Come join this project to study a form of peer review that focuses on the methods instead of the results. I'm already a postdoc on the team so hit me up if you have any questions!

@royperlis.bsky.social based on a study using Pangram to detect AI use in papers: "Less than 25% of authors using GenAI are disclosing its use" Why is this the case? Do people feel shame for using AI to improve their studies / papers? Do journals discourage (disclosure of) AI use? #PRC10

We found that the results of 42% of registered studies on the OSF are never publicly shared journals.sagepub.com/doi/10.1177/.... Most common reasons are null results and bad logistics. Plan your studies carefully (equivalence testing and good time management) to prevent research waste!
