Hey #rstats and #stats people, does anyone know of any references that explain the hazards of trying to run or interpret models with all combinations of many predictors? (i.e., including multiple 2-way and 3-way interactions)

I am hiring a postdoc for a DFF-funded project on social influence, and the decision processes that fuel rich-get-richer dynamics in the online/offline world. The position is for up to a year, competitive Danish salary, remote work possible. Interested or know somebody? DM me or share!

🚨 #DECRA #DE26 announcement: ❗️Outcomes announced publicly for Discovery Early Career Researcher Award 2026❗️ See ARC's RMS for list ➡️ https://rms.arc.gov.au/RMS/Report/Download/Report/a3f6be6e-33f7-4fb5-98a6-7526aaa184cf/285 /bot

The Center for an Informed Public is a bright spot in the current gloom about researching our modern information environment. Definitely encourage early career researchers from all sorts of disciplines to apply.

There is also a slight effect of the secondary source (such as the account posting the claim, as opposed to who is the source of the claim); people were more likely to share claims with an independent consensus, and least so for those with a dependent consensus with the same secondary source.

Next, @scondes.bsky.social is looking at whether repeated presentations of the claim from the same source compared to diverse sources is a vehicle of misinformation. Repetitions lead to greater confidence in the claims, and slightly moreso for those with diverse sources for the claim provided.

🎉 New preprint: Bayesian Competence Inference guides Knowledge Attribution and Information search If someone knows that Venus is the only planet in the Solar System that rotates clockwise, will they also know what Earth’s only natural satellite is? What about which planets have no moons at all?

Hello fellow nerds! The upcoming Australasian Mathematical Psych Conference (AMPC) is going to be on Feb 23-25, and they've just put out the call for abstracts. Details below. This is one of my favourite conferences and this year it's in Singapore(!!) which should be awesome.

FYI, if you are using Zotero, koofr.eu provides a free 10 gb cloud with webdav that could be used for synchronizing pdfs. I tested it this week as I no longer have access to the server I used previously. Seems to work well. koofr.eu/blog/posts/k...

disappointed that @biorxivpreprint.bsky.social is implicitly endorsing the use of LLMs to replace scientific thought @richardsever.bsky.social this is a short-sighted move and a net negative for science

Getting nervous for the talk I'm about to give at a workshop about "using AI to drive impact" which features slides such as these.

Interested in how we make preference-driven decisions, and how this is implemented in the brain? We report that neural correlates of evidence accumulation (CPP, Mu/Beta) are also observed during value-based decisions. www.biorxiv.org/content/10.1... Led by @laurencf.bsky.social (Lauren Fong) 1/n

Hey memory folks! I got a question from a student I couldn't quite answer. I talked about consolidation, and how HM's loss of 3-5 years of recent memories led the field to believe that consolidation might take the same period of time. A student asked - "why would it take so long?"

Do AI agents ask good questions? We built “Collaborative Battleship” to find out—and discovered that weaker LMs + Bayesian inference can beat GPT-5 at 1% of the cost. Paper, code & demos: gabegrand.github.io/battleship Here's what we learned about building rational information-seeking agents... 🧵🔽

Hive mind, I need your help! What are good resources to give to a PhD student to catch up on basic calculus in their own time? For example: logarithms, finding the integral/derivative of a function, basic matrix algebra... High-school level is fine, no need for proofs! #AcademicSky #StatsSky

Very cool study and accompanying @theconversation.com article by @violetchae.bsky.social. Follow her if you’re interested in food, decision-making, and/or cognitive neuroscience!

Can AI simulations of human research participants advance cognitive science? In @cp-trendscognsci.bsky.social, @lmesseri.bsky.social & I analyze this vision. We show how “AI Surrogates” entrench practices that limit the generalizability of cognitive science while aspiring to do the opposite. 1/

How do humans keep inventing tools and technologies that no single person could create alone? Our new preprint, led by @anilyaman.bsky.social & @ts-brain.bsky.social shows that semantic knowledge guides innovation and drives cultural evolution. 🧠📘 arxiv.org/abs/2510.12837

Very excited to share a new preprint that’s been brewing for a long time! This work was led by the exceptional @traceym.bsky.social, and made possible by a developmental + comparative + computational dream team. osf.io/preprints/ps...

A little while ago I wrote a blog post about this work for @spspnews.bsky.social 🧑‍🤝‍🧑👫👭 Check it out here: spsp.org/news/charact...

just finished steve levinson's new book! it's a beautifully articulated argument for social interaction as the evolutionary niche which made language possible, rather than the other way around. progress in linguistics depends on a stronger science of interaction. www.cambridge.org/core/books/i...

📢POSTDOC POSITION ANNOUNCEMENT📢 @nourkteily.bsky.social & I are recruiting a postdoc in the #LitowitzCenter for Enlightened Disagreement. We seek research excellence regarding navigating conflict. Application deadline: Nov. 17. Salary: ~$80k. facultyrecruiting.northwestern.edu/apply/MjQzNw==

We’re hiring! The Berkeley School of Education is hiring a tenure track Assistant Professor of AI and STEM education. Due 10/23. aprecruit.berkeley.edu/JPF05125

One of the most depressing phd experiences is hearing of others' advisors (the ones that are supposed to train us into good scientists) encourage the use of chatbots in lieu of their students' development. thankfully mine don't.

It is a common theme in academia to forget that faculty also get paid to do research and write papers. Getting paid doesn't mean no intellectual contribution to a paper, otherwise unpaid interns would be the only authors on papers.

Excited to finally have my first paper officially published! "How Do Psychology Journals Handle Postpublication Critique?" is now online with AMPPS. Huge thanks to my supervisors @tomhardwicke.bsky.social and @simine.com and co-authors @bethclarke.bsky.social, N Moodie, S Schiavone, and R Thibault ☺️

For all who use Bayesian hierarchical models, have a look at our new preprint, out now together with @linushof.bsky.social @nunobusch.bsky.social and @thorstenpachur.bsky.social osf.io/preprints/ps...

This is an epic paper! I very much enjoyed chatting with @dyamins.bsky.social about the connections between world models and counterfactual simulation.

Once again, ARC hits the 🎯 with their comms strategy: 8pm on Sunday night. When the eyeballs of researchers are glued to … twitter? They've not posted this anywhere else. I can't think of a better way to _not_ "engage stakeholders". Almost uncanny.

Need to backup your Qualtrics? I needed this urgently given a revocation of my Qualtrics account with my former affiliation. Found William Ryan's R code, but it didn't work for me, so I made some tweaks, and it works now. Hope it's helpful to others: github.com/giladfeldman...

5. Today I read a paper by @sabinaleonelli.bsky.social and Alexander Mussgnug that I think illustrates this point perfectly. philsci-archive.pitt.edu/24891/1/Phil...

I'm so jazzed to finally have this paper out with @tagerai.bsky.social in @pnas.org! It's probably my favorite paper I've worked on so far. What happens when punishment is incentivized? 🧵 t.co/y5DUUGTdT9

🚨Pre-print of some cool data from my PhD days! doi.org/10.1101/2025... ☝️Did you know that visual surprise is (probably) a domain-general signal and/or operates at the object-level? ✌️Did you also know that the timing of this response depends on the specific attribute that violates an expectation?

Great time to announce that I am starting an ARC DECRA fellowship here (‪@psychunimelb.bsky.social) in a couple weeks!! 😊

I know it’s gauche to share good news on here, but our university’s IRB (ethics office) just declared that low risk applications will no longer be reviewed by 4 people & then go to a committee. They’ll be reviewed by 1 person. I almost can’t believe a change this positive is possible in this world.
