This is equally true of quantitative data. Ethical and privacy management are essential parts of responsible data sharing policies and practices. Also, there are many alternatives to "pure" open sharing that help to address when confidentiality and transparency are at odds.

tl,dr; Scientists no longer allowed to use federal funding to publish, attend meetings, or talk to the public. They cannot collaborate internationally. Grants can be cancelled for any reason, at any time, political appointees have a final say over what gets funded, and who gets funded.

To me, this looks like a classic case of collider bias (aka selection bias): if papers are still published after having a major revision it's more likely to be papers with a higher latent citation rate compared to papers with a minor revision.

People often complain about tough peer reviews But papers that elicited stronger criticism from reviewers and required more-extensive revisions received more citations tha did papers that drew light comments and sailed through the peer-review process. www.nature.com/articles/d41...

Two new facts stand out: 1. 85% of hallucinated citations in preprints are also in the subsequent journal version (thanks, peer review!) 2. Fake cites more likely to use the names of (male) scholars who are already highly cited, creating a fake-citation Matthew effect. arxiv.org/abs/2605.07723
