The Weekend of Mistakes 2026

In a world brimming with shocks, surprises and uncertainty, this year’s programme asks how earlier generations navigated similarly unstable times— and what we learned (or didn’t) from them. After all, every mistake was once somebody’s brilliant idea — a reminder that even failure has its moment of conviction.

Across the Castle, intimate, close-up conversations offer a chance to listen and to chat. This year’s sessions include:

  • The mafia’s unlikely role in shaping 1960s queer nightlife
  • The economics of football - and why Hollywood is investing in the UK’s lower leagues
  • Forgiveness, faith traditions and the morality of debt
  • Gen Z’s pension prospects as young taxpayers
  • Why your water bill is so high - and how to fix it
  • ‘Trumponomics’ and the new age of state capitalism
  • Who decides the future of entertainment
  • What happens when financial stress becomes a mental health crisis?

At the heart of the weekend is Default: the history, art and ethics of not paying back what you owe — a timely exploration of the world’s growing mountains of debt, and the moral accounting of the ‘promise economy’ from personal crises to global fault lines.
