Acceleration of the arms race between fraudsters and honest researchers

I was recently asked to review a paper that piqued my curiosity. From the abstract it sounded as if it was a secondary analysis of a dataset that I had deposited in a repository. But the described data didn't quite match what was in the repository. As I usually do, I said I'd only review it if data and code were available. The authors complied: I was pointed at the repository where my data were…

How paper mills go straight (without going clean): a shift to dual-use services

Guest post by Matt Spick Photo: Parsadanov/Shutterstock.com From relative obscurity, paper mills have recently moved into the spotlight of academic attention. These organisations - which sell manuscripts or citations to authors to enhance scholarly metrics - are growing so rapidly that many fields are being overwhelmed. The overall proportion of paper mill outputs was estimated at 1.5–2% of all…

That fireside chat with Jay Bhattacharya: a view from across the pond

On Friday I attended (virtually) a workshop organised by the National Academies of Science, Engineering and Medicine on Enhancing Scientific Integrity: Progress and Opportunities in the Social and Behavioral Sciences . On social media, the workshop attracted a lot of critical commentary, mainly because it included a "fireside chat" with Jay Bhattacharya, who is currently the Director of the…

Update on Wellcome LEAP's $50 million program on autism and the microbiome

Exactly five months ago, I blogged about a program entitled Foundations of a Resilient Microbiome (FORM) that Wellcome LEAP was funding to the tune of $50 million. I had major reservations about the foundations of the research program, which seemed based on flaky research. By coincidence, the 2025 funding call for FORM came out a couple of weeks before publication of a review that I co-authored…

Bishopblog catalogue (updated 12 Mar 2026)

Source: http://www.weblogcartoons.com/2008/11/23/ideas/ Those of you who follow this blog may have noticed a lack of thematic coherence. I write about whatever is exercising my mind at the time, which can range from technical aspects of statistics to the design of bathroom taps. I decided it might be helpful to introduce a bit of order into this chaotic melange, so here is a catalogue of posts by…

Guest post: Stealth corrections are still a threat to scientific integrity

Authors René Aquarius , Floris Schoeters , Alex Glynn , Guillaume Cabanac An update on stealth corrections Last year, we published an article describing stealth corrections , a phenomenon in which a publisher makes at least one post-publication change to a scientific article, without providing a correction note or any other indicator that the publication was temporarily or permanently altered.…

An analysis of PubPeer comments on highly-cited retracted articles

PubPeer is sometimes discussed as if it is some kind of cesspit where people smear honest scientists with specious allegations of fraud. I'm always taken aback when I hear this, since it is totally at odds with my experience. When I conducted an analysis of PubPeer comments concerning papers from UK universities published over a two-year period, I found that all 345 of them conformed to PubPeer's…

The dangers of using bibliometrics with polluted data

This week I attended a Webinar organised by Clarivate on the topic of “ Eugene Garfield Centenary Celebration: Past, Present and Future of Scientometrics ”. This covered the early history of the late Eugene Garfield’s work as well as current developments and future trends. The historical sessions were fascinating, describing the remarkable innovations that Garfield made in his quest to understand…

The inner workings of a paper mill:

My Norxin sting operation Guest post by Csaba Szabo Chair of Pharmacology, University of Fribourg, Switzerland After the limited success of my prior sting operation , I have decided to do a second one. I cannot follow up on all the scummy and fishy invitations that I receive on an almost daily basis, but this one from Norxin's "Sherry" (obviously, not a real name – did you notice, by the way, how…
