Problemen rond wetenschappelijke integriteit halen zelden de media. Dinsdag vertel ik waarom dat problematisch is voor het publieke vertrouwen in de wetenschap en de media, bij een colloquium van @isis-radboud.bsky.social, @willemhalffman.bsky.social. Ook @elisabethbik.bsky.social is van de partij!

I just reviewed the article 'Analysis of citation dynamics reveals that you do not receive enough recognition for your influential science' by Salsabil Arabi, Chaoqun Ni and @bihutchins.bsky.social.

Article: www.biorxiv.org/content/10.1...

Review: prereview.org/reviews/1733...
Most influential papers are published in lower-impact factor journals

I like the empirical work done by the authors, but I disagree with the interpretation they give to their findings.

Thanks, Johan, this is indeed something we'd like to explore!

We started @metaror.bsky.social MetaROR.org in part because of the absence of a journal that publishes metascience. But rather than a traditional journal, as metascientists we wanted to explore the next frontier - Publish, Review, Curate.

🆕 Our latest study asks how authors incorporate the PRISMA guideline into workflows when conducting reviews.

Both reviewers highlighted the study's importance yet also requested more information and details from the author.

🎙️ "Are we nearly there yet?"

Our colleague @alexrushforth.bsky.social joined the very first episode of the podcast series Fairly Recognised by the Dutch Recognition and Rewards programme to discuss the role of academics in research evaluation.

Tune in! 👉 sanlifaez.substack.com/p/are-we-nea...
Are we nearly there yet?
Six years into the national recognition and rewards program, and with all the support from the top management, can we talk of a behavior change on the work-floor?

Going forward, preprints will form the basis of @hhmi.org assessments of its researchers’ work.💪

Starting January 1,2026, HHMI will require its scientists to post their research articles as preprints under an open license that allows unrestricted reuse (CC-BY-4.0).

It is *so* exciting to see HHMI's new preprint policy. HHMI researchers are now required to post initial and revised preprints under CC-BY licenses. Best of all - the policy lets HHMI put preprints at the center of its research assessment strategy. Learn more:

Very glad to see the ANU Journal of Law and Technology has agreed to be @metaror.bsky.social's first partner journal from the field of law: cms.metaror.org/partner-jour...
MetaROR partners accept MetaROR reviews as part of their editorial process, making the publishing ecosystem more efficient.

"important aspect of HHMI policy is requirement for scientists to post initial preprint and revised preprint drafted following peer review. New policy thus recognizes importance of peer review, but as process in which authors receive and respond to feedback ... rather than as certification decision"

New policy at SocArXiv: We now require the submitting author to have an ORCID linked from the OSF profile page, with a name that matches that on the paper and the OSF account.
