My Shiny app containing 3530 Open Science blog posts discussing the replication crisis is updated - you can now use the SEARCH box. I fixed it as my new PhD Julia wanted to know who had called open scientists 'Methodological Terrorists' :) shiny.ieis.tue.nl/open_science...

Check out this really cool multilab project about the difference in short-term memory between musicians and non-musicians! By @masssimo006.bsky.social, @francescatalamini.bsky.social, and researchers from 33 institutions around the world.

🚨Just published in PSPB: When heavy violent video game players read research that say “these games increase aggression”, they often shift their beliefs in the *opposite* direction. Open Access link: journals.sagepub.com/doi/10.1177/...

#AcademicSky #PsychSciSky I'm always keen to read research where an intervention's success depends on individual differences. Here, science-relevant info on videogame (VG) use & aggression: ✳️ WORKS among low VG users ✳️ FAILS among high users (i.e, no change) ✳️ BACKFIRES among very high users!

Need faire une vidéo sur cet article.

New blog post: Why we should stop using statistical techniques that have not been adequately vetted by experts in psychology daniellakens.blogspot.com/2025/10/why-... where I reflect on how we should check the quality of novel statistical techniques.

Does anyone I know have access to this paper? 🥺 I can't access it from my university. doi.org/10.1016/B978...

🟢 OSF is back online with a refreshed design. We’ve rolled out the updated OSF design, making it faster, easier to navigate, and ready for future improvements. Log in, explore the new experience, and see what’s changed: osf.io.

I unfortunately think demand characteristics are an underappreciated cause of a lot of effects in the lit

New code review response just dropped:

Anyone familiar with robust regression for heavy-tailed residuals? Seems there are many alternatives. The only method I've learned is Bayesian regression with regularizing priors (from @rmcelreath.bsky.social book) and for the moment I want a frequentist alternative (sorry Bayesians) #stats #rstats

New study on #BlueSky for #SciComm. “Bluesky posts demonstrate substantially higher levels of interaction (likes, reposts, replies, and quotes) and greater textual originality than previously reported for X, suggesting both stronger interactive and more interpretive engagement.” 🦋🦫🌱🐋🧪 #philsci

10 years ago?! Holy smokes.

It’s fascinating to argue that LLMs mimic humans when they’re producing effects that aren’t replicated in humans.

So, as evidence of "mimicry", we have the LLM exhibiting effect sizes in the 90th-98th percentile of effects seen in studies of human beings in a paradigm where humans do not replicably show the effect. Not very compelling IMO. mmmdata.io/posts/2025/0...

This has now been published in PNAS! www.pnas.org/doi/10.1073/... The original authors also posted a reply: www.pnas.org/doi/10.1073/... Quick thread on some additional thoughts and then I'm probably done talking about this one 🧵

Why LLMs are not a substitute for humans in research on human behavior: Human participants were responsive to semantic nuances that LLMs didn't pick up. Example: Cut their beard to shame someone vs cut their beard to shave someone. #Econsky

If you are preparing your bachelor statistics course and would like to add optional material for students to better understand statistics on a conceptual level (see topics in the screenshot) my free textbook provides a state of the art overview. lakens.github.io/statistical_...

Been working on a tutorial on synthetic data for open science for @lmu-osc.bsky.social A draft version is now up: lmu-osc.github.io/synthetic-da... It covers model building, evaluating synthetic data utility with density ratio estimation, and disclosure risk. Feedback is very welcome!

New paper by Mark Rubin confirms that my conceptual approach to justify the practice of preregistration is coherent, and a solid and strong logic that provides a basis for preregistrstion in science: link.springer.com/article/10.1...

Some of you noted you could not access our new preprint criticizing the idea of Type S and M errors. The wonderful PsyArXiv moderators have just approved it, so if you didn't read it before, take a look: osf.io/preprints/ps...

Probably no-one except me uses my R tutorials in their teaching, but if you do, I'm re-writing them over the next 6-9 months. My goal is to streamline them based on 5 years of using them in class, but if you have (polite) requests/suggestsions let me have them. www.discovr.rocks/discovr/

New 📰 Demand characteristics are a fundamental methodological concern in research with humans Yet little is known about the magnitude and consistency of these effects In a new paper, I, M. Wyatt, and @mcxfrank.bsky.social take stock of what we’ve learned via meta-analysis doi.org/10.1525/coll...

This is in my view the most relevant paper about demand effects, and one of the most important papers to read for anyone doing social science research! I highly recommend it!

We will soon put up a preprint where we criticize the concepts of Type S and M errors. They are not useful when designing and interpreting studies. Better solutions exist for the problems they are intended to solve. If you like these concepts, which points would we need to address to convince you?

The experience of getting reviewed by substantive researchers and methods researchers is so different. With methods people, you can make the case for or against something using only... *logic*. This is so refreshing.

🧵1/ 🚨 New article out! How robust is the psychology of social class? Together with Nicolas Sommet and ‪@frederiqueautin.bsky.social‬, we conducted large-scale replications of 35 hypotheses across four countries. Published in Nature Human Behaviour: www.nature.com/articles/s41...

At this point, I might as well -- Here's an infographic showing different ways to include age as a predictor. The top shows two extremes, just as a plain old numerical predictor (imposes linear trajectory) vs. categorical predictor (imposes nothing whatsoever). And then three solutions in between!

🚨New paper in @cp-trendscognsci.bsky.social 🚨 Why do some ideas spread widely, while others fail to catch on? We review the “psychology of virality,” or the psychological & structural factors that shape information spread online and offline: authors.elsevier.com/c/1lRke4sIRv...

Missing data and confusing errors are common frustrations in R. Nick Tierney faced such challenges but instead of giving up, he developed {naniar} for exploring & visualizing missing data, honed his skills in testing R code & packages. His experience might inspire you! Tune in: buff.ly/6itXLHs
