"...deidentified data on 110,303 manuscript submissions over 5 years at Science and Science Advances." Key results: - Editors rejected 28.1% of submissions outright. - They sent the other submissions to an advisory board for feedback, and then rejected 75% of those. - If a paper makes it to peer review, then it will be accepted about one-third of the time. - Submissions from "more prestigious" schools are far more likely to make it past the editor. The benefit of being from a prestigious school goes down once the paper makes it to peer review. - Submissions from China are penalized (less likely to be accepted). Papers with lots of authors also have higher success rates. Note that all of these things are correlations, though; it is possible that papers from China are literally just worse on average, or that papers with large teams really are better, etc. - And they made the data available!
