Programming Note: Nobel Predictions Video Roundtable

Wednesday, October 2nd, 2013

ChemBark MedallionHello friends.

I’ll be participating in a video roundtable discussion tomorrow/today (Thursday) at 3 PM Eastern US time. The discussion will focus on Nobel Prize predictions and general thoughts. The event is being hosted by reporters Carmen Drahl and Lauren Wolf at C&EN, with me, Neil Withers (Chemistry World), and Simon Frantz (BBC Future, formerly NobelPrize.org) as guests.

There’s more info here, including a link to the broadcast. Tune in and see why I normally stick to writing: I’m ugly and have a horrible nasal voice.

It’s going to be grand!

Edit to add: Here’s the video from the session:

Chemistry World and Others on Dodgy Data

Thursday, September 5th, 2013

ed_baseballcap_150Hello, friends. Pardon the radio silence of late. My first semester of teaching just started at SLU and my head is already spinning. I’ll have a full post on that subject soon, but I wanted to weigh in on a few recent pieces regarding the cases of suspicious data that were reported here and elsewhere.

Reporter Patrick Walter wrote a story earlier this week for Chemistry World that examined whether blogs are appropriate venues for policing the chemical literature for misconduct. I was interviewed for—and quoted in—the story, which I feel is thorough, is balanced, and represented my positions accurately. As you might imagine, I argue that blogs are indeed appropriate venues to report suspicious data and to analyze how the community should respond to misconduct.

There are plenty of people who disagree with me—to varying extents—and the article raises their concerns as well. That is fantastic, because this is a discussion that we need to have. I am happy to engage in thoughtful debate on the subject (see posts here and here) in hopes that we, as a community, can arrive at a more efficient system for removing manipulated data from the literature and preventing their publication in the future.

Mitch André Garcia, who runs both Chemistry-Blog and the chemistry subgroup of Reddit, is one of the people who took exception to my post on the manipulated spectra in Organic Letters. Here is what he wrote on Twitter:

I’m left scratching my head here. How do the nanochopsticks he reported qualify as “acceptable to cover” for being “egregiously manipulated and…in a high impact journal” but not the erased impurities in the Anxionnat/Cossy spectra reported here? Seems pretty hypocritical. And if we can’t agree on whether these cases meet his standard for “egregiously manipulated” and “high impact”, how are we supposed to agree on anything?

My view on the matter is that anyone who wants to raise concerns publicly about data may do so, with the full realization that they are putting themselves on the line. If I raise concerns about the integrity of data in a paper, I am accountable to defamation law and the high intelligence and ethical standards of the readership here. I can only bring information to people’s attention. If that information is wrong or doesn’t support my opinions, I will be excoriated in the comments and lose credibility. If what I publish is defamatory, I will probably also be sued. The root cause of the outrage among chemists about these papers cannot be attributed to blogs; the data speak for themselves.

A few days ago, John at the blog It’s the Rheo Thing posted some cautionary advice to “activist [bloggers] that are confronting examples of fraud, plagiarism and other publishing infractions in the technical literature”:

What goes around, comes around. Many are pleased to bring the axe down hard on someone’s head, and hold as many people responsible as possible (from ALL the authors to the principal investigator and maybe even beyond that), but we need to keep in mind that publishing scientific research is a human effort and as such, will be imperfect at times even when no harm, deceit or other nefarious activity is intended. Many of the commentators screaming for blood are young professionals you have yet to run a large, established research group, but who think that they will be able to do so flawlessly in the future. Of course that won’t happen. You will have failings and shortcomings and things will go wrong despite your most fervent intent to prevent it. Most people do not have a problem with that.

Most people. But there will be plenty of others wanting your head on the same chopping block and with an added level of glee since you were responsible for bringing so many down yourself. It’s human nature. We can’t change it, this perverse desire to bring down the people bringing down others. Worse yet, these efforts to trap you may be entirely without merit. That won’t matter. “A lie can travel halfway around the world while the truth is still putting on its shoes” (Mark Twain). Your name and reputation can be placed in the same trash heap as those truly deserving it far more easily than you can ever imagine. Despite your noble intents and purity of heart.

User “juicebokz” on Reddit called John’s post “a letter to ChemBark”, and I feel compelled to weigh in with the following points:

Do you seriously think that the responsibilities of running a modestly popular blog don’t weigh on me? Do you think that I don’t consider whether I am treating the subjects of these sorts of posts fairly? These posts are not aimed at destroying scientists; they are aimed at protecting science. I do not take joy in the downfall of others, but I am not going to let a miscreant’s potential downfall prevent me from discussing a topic that I feel is important. Should any researchers be “brought down” for data fabrication, I will not be the person responsible for bringing them down. They will have been the people responsible for their own downfall.

And I am by no means a perfect person. Everyone makes mistakes and does things of which they are not proud. The point is that you have to pay for your mistakes, then dust yourself off and go about living a productive life. Should anyone gather the motivation to search through my past, or present, they’re going to find stuff that will embarrass me…but they are not going to find any fabrication of data.

As for drawing attention to co-authors who very likely did not actively participate in the fabrication of data, I still stand by the position that authors must share the responsibility for the content of their papers. “Share” does not mean “share equally”, but all authors should at least read through their papers and keep an eye out for things that are obviously wrong. When you are a corresponding author, ensuring the integrity of the data in your papers must be one of your priorities. If you think I’m alone in this view, please go back and read Smith’s editorial in Organic Letters. Any punishment doled out regarding fabricated data in a paper should be proportional to (i) one’s active involvement in the fabrication and (ii) one’s responsibilities as a conscientious scientist and/or manager. These responsibilities should be the subject of more discussion among chemists.

Finally, does anyone really think I am helping my career by reporting on scientific misconduct? Do you have any idea how uncomfortable it is to send e-mails to the editor-in-chief of a high-impact journal in my field asking for comment about how he’s going to deal with manipulated data in a paper written by one of his associate editors? Was it lost on people that Smith’s response to my inquiry was addressed “Dear Bracher”? It’s certainly not the most cordial of salutations. I asked a follow-up question by e-mail and was not given the courtesy of a reply.

I don’t like these sorts of awkward interactions, but asking hard questions is part of doing a thorough job of reporting, so I’ll just bite the bullet. I can only hope these interactions don’t come back to hurt me down the road, but that’s a possibility. At the end of the day, I would love not to have to write about scientific misconduct because (i) chemists have stopped doing it or (ii) universities, journals, and government have created a good system for dealing with it.

Now, how do we make that happen?

How Should the Online Community Handle Suspicious Papers?

Saturday, August 17th, 2013

The latest news regarding the Dorta paper in Organometallics is that Emma Drinkel’s mother wrote an e-mail to Fredrik von Kieseritzky that is posted to his chemistry blog, Synthetic Remarks. You will recall that Emma Drinkel was the first author on the OM paper, and she was on the receiving end of the infamous instruction to “just make up an elemental analysis”.

Dr. Drinkel’s mother wrote:

From: Mary-Anne Drinkel [mailto:xxxxa@xxxx.co.uk]
Sent: 15 August 2013 21:04
To: Fredrik von Kieseritzky ‘xxx@xxx.com’
Subject: Emma Drinkel – the Dorta Affair

Dear Dr Kieseritzky

I hope you don’t mind me contacting you, but I would just like to thank you for your comment on ChemBark. My name is Mary-Anne Drinkel, and I am mother of Emma. We are very proud of our daughter she has worked hard and conscientiously to earn her first class degree at Durham, her PhD at Zurich, and presently her Post doctorate work in Brazil- we know that fabricating data would be alien to her. I cannot believe that her good reputation, built up over these years can be destroyed in a week. I know nothing of the academic community, but the hostile and aggressive comments left on the blog sites are unbelievable. I don’t know if Reto Dorta was careless or has done a very bad thing, but I do know that Emma is the innocent party in this affair. How many PhD thesis could withstand the hostile scrutiny that Emma’s has been subjected to, with these bloggers determined to find evidence of wrongdoing – boasting about who broke the news first.

Emma’s husband has a new industry position in Switzerland, and they will be moving back to Europe very soon; this means Emma will be applying for jobs – she fears this affair will affect her chances, as she would be honest with prospective employers about her situation. They had decided to leave the academic world long before this episode because the competitiveness and political environment of university life was not for them. Emma is devastated that her good name at Durham and Zurich University will be forever tarnished by this affair.

My husband and I have felt so sad and so helpless as these events have developed – when I saw your comment that was sympathetic to Emma’s plight, it was the first bit of humanity I had witnessed in the whole affair, and I am grateful to you for that. Emma will get through this, she is resilient and has the support of her husband, family and friends – but we feel so angry that Emma has been subjected to this through no fault of her own.

Once again thank- you,

Best wishes,

Mary-Anne Drinkel

I sympathize with Dr. Drinkel, but when you are an author on a paper, you share responsibility for its content. This responsibility is especially serious for the first and corresponding authors on a paper. With that said, it could easily turn out that Dr. Drinkel’s only transgression might have been a failure to carefully read the published version of her article—which most chemists probably don’t do anyway.

As it stands, it is impossible and unproductive to attempt to assign blame to specific people. We don’t know who wrote what parts of the paper, who was responsible for submitting it, and who reviewed the galleys. What we do know is that the paper is suspicious. It is a fact that the editorial remark to “just make up an elemental analysis” was published in the Supporting Information. It is a fact that the elemental analysis data in Dr. Drinkel’s thesis are different from the data presented in the paper.

The integrity of data is the foundation of scientific research. The community has a serious interest in maintaining the integrity of its data and pointing out cases where the validity of a particular set of data should be questioned. I don’t think that investigations into possible misconduct are best left solely to journals and universities. Time and time again, we have seen journals state that they do not have the resources to conduct thorough investigations of suspicious data, and once they have acted, the punishments are never made public. Where is the accountability?

Universities, often by law, are required to conduct thorough investigations of possible scientific misconduct. But the details of these investigations—even when they definitively identify egregious misconduct—are also often swept under the rug. It can be pointed out that journals and schools have little incentive to identify and publicize misconduct that has occurred on their watch. The community is not served well by this secrecy, and there would seem to exist an important void in the process for journalists, blogs, and social media to fill. These stakeholders can help identify suspicious data, misconduct, and the scientists responsible for it.

On the flip side of the coin, when suspicious data or behavior are identified, scientists who have not engaged in misconduct can get dragged in the mud. There will always be people who read a blog post on a suspicious paper and lump all the authors together without much thought. Obviously, Dr. Drinkel’s mother—as well as another commenter—is upset with my coverage of her daughter’s paper. My question is how would they have handled this situation and similar ones in the future?

The Committee on Publication Ethics has developed a set of recommended procedures for journal editors to deal with suspicious papers. How should chemistry blogs write about them? Should we just post links to these papers without comment? Should we write about them but close the posts to comments? Should we moderate the comments to remove unfair opinions and speculation? Should we black-out names and delete comments that attempt to identify the authors? Should blogs avoid writing about suspicious papers altogether and just rely on journals and universities to tell the community what they think we should know?

I bet there are a variety of opinions out there; I would love to hear yours.

Some VERY Suspicious TEM Images in Nano Letters

Wednesday, August 14th, 2013

Mitch at Chemistry-Blog has a new post about a set of very suspicious TEM images that was published recently in the journal Nano Letters.

The associated paper reports the fabrication of pairs of gold nanorods in “chopstick” structures where the two rods touch at their tips and form an angle that the authors say they can tune. Some of the TEM data can be viewed for free in the associated SI file. If you zoom in on the images, it appears that the background immediately around many of the rods is different from the rest of the background field. Hmmm…

User “spookyjeff” on the chemistry subgroup of Reddit commented:

That is some impressively bad photoshop. Allegedly.

To which user “FubarFreak” replied:

I’m going to go with MS paint

Mitch also reports that Leonard Pease, the last author on the paper and an assistant professor at the University of Utah, told Mitch “an investigation [is] underway at the University of Utah into this matter and [he] strongly encouraged [Mitch] not to publish this story until the University completed its investigation.” Pease also “informed [Mitch] that legal action might be pursued by the University of Utah if [he] published this story.”

Longtime readers of ChemBark will recall that Columbia University never explained to the community what happened after it was finished with its investigation of Bengu Sezen. FOIA requests filed by ChemBark and another news organization were required to report the full extent of Sezen’s misconduct to the public. One lesson there [of many] was that you cannot count on universities to investigate or publicize the results of investigations into suspicious data and other possible scientific misconduct. Journalists, sources, blogs, and social media have helped fill this void by making valuable contributions toward identifying suspicious data and ensuring research misconduct is investigated and punished.

Fortunately for Mitch, ensuring that one’s facts are true is an absolute defense against libel in the United States, and the truth is that the above images were published by the authors in Nano Letters.

Finally, if the images in Nano Letters turn out to be manipulated, we should consider the question of “just how lazy/inept was the offender?” Michael on Facebook tried his hand at “fixing” the authors’ figures and produced the following:

Very nice—no more boxy awkwardness and mismatched backgrounds. He reports that “after installing the photoshop trial it took about 5 minutes to do 2 or three images.”

Nice…

 

Of course, it’d be even nicer with safety glasses.

Also, beautiful new labs. Yum.
