The Weekend of Mistakes 2026

We’re putting the finishing touches to our programme for 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.

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 dark side of the world’s growing mountains of debt, and the moral accounting of the ‘promise economy’ from personal crises to global fault lines.

But it’s not all doom and default. Elsewhere, we’ll be asking why your water bill is so high, exploring the allure of investment “havens”, and why Wrexham, of all places, is suddenly the centre of the (football) world. We’ll consider whether ‘Trumponomics’ is state capitalism or straightforward shakedown, consider the newly emerging economics of conflict, and take well informed looks at energy, markets and investment.

Full programme coming soon...

A Weekend that was definitely not a Mistake! I greatly enjoyed the wonderfully warm atmosphere that blurred the boundaries between the audience and the speakers. A wonderful event and brilliant for everyone to share ideas and expertise in this relaxed atmosphere.
