Perceptions of plagiarism among PhDs across the sciences, engineering, humanities, and arts: Results from a national survey in Brazil

Plagiarism allegations are not rare in the history of science, and credit for prior work was and continues to be a source of disputes, involving notions of priority of discovery and of plagiarism. However, consensus over what constitutes plagiarism among scientists from different fields cannot be taken for granted. We conducted a national survey exploring perceptions of plagiarism among PhD holders registered in the database of the Brazilian National Council for Scientific and Technological Development (CNPq). This survey was sent to 143,405 PhD holders across the fields, including biologists, physicists, mathematicians, and engineers as well as linguists, philosophers, and anthropologists, with a 20% response rate. The results suggest that core principles about plagiarism are shared among this multidisciplinary community, thus corroborating Robert K. Merton’s observations that concerns over plagiarism and priority disputes are not field specific. This study offers insight into the way plagiarism is perceived in the research community and sheds light on the problem in the context of international collaborative research networks. The data focus on a particular research system in Latin America, but, given the cultural similarities that bind most Latin-American nations, these results may be relevant to other PhD populations in the region and should provide an opportunity for comparison with studies from other emerging, non-Anglophone regions.
