Group 1 - A gray industry chain has emerged in China, offering "invisible retraction" services to delete published papers from databases for fees ranging from hundreds to tens of thousands of yuan [2] - A study led by Professor Adrian Barnett from Queensland University of Technology found that over 250,000 cancer research papers published between 1999 and 2024 are suspected to be products of "paper mills," with over 170,000 from Chinese institutions, accounting for 36% of China's total cancer paper output during that period [2][3] Group 2 - The prevalence of low-quality papers, referred to as "water papers," is attributed to the "four only" evaluation system in academia, which emphasizes only papers, titles, degrees, and awards, leading to a focus on quantity over quality [3][4] - The rise of generative artificial intelligence has made it easier to produce "water papers," raising concerns about the dilution of research quality and the urgency to address this issue [4] - The Chinese government has recognized the problem and initiated reforms to the talent evaluation system, aiming to shift focus from the "four only" approach to a system that values innovation, capability, and contribution [4][5]

Core Viewpoint - The article highlights the urgent need to reform the evaluation system for scientific talent in order to combat the proliferation of low-quality academic papers, often referred to as "water papers," and to ensure that genuine scientific contributions are recognized and valued [3][4]. Group 1: Academic Integrity Issues - A gray industry has emerged around "no-trace retraction" services in China, where intermediaries charge substantial fees to remove published papers from databases without leaving a trace, often involving fraudulent practices [2][3]. - A study led by Professor Adrian Barnett from Queensland University of Technology found that over 250,000 cancer research papers published between 1999 and 2024 are suspected to be products of "paper mills," with over 170,000 of these originating from Chinese institutions, accounting for approximately 36% of China's total cancer paper output during that period [2][3]. Group 2: Impact of "Water Papers" - The prevalence of "water papers" not only wastes research resources and undermines academic credibility but also hinders genuine scientific progress, necessitating immediate action to curb this trend [4]. - The rise of generative artificial intelligence has made it easier to produce low-quality, homogeneous papers, further diluting the overall quality of scientific literature [4]. Group 3: Reform Initiatives - The Chinese government has recognized the need for reform, with multiple initiatives launched since 2016 aimed at innovating the talent evaluation mechanism to focus on moral character, ability, and actual contributions rather than solely on publications, titles, degrees, and awards [4][5]. - The "breaking the four 'onlys'" initiative aims to liberate research institutions and personnel from rigid evaluation systems, allowing them to focus on addressing real scientific challenges and making meaningful contributions [5]. - Progress has been made in establishing new evaluation standards, including category-based assessments and third-party evaluations, which reflect the true innovative value and contributions of researchers [5].
