I am pleased to announce the publication of "Expectations-based Reference-Dependence and Labor Supply: Eliciting Cabdrivers’ Expectations in the Field" (with Miao Jin, Juanjuan Meng, and Lan Yao), JEBO special issue in honor of Gary Charness. Open access here www.sciencedirect.com/science/arti...

Perhaps half of the papers I was asked to referee this year wouldn’t have passed the desk before LLMs, but now they look OK at first. It takes much more time to tell whether they really should pass the desk. I think this makes the editors’ job harder.

Somewhat funny: before ChatGPT, I had never seen a completely made-up reference. It is the kind of error only an LLM could make.

Colleagues in higher ed: how is your institution responding to AI use? Are there university-wide initiatives for in-person exams, oral exams, and/or AI detection policies? Is the pace of AI so fast that no single uni can realistically keep up? Do you know if universities coordinating their policies?

🧵GPT-5 Pro vs Gemini Deep Think on #gametheory round 2: 1/ After GPT pro performed better on a novel question, I tried something simpler: essentially a “database-style” lookup query. The answer is known and exists in the literature: no reasoning required.

👋 Hi! Time Perception researcher here. Emotional time dilation has been studied pretty extensively with some neat findings. (I recognize OP was meant as joke but this is what I do). Check out my recent Psyche article if curious psyche.co/guides/how-t...

As a physicist I can easily calculate time dilation from relativistic motion (time slows when you're moving fast) or proximity to a massive object (time slows in gravity) but I have yet to find a solution for emotional time dilation (the task takes five minutes to complete but six weeks to start) 🫠

Not bad for a deeply innovative platform with very limited resources, if you ask me

The frustration of making mistakes in chess is much like the frustration of making typos or missing obvious points when writing a research paper. You often find yourself asking: "How could I miss something so trivial? I'm so silly." 1/3

Somewhat strange coincidence: Gemini also solves IMO questions 1-5 but gives no answer to Q6. Curious why neither ChatGPT nor Gemini attempted it. If the methodology holds (still unknown), this could be an important milestone. deepmind.google/discover/blo...

From time to time I like to video myself solving maths problems in real time. Since the IMO has just happened, I plan to try a few of this year's questions. Here I get through Question 1. More to come at some point. www.youtube.com/watch?v=1G1n...

I'm currently looking into the impact of GenAI and LLMs on the social sciences, especially classification tasks. If I can think of some work, especially from a philosophy of scientific practices perspective, I would be happy if you could put it into the answers. Thank you! #philsky #philtech

Once a machine reaches AGI, it almost inevitably becomes ASI with scale because no human can compete with a machine's knowledge base

When Sir Demis Hassabis uses your definition of machine consciousness for AGI 😅 A machine achieves consciousness when it becomes too costly for experts to prove otherwise. "real AGI should be so strong that it would take experts months to spot a weakness" See bsky.app/profile/mehm... 📷 Haider/X

My lifelong habit of using emdashes but typing them as "--" has accidentally become a hallmark of authenticity in the age of AI.

Is it just me, or does it seem like OpenAI for the first time didn't manage to undercut or quickly respond to Google's AI update? It's probably too early to tell, but it could be an early sign that the leadership might be shifting

I wrote a puzzle for @newscientist.com in a column advised by @robeastaway.bsky.social I thought I'd have to pay for it, but I was happily surprised when I learned they wanted to pay me!

"Why work on X, company Y already has it?" Well does the public have it? Do we know how they do it? Are we sure they're doing it the best way possible?

Maybe journals should have a policy that data from anonymous sources will be verified by the journal before publication. The editor could contact the firm, to verify that it exists and that the study was conducted as stated. @aeadata.bsky.social is this feasible or am I missing something?

Papers might as well declare "Data available upon victory in a duel."

"What is it about walking, in particular, that makes it so amenable to thinking and writing? The answer begins with changes to our chemistry. When we go for a walk, the heart pumps faster, circulating more blood and oxygen not just to the muscles but to all the organs—including the brain"

IMO, this is one of the most interesting and promising directions
