Sciency Words: Academic Paper Mills

Hello, friends!  Welcome back to Sciency Words, a special series about those weird and wacky words scientists use.  In this week’s episode of Sciency Words, we’re talking about:


A paper mill is a factory that produces paper.  It’s a perfectly legitimate business.  An academic paper mill is a business that, in an almost factory-like manner, cranks out fraudulent academic papers.

This term came up in my ongoing research about research.  Academic paper mills are a growing concern in the scientific community.  An extraordinary number of these paper mill papers have gone through the peer review process and been published in highly respected journals.

Distressingly, even when the origins of a paper mill paper are exposed, publishers do not always make that clear.  As this article from Nature explains:

Publishers almost never explicitly declare on retraction notices that a particular study is fraudulent or was created by a company to order, because it is difficult to prove.

Even so, that same article from Nature says that at least 370 published papers have been retracted since January of 2020 due to their suspected paper mill origins.  Another 45 have been flagged with “expressions of concern” by the journals that published them.  And since academic journals started cracking down on paper mill papers, it seems that some researchers have decided to voluntarily retract their own research “without stating the reason for retraction.”

Based on what I read in that Nature article, as well as in other articles like this one from Chemistry World, I get the sense that this is a bigger problem in some scientific fields than it is in others.  Fields like biomedical science, computer science, and engineering seem to be getting paper milled the hardest—in other words, fields where there’s the most money to be made and where researchers are under the most pressure to rack up publication credits.

For my own purposes as a science fiction writer who wants to do his research, I read a fair number of academic papers: mostly papers on astrobiology and planetary science.  I doubt I have to worry much about paper mill papers in those fields.  There are, however, other red flags I know to look out for.
