German anaesthesiologist Joachim Boldt has an unfortunate claim to fame. According to Retraction Watch, a public database of research retractions, he is the most retracted scientist of all time. To date, 220 of his roughly 400 published research papers have been retracted by academic journals.
Boldt may be a world leader, but he has plenty of competition. In 2023, more than 10,000 research papers were retracted globally – more than any previous year on record. According to a recent investigation by Nature, a disproportionate number of retracted papers over the past ten years have been written by authors affiliated with several hospitals, universities and research institutes in Asia.
