Pilgrimage. #rstats

Anthropic just released Claude Science. www.anthropic.com/news/claude-...

I challenge anyone go try and reproduce some random papers, even those based on open free public datasets, but without the code and/or a detailed description of how the data was obtained and processed, and not become militant about the necessity of code and complete data sharing at a minimum.

Why is that bad though?

for undergrads getting their degrees this Fall: if u're computationally savvy & wants to get into cog neuro -- instead of taking up lab manager / RA positions, why not come to Korea & get a master's degree instead? it will be all paid for w/ stipend, of coz. why would u pay for a master's degree??

Oh wow Scott Alexander has a really terrible piece one whole body scans. I am surprised. www.astralcodexten.com/p/should-peo... 1. Scott's math rests on a bad assumption: that "the cost of treating the treatable cancers is zero," because doctors can leave the indolent ones alone.

TODAY: Listening to Richard McElreath "A Guerrilla Approach to Scientific Workflow" https://peercommunityin.org/pci-webinar-series/ Here's a dispiriting chart he shared from Serra-Garcia & Gneezy 2021 https://doi.org/10.1126/sciadv.abd1705 "Nonreplicable […] [Original post on mastodon.online]

New paper! w/ @cocoscilab.bsky.social🧵Can large language models reason flexibly, or have they learned what reasoning looks like? We introduce a new paradigm to test this question—the riddle riddle—and find that humans and LLMs show opposite patterns of performance. 📜

New preprint! AI agents have shown impressive scientific automation capabilities. Can we apply them to psychology research, *including* human data collection? We introduce auto-psych, a framework that proposes cognitive models and uses them to design and run human experiments. 1/

Our metacheck package now has an online manual! In 29 short chapters we explain how to set up metacheck (running all modules 100% locally if you want), and explain the 18 available modules. www.scienceverse.org/metacheck_bo... We are still in beta, and would love to get feedback!

posterior R package has now JOSS paper you can cite, too joss.theoj.org/papers/10.21... with @paulbuerkner.com , Jonah Gabry, @mjskay.com

Yes when I was first doing work on the replication crisis around 2012-ish this was one of the most striking things to discover by learning the history ... it was déjà vu all over again

What is interesting about psychology is that they did the whole replication crisis one time before in the 1970s. It is so similar to the 2010 one, you would not be able to tell if a paper on the replication crisis was published in 1972 or 2012. See rips-irsp.com/articles/10....

I was very fortunate to work as a visiting scholar at the Bennett Institute at University of Oxford for 6 months. Below I reflect on that experience, what we achieved, and what's yet to come! It's a privilege to get to continue to work with these great folk. www.bennett.ox.ac.uk/blog/2026/06...

There’s been a lot of buzz around the Borjas/Breznau (2026) paper (www.science.org/doi/10.1126/...) and potential ideological bias in research. We took a closer look at the data. Could there be a "bias in bias research"? Here is what we found: www.econstor.eu/bitstream/10...

People always say "tell a story" but then don't explain how to do so! How is that helping? If we knew how to tell a story we wouldn't need the advice in the first place. 1/

New post! "Making Sense of Replications (and Some Nonsense about the Replication Crisis)," in which I suggest a journal club reading list of new papers on replication, and push back on claims that the replication crisis is fake. getsyeducated.substack.com/p/making-sen...

New interactive blog! "Why Adjusted Regression Coefficients Are Less Descriptive Than They Look" rpsychologist.com/descriptive-...

HBS' latest filing in the Gino lawsuit contains a few new details: 1. A committee of 26 professors, admins, and fellows reviewed the allegations, and *unanimously concluded* that there was *clear and convincing evidence* of research misconduct.

Musk says not a single person has died due to him axing USAID. Sadly, part of my job involves tracking aid spending. So here’s a thread with just some of the people who lost their lives because of USAID cuts

A new paper by @dominiquemakowski.bsky.social, @mattansb.msbstats.info, me and colleagues just out! We show how to choose informative priors in Bayesian regression models using a systematic simulation study and a practical step-by-step tutorial in #Rstats and #Stan! doi.org/10.3389/fpsy... >

I have been doing econometrics and data science consulting in academia and the private sector for a decade, and for the first time in a while I am open to new clients. If you are looking for someone to help you with data stuff, drop me a line! nickchk.com/consulting.h...

Have you used Bayes factor to test point-null hypotheses in Hierarchical models and wondered: 1. Bridge sampling (BS) or Savage-Dickey density ratio (SDDR)? 2. If SDDR, which density estimation method? 3. How many MCMC samples? 4. What's the cost-benefit trade-off? This may be of interest to you.

If p < 0.05, you "reject the null." That's what many stats courses teach you to do. This week's Experimentology chapter argues that this binary, dichotomous frame can sometimes be useful but is the wrong default for psych experiments — there is a broader toolkit available! 🧵 experimentology.io

People have century-scale ambitions with pronatalist programs, but results are limited to fragments of a decade. Here, Romania banned abortion in the 1960s, resulting in untold human suffering and death; and Russia paid out many billions in child subsidies after 2007. And yet history moves on.

A proposed US Office of Management and Budget (OMB) rule would give political appointees authority to terminate active grants, override peer review & restrict international collaboration, publications, & conference attendance. Submit a comment before July 13: www.psychologicalscience.org/act-now

Growing up in rural Texas as a low socioeconomic status ranch girl, I was accepted to my #1 university choice - Carnegie Mellon - and when I saw the "Total costs" line, I immediately knew I couldn't go.

Somehow I didn't expect these two interests of mine to collide.

⚡ Metaventory: building better science ⚡ Had many discussions about the need for mapping out all that's meta-science: people, tools, events, jobs, simulations, etc. in one place. Metaventory aims to help connect those interested in meta-science & improving science. metaventory.vercel.app

Russell Vought's one rule to rule them all isn't in effect yet. Write to Congress AND comment on the proposed rule by 13 July. WE CAN STOP IT. elizabethginexi.substack.com/p/what-we-ne...

"A higher capital stock... encourages more automation and thus more repression....we show that, starting in a democracy, capital accumulation and thus greater automation encourages the capitalists to support a coup against democracy and set up a repressive system." 😯😯😯

i think there are a lot of people who would find it very hard to believe that the field of economics could produce this paper. and yet! Acemoglu is like the mainstreamest and most successful economist working today. some priors could use an update. www.nber.org/papers/w35336

found a guy on the local LLM subreddit who tests open source models running on his computer by asking the program to animate a doner kebab on a spit

I too am "in the weights" and honestly quite accurate too.

More evidence, from a large-scale study in China, that using AI hurts learning if it undermines mental effort. When homework time drops due to AI use, so do test scores. Across studies, there is a clear theme: AI tutoring in support of classes is good, using AI to "help" with homework is bad.

New paper out now! We (w/ @rmcelreath.bsky.social and @gregork.bsky.social) start from the observation that among adolescents in Leipzig, the gender gap in life satisfaction has doubled over time and ask: why?> link.springer.com/article/10.1...

This paper finds that economists whose job market papers report (marginally) statistically significant results are more likely to secure academic jobs. Hiring committees prefer statistical significance; this creates incentives for researchers to p-hack.

I built a website that tracks open source tools that provide automated checks for scientific manuscripts: lakens.github.io/automated_re... It provides a summary through RSS feed that you can subscribe to. It tracks 13 repositories - if you want your repo to be included, let me know!

I have updated the layout (but the old one is a slider away), and added projects. If you are building open source tools that assist scientists in adopting best practices, let me know and I will add you.

BREAKING The R Core Team just awarded the prestigious Rousseuw Prize in statistics, stats equivalent of Nobel Prize 🏆 🏆🏆🏆 #rstats A team effort over many years suitably recognized

Our new paper, Rethinking Type S and M Errors, is out. We argue that these statistics do not facilitate the proper design of studies or the meaningful interpretation of results.  doi.org/10.1177/2515...

🚨University of Pennsylvania will be re-instating the GRE as a requirement for Psychology PhD admissions for the coming cycle 🚨

At the end of the term I asked my college creative wriing students to submit anonymous thoughts on AI. No real surprises: Mood ranges from resignation to despair, capitulation from embittered erosion of standards to total, feelings of betrayal from deep to furious. 1/

Oh boy. Oh dear.
