Researchers studying integrity might be expected to be full of that rare quality. That’s why organizers of the sixth World Conference on Research Integrity, to be held in Hong Kong, China, in June, were surprised to receive an abstract that was, instead, full of apparent plagiarism. After combing through all 430 submissions, they discovered 11 additional cases of suspected plagiarism. When they reached out to the authors of the abstracts—two of which, ironically, were about plagiarism—six didn’t respond, one withdrew their submission, one blamed staff, and two said they had permission to use each other’s work. Only two gave “acceptable” explanations, the organizers reported last week on the Retraction Watch blog.
