In 2014, David Allison noticed something wonky with a paper in the journal Childhood Obesity. The article purported to find that children who regularly ate kids’ meals with toys inside  we won’t name them, but an example might rhyme with “shmappy shmeal”  were liable to consume excess calories. But Allison spotted that the researchers had incorrectly analyzed their data, causing them to exaggerate the effects by more than tenfold.

That realization prompted a letter from Allison, a biostatistician at the University of Alabama at Birmingham  which, in full disclosure, receives funding from the National Restaurant Association  and his colleagues. Several months later, the journal retracted the paper.

Hurray for science and its much-vaunted self-correcting mechanism, right?


If only.

In an article in Nature this week, Allison and colleagues report that such corrective action by a journal is far from the norm. Over a period of 18 months the group submitted corrections and retraction requests to 25 papers in a variety of publications and had one other successful retraction. A few other journals published their letters but did not retract the studies.


Mostly, though, Allison’s group found the effort a waste of time. “Too often, the process spiralled through layers of ineffective e-mails among authors, editors and unidentified journal representatives, often without any public statement added to the original article,” Allison and colleagues write.

The problem gets worse: “Some journals that acknowledged mistakes required a substantial fee to publish our letters: we were asked to spend our research dollars on correcting other people’s mistakes.” One unnamed publisher even had the gall to declare that it would exact a fee of $10,000 from authors of withdrawn papers  a draconian amount that clearly poses a disincentive to doing the right thing.

So this is the state of scientific self-correction in the 21st century. ­­Despite the opportunities for instant access to studies, international and public scrutiny, and rapid communication, getting a paper retracted or corrected turns out to be well-nigh impossible.

We’ve seen this ourselves in forwarded email exchanges between researchers bringing problems to journals’ attention and editors who, let’s say, pay less attention than they ought to. Some 500 to 600 articles are retracted each year, and while we wouldn’t hazard a specific guess as to how many more ought to be pulled, we’re confident that number is a multiple greater than what we’re seeing.

Take the case of cell lines, widely used in biomedical research for everything from testing drugs to seeing how our bodies work. It turns out that many researchers who did those studies were using the wrong cell lines, meaning that what seemed like a promising finding in kidney tumors was in fact a finding in cervical cancer. And yet the vast majority of those papers carry nary a warning.

Allison’s group calls out what they consider six critical problems with science when it comes to self-correction:

  • Editors move too slowly to correct or retract;
  • it’s hard to find out where to send criticisms;
  • when concerns are expressed informally, such as in comments sections of journal webpages, they rarely trigger action;
  • journals are loath to take action even when confronted with “invalidating” errors;
  • getting access to researchers’ raw data is a difficult and haphazard affair;
  • and, the whole charge-the-whistleblower thing.

To that list we’d add lawyers. In a refreshingly open 2014 editorial, Nature admitted that, when trying to correct the record, “journals might find themselves threatened with a lawsuit for the proposed retraction itself, let alone a retraction whose statement includes any reference to misconduct.” So that’s another disincentive for them to retract.

So what to do? Allison and his colleagues call on journals, publishers, and other players to standardize and streamline. “Address readers’ concerns swiftly,” they write. “Use formal expressions of concern as an alert that work is under scrutiny  rather than for condemnation.” Their recommendations make sense, although many of them are what journal editors insist  defensively, in our experience  that they already do. (And, in fairness, a number of researchers and editors have earned a place on our “doing the right thing” list.)

In the end, Allison’s group writes, “Robust science needs robust corrections. It is time to make the process less onerous.”

To which we say: It sure is.

  • I am the inventor of the first ion propelled aircraft in history to carry its power supply onboard please see US Patent No. 10,119,527 for flight videos, website, and patent and other data. I have worked on this project much of the time for the past 19 years.
    On about Nov. 22nd 2018 MIT submitted a paper and video to the Journal of Nature claiming they made the “first heavier than air ion propelled aircraft of any kind to carry its power supply.” Their claim is wrong! A significant percentage of the other claims in their paper are also factually wrong. The article has now been replicated in a world wide news blitz. I would like to see the paper amended or retracted. I have contacted the the editor of Nature, but so far he just suggested I pay to submit and write my own paper… He has not responded to my most recent email yet regarding a possible amendment or retraction to the MIT paper. To be fair, it has only been a few days since I sent my last email to him, but I wonder if any steps will be taken in this matter.
    The incorrect MIT paper and ultra-inefficient technology is obscuring any real progress in this field. If you have any suggestions on how to restore the historical record so that the truth is reflected, I would really appreciate it!
    Thanks a lot!
