"Silicon samples" are becoming more and more common in research and polling.
One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.
The updated version of this preprint is now online!

Hey folks, I have such a tool like CodeBot up and running at the Max Planck Institute for Human Development.
We should have a chat, happy to collaborate and lend you our system.
I’ll send emails, too, in case this gets buried.
Perfect

Yet many experts baulk at saying that current AI models display artificial general intelligence (AGI) — and some doubt that they ever will. A March 2025 survey by the Association for the Advancement of Artificial Intelligence in Washington DC found that 76% of leading researchers thought that scaling up current AI approaches would be ‘unlikely’ or ‘very unlikely’ to yield AGI (see go.nature.com/4smn16b).
gee, i wonder why 76% of experts don’t buy into a scientifically bogus idea with nothing but multibillion dollar marketing hype powering it

Peer review is facing a death spiral, and AI production tools are speeding it up. AI-assisted reviewing is necessary and should be open. We built OpenAIReview: open AI reviewing for everyone, for the cost of a coffee.

How does social influence shape collective outcomes? When does it lead to lock-in on inferior options?

We show that often once A becomes even slightly more popular than B, people choose A much more often.

Join us in June at @iast.fr Toulouse for a 2-day workshop on social influence and its large scale implications!
Yessss, this point has been vexing me for some time now. The medical community has specialized risk of bias assessment tools for different study types. Time for the social sciences to step up. Tired of reading garbage in garbage out meta analyses.
📣 Applications for the 23rd Summer Institute on Bounded Rationality are now open!
✨Join us in Berlin @arc-mpib.bsky.social June 08–16, 2026, to explore the topic of “Decision Making in the Age of AI”.

⚠️ Despite all the hype, chatbots still make terrible doctors. Out today is the largest user study of language models for medical self-diagnosis. We found that chatbots provide inaccurate and inconsistent answers, and that people are better off using online searches or their own judgment.

"Boosting metacognition in entangled human-AI interaction to navigate cognitive-behavioral drift"

Happy to see this new work coming to the surface alongside @cabels18.bsky.social @lorenzspreen.bsky.social @lewan.bsky.social and @stefanherzog.bsky.social
🧵
Across seven incentivized experiments and a large reanalysis, we systematically manipulated the presence and type of post-choice feedback in repeated risky decisions to test whether feedback shapes behavior through learning mechanisms or through anticipatory changes in preferences.

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉
We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟
