Auch wenn die Zahl der Verbrechen sinkt, kann die Angst vor Kriminalität zunehmen – etwa in Zeiten gesellschaftlicher Umbrüche und größerer Terroranschläge in Europa.

Crazy, but that's how it goes
Millions of people living as foes
Maybe it's not too late
To learn how to love

In Quinton v. Amex, 2025 WL 1994848 (EDNY 7-7-2025) the court admitted testimony that Amex's anti-steering rule was unlawful "cross-subsidization" -- a rare case permitting theory that a pure wealth transfer from poorer to wealthier customers could be an antitrust violation.

Ministerin Bär ist gerade auf gutem Weg, das Vertrauen der dt. Wissenschaft in ihr Ministerium zu verspielen, indem sie öffentliche Diffamierung einer Wissenschafterin verharmlost & dabei auch noch der Angegriffenen Schuld zuschiebt. Schutz der Wissenschaft wäre ihr Auftrag & sie tut das Gegenteil.🤯

To honour the memory of Ghazala Azmat, the Department of Economics of SciencesPo is creating an award in her name.

Can an AI model predict perfectly and still have a terrible world model?

What would that even mean?

Our new ICML paper (poster tomorrow!) formalizes these questions.

One result tells the story: A transformer trained on 10M solar systems nails planetary orbits. But it botches gravitational laws 🧵

Nochmal zur Kampagne gegen Brosius-Gersdorf

Das Problem ist ja nicht allein, dass mit falschen Vorwürfen hantiert wird

Das Problem geht tiefer: Selbst wenn Medien dann Faktenchecks machen, spiegelt sich darin das Kern-Framing der Kampagne wider, das eine Expertin als fragwürdig umdeuten versucht

Victory for Trump as EU backs down on digital taxes in next budget Shelving the plan could help EU persuade the U.S. to give it a more favorable trade deal and comes just two months after the Commission suggested it.

Another potential EU own resource quietly taken off the table.

No surprise, given the state of transatlantic talks - but underscores how difficult closing the EU's budget gap will be without higher national contributions.

This is a fairly technical but highly relevant paper on how we can model complex systems at various levels of detail without losing causal content. Think gas: instead of tracking every molecule, we can focus on big-picture properties like temperature and pressure. www.auai.org/uai2017/proc...

Walking on campus, I was just thinking how hard it is to be a grad student. It was by far the hardest thing I have done professionally, and there were many days (and nights!) when I was certain I would never come up with a job market paper (or, any paper, really). Grad students, hang in there!🤗
