Reported numbers of observed scientific misconduct, e.g. through retracted articles, are increasing at an alarming rate. The detected cases, however, only present the tip of the iceberg because the actual amount of scientific misconduct is impossible to observe. Fraud in science is professionally and socially unaccepted and leads to sanctions for the culpable scientists so that misconducting scientists try to hide their fraudulent actions. This means that ultimately, the size of the population of misconducting authors remains elusive and, as such, presents a “dark number.”
We estimate the size of the population of misconducting authors in medical and health sciences, drawing on capture-recapture methods. We find that the population size of misconducting authors in medical and health sciences is about 4,000 and therewith much larger than the cases that are detected. This finding calls for more transparency through data sharing among peers and author responsibility assignment. (joint with Maikel Pellens)
