"Why doesn't my kid stop dropping his pizza on the floor and laughing?" That puts his repeated remarks about ChatGPT's PhD-level intelligence into perspective.
Jimmy Fallon: "And do you use ChatGPT when raising your baby?"

Sam Altman: "I cannot imagine figuring out how to raise a newborn without ChatGPT."

I love Pluribus.

What do people think about IJCAI's Primary Paper Initiative ($100 paper submission fee, first submission is free)? The proceeds will be "exclusively directed toward the support of the reviewing community".

After Russia 2018 and Qatar 2022, FIFA gives us Trump 2026.

And 8 of the 12 teams that place 3rd will also advance to the knockout round. The group stage will be a farce.

Oh right. I didn't realize they had been absent since 1998!

They participated four times when there were only 4 groups 😊 Four-time champion Italy is still not qualified 😧

Until 1982, there were 4 groups at FIFA World Cups. Having 12 groups is just ridiculous. Germany is facing Curaçao, the smallest nation ever to participate in a World Cup. They have a population of approximately 150,000, comparable to cities such as Heidelberg, Darmstadt, and Ingolstadt.

All these acronyms appear in his 1986 book "The Logic of Collective Choice".

Political scientist Thomas Schwartz (✝ 2024) surely had a great sense of humour when it came to acronyms:

GEneralized Top CHoice Assumption (GETCHA)
Generalized Optimal CHoice Axiom (GOCHA)
SOlution COndition (SOCO)
MUltiSTAge CHoice operation (MUSTACH)
BInary-CHoice property (BICH)

Great series of primers on democracy reform that specifically address problems in the US: the electoral college, private fundraising, gerrymandering, unavailability of vote-by-mail, first-past-the-post (plurality), etc.
Don't miss the article about Condorcet voting.

Probably, but I don't have a link at hand.

Nice survey on how to vote on divisible resources (such as budget, space, or time)

Interesting German article that proposes using a Condorcet-consistent method for Bundestag elections.

Nowadays, every single AAAI publishes more papers per year than have ever appeared in, say, Social Choice and Welfare (ca. 2k papers since 1984) or Games and Economic Behavior (ca. 3k papers since 1989). There’s just no way that so many papers deserve to be published. In any area.

AAAI 2026 has received more than 29k submissions. Peer-reviewing is completely broken for AI. It’s not only the well-documented issues, such as self-nominated PC members, mismatched referees, useless reports, fraudulent submissions, low-quality papers, etc.

Today's post by the single finest Nobel Peace Prize candidate ever.

That one's even better.

Ironically, the biggest obstacle to broader adoption of LLMs seems to be their lack of reliability, a trait that is otherwise characteristic of computers.
Like the worst of us, they just make up facts rather than admit they don’t know. I appreciate anyone who admits they don’t know something.

Borda strikes back.

Very impressed by ChatGPT4o's new and improved image generation capabilities.

Really hard to tell April Fool's jokes from genuine news this year.
US regrets that far-right extremist Marine Le Pen is convicted of fraud. Trump abandons money laundering law. Musk pays millions to Wisconsin voters. Innocent father from Maryland accidentally deported to El Salvador mega prison.

Happy to see that people in machine learning (ML) are drawing on results from social choice theory. Especially maximal lotteries (ML) are getting some attention because of their robustness against clones. I recently compiled a topical bibliography of my ML papers: www.cs.cit.tum.de/en/dss/brand...
