CREATIVITY, or consistency? What is the best recipe for a planet-beating restaurant? In “Finding Grace in a Burger Bun”, in Cautionary Tales with Tim Harford (BBC Sounds), the presenter skilfully compares two fast-food burger empires: one that thrives, and one that has faded away. He examines how cold, calculating capitalism and conformity can yield results; but at what cost?

Mr Harford also portrays the brothers behind the successful franchise as anomalies; they are content with their achievements, and have no desire to push beyond their current needs. I would have liked to learn more about why they did not feel the urge to surge ahead, and, perhaps, how their idea was exploited and was never meant to be more than it was. Nevertheless, the podcast features excellent sound design and effects, immersing listeners in the narrative.

The 11-part documentary “The Irregulars”, in The Secret World of Roald Dahl (Parallax), offers a fascinating look at how Roald Dahl became swept up in real adventures, which he later reorganised and reimagined on the page. Part one focuses on Dahl’s membership of the Irregulars: British spies who operated on the soil of the United States. Dahl charmed his way to the top, becoming a regular guest of the President. Dahl was tasked with encouraging influential Americans to support the war effort in Europe. Ian Fleming, of Bond fame, was also part of the group.

Over the series, we move from Dahl’s farcical and yet successful Bond screenplay to his darker-themed adult short stories. We learn about the many roles that he adopted, from playboy to parent. Dahl poured his triumphs and traumas on to the page, which bled into the children’s literature for which he is best known.

The Revd Raj Bharat Patta, a Methodist minister, reveals the power of Dalit theology as a form of liberation theology, in “Coming Out as Dalit: My story and my testimony”. Subversive Spiritualities: Dalit Theology Month is not widely available, but it can be found on Spotify. Mr Patta tells a personal story of how, growing up as a Dalit, a member of the lowest caste in Indian society, he and his family found that Christianity gave them dignity. He explains how Dalit theology redeems outsiders and places them at the centre of God’s love and action.

There is a widely accepted idea of what an introvert and an extrovert are. Origin Story, “Introvert/Extrovert — In Two Minds”, delves into the history of these concepts and where they originated. It may come as little surprise that ego played a significant part in their development. In fact, the presenters chart the intense battle of egos between Sigmund Freud and Carl Jung — two very different characters, whose dramatic clashes laid the groundwork for our initial understanding of the concepts and the subsequent terminology of “introvert” and “extrovert”. We learn how these terms evolved into what we understand today: the spectrum that we embody versus the binary and unhelpful labelling that we often succumb to. Be advised that there is strong language throughout.
