Curbing the Ramifications of Authorship Abuse in Science

Research performance is often measured using bibliometric indicators, such as publication count, total citations, and $h$-index. These metrics influence career advancements, salary adjustments, administrative opportunities, funding prospects, and professional recognition. However, the reliance on these metrics has also made them targets for manipulation, misuse, and abuse. One primary ethical concern is authorship abuse, which includes paid, ornamental, exploitative, and cartel authorships. These practices are prevalent because they artificially enhance multiple bibliometric indicators all at once. Our study confirms a significant rise in the mean and median number of authors per publication across multiple disciplines over the last 34 years. While it is important to identify the cases of authorship abuse, a thorough investigation of every paper proves impractical. In this study, we propose a credit allocation scheme based on the reciprocals of the Fibonacci numbers, designed to adjust credit for individual contributions while systematically reducing credit for potential authorship abuse. The proposed scheme aligns with rigorous authorship guidelines from scientific associations, which mandate significant contributions across most phases of a study, while accommodating more lenient guidelines from scientific publishers, which recognize authorship for minimal contributions. We recalibrate the traditional bibliometric indicators to emphasize author contribution rather than participation in publications. Additionally, we propose a new indicator, $T^{\prime}$-index, to assess researchers' leading and contributing roles in their publications. Our proposed credit allocation scheme mitigates the effects of authorship abuse and promotes a more ethical scientific ecosystem.
