Which Kind of Science Reform What hope is there for science reform, if we can't agree on what to reform? Right now, principles are more important than practices.

How can we reform science? I have some ideas. But I am not sure you’ll like them, because they don’t promise much. elevanth.org/blog/2025/07...

Don't know if you'd consider Andrew Gelman's blog for that list? Maybe not quite the same topic but definitely has some overlap.

Starting tomorrow! Join us for lots of ECR talks about topics from across the field of working memory research!

This Thursday we have our second OPAM online workshop! This one will address the best way to do power calculations to determine how many participants you should run in your next experiment - an increasingly important topic today! The talk will be given by @cjungerius.bsky.social from Cambridge!

Today we call those people Bayesians

Model to Meaning: How to interpret statistical models with marginaleffects for R and Python

📚😅🎉

Yay!! I just submitted the complete manuscript of my upcoming book to the publisher!

Learn to easily and clearly interpret (almost) any stats model w/ R or Python. Simple ideas, consistent workflow, powerful tools, detailed case studies.

We are excited to announce that @cjungerius.bsky.social is joining the team of organizers of WMS 2025! With him joining, the prep for the party is in full throttle!

Exciting updates!
I defended my PhD under @haslagter.bsky.social in January—'Learning What Matters: How to Pay Attention in a Volatile World'—and today, I’m starting as a Research Associate in the @bayslab.org at Cambridge. Looking forward to new challenges ahead!

❗News Alert ❗
Our iBBA (Institute for Brain and Behaviour Amsterdam) is now flying on Bluesky 🦋. If you're passionate about groundbreaking interdisciplinary science focused on understanding the brain and body as a unified system, stay tuned and follow us at bsky.app/profile/ibba...

ReVISit 2.0 (revisit.dev) reached several exciting milestones recently:

📁 You can now define an entire experiment in a single file— from trial data, stimuli (visualizations and interactions, thanks to Vega-Altair), study blocks/sequences and randomization, questionnaires, etc.

I had missed this as well and it really underscores how badly discussions of reform have missed thinking about the models we use and why we use them 🧵

Our PNAS paper "Action similarity warps visual feature space in working memory" is out! www.pnas.org/doi/epub/10..... Thanks to @haslagter.bsky.social and Chris Olivers for guiding me through this project, and thanks to Luigi Falanga and Jannik Jeske for their great lab work. What a team! 🤩🤓

Now that more people are here, I’m signal boosting this great methods primer by my PhD student Chris. Chris is currently in the market for a postdoc, and comes highly recommended! #neuroskyence

A humorous summary of different types of political behavior paper types You should always use this novel (10 year old) model we stole from psych/ CS/ econ/ physics/ /neuroscience You should never use this outdated (15 year old) model we had stolen from from psych/ CS/ econ/ physics/ /neuroscience We randomized stuff – now some things are different and others are not (but we won’t tell you about those) How do we get people to vote? Wait, we didn’t mean vote like THAT! I found a great instrument – now all I need is a research question and a theory My research fund is bigger than yours – a 150 country survey study Survey respondents say the darndest thing Did anybody else notice that things kind of suck right now? A bad thing is associated with another bad thing Getting the band back together: A large-N cross-country validation study of our pet theories

Since this is making the rounds again, an updated version of my "Types of Political Behavior Papers" .

thanks to the iBBA VU our workshop on Info. Theory is in full swing with Dr. Ince (@robince.bsky.social) giving an intro. lecture on info. theory measures. Dr. Canales-Johnson (@canalesjohnson.bsky.social) will follow with a lecture on how to use these measures to study perception and cognition

disclaimer: it has been quite some time since I was 13 so I can't really gauge how difficult this is!
Theory-wise, you can't really do better than 3blue1brown (but same disclaimer as above, might require some tricky maths):

For any modern type of encryption it should be nigh impossible to determine the encryption method from the ciphertext (by design). Classification of e.g., images might be a lot simpler and pretty cool? Keras makes it quite easy in combination with something like www.youtube.com/watch?v=BfCP...

Power Simulation: A primer in 3 languages - Power Simulation in a Mixed Effects design using R

Excited to share my primer on simulation-based power analysis using R, Python, and Julia! Based on @debruine.bsky.social's approach applied to data collected by @kirsten-adam.bsky.social, I hope it's a helpful tool for those starting with simulations. Check it out: cjungerius.github.io/powersim/

The second preprint of my PhD with @haslagter.bsky.social is out! In a followup to our previous work, we test the possible causes for our previous finding that reduced contextual uncertainty affects attentional capture: osf.io/exgvu

Software is both a cause of unreliable research and part of the solution. The bulk of scientific research relies upon specialized software for data managemen... Science as Amateur Software Development (2023 edition)

Science is great but academia not so much. Earlier this week I revised my talk "Science as Amateur Software Development". The unprofessional way that academics curate & process data would benefit from professional habits of software engineers and chefs too 🧪 www.youtube.com/watch?v=8qzV...
