How Universities Evolved into Hubs for Academic Slop and Fraud
For universities, it seems that challenges never cease. While media headlines often highlight the struggles of graduates with mounting, unrepayable loans, a more insidious crisis is brewing at the heart of higher education. Concerns are intensifying over what many consider the core function of intellectually robust universities: the research they publish. Academics disseminate their work through specialist journals, which ideally only accept papers after rigorous peer review to ensure quality. However, the past decade has witnessed an explosive growth in both the number of journals and the volume of published papers. In 2016, an estimated 1.9 million academic articles were released globally across all disciplines. Today, that figure has skyrocketed to over 5 million and continues to climb.
The Proliferation of Fake Papers and Academic Slop
Unless one's expertise is extremely narrow—such as in Hittite grammar—it is impossible to read every relevant piece of research, and in some fields, not even a fraction. Fortunately, much of this output holds little value, rendering it inconsequential whether it is read or not. Academics typically judge a paper's worth by its citations in other publications. Alarmingly, in most disciplines, well over half of all published papers receive zero citations, representing a tremendous waste of effort. This scenario is akin to a Soviet factory meeting its Five Year Plan quota by producing only right-footed shoes—huge quantities are made, but they are essentially worthless.
Despite this, academics are acting rationally as individuals by continuing to produce such work. They face immense pressure to publish papers, as promotions and job security heavily depend on this metric. Worryingly, evidence is mounting that the system is being gamed on an escalating scale. In fact, the situation is far more dire: the number of purely faked papers is rising at a much faster rate than that of genuine ones.
Universities Have Become a Marketplace for Fraud
Luis Amaral, a leading network analysis specialist at Northwestern University in America, and his team have recently published a paper in the Proceedings of the National Academy of Sciences that raises major concerns. Using advanced mathematical techniques, they identified that faked papers are being generated by so-called paper mills. Citations of these papers in journals are being systematically manipulated, and scientific fraud extends beyond fake paper production to include brokerage roles within a widespread network of editors and authors who collaborate to bypass traditional peer-review standards.
Amaral and his colleagues have uncovered organizations selling "contract cheating services," which, for example, pay journal editors to accept papers and anticipate defensive measures taken by reputable journals to identify bogus results. They conclude by warning of the dangers posed by large-scale fraudulent science, especially given the increasing use of large language models to encapsulate scientific knowledge. These models currently cannot distinguish high-quality science from poor-quality or fake science.
To economists, this development is unsurprising. A market has emerged where universities have created performance metrics focused on publication counts and citation numbers. Incentives to game the system exist, and people are responding to them. Amaral argues that in some fields, the scientific literature is already "irreparably damaged." Both universities and public grant-giving bodies in research must urgently review these metrics before the problem spirals completely out of control.
