📷New blog post: Where Papers Go Before (and After) rejection at a top field journal? This blog post explore this and more. One key finding is that desk- and referee-rejected manuscripts end up getting published at roughly the same rate elsewhere. https://t.co/Rd44KT5WSh

🚨New blog post: Replicators, rejoice! Episode 1 of the new series is out: “A New README.” A practical guide to transforming messy project folders into clear, well-structured documentation that strengthens transparency and reproducibility. See more at https://t.co/YgLiy4jcul

We believe reproducibility is the cornerstone of trustworthy science, which is why we will be systematically reaching to authors, building replication packages, and testing robustness directly. See more at: https://t.co/69Mhfm6JKb

In our latest post, we explore what happens when data and code go missing: Out of 553 public health studies, only 19.3% made their data public In economics, the situation is better but far from perfect: 46.7% of studies have a full replication package...

🚨New blog post: The Reproducibility Gap in Tropical Disease Research Tropical diseases remain one of the greatest global health challenges, yet much of the evidence guiding interventions may not be as reliable as we assume...

Last Friday we held Munster Replication Games (@uni-muenster.de jointly with #MüCOS and #CDSC). Sixty researchers replicated fifteen papers: well done, everybody! Many thanks to the local organizers as well, Bernd Schlipphak, Lukas Röseler and Katrin Schmietendorf :)

We won't be releasing any additional info on social media until the situation is resolved with lawyers, but will keep releasing reports through our DP series. Here are two 40-page reports completed earlier this year. https://t.co/JwxdZ14Oko https://t.co/vKvJoYojpg

Surprisingly, I4R has never been contacted by any of the authors' universities/funders. This is disappointing given that we documented irregularities in 10+ lengthy reports. That's easily 300 pages of data irregularities.

We also heard that one university conducted an internal investigation. It appears they concluded no wrong doing.

To clarify, I4R has not been contacted by the authors' lawyers. The journals/publishers have. We won't reveal which journals and appreciate all the (amazing) efforts their editors have made!
