Simonsohn has now posted a blog response to our recent paper about the poor statistical properties of the P curve. @clintin.bsky.social and I are finishing up a less-technical paper that will serve as a response. But I wanted to address a meta-issue *around* this that may clarify some things. 1/x

New blog post from Data Colada, responding to the recent criticisms on p-curve analysis. It is a *very* good response. As in, it addresses exactly the points I would have expected in a reply, and it explains why I will still teach p-curve analysis. datacolada.org/129

I'm not making this up. LLMs always will. Says the math.

💖This paper has been ~11 years in the making - and probably my favorite project of all time. Thrilled to see it in @pnas.org! I'm so lucky that Zach decided to do a second PhD and join my lab @psychillinois.bsky.social back in 2014 - a fabulous scientist & human being! www.pnas.org/doi/10.1073/...

Two new preprints on multilevel HMMs! Time series data is now pervasive in psychology and new methods are needed to model the dynamics in such data. Hidden Markov Models (HHMs) are powerful models for dynamics in which a system is switching between a number of discrete states.

Hmm. 🤔 Enrollment in bachelor's degrees in #Physics seems to have fallen off a cliff in German universities since the pandemic. Anybody know if this trend has reproduced itself in your country or in another STEM field? #EduSky #AcademicSky #Science 🧪⚛️ Source: www.dpg-physik.de/veroeffentli...

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)

Why can you breathe Earth’s atmosphere? The answer isn’t that the Amazon rainforest is producing excess oxygen on the surface. (It’s not.) It’s that fossil fuels exist. I didn’t understand this at all before reading @peterbrannen.bsky.social’s new book. heatmap.news/podcast/shif...

Complex behaviour is not limited to animals! Here we map the entire spectrum of waveforms dynamics on a quadriflagellate single cell with 4x 70um (!) #cilia, to a low dimensional behavioural manifold with surprising structure! #protistsonsky All revealed in our new preprint doi.org/10.1101/2025...

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper on that is out today.🧵

The plotannotate package (#RStats) is now on CRAN: cran.r-project.org/package=plot... The package allows users to annotate base R graphics plots with freehand drawing, symbols, and text. This is useful for teaching (e.g., to visually explain certain plot elements) and creating quick sketches.

{truffle} is an R package for teaching users to process data. Semi-realistic psychological datasets with predetermined effects (via `truffles_` functions) are then hidden in common data processing headaches (via `dirt_` functions) for students to clean and analyze. mmmdata.io/posts/2025/0...

OpenAI recently released GPT-5, and its smaller derivatives, GPT-5-mini and GPT-5-nano. On paper, GPT-5-nano is much cheaper than GPT-5-mini: $0.40 per million output tokens for nano vs. $2 per million for mini. But behind the scenes, nano is secretly costing the user almost as much as mini. 🧵

An abbreviation (ABB) in a journal article (JA) or Grant Application (GA) is rarely worth the words it saves. Every ABB requires cognitive resources (CR) and at my age by the time I'm halfway through a JA or GA I no longer have the CR to remember what your ABB stood for.
