yeah, but also "... —or if you need to do it to pay the bills." 🙃

This is the largest cross-linguistic study on SP to date that used computationally selected stimuli and a continuous lexical decision task. The results reveal consistent & robust priming effects across both Latin & non-Latin languages, pointing to a generalizable cognitive mechanism of SP.

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

No link between paracetamol use during pregnancy and autism or ADHD in children In the largest epidemiologic study to date of the risk of giving birth to a child with autism, ADHD or intellectual disability following acetaminophen use during pregnancy, researchers found no associ...

'Tylenol' is known in the civilised world as Paracetamol

2.4 million children born in Sweden between 1995 and 2019. Studied 186,000 children whose mothers were treated with paracetamol during pregnancy.

The net result is the worst of both worlds. Universities invoke the rhetoric of business discipline, but they lack the governance structures that give that discipline bite. They operate without the checks that private ownership provides, yet subject staff and students to the cost-cutting and efficiency drives that profit-maximising firms pursue. The result is waste at the top and insecurity at the bottom.

this is a very sharp piece on why it makes no sense to run universities as if they are businesses. They're not businesses.

since I first heard about LLM "silicon samples," I've been baffled by the idea. even if a group of humans were able to predict the behavior or answers of others, no one would use it instead of real data, cause there would clearly be unknown biases and situations in which the predictions would fail.

just found out that a study about chatGPT predictions of experimental condition effects that I was a tiny bit involved in was published - already a year ago 😅 ‍royalsocietypublishing.org/doi/full/10.... - even the now archaic gpt-4 did as well as humans, would be interesting to see current models

What does that mean?
Bad news: democratic views are even more fluid than recently shown. In times when we feel poorly, we evaluate opponents + institutions more harshly.
Good news: there are limits to this. Short-term changes in affect (eg traffic jam) won’t shift views or prompt intolerance

thanks to all attendees and panelists for a great discussion, and a special shout-out to Jeff for bringing up Imre Lakatos ❤️

funny how banning smartphones in classrooms has become one of the few things both sides agree on 🙃 however, the research was kind of flimsy... now a new big study out of India shows some benefits; especially for struggling students – although the overall boost looks small (about d 0.08)

it simply comes with the mid-century design ❤️

Experts of BlueSky: what are the best recent papers, studies & sources on mercenaries / private security companies, particularly how the field has evolved as business over the last few years? I'm interested in global examples, rather than just Western & Russian ones.

I've updated the marketing replication tracker through 2024. So far, 5 out of 45 (11%) of all direct replications of marketing studies (studies published in scientific marketing journals such as Journal of Consumer Research and Journal of Marketing Research). openmkt.org/research/rep...

Interesting read, even if worrying. Much more reliance on paid WoS in Czechia. But some promotion models started going the Scholar way. Maybe a mistake…

This thread. Sheesh.

although my priors regarding claims by @jburnmurdoch.ft.com are quite low, there seems to be a real d=0.4 difference (cf grimoiremanor.substack.com/p/no-conscie...) However, it's based on a non-representative convenience sample of online respondents, so no way to tell what is the cause...

A specter is haunting political psychology—a specter of left‐wing authoritarianism: Development and validation of left‐wing authoritarianism scale in a post‐communist society The position of left-wing authoritarianism (LWA), contrary to its right-wing counterpart, has long been contested within the psychological literature. Efforts to examine the nature of LWA have recent...

reading about left-wing authoritarianism (doi.org/10.1111/pops...) reinforced my pet peeve with political psych: treating ideology as a personality trait is doomed to fail as complex, context-bound worldviews can’t be meaningfully flattened into neutral questionnaire items...

Second, beyond career implications, doing open science & especially replications often comes with immense emotional burden & affects mental health. Ongoing harsh criticism, suspicion, & hostility, from senior scholars with immense power in the field, isn't something people normally want or look for.

the kind of flawed & dishonest critique that @lakens.bsky.social points out here ⬇️ is actually a neat example of moral persuasion: you cast one's motivation & character into a doubt which enables you to disregard everything they do or say as potentially tainted, without the need to engage with them
