When does using AI to produce research slip into fraud? And why does so much AI-for-science 'optimism' actually rest on a deeply pessimistic view of scientific agency? 🤔 New post: statmodeling.stat.columbia.edu/2026/04/22/f...

🚨🚨JOB ALERT🚨🚨 I'm hiring a cogsci/philosophy/compneuro postdoc at @ucl.ac.uk @uclbrainscience.bsky.social @uclpals.bsky.social! www.jobs.ac.uk/job/DRH486/p... Come to London & work on frameworks for "testing" for consciousness using Bayesian belief updating & latent variable modeling. Pls share!

Good news everyone 🥳 Our (w @vincentab.bsky.social) primer on models as prediction machines (with the marginaleffects package) is finally officially published!> journals.sagepub.com/doi/10.1177/...

my cat and I both really enjoyed this fantastic interview on animal/AI sentience! in it, @birchlse.bsky.social grapples with so many difficult & pressing questions while making room for genuine progress to be made

This is a noteworthy specific instance of a more general tension I wrote about last year and continue to think about: sootyempiric.blogspot.com/2025/09/on-t...

The first few articles in this collection are now published, including ours. I look forward to reading all. Our piece is not open access because of the ridiculous fees but the preprint linked at the end of the quoted thread (will link again below) is the accepted version of our commentary.

People sometimes say that an outcome was caused by two things. We might say Amy got sick because (a) There was cilantro in the soup *and* (b) Amy is allergic to cilantro Beautiful new theory of causal selection from @tadegquillien.bsky.social that explains why we sometimes select two causes

Friendly reminder that ordinal values admit an ordering, but no notion of distance. Without a notion of distance even the concept of linear models is ill-defined. Please do not use ordinary least squares to analyze ordinal data. For gratuitous discussion see betanalpha.github.io/assets/chapt....

The Causality in Cognition Lab -- a supportive, bluesky-colored team -- is looking for a predoc to join us! Here are infos about the lab (cicl.stanford.edu) and the position (careersearch.stanford.edu/jobs/iriss-p...). The application deadline is May 1st. Please share, thank you 🙏

it’s hard to overstate how important this is for quantitative research (especially psychology/neuroscience)- computing individual-level stats independently often robs you of hard earned statistical power. highly recommended reading *both* of these wonderful blog posts!

Metacognition ppl, check out this upgraded hmetad package for estimating metacognitive metrics (e.g., M-ratio)! ☑️More efficient ☑️Easier to implement ☑️Comprehensive documentation ☑️New non-confounded measure of metacognitive bias (meta-delta) I’ve just applied this model to my data - working nicely!

I'm looking for a post-doc to help organize Bayesian Data Analysis course avehtari.github.io/BDA_course_A... (200 students) and to do research on Bayesian workflow users.aalto.fi/~ave/publica... at Aalto www.aalto.fi/en, Finland. Background in Bayes needed. Up to five year contract possible.

Out now in Cognitive Psychology, paper spearheaded by @davidyoung-psych.bsky.social showing that questions like "Does a torch cost more or less than a laptop?" can generate mutual anchoring effects: www.sciencedirect.com/science/arti...

If you use GitHub (especially if you pay for it!!) consider doing this *immediately* Settings -> Privacy -> Disallow GitHub to train their models on your code. GitHub opted *everyone* into training. No matter if you pay for the service (like I do). WTH github.com/settings/cop...

Exciting work by @kevingoneill.github.io to extend / rewrite the HMetad toolbox in R and STAN 🥳 We supercharge meta-d modeling within a bayesian regression framework, wrapped in a user-friendly R package with bespoke plotting tools (+ a new principled measure of metacognitive bias, meta-delta!) 🧠🧪

happy to announce the official release of my first R package on CRAN! 🎉 building on the Hmetad toolbox by @smfleming.bsky.social, the hmetad package allows users to fit the meta-d' model of confidence ratings using a familiar brms/lme4-style formula syntax

I mean, I shouldn't be surprised by this, but it's wild how many academics apparently don't want to do the main things (write papers, teach students) they are paid to do

New with @tobiasegner.bsky.social & @mariamaly.bsky.social! The relationship between external and internal attention is not fixed but varies between competition, concurrence, and cooperation. We shed light on the conditions that allow for each of these relationships to occur🔍 psyarxiv.com/ry94x_v1

Our new paper is out in Cognition! What determines whether confidence follows the classic "folded-X" pattern vs. the "double-increase" pattern? The answer lies in the type of stimulus manipulation. Big thanks to my advisor Doby @dobyrahnev.bsky.social and co-first author @herrickfung.bsky.social !

If the brain doesn’t store memories, where are they? Why do we summon the past into the present? Henri Bergson explored these questions. Doudja Boumaza (Grenoble) is at The Memory Palace today encouraging us all to revisit Bergson’s answers. Enjoy! open.substack.com/pub/thememor...

Very happy to see "Pretending not to know reveals a capacity for model-based self-simulation", a collaboration with @chazfirestone.bsky.social and @ianbphillips.bsky.social, out in Psych. Science! journals.sagepub.com/doi/10.1177... 🧵

Quilicura, Chile, one of the communities I wrote about in EMPIRE OF AI, has launched a brilliant initiative to inspire more responsible AI prompting. Today, don't use AI; ask the townspeople instead: quili.ai. So heartened to see this creative act of resistance.

Cow Tools! We have lived alongside cows for nearly 10,000 years. We breed them and exploit them It is now, only now, that we have discovered THEY CAN USE TOOLS Here I describe our study (paper) www.sciencedirect.com/science/arti... in @currentbiology.bsky.social with @auersperga.bsky.social

Our new paper on different types of underconfidence in relation to anxiety symptoms and gender out now in Psychological Medicine 😊 doi.org/10.1017/S003... with @smfleming.bsky.social

My department, Duke Neurobiology, is searching for a new chair. Ad below. Come work with me, @jmgrohneuro.bsky.social @ennatsew.bsky.social @jorggrandl.bsky.social @jnklab.bsky.social @sbilbo.bsky.social @neurocircuits.bsky.social and many other amazing folks! @dukemedschool.bsky.social

Applications still open until February 4! Important note for US applicants: We do consider applicants with only a bachelor's degree and some research experience! You don't need a masters. #CogSci #PsychSciSky

I am not sorry. This is simply true. Academics should be able to write fluently and express themselves clearly and academics should do their own work. It’s literally our job. It’s what we trained until 22nd grade to do. This is a simple observation that should require no explanation or defense.

Very proud to announce that the final chapter of my thesis is now out in Cell Reports! How do neurophysiological traits that characterize individuals evolve across the lifespan? We combined data from over 1,000 individuals aged 4–89 to answer this question. (1/6) 🧠👶👦👧👱👩‍🦱🧔‍♂️🧓👴 doi.org/10.1016/j.ce...

Our new paper in @natcomms.nature.com introduces improv, a flexible software platform that integrates models with experiments in real-time. Traditional experiments collect all data first, then analyze it later. With improv, models analyze data as it streams in and actively guide what to do next.

super excited to say that the first paper from my PhD has been published in Neuroscience and Biobehavioral Reviews 🧠!! “I could have done otherwise”: the neural bases of counterfactual representations -> doi.org/10.1016/j.ne...

New paper from our lab by Ricardo Morales-Torres (@rmt93.bsky.social) on the visual and semantic properties that shape the vividness of mental representations for events past. psycnet.apa.org/record/2026-... The short answer to the title, "What Makes Memories Vivid?" is ... meaning!

Good news everyone: #Duke Summer Seminars in Neuroscience and Philosophy (SSNAP) are back!! We are now accepting applications for SSNAP 2026, which will take place from May 26 to June 6, 2026. #neuroscience #philosophy #brain Please spread the word! ssnap.submittable.com/submit

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp.... genzplyr is dplyr, but bussin fr fr no cap.

Now I'm also looking for a research software engineer to implement a pile of research results to R packages loo, posterior, bayesplot, projpred, priorsense, brms or/and Python packages ArviZ, Bambi and Kulprit. Apply by email with no specific deadline (see contact info at users.aalto.fi/~ave/)

I am hiring PhD candidates to study the psychology of attention & technology use at @tilburg-university.bsky.social. We're looking for motivated & curious scholars with expertise in cognitive psychology and statistics, and offer a friendly work environment with great terms & benefits. tiu.nu/22989

one of the best parts about working in the MetaLab!

Consciousness science as a marketplace of rationalizations my commentary on @smfleming.bsky.social and @matthiasmichel.bsky.social's thought-provoking BBS paper, and more generally about the field. osf.io/preprints/ps...

People who coax chatbots into sensible answers are basically opening and closing the fridge until it contains something you wanna eat, yes, eventually you get hungrier & eat the stuff in there. But what changed was your cognition. The fridge stayed the same. You changed your mind about the contents.

Nothing. I use it for nothing at all because AI is good at zero of the tasks I do regularly Honestly I don't even know what its web address is, is it like a 2000s style ChatGPT.com or something funkier like chat.g.pt

psych departments post a faculty job that has nothing to do with AI challenge

🚨The first paper of my postdoc is out now in @elife.bsky.social! 🚨 We explored the role of attention in planning. Thank you 🙏 to the reviewers for their helpful comments & suggestions. Keep your 👀 peeled for additional analyses and our response. elifesciences.org/reviewed-pre...

🌟 Excited to share that I'm recruiting PhD students in Psychology for my new lab at Rice University this cycle (Signal boost appreciated!) To learn more, check out the Learning & Behavior Change Lab website: www.sinclairlab-rice.com Applications are due Dec 1st: psychology.rice.edu/graduate/pro...

really love this ingenious set of experiments by @jfkominsky.bsky.social & looking forward to reading up on the final one (not to mention that I *highly* recommend seeing him present this for the causal illusion magic)!
