In a national survey on research integrity by Dutch academics, 40,000 researchers, from PhD students to full professors, admitted to committing at least one of the 11 questionable research practices. One in 12 researchers is estimated to have fabricated or falsified research results in the last three years. According to a postdoctoral researcher and lead investigator of the survey, findings are already being discussed with policymakers in universities and medical centres in the Netherlands.
