We are now about a year into the ohmygosh-this-is-for-real stage of the pandemic. A time, perhaps, for taking stock of the big decisions — and whether they were wise. To my mind, there were two big calls to be made. The first: was this virus a deadly enough threat to...
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.

Has the economic clock started to run backwards? The defining fact of economic history is that, over time, humans have been able to produce vastly more of whatever goods and services they value. In The Wealth of Nations, Adam Smith had no doubts that the foundation of...
Late greats: why some brilliant ideas get overlooked
In 1928, Karl Jansky, a young radio engineer at Bell Telephone Laboratories, began researching static interference that might obscure voice transmissions. Five years later, after building a large rotating antenna and investigating every possibility he could think of,...

Has there been a moment in modern history where so many people in free societies have believed such damaging lies? It’s easy to point to the US, where nearly 90 per cent of people who voted for Donald Trump believe Joe Biden’s election victory was not legitimate. No...
Miracle tech that is anything but: a taxonomy of bionic duckweed
Is bionic duckweed a dire threat to our health and prosperity? It just might be. But lest you fear that it is a fresh torment to test us alongside Covid-19, wildfires and murder hornets, I should reassure you that it is not a Triffid-like killer plant. Bionic...
From vaccines to homework, why we humans can’t stop overpromising
