What is Educational Psychology? Proudly presented by APA Division 15. Narration by Dr. Jeff Greene.

🗣️ Let me speak to my people for a second: Hey Learning Scientists and Educational Psychologists: The world has questions you can answer: Should we use GenAI to learn? Is social media destroying our attention and thus, education? How do we support teachers who have the same questions? Get involved! 💪

The formula for an expectation, but instead of a random variable, it is a picture of the Monty Python troop from The Nobody expects the Spanish inquisition sketch.

A cartoon child labeled “bayesians“ staring longingly at some bread labeled “half Cauchy priors”

A picture of the former pope labeled f of x looking at a exact replica statue of himself labeled f-hat of X

A woman on a fishing boat labeled “researchers” tosses an alarmed looking lobster labeled “data greater than two standard deviations from the mean” off of a boat

Some of my best work for your review 🙇🏻‍♀️

This week in the Lancet: “Plastics cause disease and death from infancy to old age and are responsible for health-related economic losses exceeding $1.5 trillion annually.”

🧪 A quick break down and call to action in this thread.

Bertha Benz c. 1870, hair in ringlets, lace fichu. B&W oval photo

Bertha Benz drove 66 miles in 1st long distance car journey #OTD 5 Aug 1888, driving w' 2 sons from Mannheim to Pforzheim. Had tired of husband tinkering with his prototype so took it on the road without him, fixed technical issues en route & raised lots of publicity en.wikipedia.org/wiki/Bertha_...

After I complained bitterly about gerrymandering in the US, someone shared this photo with me “you’ll hate this chocolate”.

52% cacao 100% unfair 🤣🤣🤣

🧠 Why trust some experts but ignore others? Worsnip et al. show how bias, ego & ideology shape our choices. TL;DR: Trust experts more when topics are complex. 🤔🔍

Vladimir Putin killed this little girl

Playing (With) Video Games According to a famous anecdote about the origins of Super Mario 64—that is, about the origins of 3D platforming—before designing any levels, enemies, or objectives, the game's designers began with mov...

I started a newsletter! It's called "Critical Theorycraft," and I'll be writing broadly about games, literature, and media every two weeks or so. The first post is up today, and it's about how cool it was to play Nintendo 64 in a hotel room. Toss me your email and you shall be rewarded with posts!

Brain Surfaces of 70 primate species

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

Basic Income Pilot Project / Study results What does a universal basic income really achieve? Find the results of the first long-term German study here.

🇩🇪 3-year universal basic income (UBI) study, in which n=120 received UBI, n=1500 did not. Website is pretty neat, check it out for core findings.

There is also www.berlin.de/labo/mobilit... which is a bit cheaper and has English translations. It does not matter if the car is registered in Berlin.

I'm digging the #GitHub style post activity, but for my #BlueSky posts. Thanks @blueskymeter.com! :)

How to create your own RAG applications in R See how to query documents using natural language, LLMs, and R—including dplyr-like filtering on metadata. Plus, learn how to use an LLM to extract structured data for text filtering.

RAG has come to the tidyverse! Check out my step-by-step #InfoWorld tutorial on how to use the {ragnar} and {ellmer) #RStats 📦s to answer natural language questions about a document or Web page.

WeTransfer TOS says they can use all your uploaded content for genAI

Bye forever, WeTransfer.

Check out these collections of books (there are also books for applying to PhD and PhD students!) I contributed to the latter 2 & many other (much more knowledgeable) people did. Besides, all proceeds go to support Ukraine!

Are a few people ruining the internet for the rest of us? Why does the online world seem so toxic compared with normal life? Our research shows that a small number of divisive accounts could be responsible – and offers a way out

Only a small % of people engage in toxic activity online, but they’re responsible for a disproportionate share of hostile or misleading content on nearly every platform

Because super-users are so active, they dominate our collective impression of the internet www.theguardian.com/books/2025/j...

A lot of discussions about open science in psychology happened on blogs. I have been archiving them and will make their content available. I remember 37 blogs (with 2827 posts!) but which blogs did I forget, and are not on my list? Please share and reply with any that are missing!

A diver surrounded by plastic garbage.

This changes the scale of the #microplastics crisis.
We’ve known about the 3 million tonnes (MT) of floating plastic in our oceans for years. But that’s just the surface. In the North Atlantic alone, 27 MT (9x!) of nanoplastics are suspended in the water column. 🧪

Can protests move bystanders, people who observe protests without being part of the march?

We conducted a 3-wave field experiment during real Fridays for Future (FFF) protests in Berlin.

Here's what we found 🧵👇

Did a Q&A for @cellpress.bsky.social about trust in (climate) science, political polarization, and what evidence-based strategies scientists can take amidst political attacks on climate and sustainability science! www.sciencedirect.com/science/arti...

I am privileged to announce the publication of the Anti-Autocracy Handbook: sks.to/autocracy 1/12

Horrible day in Kyiv today... Russians deliberately targeted a lot of apartment blocks, causing many fires, destruction, and casualties.
Please continue supporting Ukraine, and donate to the air defense to prevent such tragedies e.g u24.gov.ua/sky-sentinel

Screenshot of the title page of an article published in British Journal of Educational Technology titled "Mapping the self in self-regulation using complex dynamic systems approach"

I appreciate researchers' desire for "person-centered" approaches, but latent cluster analyses are just as "variable-centered" as regression. Complex dynamic systems approaches are actually "person-centered". #PsychSciSky #AcademicSky #EduSky
