We suggest that the mechanism underlying this phenomenon is stigmatization by mere association. The result suggests that scientific misconduct generates large indirect costs in the form of mistrust against a wider range of research findings than was previously assumed. The broad fallout of misconduct implies that potential whistleblowers might be disinclined to make their concerns public in order to protect their own reputation and career.
