This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

"Vladimir Putin’s administration has endorsed a plan by the Social Design Agency, a Kremlin-linked media consultancy under western sanctions, to bolster Orbán’s Fidesz party by flooding social media with messages designed in Russia and posted by influential Hungarians." www.ft.com/content/34df...

Alphabet, Amazon, Meta, and Tesla paid just 4.9% of their profits in federal corporate taxes in 2025. They have seen their collective tax bill drop by $95B thanks to two rounds of Trump tax cuts. Meanwhile, they've laid off thousands of workers. Trickle-down economics was always a scam.

Maybe we shouldn't have trusted the cigarette companies when they praised the health benefits of cigarettes

America now has 935 billionaires with $8.1 trillion in collective wealth — a 20% increase from 2024. Meanwhile, the bottom 50% of Americans control $4.2 trillion in wealth. When 935 people control more wealth than half a country’s population, we have a very serious problem.

Many of us are struck by the combination of cleverness and pure inanity of many AI answers. Clever on some elaborate questions but not able to perform elementary fractions for instance. Now I better understand the reason: msukhareva.substack.com/p/gpt-52-and...

Interesting. Do we have solid evidence that this is also the case in practice? I'd be happy to show whatever is the evidence in class.

Wow. This is the paper I have been waiting for. Mobile apps are brain rot, with meaningfully bad economic consequences for those who overuse them.

The NRA buys off Congress. No action on guns. The oil industry buys off Congress. No action on climate. Insurance companies buy off Congress. No action on health care. The list goes on and on. Money in politics is the root of our dysfunction.

Horrible migrants are killing Europe, says horrible migrant arriving in Europe

That's interesting : in an RCT, giving AI tools to developers actually slowed them down ! And yet, they are convinced they went faster.

Sad but seems right. Do far we still are dwarf Davids claiming to be Goliath

“Department of Government Efficiency.”

Wow! Three scholars at Columbia, Michigan, & Maryland just introduced a measure of the partisan leanings of employers in the U.S. The data is constructed by linking voter registrations to online worker profiles. VRscores capture the political affiliations of 21.8M workers across 2.6M employers.

New chart just dropped.

For the @economist.com, I wrote about the Le Pen verdict. In liberal democracies, the law needs to be applied even if that strengthens the far right. But here, we should not just assume that this will help the RN. On the contrary. It's a good moment for democracy. www.economist.com/by-invitatio...

I received a heartbreaking email today: A paper in a special issue I’m editing is being retracted because one of its authors is afraid of losing their job and their legal status in the U.S. if they publish a scientific study on evolution. Yes, on evolution, nature's engine of diversity.

Please take a moment to watch this video. Says it as it is. So refreshing.

This is a very interesting experiment. Point 1: it works. Point 2: We have no clue about long-term effects. I knew my way a lot better before GPS. I unlearned that: can there be negative side-effects on human expertise? -- 1/2

Soviet joke Yuri Gagarin’s daughter answers the phone. ‘No, mummy and daddy are out,’ she says. ‘Daddy’s orbiting the earth, and he’ll be back tonight at 7 o’clock. But mummy’s gone shopping for groceries, so who knows when she’ll be home.’ (Source: Francis Spufford) 🧪
