There is a common belief that commentary papers don't get cited + aren't worth writing. But the data says otherwise! Commentaries published in Association for Psychological Science tend to attract 25% as many citations as their target article. Some are cited even more than the original!

Wanna know whether #preregistation 'works' in psychology and what that even means? You can read about it in my PhD-dissertation here: osf.io/f4cx7 Or check out this talk in which I summarize the results: youtube.com/watch?v=f-yCGW… Defense is planned for 22 March! 😱

We devised a new way to let researchers use patient's confidential medical records in research, while ALSO preserving their privacy. How does OpenSAFELY work? We made a 5 minute video! youtube.com/watch?v=GRjRqO…

New blog post by Robert Thibault about his experiences with what works and what doesn't in relation to group authorship (i.e., just having the name of the group listed instead of individual authors, e.g. "Open Science Collaboration"). blogs.lse.ac.uk/impactofsocial…

"Our results suggest that preregistration is a credible signal for the integrity of clinical trials, as far as it can be assessed with the currently available methods to detect p-hacking." medrxiv.org/content/10.110…

Do pre-registration & registered reports reduce research waste? (spoiler, YES, based on 26 meta-studies) Would love to get your feedback, especially on proposed measures to increase registration in ecology Read more ecoevorxiv.org/repository/vie… nature.com/articles/s4155… DM for PDF

Question: is there sufficient guidance to improve the transparency of studies that make secondary use of health data? Answer: There is quite some for registration and methods reporting but not much for data and code sharing. Moreover, caveats are often glossed over. #WCRI2024

If you are skeptical about the quality and validity of science, the last thing you should cut are initiatives aiming to make science more transparent!
