Scientists in developed countries provide nearly three times as many peer reviews per paper submitted as researchers in emerging nations, according to the largest ever survey of the practice.
The report — which surveyed more than 11,000 researchers worldwide — also finds a growing “reviewer fatigue”, with editors having to invite more reviewers to get each review done. The number rose from 1.9 invitations in 2013 to 2.4 in 2017…
The report notes that finding peer reviewers is becoming harder, even as the overall volume of publications rises globally (see ‘Is reviewer fatigue setting in?’).
File under “the cost disease strikes back.” Furthermore, it seems increasingly obvious that a lot of lesser journals just don’t matter, and that may discourage prospective referees from putting in the effort. And note:
In 2013–17, the United States contributed nearly 33% of peer reviews, and published 25.4% of articles worldwide. By contrast, emerging nations did 19% of peer reviews, and published 29% of all articles.
China stood out — the country accounted for 13.8% of scientific articles during the period, but did only 8.8% of reviews.
