The world's largest multi-disciplinary research integrity survey is at risk of failing to achieve its objectives with two-thirds of the institutions invited to collaborate having declined to participate because of the sensitivity of the subject and fear of negative publicity. As a result, the researchers who conducted the Dutch National Research Integrity Survey found themselves alone in scraping up many e-mail addresses and soliciting responses. They gathered feedback from less than 15% of the 40,000 targeted participants.

On September 24, 2017 the Dutch newspaper de Volkskrant reported on an investigation into self-plagiarism (zelfplagiaat) that was conducted by a Nijmengen research group. The sociologist of science and his PhD student analysed 922 publications by Dutch researchers from recent years. In economics, 14 % of the papers contained text from previous publications of the author(s), in psychology the figure was 5 %. They even found a duplicate article republished with just one small change, and two highly similar articles by the same author in the same issue of a journal. They also found that authors who publish more papers are more likely to reuse text.
