Single-blind vs double-blind peer review and effect of author prestige

Scientists have examined if bias with single-blind peer review might be greatest in the setting of author or institutional prestige. The authors found that reviewers were more likely to recommend acceptance when the prestigious authors’ names and institutions were visible (single-blind review) than when they were redacted (double-blind review), and also gave higher ratings for the methods and other categories. There was no difference in the number of errors detected.
