Summary
Investigative medical reporter Maryanne Demasi breaks down the major problems within scientific publishing, including issues with peer review and pre-prints, politicization of scientific journals, scientific censorship, and diminishing trust from readers.
Demasi highlights arguments from various critics, such as former British Medical Journal editor Richard Smith who proposes that peer review often passes over ground-breaking research and regularly fails to detect fraud.
Smith acknowledges that established journals hold sway, particularly for junior researchers looking to build their academic careers. While Smith still sees a need for medical journals, he advocates for alternative publishing methods, like Substack. Some experts, like John Ioannidis, are concerned about the potential fragmentation of scientific literature with these new publishing models emerging. Ioannidis and advocates for a unified, comprehensive body of research.
.
The discussion also uncovers worries about the declining trust in medical journals and medicine at large over recent years, owing to factors like the politicization of science and scientific censorship during the Covid-19 pandemic. Ioannidis brings up the potential inaccuracy of many published research findings, the rushed sloppiness of much early Covid-19 research, and the spread of mis- and disinformation.
While both traditional and self-publishing methods have their supporters and detractors, the central issue revolves around enhancing the credibility, integrity, and accessibility of medical research. Moving forward, the scientific research community needs to assess how to best identify and communicate scientific findings to the public in an accurate and effective manner.
Many scientists are thinking about how research is fact-checked and shared with the world. In this article, we hear from scientific journal editors, a.k.a the people that decide what goes into research journals. Research journals are sort of like newspapers or magazines, but instead of sharing stories, they share new discoveries. The findings are proven with experiments, observations, and collected information. We also hear from researchers, the people making these discoveries, who send their work into journals and hope to get published. When research is published, it's taken more seriously.
Richard Smith, who used to edit a top journal, points out that the steps required for research to be published don't always make sense. Sometimes, the fact-checkers pass over studies that are really good. Other times, they miss major errors in the research and those incorrect findings still make it into the public's hands. That can cause major issues, especially when readers are relying on research journals to make decisions about what food they eat, what medicine they take, and other lifestyle choices.
Some critics of journals are worried about censorship. Censorship is when certain people or groups have control over what knowledge is shared and purposely keep some of it hidden – even if the information is 100% correct. A lot of the time, this is because the censors don't agree with the information for political or social reasons.
During the pandemic, we saw this happen with a study about vaccines that got taken back after it was shared. This made some people ask if big medical journals were hiding certain work.
Famous scientists, like Carl Heneghan and Tom Jefferson, chose to skip big journals and share their work in less-known magazines and online, because they think it's quicker and easier. But, people like John Ioannidis, a researcher, are worried this could mess up how scientific books are written. Ioannidis believes medical research should stay together so people can see the full picture, instead of having important research in places people may not know about. One former research editor, however, supports researchers sharing their own work because he thinks the checking process is too slow and often stops the researcher's ideas from coming through.
Another research editor is worried that people are starting to lose trust in medical journals and in doctors and medicine in general. She's sad that science, like many arguments during the pandemic, has become political. Ioannidis also talks about people losing trust and thinks many of the results shared in research could be wrong.
This conversation shows the fight between the old way of checking studies and the new way where anyone can access studies. While the old way is still the main way to do well in a scientist's job, the possible secrecy and hiding has made people unhappy.
he main fight is about making medical research more trustworthy and easy to get. Everyone wants to make sure that everyone else gets accurate, useful science information.

In recent years, a new debate has emerged in the scientific community about the way research is checked and published. In this article, researchers and science journal editors discuss the major problems within scientific publishing, including how these issues impact both individual scientists and the general public.
Richard Smith, the former editor of the British Medical Journal, unpacks his concerns with peer review. The peer-review process serves as the backbone of science journals' fact-checking process. Before being published in a science journal, studies are looked over by other scientists. Most of the time, peer-reviewers are picked because they are doing similar research, which can create a kind of bias especially in fields where there are only a few people doing that kind of work because it makes it very easy to know how the reviewers are and can lead to a you scratch my back I'll scratch yours environment. . This may create a bias
Smith argues that “peer review is faith not evidence based” pointing out that some previously rejected studies by peer reviewers go on to be highly regarded pieces of science. He also makes that point that errors regularly make it through the peer review.
Critics of major journals are worried about censorship. During the pandemic, we saw examples of this kind of debate, including one paper about mRNA vaccines that was pulled back after it was published.
This made some people question if big medical journals were censoring certain work. Some well-known scientists, like Carl Heneghan and Tom Jefferson, decided to skip big journals and publish their work in smaller, specialized journals and onlike platforms like Substack, because they think it's faster and less complicated. But, others like researcher John Ioannidis, worry that this could distort scientific literature. Ioannidis thinks we need to keep medical research unified and balanced.
, Smith supports self-publishing because he finds the traditional process too slow and thinks it often stifles the author's voice. He also recognizes that big journals hold much influence, especially for young researchers looking to build their careers.
Former JAMA Internal Medicine editor Rita Redberg is worried about the waning trust in medical journals and in the medical field in general. She's upset with how scientific discussions, like the mask debate during the pandemic, have become political. Ioannidis also brings up the loss of public trust, pointing to his own work that shows many published research findings may be false.
This discussion shows the conflicting views around traditional, peer-reviewed publishing and newer, open-access methods. While the old method is still the main marker of professional success, the potential secrecy and censorship has led to growing dissatisfaction. Platforms like Substack offer more control for authors and quicker access for readers, but face criticism for possibly undermining scientific literature and splitting up science.
Overall, both methods have their supporters and critics, the central point of the debate is about improving the trustworthiness and accessibility of medical research. Everybody wants to make sure the public gets accurate, effective scientific information.

Former editor of The BMJ says, “It’s interesting to me in a way that journals are still alive, because I think there’s a lot of reasons why they should be dead.”
Problems that have plagued medical journals for decades include the failure of peer review, replication crisis, ghost-writing, and the influence of Big Pharma.
In 2004, Richard Horton, editor of the Lancet wrote, “Journals have devolved into information laundering operations for the pharmaceutical industry.”
More recently, Peter Gøtzsche, one of the founding fathers of the Cochrane Collaboration said, “The medical publishing system is broken. It doesn’t ensure that solid research which goes against financial interests can get published without any major obstacles.”
Scientific publishing is now one of the most profitable businesses. Elsevier, for example, made $2.9 billion in annual revenue with a profit margin approaching 40%, rivalling that of Apple and Google.
But despite these impressive numbers, trust in medical journals has diminished, and this has only been exacerbated by the covid-19 pandemic.
Peer review fail
Former editor of The BMJ Richard Smith once famously wrote; “Peer review is faith not evidence based, but most scientists believe in it as some people believe in the Loch Ness monster.”
In a recent conversation with Richard Smith, he explained why.
“Peer review was thought to be at the heart of science – that is, who gets a grant or who gets a Nobel Prize – and I suppose it wasn’t until the 80s and 90s that somebody actually examined it – it was just sort of assumed to be a good thing,” said Smith.
“Then people began a series of experiments – there was a Cochrane review – looking at the evidence to see if peer-review was beneficial. And actually, what they found was that there was really no evidence,” he said.
Smith, who worked at The BMJ for 25 years said the peer-review process is slow, it’s expensive, and it stifles the publication of innovative ideas.
“There are lots of examples of ground-breaking work that were rejected by peer-reviewers but go on to win Nobel Prizes. Is the work crazy? Or is it truly genius? Peer review is not good at deciding that,” he said.
Peer review also fails to detect fraud. The recent Surgisphere scandal is a case in point.
Lancet and New England Journal of Medicine were forced to retract studies after researchers reported a link between treatment with hydroxychloroquine and increased death of hospitalised covid patients.
Glaring discrepancies were found in the database underpinning the studies, but were not detected in the peer-review process.
“If researchers say there were 200 patients in the study, then you assume there were. But we have increasing evidence that that’s not the case – there are a lot of zombie trials that never happened or have been manipulated in some way,” said Smith.
“So, in a nutshell, we have lots and lots of evidence of the downside of peer review and really no convincing evidence of its upside,” he added.
Rita Redberg, a cardiologist at the University of California San Francisco, who recently stepped down after 14 years as chief editor of JAMA Internal Medicine, concedes that peer-review is “not perfect”.
“You always assume that what the authors are telling you is true. The process depends on the honesty of the authors, and yes, people can be dishonest. But we’re doctors, we’re not investigators with the resources of the FBI. Of course, when any potential dishonesty comes to our attention, we will investigate,” said Redberg.
“It has its problems, but what’s the alternative? No peer-review? In general, I think peer review is much better than a system without peer review,” added Redberg.
Politicisation of journals
During the pandemic, some journal editors became increasingly politicised.
Editors at the New England Journal of Medicine, for example, took the rare step of writing an editorial in 2020, urging American voters to oust the sitting President. It was a controversial move.
John Ioannidis, Professor of Medicine at Stanford University, and the most cited scientist in the world, said he is not in favour of the politicisation of medical journals.
“The message it sends is that scientific journals are just another arm of the political propaganda machine,” said Ioannidis.
“That’s not to say that scientific journals shouldn’t take stances on important issues that are decided by politicians like climate change, regulation of industry, and environmental pollution. I just think the editorials were very poor choices and not for the pages of the journals,” he said.
Ioannidis is not convinced that these political statements swayed anyone to cross the political aisle, and thinks the editorials should be retracted.
“To be honest, the editors who made these statements should retract their own editorials on these political issues. Editors can keep their political orientation and still cover all the big important medical issues,” he added.
Emergence of pre-prints
Pre-prints are non-peer-reviewed articles posted on servers such as medRxiv and bioRxiv, that allow thousands of people to view the research. Many see this as a double-edged sword.
It enables faster data sharing in an emergency and quick feedback, but it also opens the door to sloppy science that can be widely disseminated by the public and the media.
Redberg’s personal view is that pre-prints, which have not undergone peer-review, are potentially harmful.
“I think there’s a danger of putting out information that’s not accurate. For approval of drugs and devices, it’s worth taking the time to get things right. I feel much more confident that you’re going to get it right if it’s undergone peer review,” said Redberg.
“I think it started with very good intentions – people sharing their work and getting comments – but the articles stay up there even after they’re published in journals, and having an older, different–and possibly inaccurate–version remaining in the public sphere may inadvertently disseminate incorrect information,” added Redberg.
Ioannidis, on the other hand, says he is in favour of pre-prints because “they offer more transparency in the system, and they allow for some earlier dissemination of work,”.
But he warned it can be a battlefield citing experiences where some of his pre-prints would receive more than 1000 peer reviews within a day of release.
“A few were very, very helpful. Hundreds of them were just abuse. It was a very traumatic experience. If you separate what is the good contribution versus the abuse, then I think that they’re useful,” said Ioannidis.
Smith argues that pre-prints actually prove his point about the failure of peer-review. “If you look at what eventually appears in journals, it’s usually very similar to the original pre-print. So, it’s evidence that peer review has not made much of a difference,” said Smith.
“What I argue is that the peer review should not be three or four selected people looking at something before it’s published, but where the ideas are available to everybody. That’s the real peer review,” he said.
Scientific censorship
Publishing articles in medical journals during the pandemic, especially research that was critical of vaccine safety, was sometimes censored or retracted for no good reason.
For example, a peer-reviewed paper linking the mRNA vaccines with myocarditis, authored by doctors Jessica Rose and Peter McCullough, was suddenly withdrawn with insufficient cause.
Some high-profile scientists have decided that the time burden and logistical intensity of publishing in the major medical journals is simply not worth it.
Carl Heneghan and Tom Jefferson, for example, two of the most reputable researchers in the world, say they’ll only publish in specialised journals that have peer-reviewers with the right expertise.
Otherwise, the bulk of their work is published on the writing platform, Substack (Trust The Evidence).
“I do worry about that,” says Ioannidis. “We need the voices of people like Carl Heneghan and Tom Jefferson and others in the mix. I suppose if they’ve been thwarted, then there must be some venue where that missing part can appear, and perhaps Substack caters to that need.”
“I do wish that we get them back into the traditional type of medical journals though. If the classical literature is missing a very key perspective like theirs, then the distortion becomes bigger,” he said.
“It makes it more difficult to balance the literature when knowledgeable, critical voices are missing. I know I may sound like I’m willing to stick to that sinking ship. But I would prefer to not fragment science into medical journals, and Substack and who knows where else,” added Ioannidis.
Smith on the other hand, is more enthusiastic about self-publishing.
“I’m in favour of getting it out there. Let the world decide. It makes a lot of sense to me,” says Smith citing his own challenges with publishing in medical journals.
“Recently, I submitted a piece to the Lancet – a book review – and there was the hassle of all the forms you have to fill in, all the comments from the editors, which I mean – maybe it’s arrogance on my part – but didn’t seem to make things much better,” said Smith in a perturbed tone.
“You’ve got a particular voice, and they disrupt it to some extent. So, it ends up much messier. Doesn’t feel to me like there’s a lot of value added in that process,” he said.
Smith says self-publishing is more of a problem if you are a junior researcher and want to rise in the academic arena.
“You need to publish in these journals because that’s how you’re judged. If you’ve published in the New England Journal of Medicine, it’s assumed to be a very significant piece of research. I mean, it’s completely unscientific to use the place you publish as a surrogate for the value of the research, but that’s what continues to happen,” said Smith.
Diminished trust
Redberg says it’s not just medical journals that lost trust.
“I think people’s trust in medicine and public health diminished in general in the last few years. The sad part to me is that science became political – whether you wore a mask or not became a political statement – It’s not a political question. It’s a scientific question,” said Redberg.
Ioannidis who famously authored the paper, “Why Most Published Research Findings Are False” said, “I think that we are losing…well, we have already lost the trust of a major part of the population.”
“Covid created a lot of extra stress on the system. People wanted to publish papers very quickly, by now it’s almost a million papers. We’ve looked at the covid literature and most of it was very sloppy, corners were cut, probably worse than usual,” said Ioannidis.
“The frontier of science is broken at the moment. If we do not acknowledge that we have a problem – and make no mistake – we have a very serious problem, then it will be difficult to defend against conspiracy theories or against people who just want to make money by spreading misinformation or disinformation,” he added.
So, are medical journals dead?
“I don’t think medical journals are dead, no. I feel like they’re busier and more important than ever, because there’s so much innovation and I think that disseminating it through a high-quality, peer-review process is the best way to go,” said Redberg.
Ioannidis is quick to acknowledge there is a problem with medical journals. “They are very sick, and they suffer from all sorts of diseases, but I just don’t want to say that I’m giving up on them. They need to transform. I hope that they get better. But I don’t want to proclaim them dead yet.”
Smith agrees that there’s a role for medical journals, but he seems less invested.
“It’s interesting to me in a way that journals are still alive, because I think there’s a lot of reasons why they should be dead,” said Smith.

Obviously a massive problem that science has become a business…
The idea of peer review has good intentions, but it is only as good as the reviewer is honest and has the resources to sift through the bullshit.
Ultimately, I think, the solution starts with education and a culture change. That is why the Broken Science Initiative is so powerful. If those who lead the way have a deeper understanding of what science is, and really care about the Truth, the process fixes itself.
Like Greg says – Any man, but not every man, will learn this.
…My hope is that enough learn to hold a dim light at the end of the dark mainstream tunnel.
Thank you for the article Maryanne. One important thing to mention regarding journals is the paywall that keeps researchers away from information. Science isn’t being shared openly. Perhaps, the model could quickly fall apart with a peer reviewed “wiki-medical journal”.
