We have some slots available tomorrow and over the weekend if folks want to test how reproducible their work is! Get a free reproducibility check of your paper: rigor.me I would especially welcome some neuro & ML & econ folks to test this. Throw any weird data at it. Much appreciated ❤️

🚨 Now out in PNAS In decision research, "talk is cheap." We show it isn't. Using LLMs to analyze participants' free-text explanations of their choices, we find verbal reports are a rich, scalable window into how people actually decide. 🔗 www.pnas.org/doi/10.1073/... Led by Kamil Fulawka

Damn! I ran my just-published paper through it and the review was awesome, if a bit humbling. I agree with most of it, and I would have addressed several of the critiques if I had this before submitting. Great stuff!

Usability 10/10 (though of course more speed = more better but I understand this takes time and compute isn't infinite). I will have to carefully check the discrepancies but I immediately understood some of them. Fortunately there was nothing major this time :)

I tried this on one of our papers from 2021. It did a fantastic job! For example (see screenshot) it verified our reported sample size & response rate, and about 80 other reported numbers/statistics with descriptions of where, why, and how some numbers differed.

Like the wallet inspector, but for your data and code. (Kidding, this is very cool and useful)

Sharing our latest endeavour here. How reproducible is your paper? @philipjakobbln.bsky.social and I built rigor.me to ease the burden of computational reproducibility. If you provide a paper, data and code, we execute it and tell you what works (and what fails). Beta is available now: rigor.me

AUTOMATING COMPUTATIONAL REPRODUCIBILITY My colleague @philipjakobbln.bsky.social and I are currently engaged in a research project where we reproduce scientific results en masse. To that end, we built rigor.me, a platform for automatically reproducing papers using agents 🧵

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.

⚠️ 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.

🚨New preprint! 🚨 "Boosting metacognition in entangled human-AI interaction to navigate cognitive-behavioral drift" arxiv.org/pdf/2602.01959 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.
