11. Journal Retractions In a study of retractions in biomedical journals, 436 were due to error, 201 were due to plagiarism. 888 were due to fraud. 291 were duplications of publications, and 287 had other causes (based on data from “Misconduct Accounts for the Majority of Retracted Scientific Publications,” by Fang, Steen. Casadevall, Proceedings of the National Academy of Sciences of the United States of America. Vol. 110, No. 3). Among such retractions, does misconduct (fraud, duplication, plagiarism) appear to be a major factor?
