AI is destroying the sources of knowledge that it's trained on, because real human experts no longer have the incentive to donate their time on platforms like Stack Overflow.

inspired by @russpoldrack.org's AI policy for his lab, last night I drafted up this AI policy and came up with an initial set of use case suggestions for my lab

I need someone to talk me out of rebranding my lab to the Social Assessments and Measures lab

I feel like "The conclusions of this paper are fully in line with the corresponding author's whole schtick so they really want them to be true" should count as a conflict of interest #phdsky

The funneling of public funds into for-profit companies has been devastating public infrastructure for decades. Now it's come for the NSF.

New team science initiative just dropped! manyscale.org We're looking for collaborators to lead repositories of self-report measures in their own psychology subfields.

#psych content journals need sections for pure methods papers. Methods papers are put in methods journals read by methods people. But non-methods folk don't read those journals, so they miss the methodological insights/updates. Where are the content journals that eagerly publish methods papers?

Within the next year, we'll be looking for folks to help expand this website into "ManyScale". We want to help you use this code to make your own repository for your subfield. SelfScale, EmotoScale, PoliticoScale, etc. If that sounds exciting to you, please reach out!

Inspired by this wonderful repository, I've begun the process of making my own repository of published self/other-report measures in aggression science. It's incomplete but I hope it's a start to something useful to those who study human harm-doing. davidchester.weebly.com/aggression-s...

Social/Personality Psych people: what are some of your favourite research software products/papers that have come out in the last ~5 years?

Looks like this will be a super valuable resource for folks interested in relationship science across different disciplines. Very cool!

Every scholarly area needs a measure repository like this.

We made an open repository of close relationships measures. Our goal is to catalogue all of the published self-report measures in relationship science. You can help us expand the database by suggesting measures you tend to use in your research, or by uploading your own measures! relascale.com

I'm working on a review of close relationships measures. Going back and reading the original papers in which our classic scales were validated has been an eye-opening experience. E.g., Spanier's (1976) dyadic adjustment paper opens by arguing that we shouldn't use marital adjustment as a construct.

Will have more to say about the dySEM paper (w/ @omarjcamanto.bsky.social )/JOSS another time, but for, now, just struck--similar to doing my first Registered Report--in terms of how much I feel like this approach (not without tradeoffs) is a big improvement in terms of scientific value-allignment

It’s amazing how many topics and research areas largely just boil down to attitude valence.

Kind of a wild finding, that in hindsight nonetheless makes sense. How many other “multidimensional” constructs boil done to a positive versus a negative evaluation?

I was STUNNED that this model ended up being the winner. No Big 5, or Big 3, or Big Anything. Relationships measures capture positivity, layered on top of item-specific content. That's it. It feels like we need to start developing new measures from square one.

New paper, out this week in PLOS One, suggests that most close relationship self-report measures are primarily capturing relationship quality 🧵 journals.plos.org/plosone/arti...

Exciting! #cdnpoli

Given how machine learning practices have evolved in the last decade, I was very curious if these findings would hold up. Many thanks to Florian for his nuanced and thorough review. Romantic desire: not predictable in 2017, not predictable in 2026.

Our institute is hiring 1. an assistant professor (with TT) for Social Psychology (focus: environmental psychology) ohws.prospective.ch/public/v1/jo... 2. an assistant lecturer (with TT) for Experimental Personality Psychology ohws.prospective.ch/public/v1/jo...

Aside from the bonkers horse analogy, this argument belies an unfortunately common perspective that the reason why teachers and professors assign homework is because it somehow benefits us for that work to get done.

We're all very excited around here to read @pauleastwick.bsky.social's new book!

New post! "Valuing the Process vs. the Product in Research," in which I try to describe some of the tensions around using GenAI/LLMs in scientific research, and why it can be so difficult to have productive conversations on the topic. getsyeducated.substack.com/p/valuing-th...

This isn't scholarship—it's mimicry. Not science—a performance. When the "writer" understands syntactic patterns but not the underlying meaning, the product loses its soul. Sure, it's in APA format. But under the hood? Slop. Scientific writing isn't just ritual. It's where true creativity resides.

Next semester, I'm moving to an in-class only evaluation format. No more term papers, no more take-home assignments. All assignments completed entirely in a computer lab with TAs present. I'm convinced it's the only way to ensure the integrity of the evaluations.

We extended the deadline of our machine learning competition by a few weeks until mid March! Still time to participate. We currently have 233 participants with 111 total submissions (some of them will be test submissions etc).

Lessons from other eroded democracies show there’re multiple ways to destroy the free press.Yes, you can arrest/intimidate journalists like last week.You can also buy news organizations, destroy their credibility and gut their newsrooms. You can sue frivolously until newsrooms can’t afford to fight.

Some thoughts: 1. The deadline for nominating a person or group for the Nobel Peace Prize is Feb. 1. 2. History professors are qualified nominators. 3. The people of Minnesota have been awe-inspiringly peaceful in the face of state violence. 4. He would be so mad.

Jill made history as the first Black, queer MPP in Ontario, and she’s fought relentlessly for affordable housing, health care, the arts, and gender & racial justice. She is a principled, courageous leader who knows how move a room — and a movement. I'm delighted to have her support.

We have a new paper in Science today on how malicious AI swarms can threaten democracy. AI systems can already coordinate autonomously, infiltrate communities, and fabricate social consensus. www.science.org/doi/10.1126/... Led by @kunstjonas.bsky.social & @daniel-thilo.bsky.social!

Great piece on prioritizing quality over quantity in scientific publication. For those of us with labs, this necessarily involves shrinking our group size. After I got tenure I started to downsize my lab and have not regretted it one iota. More time for each student & more time to think & write.

If you're a progressive in Canada, you should know that the NDP leadership race is currently ongoing, and January 28 is the deadline to register with the NDP to be able to vote on the next party leader.

My absolute favorite aspect of this premise is the part where the general public is willing to read a dissertation in exchange for money.
