INSPECT-SR – a tool for assessing the trustworthiness of randomized controlled trials – has been published today in @bmj.com, giving researchers a structured way to identify problematic studies before they're included in systematic reviews. 🔗 www.cochrane.org/about-us/new... #ResearchIntegrity
“Systematic reviews are only as credible as the studies they include.” — phrased as a Cochrane senior research integrity editor; a magnifying glass rests on stacked papers in the background to emphasize careful scrutiny of research.

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.”

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.
