Reputation and impact in academic careers

Area of Science:

• Bibliometrics
• Scientometrics
• Sociology of Science

Background:

• Reputation is a crucial social construct in science for assessing publications and careers.
• The precise relationship between an individual scientist's reputation and their career progression is not well understood.
• Quantitative research evaluation methods are increasingly prevalent but do not fully clarify reputation's role.

Purpose of the Study:

• To develop a novel framework for quantifying the impact of author reputation on publication citation rates.
• To analyze how a publication's citation rate depends on both its net citation count and the central author's reputation.
• To investigate the mechanisms underlying cumulative advantage in scientific careers.

Main Methods:

• Longitudinal analysis of the careers of 450 highly cited scientists.
• Using total citations of a scientist as a measure of their reputation.
• Developing a stochastic reputation model to simulate career dynamics.

Main Results:

• A citation crossover point (c×) was identified, differentiating the influence of reputation.
• For publications with citations below c×, author reputation strongly influences citation rate, increasing it by ~66% per tenfold reputation increase.
• The reputation effect becomes negligible for publications with citations at or above c×, where citation rate more accurately reflects impact.

Conclusions:

• Author reputation provides a significant early advantage for new scientific publications.
• Citation counts become a more transparent indicator of scientific impact for highly cited works.
• The developed stochastic reputation model successfully replicates statistical patterns observed in real scientific careers.
