Quantitative bibliometric indicators are misused for research assessments. This review details gaming practices like authorship and citation manipulation, suggesting better metrics can detect and deter such issues.
Area of Science:
- Bibliometrics and scientometrics
- Research assessment
- Scientific publishing
Background:
- Quantitative bibliometric indicators are extensively used in research assessment and career advancement.
- The "publish or perish" and "get cited or perish" culture incentivizes gaming of these metrics.
- Gaming practices can undermine the integrity of scientific evaluations.
Purpose of the Study:
- To review and categorize various gaming practices associated with quantitative bibliometric indicators.
- To discuss the implications of these gaming tactics on scientific careers and evaluations.
- To propose the use of improved quantitative metrics for detecting and contextualizing gaming.
Main Methods:
- Comprehensive literature review of gaming practices in bibliometrics.
- Categorization of gaming tactics into authorship-based, citation-based, editorial-based, and journal-based.
- Discussion of specific examples such as gift authorship, salami slicing, citation farms, and paper mills.
Main Results:
- Identified numerous gaming practices, including authorship manipulation (gift authorship, salami slicing), citation manipulation (self-citations, citation farms), and journal-based manipulation (impact factor gaming).
- Highlighted the role of paper mills and spurious publications in inflating metrics.
- Emphasized that quantitative metrics and analyses can aid in detecting and contextualizing these gaming behaviors.
Conclusions:
- Quantitative bibliometric indicators are susceptible to widespread gaming, impacting research assessments and careers.
- Detection and perspective on gaming practices can be enhanced through rigorous, transparent quantitative metrics.
- Incorporating indicators of both best and poor research practices into metrics can strengthen scientific evaluations.
