Science journalism can expose bad science and trigger real-world change, new study reveals

August 24, 2026 · 10 min

Max Rivera & Clara Bennett

Science journalism now functions as a second peer-review layer: fraud-related retractions are growing at 13.3% annually, 2023 saw over 10,000 retractions in a single year, and historical cases like cold fusion and the vaccine-autism fraud were exposed by reporters, not scientists — yet the system was never designed this way.

A study published in *Media and Communication* by researchers Michele Catanzaro and Luiz Peres-Neto (Autonomous University of Barcelona) examines "watchdog science journalism"—the practice whereby journalists investigate malpractice, fraud, and corporate manipulation in scientific research.

About this episode

The system catching industrialized scientific fraud is, in many cases, a reporter checking a WhatsApp notification. That's not a metaphor — it's a description of how paper mill investigations actually work in 2026. This episode starts with a Guardian investigation documenting more than twenty unsolicited offers to sell authorship on fabricated papers, all received in a single day, all openly advertised on messaging apps. From there it traces why peer review was never built to catch this: it assumed honest actors, it isn't adversarial by design, and its retraction lag spans a 40-fold range depending on who's publishing. Retraction Watch data shows fraud-related retractions growing at 13.3% annually since 1975 — a rate that doubles the problem every five years, with 2023 setting a new record above 10,000. The episode draws on formal research — work by Michele Catanzaro, Luiz Peres-Neto, and Alice Fleerackers — to define what watchdog science journalism actually is and what it requires to function: adequate staffing, editorial independence, and reporters who treat scrutiny as the job, not a side effect of it. It also sits honestly with the failure modes: coverage decisions shaped by what's explainable rather than what's important, trust asymmetries between scientists and journalists, and the coming problem of AI systems that misrepresent research scope in ways that won't register as fraud. About ten minutes. Worth it.

Frequently asked

How many scientific papers were retracted in 2023?

Scientific paper retractions exceeded 10,000 in a single year for the first time in 2023, according to Retraction Watch data. Fraud-related retractions are growing at 13.3% annually — a rate that roughly doubles the problem every five years, meaning today's count could quadruple within a decade.

What are paper mills in academic publishing?

Paper mills are organized commercial operations that sell authorship on fabricated research papers. They advertise openly on platforms like Telegram, WhatsApp, and Facebook groups. Demand is driven by publish-or-perish incentives, where academic careers and grant funding depend on publication volume rather than research quality.

What is watchdog science journalism?

Watchdog science journalism is a formally defined practice, named by researchers Michele Catanzaro and Luiz Peres-Neto at the Autonomous University of Barcelona, in which reporters actively scrutinize funding sources, ethical considerations, and reproducibility — rather than simply covering scientific findings. It functions as a post-publication accountability layer distinct from peer review.

Do science journalists actually uncover scientific fraud?

Yes. Historical cases including cold fusion in 1989 and the vaccine-autism fraud in 1998 were exposed by journalists, not flagged internally by scientists. Alice Fleerackers documented this pattern through 21 semi-structured interviews with working science journalists, published in Journalism Practice, confirming that probing misconduct is a deliberate, not accidental, part of the job.

Why does peer review fail to catch fabricated research?

Traditional peer review was not designed adversarially — it assumes honest actors and reviews only what authors submit. Retraction Watch data shows the median lag between publication and retraction spans a 40-fold range across publishers, meaning fraudulent papers can circulate for years, accumulating citations and shaping clinical practice before any correction is issued.

Clara Bennett: Before we get into anything else — did you see the Guardian piece from August 2026?

Max Rivera: The paper mills thing? Yeah, I did, and I — wait, walk me through it, because I want to make sure I'm not overstating what actually happened.

Clara Bennett: One journalist, tracking these networks, documented over twenty unsolicited solicitations in a single 24-hour stretch — Telegram, WhatsApp, Facebook groups — each one offering to sell authorship on a fabricated research paper. Not hacking. Not back-channel academic politics. Openly advertised, like spam.

Max Rivera: So people are — I mean, the messaging app is just the storefront. They're selling fake papers like someone sells refurbished laptops in a Facebook group.

Clara Bennett: Exactly that. Paper mills are organized commercial operations. The product is fraudulent scientific credibility. And the demand engine is publish-or-perish — careers and grant funding contingent on publication volume.

Max Rivera: So the incentive structure basically created a black market and nobody closed the kitchen.

Clara Bennett: In practice, peer review was never built for this. It's a health inspector who only visits when scheduled. These paper mills are cooking at three in the morning, no inspection, no oversight.

Max Rivera: And a journalist had to be the one to walk into that kitchen.

Clara Bennett: And what the journalist found wasn't just the paper mills — it was the scale underneath them. Retraction Watch has been tracking this since 1975, and the fraud-related retractions are growing at 13.3% annually. That's not drift. That doubles the problem roughly every five years.

Max Rivera: Wait — doubles every five years? So whatever we're counting today, in a decade it's four times that?

Clara Bennett: In principle, yes. And 2023 already crossed 10,000 retractions in a single year. New record.

Max Rivera: Ten thousand. In one year. I mean — okay, I want to steelman the other read here, because the PMC analysis actually flags this: maybe rising retractions mean the system is catching more? Like, heightened scrutiny, not more fraud necessarily?

Clara Bennett: That framing is real. Detection improving is not the same as fraud shrinking. But the retraction lag complicates both versions of that story.

Max Rivera: The lag — yeah, this is actually the part that — wait, this is what keeps me up, honestly. A paper gets published. It circulates. Gets cited by three other papers. Maybe it's shaping a clinical protocol somewhere. And then, what, two years later someone pulls it?

Clara Bennett: Retraction Watch data shows the median lag spans a 40-fold range depending on the publisher. Forty-fold. Some papers get caught in months. Others circulate for years, cited the whole time.

Max Rivera: A 40-fold range — so the retraction is kind of a fiction of cleanup, right? The bad science is already embedded in the literature. Other studies built on it. The correction runs in a journal nobody outside the field reads.

Clara Bennett: That's the structural problem. Peer review was never adversarial by design — it assumed honest actors. So now the question is whether post-publication review, including journalism, can actually close that gap before the damage compounds.

Max Rivera: But that gap — post-publication, journalism filling it — that's not a designed handoff. That's an accident. And the truth is: there are historical cases where journalism didn't just help. It was the whole mechanism. Cold fusion, 1989. The vaccine-autism fraud, 1998. Those weren't caught internally. Scientists didn't flag them. Reporters did.

Clara Bennett: And that's exactly what Michele Catanzaro and Luiz Peres-Neto at the Autonomous University of Barcelona formalized. Their study in Media and Communication defines this as watchdog science journalism — not just covering findings, but actively scrutinizing funding sources, ethical considerations, reproducibility. It's a distinct practice with a name now.

Max Rivera: Wait — so there's a formal definition? Like, someone drew the line between science reporter and watchdog?

Clara Bennett: Catanzaro and Peres-Neto did, yes. And Alice Fleerackers built on it empirically — 21 semi-structured interviews with working science journalists, published in Journalism Practice, documenting that these reporters are actively probing misconduct. Not accidentally. Deliberately.

Max Rivera: Twenty-one interviews — I mean, that's qualitative, not a census. But what it tells you is there are journalists who see this as their actual job, not a side effect of covering a story.

Clara Bennett: Right — and the Fleerackers study links directly to post-publication peer review as the layer journalism helps constitute. That's the framing: journalists aren't replacing peer review, they're forming a second accountability layer after publication. Citizens, by the way, explicitly endorse this — particularly in health and climate reporting.

Max Rivera: So here's what's weird to me — picture a researcher somewhere, say a cardiologist in Lyon, whose dataset is quietly fabricated. Peer reviewers read the methods section and it looks clean. Then a journalist, not a cardiologist, reads the funding disclosure and finds a pharmaceutical contract that wasn't disclosed. That's — the journalist caught what the expert missed.

Clara Bennett: Because peer review wasn't designed adversarially. Watchdog journalism is. That's the structural difference Catanzaro and Peres-Neto are pointing at. And honestly — the part that comes later makes this whole picture more complicated, because the same newsrooms doing this work are making story decisions based on feasibility, not public importance.

Max Rivera: Yeah — and that's, I mean, that's the version of this story that should make everyone a little uncomfortable.

Clara Bennett: And the Fleerackers study is where that gets uncomfortable in a very specific way. It's not just that newsrooms are stretched — it's that when resources are thin, story feasibility starts outweighing public importance in coverage decisions. That's documented. Not assumed.

Max Rivera: Wait — say that again. Feasibility over importance? Like, a scientist commits fraud in, I don't know, a hard-to-explain corner of epidemiology, and a reporter just... doesn't chase it because the story won't land with a general audience?

Clara Bennett: That's exactly the mechanism. And the editorial independence piece matters here too — Fleerackers documents adequate staffing and editorial protection as prerequisites for watchdog function. Remove either one, and the scrutiny collapses to whatever is explainable in 800 words.

Max Rivera: So the fraud that's hardest to understand is also the fraud most likely to go uncovered. That's — I mean, that's almost a perfect inversion of what you'd want from a quality-control layer.

Clara Bennett: And it creates a trust asymmetry that's worth naming. Public trust in science rests on competence and integrity. Trust in science journalism rests on selection credibility — did they pick the right story — and accuracy. Those are different contracts. So when an under-resourced reporter does challenge a well-funded lab, the public isn't sure whose credibility to weight.

Max Rivera: Right — but the same dynamic runs in reverse too. A journalist covers a promising finding, it spreads, and then the retraction comes two years later and nobody sees it. Journalism is cure and disease at the same time. That's not a metaphor — that's a logistics failure.

Clara Bennett: Now add AI into that. If you solve the resource problem by using an AI system as the first interpreter of biomedical research — summarizing trial results, flagging significance — you've introduced generalization bias. These systems over-extend findings beyond their actual scope. And no existing watchdog structure, not peer review, not journalism, was built to audit that.

Max Rivera: So the watchdog needs a watchdog and nobody built one.

Clara Bennett: In practice — no. The accountability structures we have were designed for human actors making legible decisions. An AI flattening a clinical trial's scope limitations into a shareable summary doesn't look like fraud. It looks like simplification. And that's the part that won't show up in Retraction Watch.

Max Rivera: And that's — I mean, that's the reality. Nobody voted for this. Nobody sat down and said: journalists will be the fourth pillar of scientific integrity. It just... became true. The Guardian investigation, the Retraction Watch numbers, cold fusion, the vaccine-autism case — all of it accumulated into a job that journalism is doing without ever having been hired for it.

Clara Bennett: The paper mill messages are still coming in. Someone is reading them. It's just sitting with me — the system catching industrialized fraud is a reporter checking a WhatsApp notification.

Max Rivera: Yeah. And I don't know if that's enough. I genuinely don't. The question isn't whether watchdog science journalism is doing something real — it is. It's whether anyone actually understands that this is the job it's doing now. Structurally fragile, never designed for this scale, and holding anyway.
