Tim Harford investigates some of the numbers in the news. This week:
Nigel Farage says 6.5 million people are on out-of-work benefits – with some benefits up 80% since 2018. Are those numbers right?
Do French pensioners really earn more than their working-age compatriots?
How is it possible for one kilogram of fish food to produce one kilogram of salmon?
And do we really have five senses?

Have you ever stopped to think about how your morning cappuccino came to be? From the coffee bush that yielded the beans, to the grass for the cattle – or perhaps the soya – that produced the milk, plants are an indispensable part of our everyday life.
Beginning with some of the earliest uses of plants, in 50 Plants that Changed the World (Bodleian, 2025) Dr. Stephen Harris takes us on an exciting journey through history, identifying fifty plants that have been key to the development of the western world, discussing trade, imperialism, politics, medicine, travel and chemistry along the way. There are plants here that have changed landscapes, fomented wars and fuelled slavery. Others have been the trigger for technological advances, expanded medical knowledge or simply made our lives more pleasant. Plants have provided paper and ink, chemicals that could kill or cure, vital sustenance and stimulants.
Some, such as barley, have been staples from earliest times; others, such as oil palm, are newcomers to western industry. We remain dependent on plants for our food, our fuel and our medicines. As the wide-ranging and engaging stories in this beautifully illustrated book demonstrate, their effects on our lives continue to be profound and often unpredictable.
This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

FBI Director Kash Patel spoke on Tuesday about a massive rise in the number of investigations into so-called NVEs, which stands for “nihilistic violent extremists.” He defined them as people who“engage in violent acts motivated by a deep hatred of society.” Some experts would use that term to describe the suspect in the Charlie Kirk shooting. Utah prosecutors said Tuesday that the suspect allegedly wrote video game references and online jokes on the bullet casings. We’ve chosen not to reference the name of the alleged shooter because we think it’s important not to give people who commit acts of violence the infamy they crave. To talk more about the online spaces where Charlie Kirk’s alleged shooter spent most of his time and the rise of NVEs, we spoke to David Gilbert, who covers disinformation and online extremism for Wired Magazine.
And in headlines: President Donald Trump is suing the New York Times again, Israel officially launches its ground offensive in Gaza City, and former Centers for Disease Control and Prevention director Susan Monarez testifies to a Senate panel about her ouster by Health and Human Services Secretary Robert F. Kennedy Jr.
We discuss the assassination of Charlie Kirk and its potential role as a catalyst of further violence and blowback by right-wing forces who want to avenge a martyr, by left-wing groups who want to kick off years of lead, or perhaps as simply another immense yet ephemeral moment in a strange world where “our whole life is surrounded by an immense accumulation of spectacles.” Then we segue expertly to talking about a new essay on “the weaponized world economy,” which adds great detail and depth to our analysis of the geoeconomic dynamics and conflicts that drive global politics, markets, finance and technology.

On this episode, Nathan Goodman is joined by Michael Clemens to discuss why immigration policy matters not just for migrants themselves but for broader economic growth. Drawing on his influential work, including “Economics and Emigration: Trillion-Dollar Bills on the Sidewalk?” (JEP, 2011) and “The Place Premium: Bounding the Price Equivalent of Migration Barriers” (REStat, 2019), Clemens explains how even modest liberalization of migration can create enormous gains, why exchange is positive-sum, and how complementary skills across the workforce drive production. Together they assess the claim that immigration undermines culture and institutions and revisit historical panics ranging from the Chinese Exclusion Act to the Dillingham Commission.
Dr. Michael Clemens is a professor in the Department of Economics at George Mason University and a Non-Resident Senior Fellow at the Peterson Institute for International Economics. He helped build the research program on international migration at the Center for Global Development.
