While the non-disclosure of the conflicts of interest is a serious issue, it is also important to point out that

There is a tendency to minimise the implications of the recent retraction in PNAS of the Mariano Barbacid paper for non-declaring their conflicts of interest.
This is not a minor procedural oversight.
It touches a core structural principle of modern scientific practice: transparency as a prerequisite for credibility.
Conflict-of-interest disclosure is not a bureaucratic formality.
It is a mechanism designed to allow readers, reviewers, and the broader community to interpret data within its full economic and intellectual context. When omitted—particularly in cases where authors hold ownership stakes in companies positioned to commercially exploit the reported findings—the omission distorts the epistemic framework in which the results are evaluated.
We have precedent.
Both in Spain and the United States, high-profile cases have demonstrated the institutional consequences of such failures. A prominent clinician-scientist—former chief in leading hospitals across both countries and president of major international medical societies— resigned from positions in the United States after failing to disclose relevant financial conflicts, subsequently transitioning to the pharmaceutical industry.
The issue was not scientific fraud; it was a breach of transparency. Yet the reputational and institutional consequences were substantial.
There is an additional layer here that is often overlooked.
The publication in question was submitted under the “contributed” track available to members of the United States National Academy of Sciences. This pathway—effectively a form of editorial privilege—allows for an expedited and, in practice, more controlled review process. It is a mechanism unavailable to the majority of researchers, who must navigate standard peer review with no such structural advantage.
This episode is not about a single paper. It reflects a tension between scientific authority and scientific accountability. Prestige may facilitate access, but it does not exempt one from the foundational norms that sustain trust in the system.
