What criteria are used in the investigation of alleged cases of research misconduct?

Research misconduct is a global concern. Considerable research has been devoted to guidance documents, but little attention has been paid to the empirical investigation of how (alleged) cases of research misconduct are addressed in real-life and which criteria are used to qualify a case as misconduct. Therefore, we performed a content analysis of 169 closed misconduct reports between 2007 and 2017 from Denmark, the Netherlands and Belgium, representing three different types of governance of research misconduct. This study showed that when considering a case of (alleged) misconduct investigating committees assess 1) the objective evidence of research misconduct, 2) the subjective intent of the person subject to investigations, and 3) case specific circumstances. We found that research misconduct was established in 15% (9/61) of cases in Denmark; 16% (13/82) in the Netherlands and 38% (10/26) in Belgium. 57% (35/61) of cases in Denmark, 49% (40/82) in the Netherlands, and 12% (3/26) in Belgium were deemed outside of the scope of the investigating committee. Our analysis improves the understanding of how investigations of (alleged) misconduct are handled by the investigating committees in Europe.
