CONFLICTS AROUND A STUDY OF MEXICAN CROPS

The editor of Nature is still ducking and diving over his "retraction" (the word he himself uses in his letter on this issue to The Guardian - https://members.tripod.com/~ngin/deceit6.html) of Chapela and Quist's paper on Mexican maize contamination.

His claim that the paper's "principal conclusion is shown to be not necessarily false but unsustainable on the basis of the reported evidence" is directly contrary to the evidence available as to the majority view of the peer reviewers who looked at this issue and concluded that the paper's principal conclusion had not even been challenged.

As the BBC's Newsnight programme showed:

(Newsnight) ...He retracted the whole paper although the main conclusion, which Nature itself press released as "scientists have detected transgenic DNA in wild maize" was unchallenged.

(Campbell) in terms of what we published as far as I'm aware the first part of the paper hasn't been disputed...

(Newsnight) But you still felt it necessary to retract?

(Campbell) Uh hum yes...

(Newsnight) can you tell me why exactly....

(Campbell) yes because as I said the paper as a whole shouldn't have been published -

(Newsnight) Chapela's supporters thought Campbell was responding to pressure from industry-funded scientists, but he denies this. He sent the paper to three referees before deciding whether to retract. Newsnight has obtained their confidential comments. Only ONE thought the paper should be retracted - though all said there were flaws in its second part.

The second referee said "none of the critics seriously dispute the main conclusion" and the third said "none of the comments has successfully disproven their main result that transgenic corn is growing in Mexico and crossing with local varieties". Yet Campbell published the retraction -citing only the FIRST referee.

The editor's action remains incomprehensible outside of the industry-orchestrated campaign of pressure to force a retraction.

As Worthy et al note below, "By taking sides in such an unambiguous manner, Nature risks losing its impartial and professional status. This is particularly troubling when articles are related to economic or political interests. Nature asks its contributors to provide information regarding conflicts of interest, but does Nature hold itself to the same standards?"

Metz et al's claims below to be free of any undue influence relating to the Berkeley Syngenta deal and the controversy over it has already been exposed as laughable by the investigation into these issues by The New Scientist amongst others. https://members.tripod.com/~ngin/130602a.htm

Scientific endeavour is based on formation and testing of hypotheses. Very few hypotheses persist unmodified after they are first proposed; most are tested, modified and re-tested, and often refuted. Many journals include a forum for scientists to make technical comments on recent publications and for the original authors to respond, so that readers can evaluate the merit of reported scientific findings.

The cornerstones of a rigorous publication process are the subject editor, who is familiar with the research area of a submitted manuscript, and the independent outside reviewers whose recommendations are solicited by the subject editor. This thorough evaluation ensures, to some extent, the journal's impartiality in publication decisions.

Despite this rigorous process, however, Nature recently published a technical exchange1-3 accompanied by an editorial note stating: "Nature has concluded that the evidence available is not sufficient to justify the publication of the original paper".

The authors state that in their view this statement reflects poorly on Nature's editorial policy and review process, and sets a dangerous precedent. Why has Nature refrained from releasing similar editorial retractions of earlier publications later found to be incorrect or open to alternative interpretations? What sets this particular publication apart?

If the interpretation of the results proposed by the authors of the original paper4 was judged by Nature to be sufficiently erroneous to warrant this editorial statement, why did Nature publish the report in the first place?

By taking sides in such an unambiguous manner, Nature risks losing its impartial and professional status. This is particularly troubling when articles are related to economic or political interests. Nature asks its contributors to provide information regarding conflicts of interest, but does Nature hold itself to the same standards?

The editor of Nature comments that it is highly unusual for Nature to publish a paper whose principal conclusion is shown to be not necessarily false but unsustainable on the basis of the reported evidence. The paper was not formally retracted by its authors or by Nature. In the circumstances, Nature considered it appropriate for the record to make clear to readers its revised view of its original decision to publish.

The independence of our editorial decision-making from partisan anti- or pro-technology agendas and from commercial interests is paramount in our role as a journal.

Editor, Nature

Matthew Metz, Department of Microbiology, University of Washington, Seattle, Washington 98195, USA, and Johannes Fütterer, Institute of Plant Sciences, ETH, CH-8092 Zürich, Switzerland, reply that the accusations of Worthy et al. about their Brief Communication1 do not relate to the scientific data of Quist and Chapela4. Metz and Fütterer say their concern was exclusively over the quality of the scientific data and conclusions, which would have been the same whatever the motivation of the criticism.

Bad science can only undermine our understanding of nature, and the making of constructive public policy. The statement that "commercially vested interests" (that is, ties to Syngenta/ Novartis) are "central to" criticisms of the data in ref. 4 is as useless in addressing the scientific issues as would be an accusation that these data were tainted by a grudge between Chapela and his former employer (the same company). Metz and Fütterer state that although their connections to industry are irrelevant to the scientific issues, and hence do not warrant disclosure, we feel compelled to dispel the mischaracterization of Worthy et al.. One of us (M. M.) had TMRI funding for only one-sixth of his study at UC Berkeley, and the other's (J.  F.) alleged link to TMRI relies entirely on someone else's former Berkeley association. Both Metz and Fütterer currently have research funding exclusively from the public sector.

We are not unlike many scientists in that we have shared research and funding with industry at some point. In stating that we have "compromised positions", Worthy et al. wrongly imply that private-sector funding strips us of integrity and legitimacy in the arena of scientific discourse. Far from promoting "scientific freedom and balance", this presumption tars any scientist who can be suggested to have worked with the private sector. The only threat to academic freedom that seems to have materialized from the Berkeley/TMRI collaboration is this attitude towards scientists who might have industry links.

Nick Kaplinsky of the Department of Plant and Microbial Biology, University of California, Berkeley, California 94720, USA, replies that he, on behalf of the authors of the Brief Communication2, state unequivocally that funding from TMRI has absolutely nothing to do with their criticisms. Worthy and co-authors are incorrect. Two of Kaplinsky's co-authors of ref. 2 (Hake and Hay) do not receive any industry funding. Funding information for the Freeling lab (Braun, Freeling, Lisch and N. K.) is transparent and public (see http://plantbio.berkeley.edu/~freeling/labweb/fund.html); less than a quarter of it is from industry.

As Worthy et al. state, Chapela and Quist are "leading critics" of the TMRI agreement. Chapela is a board member of PANNA
(http://www.panna.org/panna/about/board.html#ihc), an advocacy group opposing genetically modified organisms (GMOs). It is a double standard to accuse us, but not Quist and Chapela, of a conflict of interest.
