He didn’t go to sample the Dolcetto d’Alba, I’m fairly sure of that. John Lombe’s mission was industrial espionage. He travelled to Piedmont with the goal of learning the Piedmontese art of spinning silk into strong yarn. Nobody was likely to teach him — that would...
Undercover Economist
My weekly column in the Financial Times on Saturdays, explaining the economic ideas around us every day. This column was inspired by my book and began in 2005.
How did air conditioning become a heated debate?
Keeping warm is sometimes expensive, but even a caveman can cope with the technical challenge: pull on an extra bearskin and throw another log on to the fire. Keeping cool is a trickier business. The eccentric Roman emperor Elagabalus sent his slaves into the...
The UK is stuck in a rollercoaster queue
For those of us frustrated that the UK chancellor Rachel Reeves has been offering the wrong solution to the right problem, there has recently been progress, of a kind: she is now offering the wrong solution to the wrong problem. One of Labour’s key policy goals was to...

Chatbots make stuff up. Why do we believe them anyway?
Marathon day. An early train into London, then an unfamiliar journey across a race-disrupted city from Paddington to Blackheath, all in good time for the start of the race. I was nervous, of course, but was cheered by the sight of another bib-wearing runner — more...
Rage in the age of X
There is a gap between the calm, rational decision-makers we often aspire to be and the overwrought, sentiment-tossed creatures we often are. Rarely is that gap wider than in the political arena. Policy seems like it should be a matter for cool, evidence-based...
Science in the shadow of the Third Reich
In these pages, and in my last book, I’ve written about the lessons we should learn from Richard Doll and Austin Bradford Hill’s investigations in the 1950s into the link between cigarettes and lung cancer. There is one lesson I failed to draw. I wrote that in 1954...
