Looking for books to get for #climate curious friends & family this Christmas🎄?

Here are 6 of my favourites reads this year.

First up, Yale University historian Sunil Amrith's relentlessly edifying 'The Burning Earth'. A staggeringly comprehensive account of how we got to where we are! 🧵

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

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps:

I find this really interesting. Like many, I shared this paper because it appealed to an intuitive thinking: here's another critical look that debunks a psychology classic.

It also says something about our field that some ideas can be robust even if they initially just come from a story basically.

Byrd, N. (2025, July). Map My Words—Using Waitlist Controlled Trials To Test Whether Argument Mapping Improves Individuals’ Persuasive Writing or Critical Thinking. Experimental Argument Analysis, University of East Anglia. https://www.researchgate.net/publication/390977878 Abstract. Argument mapping is the practice of diagraming the logical relationships between each proposition in an argument, including objections and counter-objections. Some studies find that courses that teach students how to map arguments exhibit better critical thinking and persuasive writing than students in other courses. These promising results are sometimes from surveyors of argument mapping goods and services, and they garner plenty of attention in fields that champion careful thinking and communication. However, the total evidence is mixed, null results are often never published, and many promising studies have not controlled for known confounds. Two waitlist control trials (N = 83) attempted to address these issues; they detected no benefits of argument map training within or between groups (p > 0.13). Rather, variance in outcomes was explained by enrollment in the instructor’s other courses, prior academic achievement, and — most robustly — engagement in flipped classroom activities. These findings raise questions about whether benefits previously attributed to argument mapping in less controlled studies were caused by other factors that were already known to produce such benefits. Implications for pedagogy, course assessment, and the science of learning are discussed.

🧠🏔️ Below I'll share mine and others' presentations from the Society for Judgment and Decision Making conference in #Denver.

Did you attend a session I missed?

Long live #openAccess conferencing.

My god, if that's the first place you'd put people, what's the second?

knowing many directly affected, I personally asked some senior male colleagues to speak out about this during my earlier years as a professor, as i felt too vulnerable due to my stage of career.. it was shocking how much this was 'common knowledge' among women and how few male colleagues knew 😔

Computational Turing Test Reveals Systematic Differences Between Human and AI Language Large language models (LLMs) are increasingly used in the social sciences to simulate human behavior, based on the assumption that they can generate realistic, human-like text. Yet this assumption rem...

LLMs are now widely used in social science as stand-ins for humans—assuming they can produce realistic, human-like text

But... can they? We don’t actually know.

In our new study, we develop a Computational Turing Test.

And our findings are striking:
LLMs may be far less human-like than we think.🧵

This will either increase my course evaluations or get me sent to the dean. Let's see!

This is all p misleading IMO. I just saw this link so haven't read it yet (but will, though I also think lots of the retweets of this haven't read it as well, given its provenance).

Ok, just wow. If the content of this article is right, this is depressing. We're slowly reaching the point where ~100% of what I was taught in Social Psych was either innocently wrong or plainly frauded

Interested in doing a PhD at the intersection of human and machine cognition? ✨ I'm recruiting students for Fall 2026! ✨

Topics of interest include pragmatics, metacognition, reasoning, & interpretability (in humans and AI).

What's the take home message?

If you're submitting AI slop you're a loser. You're just making these great free services harder to run, and making it more difficult to separate signal (science) from noise (your crappy AI shit.)

On the other hand, this is great for my cognitive dissonance when I ultimately get rejected for my Vidi project.

Me to my head of department: "If it weren't for all these pesky US researchers I would've gotten away with it..."

At this point, the first thing everybody is doing when reviewing anything is to scan for AI use.
So in that regard, this tech is creating jobs.

I've finally got around to curating a selection of films about the #climate crisis 🎥

There's lot of mediocre climate films out there, but for me these stand out head & shoulders above the rest 🎞️

They make excellent resources for classrooms, lecture halls, or community cinema's 🎬

1. Paid publishers who sell you stuff you work for free
2. GenAI that sells you stuff based on stolen work

Universities be like: I would like to pay to keep these two in business.

If one is to trust polls, because of a large number of still undecided voters, the Dutch election is shaping up to be, unpredictable.
