Taylor & Francis has threatened legal action against an online group that has made allegations, based largely on vague insinuations rather than evidence, about the publisher and a member of its research integrity team. On September 7, the group published a string of claims on X about Nick Wise, a sleuth who joined Taylor & Francis in January as a research integrity manager. The ScienceGuardians post characterized the move as Wise “infiltrated” the publisher’s research integrity office. Among its “material concerns,” the letter cites “conflicts of interest,” referencing Wise’s PubPeer posts, and whether he “disclosed his PubPeer activity” to the publisher. “Your email and social media posts include several significant allegations about a particular individual at Taylor & Francis,” Alam wrote.
