The few scientists conducting peer review for predatory publishers are often of young academic age and come from lower-income regions
An analysis of almost 200,000 peer reviews found that although less than 3% of academics regularly review studies for predatory journals, those who do are usually in the early stages of their academic career and based in developing countries. Writing these reviews is likely to have taken around 30,000 hours – time researchers wasted on studies with little to no scientific impact.
