Why retracted articles can have an influential afterlife-and what to do about it.

Retractions of published journal articles are an increasingly common means by which the research community ensures the quality and integrity of publications and addresses research misconduct missed during pre-publication peer review. Retractions are intended to notify the public of issues that undermine the integrity of these publications so that readers will not rely on their findings and conclusions. Continued citation and other uses of these publications without acknowledging their retracted status are therefore problematic and suggest shortcomings in retraction processes. In this commentary, we use the examples of retracted articles published in this journal to outline ways in which retracted articles can maintain an influential afterlife in the academic literature, online materials from non-profit organizations and private businesses, and responses from generative artificial intelligence. Given that this ongoing influence compounds the harms of these publications, we recommend changes in how publishers manage article retractions. These changes include ensuring that article retraction notices are maintained when journal publishing agreements change, increasing the visibility of retractions, and notifying scholars and members of the public when an article they reference is retracted. While these changes will make article retractions more effective, there is a continued need to limit the publication of studies that violate the requirements of research integrity.
