Sholto David and his work exposes flaws in publishing poor research.
Highlights:
- The scientific publishing system has structural flaws that allow manipulated or careless research to be published without real oversight.
- Dr. Sholto David exposes fraud and errors, mainly through tools like PubPeer, plagiarism detectors, and image-tracking software.
- Common red flags include duplicated images, mathematical inconsistencies, and implausible clinical trial data.
- The academic system’s pressure to publish and be cited fuels misconduct, prioritizing productivity over truth.
- True integrity in science requires cultural and structural change, shifting focus from quantity of publications to accuracy and transparency.
Several academics from prestigious research institutions, including some directors, have been embroiled in scandals after it was discovered that they had published scientific papers with manipulated information. Images used in certain studies turned out to be duplicates, creating a domino effect. Multiple articles have had to be retracted, exposing weaknesses in the scientific publishing system. Most concerning is that there are thousands of similar frauds.
The person who uncovered this was Dr. Sholto David, selected as one of Time magazine’s 100 most influential people in health for his work as a watchdog of scientific publications. Trained in Biochemistry at the University of York in the United Kingdom, David went on to earn a PhD in Cellular and Molecular Biology at Newcastle University. He finished in 2019 and officially received the title in 2020. Since then, he has worked in industry at a company dedicated to cell therapies and tissue engineering. “I focus on measurement and on developing and running biological assays,” he explains.
With acupuncture, for example, you basically take a needle, stick it into the skin, and supposedly it cures all kinds of diseases.

The doctor admits he has always been curious about what he calls “fringe ideas,” such as different forms of alternative medicine, including herbalism and acupuncture, mainly because they lack scientific evidence and are often presented as miracle cures. “With acupuncture, for example, you basically take a needle, stick it into the skin, and supposedly it cures all kinds of diseases,” he says. Herbalism, on the other hand, occupies a more ambiguous place. While there are indeed active compounds with real pharmacological value, the false belief persists that there are herbal remedies for every illness. “If you ask someone into herbalism, they’ll tell you they can treat everything.” That gray area has always attracted his attention because he wants to expose the falsity of such claims, as well as many others presented as scientific without truly being so.
These “fringe ideas” or manipulated information can even find their way into scientific journals that are supposed to be backed by peer review. In theory, peer review should guarantee the quality and relevance of each study before publication, but when it fails, the consequences can be enormous. Dr. David has even shown that in practice this mechanism is vulnerable to abuse, since dubious studies, whether due to simple mistakes or outright fraud, sometimes make it through and get published. That was what motivated him, because the scientific community must call out errors. It becomes a kind of continuous peer review, happening after papers are already published.
Almost all my comments are critical of the work.

“Until you sit down and say, ‘I’m going to look for an error,’ you might simply not see them,” says David. On PubPeer, a platform where scientists can comment on already published articles, he found a community of critics who extend peer review beyond the pre-publication stage. There, discussions have led to retractions and formal accusations of fraud. He also relies on digital tools like plagiarism detectors or Image Twin, software that tracks images in papers to spot duplicates. Errors, he says, can be seen once you learn to analyze from a different perspective. Over time, he has commented on more than five thousand scientific papers. “Almost all my comments are critical of the work,” he admits.
He began publishing on PubPeer anonymously. “Not for any particular reason,” he explains. It’s just easier to get an anonymous account if you don’t have a university email, though it also gave him a layer of protection from authors who might retaliate or take offense. Today, however, most of his interventions carry his real name. While he has received several legal threats, none have ever seemed imminent or credible. “People often make legal threats without much basis, so I’ve never really felt at particular risk.”
I’m pretty direct. I think being overly polite doesn’t get much response

“I really enjoy debating with authors,” he says. He doesn’t care about his reputation. “I get satisfaction from finding mistakes and don’t worry too much about the consequences.” He has even made YouTube videos about research misconduct and, when he finds something noteworthy, writes for Leonid Schneider’s blog forbetterscience.com. “I’m pretty direct. I think being overly polite doesn’t get much response.” What is truly alarming, he warns, is that in preclinical research the risk is that human clinical trials may begin with drugs that may not actually be effective. In other words, people could be exposed to interventions that will never work. At other times, errors are amplified because other authors cite the flawed research in their own publications, since publishing and being cited are two of the biggest priorities in academia. That pressure may explain why such fraud occurs. “There’s value in published papers because they help secure grants and career advancement, but almost no one worries about checking whether those papers are true or not,” he warns. “I think the problems are more structural and that the solution won’t come from individuals reviewing articles, but from a broader shift in perspective,” he adds.
What often happens is that the same image is used twice, the exact same one.

Among the most common red flags in suspicious scientific papers are duplicated images. They may be photos that, with a simple rotation, reflection, or flip, are passed off as different data, and according to Sholto they’re more frequent than you’d think. For instance, in experiments showing cells exposed to different concentrations of a chemical, each image should in theory reflect a change. But “what often happens is that the same image is used twice, the exact same one.” Sometimes, images even appear copied from unrelated studies published by other authors.
The red flags, however, aren’t limited to images. There are also mathematical contradictions that reveal a lack of rigor. For example, some clinical trials claim to recruit 50 patients, “but later they write that 26 were women and 27 were men.” That’s 53 patients. Finally, other papers may describe implausible timelines or patient recruitment processes that are practically impossible.
I tend to think that, when it comes to scientific literature, we should be aiming for 100% accuracy.
Sholto David
Although David is most interested in fraud, papers where the deception is deliberate, in his work he also encounters minor errors, usually due to carelessness rather than bad faith. But even those, to him, expose a vulnerable system. He is firm in his belief that science, more than any other field, should always aspire to perfection. “I tend to think that, when it comes to scientific literature, we should be aiming for 100% accuracy,” he says. “I have no illusion that I’m going to fix science with this,” he admits. Even so, his work has already led to more than 200 retractions and, most importantly, has exposed structural flaws, reminding us that science requires constant scrutiny. In the end, it’s about transforming the culture and structures of science so that integrity is ensured, putting transparency and rigor above productivity. As he himself acknowledges, “today, the value of a scientific paper doesn’t really lie in whether it’s correct or not, but in whether people manage to publish it.”
