"Silicon samples" are becoming more and more common in research and polling.
One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.
The updated version of this preprint is now online!

@lukasgunschera.com joined The Naked Scientists to unpack whether social media is truly “addictive” as a US jury finds Meta & YouTube partly responsible for harm.
Key point: problematic use is real, but evidence gaps remain.

UKgov publishes new screen time guidance for under 5s
👨🍼 <2s: Avoid screens except shared activities
👶 2-5s: Try for less than 1hr a day
📱 Choose safe, slow-paced content
🧑🧒🧒 Lead by example
🛌 Have screen-free areas/times
Glad to have contributed. Parent guidance and research report linked below.
There are other reasons for the UK government not to award or continue Palantir contracts but this statement of intent by its CEO must surely be decisive?
"I don't get it. Why are they confessing?"
"They're not confessing. They're bragging"
Slides of the talk with samples and the task
Slide with the results across the 4 samples
Slide with discussions about the brain gut results
Slide with results about pre and post-stimulus oscillations
So many inspiring talks (here by @saramehrhof.bsky.social, Sameer Alladin, @studenova.bsky.social) and discussions on the first day of the #MindBrainBody Symposium 2026!

🎉 Congratulations to @georgiaturner.bsky.social for passing her PhD with flying colours today! A meticulous and truly interdisciplinary piece of work.
Thank you also to @lorenzspreen.eurosky.social and Paul Fletcher for acting as examiners 🙌

What if the relationship between smartphone use and mental health depends not just on specific harmful or beneficial activities, but also on how users transition between activities?

Delighted to share that our paper "Associations between early-life mental health and abnormal sleep duration in midlife: findings from a prospective cohort study in Great Britain" is now published in @springernature.com European Journal of Epidemiology! rdcu.be/e5rAK 👇
We are recruiting! Postdoctoral research fellow at www.sdn-lab.org, studying the computational & neural basis of social decision-making. Birmingham is a fantastic & affordable place to live, with one of the youngest populations in Europe & over 600 parks. Please share!

A new study from Anthropic finds that gains in coding efficiency when relying on AI assistance did did not meet statistical significance; AI use noticeably degraded programmers’ understanding of what they were doing. Incredible.

Ever wonder what proportion of high profile social media research is tied to the tech industry?
New from me, @cailinmeister.bsky.social, @jevinwest.bsky.social and @carlbergstrom.com.
Thread tomorrow.

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!
course schedule as a table. Available at the link in the post.
I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.
I will record lectures & all will be found at this link: github.com/rmcelreath/s...
In my paper Sample Size Justification I discuss 6 approaches to justifying sample sizes. The focus of the paper is to teach people the tools they need to be honest when they explain where their sample size comes from. I know, so radical ;) online.ucpress.edu/collabra/art...
I’m glad to see on platform ranking algorithm work done without platform scientists in the mix.
I think it’s quite telling that, by the only means we have to verify Metas election collaborations results… we can’t confirm their claims of little to no effect.

Researchers propose new constructs and measures faster than anyone can track. We (@anniria.bsky.social @ruben.the100.ci) built a search engine to check what already exists and help identify redundancies; indexing 74,000 scales from ~31,500 instruments in APA PsycTests. 🧵1/3
Is Santa Real? Many users feel they're getting presents from him. Scientists say it's time to consider whether they're onto something.
It’s really hard to defend industry academic collaborations with meta as earnest, if they’re internally burying evidence of harm.

Perfect, this is what I was looking for - thank you :)
Thanks for your help!
This might work - thanks for sending!
Thank you! I should have mentioned that I have drafted this in Avicenna and m-Path already. Although Avicennda does allow for this, it also requires creating separate follow-up questionnaires for each time interval. At 30min intervals this results in 96 versions, which I am trying to avoid
cc @eikofried.bsky.social @ruben.the100.ci who might know?
I'm looking for EMA software that can do relative scheduling: participants report a time in their first daily questionnaire (e.g. "woke up at 7am"), then follow-ups trigger x hours after that reported time. I would greatly appreciate any recommendations!
It’s astonishing how many researchers seem to believe that a cluster analysis is such a sensible analysis that it needn’t even be justified through a coherent research question. Just cluster analysis go brrrrr
Exciting PhD opportunity with @matti.vuorre.com! ⬇️
