslexia, Diverse Learners, and Social Justice at UCLA

How Reading Made Us: 2. How Reading Made Our Feelings Mar 23, 2026

Show notes

Reading seems an unremarkable skill. When we say something is as “easy as ABC”, we mean it is very easy indeed. In fact, learning to read has dramatic and irreversible consequences for people and for societies. Learning to read permanently alters your brain. It changes the emotions you experience and the way you relate to others. When a society learns to read the consequences are dramatic: wars break out, revolutions erupt and new political systems spring into being. Reading made us who we are. With time spent reading - and even reading ability - starting to nosedive, Times writer James Marriott explores how reading changed humanity, and what might happen if we stop.

In this programme, James asks whether the spread of novel reading in the 18th century caused a moral revolution, whether a book played a role in the abolition of slavery, and whether the rise of reading, a solitary and slightly lonely activity, was one of the factors setting us on the path to our atomized and isolated modern society.
