Today’s bad idea is one with a very long history: David talks to the historian Christopher Clark about antisemitism and the reasons for its endless recurrence. What has made discrimination against the Jews different from other kinds of violent prejudice over the course of European history? How did the ‘Jewish Question’ become the battleground of German politics? Why do so many Christians have a love-hate relationship with Judaism? And where does the state of Israel fit into this story?

In today’s episode about seemingly good ideas gone badly wrong David talks to the philosopher and journalist Kathleen Stock about Facebook Friends, something that was meant to make us happier and better connected but really didn’t. How did online friendship become so performative? Does its failings say more about Facebook and its business models or does it say more about us? And why are academics so susceptible to the madness of social media?

In the second episode in our series on bad ideas David talks to the political economist Helen Thompson about the gold standard, which was meant to anchor the world economy until it all fell apart a hundred years ago. Why does gold so often appear like a stable basis for money in an unstable world – and why not silver? What made the gold standard a source of instability instead?  How can money work if it has no material basis? And is quantitative easing a bad idea as well?
