"At the University of Calgary, Griep’s handling of data also allegedly led to problems. So serious that he had to leave under a non-disclosure agreement." Deported into a Dutch professorship. Academia is harsh to fraudsters!

The study also doesn't account for insincere responses. Our recent paper showed most participants who endorsed two contradictory theories showed signs of insincerity (such as agreeing that the Canadian military are preparing a force of intelligent giant killer raccoons to invade nearby countries...)

That 91% figure isn't something observed in the study, it's an predicted probability of incoherent endorsements for participants sitting at the ceiling of the conspiracy scale. Which may have been few or no people in the sample.... academic.oup.com/pnasnexus/ar...

This paper looks excellent! I've been looking at a related issue with causal inference in qual papers. It seems common for qual papers to make causal claims based on participants saying they were affected by something.I'm not sure if there exists any epistemological stance for which that makes sense

The provost of Dartmouth, at which I teach, has been using AI to write both academic papers & national op-eds, according to brave reporting by @thedartmouth.bsky.social. Many students are already bitter about AI. This leaves us as faculty no ground to stand on. www.thedartmouth.com/article/2026...
thedartmouth.com
Op-eds, academic articles by Provost Santiago Schnell flagged as ‘AI-written’ by ‘near-zero error’ AI detector Pangram
Schnell said he used artificial intelligence for “making writing processes more efficient,” but that AI was not a “substitute” for his own “intellectual judgment or authorship.”

Forensic meta-science folks: What is the most efficient way to check an unpublished paper for tortured phrases (e.g., during peer review)? The Problematic Paper Screener website lists a number of software vendors but I'm struggling to find anything that I can use myself!

Ah, I meant the acceptance rate is too *high* to believe (given that median time to first decision). Even much less prestigious journals have much lower acceptance rates these days (lots of slop in editors' queues!)

Matt Williams @matthewmatix.bsky.social · 15/09/2026
The IF, possibly. They publish few articles and the ones they do seem to get cited lots, with a couple of huge outliers. But median time to first decision of 2 days along with acceptance rate of 31% can't be right. Might be calculated with different subsets of submissions (e.g. solicited vs total)

I definitely emphasize with your experiences and those of the grad students in that sample. But just a gentle reminder that we can't get valid causal inferences by asking people how they think they were affected by something. Better studies needed!

Angela Duckworth's clams about "Grit" - based on misunderstandings of factor analysis, odds ratios, measurement principles, and effect sizes. The level of incompetence still leaves my flabbers gasted - particularly since it sparked the whole "grit" movement in education. So many $$$ wasted.

The Recurring Speed Camera Discourse is a bit exasperating really because, look, we all know what's actually happening is people just want to be able to commit the pertinent crimes and don't like being punished for it, but people come up with obvious post-hoc pseudo-woke rationalisations for this.

*Criticism* of ideas is not the same thing as *censorship* of ideas. It's literally our job as scientists to criticize each others' ideas. That's how we make science stronger. We poke holes in hypotheses and point out potential harms so we don't waste resources or harm people with fallible ideas.
