Scientists can be arseholes spending public money and emitting tons of greenhouse gases to be at a conference they don't need, while funding dries up for open infrastructure that we do need.
Anyone know of an initiative to donate confererence budget to save platforms like OSF and ResearchEquals?

Makes me laugh when people don’t go to conferences for the content or the networking, but they go anyway just for the opportunity to have their calendar show “busy” so they can lock themself in a hotel room and get some work done

The question that’s dominating the field is not a causality question. It’s really, how can one sell a causal relationship while crafting the language so that there’s plausible deniability when somebody criticizes anything.

A correction to a 2026 Nature paper. This is PubPeer working quite well (in my view at least). I spotted the error and the authors corrected the paper and replied on PubPeer to update. If I had to complain I would rather the correction referenced the PubPeer comment.

Journals should stop offering to store supplemental information. Everything that is shared with a paper should have it's own DOI, and live in a proper repository. As authors, link to files (e.g., Zenodo), but never add them as supplemental files.

The latest from me for The Skeptic, about how eugenicists are misrepresenting criticism and hijacking arguments around academic freedom, to launder racist arguments into academic discourse - and how some prominent skeptics fell for it.

Are there institutions yet that fully acknowledge that we need to take action on the peer review system?
Leadership in my institution is still at: reviewed at high impact journal = good science, only preprint = untrustworthy
Action comes from coordinating libraries in NL pushing for preprints.

I don't understand why researchers studying peer review don't more often become activists like researchers on climate change do.
You want to change your institution if it claims that climate change is nothing to worry about. Why wouldn't you if your institution claims no worries about peer review?

retraction should not depend on evidence of fabrication/falsification. The key issue is whether the editors have confidence in the data. And for an article with strong potential for public harm it’s negligent of the journal to set such a high bar. #JAMA
The request — which initially included two of the paper’s original authors — stems from 19-year-old court records revealing the sponsor of the study withheld evidence about opioid withdrawal that contradicted the paper’s conclusions.

Excellent. Even allowing for what I presume was some up-front notice that the Data Colada posts were coming, this retraction has happened between 10 and 100 times faster than the (ludicrous) current average. I hope this becomes the new normal, at SAGE and beyond.
Psych Science has retracted Ariely & Wertenbroch (2002). The second author requested the retraction. Both authors agreed to it.

We’re so close to a solution! Most unis have an institutional repository. If outputs were always published on the lead author’s repo, learned societies reviewed and curated them, their overlay journals just pointed at them, and everything had a DOI, what would we need commercial publishers for?
