The impact factor, a scientometric indicator used in German universities, has significant limitations. Its uncritical use is unscientific and disadvantages non-English publications and clinical disciplines.

Area of Science:

  • Bibliometrics
  • Scientometrics
  • Scientific Publishing

Context:

  • The increasing demand for performance indicators in academia for fund allocation and appointments.
  • The widespread, yet problematic, adoption of the journal impact factor (IF) as a primary scientometric tool in German universities.

Purpose:

  • To critically evaluate the limitations and systematic problems associated with the journal impact factor.
  • To highlight the unscientific nature of its uncritical application in academic evaluation.

Summary:

  • The journal impact factor (IF) is calculated by the Institute for Scientific Information (ISI) and is influenced by self-citations and citation groups.
  • It disadvantages non-English journals and clinical disciplines, favoring basic sciences and interdisciplinary fields.

  • The short 2-year calculation period favors rapidly disseminated publications, not necessarily the most impactful or cited journals.

    • Impact:

    • The IF's limitations lead to the disregard of specialist knowledge in favor of a pseudo-objective metric.
    • Correction factors are needed for different disciplines, and faculties should agree on relevant publication organs.
    • The IF is unsuitable for evaluating researcher or institutional research activity and quality; other methods like the Science Citation Index and human judgment are necessary.
