In today’s episode about the power of bad ideas, David talks to historian and podcaster Dan Snow about the myth that wars are settled on the battlefield. Why are we so drawn to the idea of the decisive military showdown? Is Napoleon to blame? What are the forces that actually settle military conflicts? Plus: were Abba really so wrong that Waterloo won the war?

Out tomorrow: A bonus episode in which David and Dan explore a range of battles to see what got settled and what didn’t: Yarmuk, Hastings, Agincourt, Trafalgar, Warsaw 1920, Stalingrad.

Today’s bad idea is ‘genius’, the label that has enabled all sorts of terrible behaviour through the ages. Writer and broadcaster Helen Lewis explains how and why the idea of genius gets misapplied to people and things that just aren’t. Why are geniuses meant to be tortured? Why are individual geniuses prized over the collaborations that lie behind most innovations? Why do we think that people who are brilliant at one thing will be good at everything else? Plus, David makes the case for Dickens as a bona fide genius.

For the first episode in our new series about how bad ideas take hold, David talks to economist Mark Blyth about austerity, the cost-cutting idea that refuses to die. Why is it an article of faith that states need periodic purging to stop them getting too greedy? Why does this so often happen at times when it does most harm, from the 1930s to the financial crisis that began in 2008? And how is the politics of austerity playing out today, in Starmer’s Britain, in Milei’s Argentina and in the DOGE wars happening in Trump’s America?

Today’s political trial is perhaps the most consequential in English history: the trial and execution of King Charles I for treason in January 1649. How could a king commit treason when treason was a crime against the king? How could a court try a king when a king has no peers? How could anyone claim to speak for the people after a civil war when so many people had been on opposite sides? The answers to these questions would cost more than one person his life – but they would also change forever the prospect of holding tyrants to account.

Today’s trial is one of the most notorious in history but also one of the most misremembered. Galileo’s epic confrontation with the Catholic Church over the question of whether the earth moves round the sun – culminating with his interrogation and condemnation in Rome in 1633 – was not just a matter of truth vs ignorance or science vs superstition. It was also twenty-year long struggle on the part of both sides to find a way to co-exist. Did they succeed? Not exactly, but it wasn’t for want of trying. Then – and perhaps now – science and religion needed each other.

Today’s episode is about a pivotal event in British history that took place exactly 50 years ago: the 1975 referendum on Britain’s membership of the European Community. David talks to historian Robert Saunders about why it was so different in so many ways from the Brexit referendum in 2016. Why in 1975 were Labour and the SNP the Eurosceptic parties? What made the Tories pro-European? Where was immigration as an election issue? How did the Yes campaign overturn a big deficit in the polls? Plus: why didn’t it settle the question, so that another referendum had to be held four decades later?

Available tomorrow on PPF+: Part 2 of this conversation in which David and Robert try to make sense of the many differences between the 1975 and 2016 referendums as well as exploring where Britain stands in relation to Europe in 2025.

In today’s episode an extraordinary political trial that culminated in the execution of one queen at the behest of another: Mary Queen of Scots, convicted of treason in 1586 and beheaded in 1587. But who really wanted her dead, Queen Elizabeth or Elizabeth’s powerful political servants? Why did Mary demand to be tried before parliament rather than a court of noblemen? How did she attempt to defend herself in the face of apparently overwhelming incriminating evidence against her? And who was the only person who voted for her acquittal?

In today’s episode another trial that forms the basis for great drama: the case of Thomas More, tried and executed in 1535, events dramatised by Robert Bolt in A Man for All Seasons and Hilary Mantel in Wolf Hall. How did More try to argue that silence was no evidence of treason? Why was his defence so legalistic? Was he really ‘the Socrates of England’? And who was the true villain in this case: Thomas Cromwell, Richard Rich or the King himself?

Today’s political trial took place in 1431 though it was still being re-litigated right through to the twentieth century: the case of Joan of Arc, charged with heresy by the Church and burned at the stake. Why was a political prisoner tried in an ecclesiastical court? Why were her interrogators so obsessed by her choice in clothes? How did Joan seek to explain her visions? And was this trial any more of a fix than the later trials that exonerated her?

The first political trial in our new series is the one that set the template for all the others: the trial of Socrates in Athens in 399 BCE, which ended with a death sentence for the philosopher and a permanent stain on the reputation of Athenian democracy. Why, after a lifetime of philosophy, was Socrates finally prosecuted at the age of 70? Was the case motivated by private grievance or public outrage? What should Socrates have said in his own defence? Why, in the end, did he choose defiance instead?
