Mit diesen vier Methoden schüchtert die AfD Lehrkräfte ein Wir haben in den vergangenen Monaten unzählige vermeintliche Einzelfälle analysiert. Nun ist klar: Der Angriff der Rechtsextremen auf das Schulsystem folgt einem klaren Muster.

Konservative 🤝Rechtsextreme = politischer Selbstmord?

In vielen EU-Ländern versuchen konservative Parteien durch Kooperationen, rechtsextreme Parteien zu „zähmen“. Die CDU-nahe Konrad-Adenauer-Stiftung hat untersucht, was das für Konsequenzen hat. Spoiler: Es funktioniert nicht. 1/6🧵

That's interesting - thanks for comparing the methods and for letting me know!

Analytical solutions are of course more elegant than numerical integration.

For all who use Bayesian hierarchical models, have a look at our new preprint, out now together with @linushof.bsky.social @nunobusch.bsky.social and @thorstenpachur.bsky.social

Still, it is worthwile to have a paper elaborating on this in detail!

TreeBUGS: An R package for hierarchical multinomial-processing-tree modeling - Behavior Research Methods Multinomial processing tree (MPT) models are a class of measurement models that account for categorical data by assuming a finite number of underlying cognitive processes. Traditionally, data are aggr...

Just a remark regarding "The same incorrect computation appears in implementations of latent-trait multinomial processing tree models":

The issue has been mentioned in the literature (shorturl.at/Ajx0W), and the R package TreeBUGS has the function probitInverse as a solution (shorturl.at/mRp1S).

Looks and reads great, I especially like the concise figure!

This is an important issue which is often overlooked, so the contribution will be useful for many modelers. 👍

Grand Designs: the loss of American freedom Exactly seven months into Trump's second term, we have reached 1000 authoritarian actions. Here I lay out the enormity of what has happened.

1/3 I think the premise is worth some attention: why is there a (frequently wrong) expectation that science is precise? I am often confused even by textbooks for university student audiences. Confused about how frequently findings and expert judgements are portrayed as certain and final.

It would be good to learn already in school that uncertainty is a fundamental aspect of science.

I guess people generally dislike being in a cognitive state of uncertainty. But I vaguely remember some studies showing that scientists are better at coping with it.

Expert Judgment and Communication of Uncertainty Knowledge built through the scientific study of climate is essential for informed decision-making. In the presence of irreducible uncertainty, the results of climate science must be gathered and synth...

"Science is expected to be precise, and admissions of uncertainty (especially large levels) can be perceived as scientific failures, rather than natural limitations of knowledge of a topic." 😕

Just submitted a minor bugfix of RRreg to CRAN:
github.com/danheck/RRre...

The R package focuses on analyzing univariate & multivariate data collected with the Randomized Response Technique (RRT), which protects anonymity in surveys by randomly scrambling responses.

I also added a new logo 🚀

What an incredible resource from the indefatigable @chrischirp.bsky.social . No one can say we didn't know -- it's all happening in broad daylight.

Ein ganz ganz wichtiger Text in diesen Zeiten. "Die vorliegende Kampagne gegen eine deutsche Top-Juristin ist nichts anderes als ein weiterer Versuch der Trumpisierung deutscher Politik. [...] es liegt kurzum an wirklich allen Demokraten, dies nicht zuzulassen." 👊

of course, we also need a new badge!

The effort by the authors is laudable and may be useful in itself.

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

AI, peer review and the human activity of science When researchers cede their scientific judgement to machines, we lose something important.

A few months ago, Nature published how-to guide for using ChatGPT to write your peer reviews in 30 minutes.

This is, of course, a horrible idea. Here’s my response with @jbakcoleman.bsky.social .

Thanks for this overview!

A related issue regarding the mixed results is the ambiguity of fluency theories regarding the required boundary conditions:

If the manipulation is too salient, it is assumed that people can discount the effect; but if it is too weak, there might be no effect at all. 😕

Research on processing fluency used to be very popular with publications in Psychological Science, PNAS, etc. Now there are several prominent failed replications of fluency effects. A newest one: bsky.app/profile/dani... >
