Two new facts stand out: 1. 85% of hallucinated citations in preprints are also in the subsequent journal version (thanks, peer review!) 2. Fake cites more likely to use the names of (male) scholars who are already highly cited, creating a fake-citation Matthew effect. arxiv.org/abs/2605.07723

LLM hallucinations in the wild: Large-scale evidence from non-existent citations

Large language models (LLMs) are known to generate plausible but false information across a wide range of contexts, yet the real-world magnitude and consequences of this hallucination problem remain p...

Most papers on sustainable behaviour change implicitly take the perspective of how large businesses or governments can influence individuals. We need more research on how smaller actors can influence larger ones, and influence each other, in impactful and feasible ways: doi.org/10.1016/j.jr...

When you collect data online, are the results from humans or AI? In a project led by Booth PhD student Grace Zhang, we estimate the prevalence of AI agents on commonly used survey platforms: osf.io/preprints/ps... 🧵

Bots have made their way to Prolific experiments. Our lab has stopped online testing of adults entirely now for this reason - we want to know if what we study is real. Probably data collected 2-3 years ago are ok, but moving forward we just can't know. www.pnas.org/doi/10.1073/...

"Machine learning research is not serious research & therefore hallucinated references are not necessarily a big deal, agrees prestigious group of ML researchers" I ❤️ when the titles write themselves But seriously, I don't think there's much to debate statmodeling.stat.columbia.edu/2026/01/26/m...

My editorial approach has always been pretty simple: 1. Is this a good research question? 2. Has an appropriate method been used to answer it? And that is about it.

Oh Canada!

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

Climate Terminology Does Not Matter Across tens of thousands of participants in two large-scale experiments, we found that labeling climate change in different ways had no effect on their stated willingness to act. jayvanbavellab.substack.com/p/climate-te... via @dgoldwert.bsky.social

Climate Terminology Does Not Matter

Our new paper finds that swapping out one climate term for another does not meaningfully change people’s stated commitment to fight climate change

Chegg, notorious resource for student cheating, is mad that Google is copying its answers.

Katherine Stiles@katherinestiles.org · last yr.

Edtech company Chegg has filed a lawsuit against Google and its owner Alphabet, alleging that the search giant’s #AI Overviews hurt its online traffic. According to Chegg, the Overviews retain traffic that historically came to its website, “materially impacting” the company’s revenue and employees.

IMPORTANT: If you live in the United States or Canada, you’ve probably heard Trump‘s constant claim that the United States is “subsidizing” Canada. It’s wrong of course, but here’s the best explanation I’ve seen about how & why it’s wrong. PLEASE WATCH & SHARE IT A LOT. Kudos to Andrew Chang & CBC.

Underreported: Elon just picked the head of NASA—a massive conflict-of-interest that will damage a government entity that he partners with, depends on, and in some cases competes with. The nominated NASA director is a high-school dropout billionaire who is pals with Musk. He has no business at NASA.

JDM pub: Intertemporal choice questions are usually like "Receive $10 now, or $15 next month?" Yet real-life decisions usually involve a mix of negatives and positives. Do mixed-valence questions better predict real-life behaviours? No! go.shr.lc/3OG36rz @yeli.bsky.social @sjdm-tweets.bsky.social

the fallout from the Francesca Gino research misconduct scandal isn't over. @engber.bsky.social writes about how an effort by some of her colleagues to self-audit their work with her ended up raising even more questions — for them personally and their whole field www.theatlantic.com/magazine/arc...

The superendowment effect—research by Winegar and Sunstein finds users would demand $80 to share personal data, but pay only $5 to keep them private. This raises questions over the reliability of WTP/WTA to gauge the welfare significance of giving up or maintaining privacy: https://buff.ly/3Oa5jvr

It’s insane that I got all the way through getting a PhD before I encountered equivalence tests. These should be part of every intro stats curriculum that covers NHST.
