Nice chart from @ourworldindata.org showing the contrast between what Americans die of (heart disease and cancer) v what the US media reports on (homicide and terrorism). This naturally leads to it being trickier to build a fact based world view ourworldindata.org/does-the-new...

Sense of sentience I've revised my blogpost for people who have discovered AI "people"; hopefully it's better (more clear) this time joanna-bryson.blogspot.com/2025/09/sens... #AIEthics #AGI #genAI

And, therefore, there can also not be hierarchy of methods, because it depends on the specific case whether the assumptions are fulfilled.

If this goes through, Berlin, the Hague, Scandinavians and other frugals will take a hard line: insist that budget will be capped at 1% of GDP. And they’ll be right: no need to be constructive if EU budget spending modernisation is dead. EP will have done itself and the Union a disservice.

What is really happening with Bluesky and its moderation? A thread. First, let’s use the accurate word to describe what Jay Graber (the CEO) and others at Bluesky have been receiving: it’s not criticism, it’s *harassment* I’ve seen some of them being harassed for months by deranged people 1/

Attention Bluesky - @noupside.bsky.social & @rachelkleinfeld.bsky.social say, "To avoid irrelevance when they are needed most, experts & nonpartisan analysts must rethink not just their channels of communication but also their theory of influence." Do you agree? What change is most important? 🧵🧪

This is an excellent development – and the fact that the organization will be hosted in Switzerland and not in the US is even better

Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

Competition enforcement protects democracy. Europe's enforcers forgot this. They thought it was "just a side dish" (@cristinacaffarra.bsky.social will remember which top EU enforcer made that daft remark) The same goes for data protection enforcement. We need our enforcers to enforce.

Whoa! Elsevier fired @richardtol.bsky.social, longstanding Editor-in-Chief of the journal Energy Economics. Richard's side of the story should be ringing alarm bells. #EconSky Fraud and cover-up richardtol.substack.com/p/fraud-and-...

Expect more silence from the Royal Society in the face of their most notorious fellow advocating for the overthrow of the democratically elected government of a country he is neither a citizen nor a resident of (yet he is a fellow of their most prestigious learned society).

Can anyone explain why the Government is still doing most of its communications through a website whose owner is now openly rallying the far right to trigger a violent insurrection on our streets?

🧵 The summer of 2025 has been AI's "cruel summer"—wrongful deaths, dangerous therapy chatbots, medical misinformation, facial recognition failures. These aren't isolated glitches but predictable harms from systems deployed without adequate oversight. www.science.org/doi/10.1126/...

🚨NEW RESULTS (w/ Slattery & Nober) - When gov't engineers retire, highway projects cost more: the engineers pay for themselves 6 times over - Improving gov’t engineer quality from the 25th to 75th percentile reduces costs by 14%, equal to 3x avg. engineer pay Paper: papers.ssrn.com/sol3/papers....

If this goes to SAMP/T and not Patriot, I think it’s safe to say we’ve seen the first major arms deal where Trump has been seen as a greater liability than the benefit of aligning with US equipment would have provided.

Amazing how those democratic lawmakers who were hunted down in their homes in the middle of the night in Minnesota weren’t a watershed moment of political violence, huh?

There is, if you search for it, a group of morally bankrupt and historically illiterate people on here celebrating. What’s weird about Webb’s claim is that this is also true of X, where you can also see rightwing extremists doing the same, and crucially *you don’t have to search for either*.

As we speak, ppl whose humanity I cherish & often consider friends—from leftists to Islamists, LGBTQ activists to devout conservatives—lay murdered underground or in authoritarians’ prisons across the MENA region bc they dared to disagree. Charlie mattered. Free debate matters. A 🧵 on an awful day:

Wrote about the district court judges beginning to express their displeasure with the lawlessness of the Supreme Court's "respect my [unbriefed, unexplained, shadow docket nonsense] authority!" declarations from Gorsuch and Kavanaugh.

Wer sich fuer die Praesentationen der Konferenz "Economy and Power" letzte Woche am @euckeninstitut.bsky.social interessiert - die sind jetzt online (Link im naechsten Tweet). Meine Praesentation zu "Quo vadis, USA?" ist dabei, aber auch die von @tomasoduso.bsky.social dazu, wie man smart

"Die Rente ist kein `Fass ohne Boden´." – Statt Alarmismus plädieren Peter Haan und @jgeyer.bsky.social in der @faznet.bsky.social für eine nüchterne Auseinandersetzung mit den langfristigen Herausforderungen, vor denen unser Rentensystem steht. www.diw.de/de/diw_01.c....

I am surprised that one would even think that he might be an isolationist.

On one hand, reducing car use reduces urban pollution. But on the other, everyone likes it and cities become more livable

Posts about scientific research on Bluesky receive substantially more attention than similar posts on Twitter. More importantly, you're far less likely to get sexist or racist replies.

Using rich multi-level data on US House elections finds that marginal voters tend to favor Democrats. State voting policies have small but sometimes key effects and district maps net favor Republicans, from Steven T. Berry, Christian Cox, and Philip Haile https://www.nber.org/papers/w34149

🇸🇪 Sweden’s wealth tax history shows admin details matter: Saez & Seim found that when only those with wealth above the exemption threshold had to file (1994), many disappeared from the rolls. When pre-populated returns arrived (1997), they reappeared. Filing rules can make or break compliance.

Some are embracing the fantasy that the cuts to #NIH funding will only have an impact here in the USA. As Nature reports, the NIH is the largest global funder by far and dwarfs the rest of the world’s funders of biomedical research. www.nature.com/articles/d41...

"Es gibt massives Lobbying seitens der Finanzbranche", um Maßnahmen gegen den Cum-Cum-Steuerraub zu verhindern, sagt Steuerexperte Christoph Spengel. Ich frage mich, wie ein solches Thema einfach ignoriert werden kann – politisch und auch medial. 2/2 www.sueddeutsche.de/projekte/art...

For some reason I missed that @davidpowell.bsky.social is here on Blue Sky! One econ-pun a day is what your timeline needs. Now.

There are accusations of impropriety against Lisa Cook, a fine economist, once again. Last time (around her confirmation as a Fed Board Governor) the specifics were public and obviously nonsense. This time, they may be buried in lawfare for a while. I stand with Lisa D. Cook.
