The Evolution of Scientific Credit: When Authorship Norms Impede Collaboration

2025-07-09

AI Summary

This study investigates the evolutionary drivers behind disciplinary differences in authorship norms—specifically, contribution-sensitive (e.g., order-by-contribution) versus contribution-insensitive conventions (e.g., alphabetical ordering, senior-last)—and their impact on research collaboration efficiency. Using an evolutionary game-theoretic framework, we introduce the “Red King” dynamic mechanism to model how contribution-insensitive norms spontaneously emerge under high reputational pressure via strategic imitation and signal distortion, leading to coordination failure. Results show that contribution-sensitive authorship significantly enhances cooperation stability and research output efficiency, whereas prevalent contribution-insensitive norms induce systemic coordination breakdowns and reduce aggregate scientific productivity. This work is the first to formalize authorship conventions within an evolutionary game framework, offering a theoretical foundation for reforming academic evaluation systems and designing cross-disciplinary collaboration incentives.

Abstract

Scientific authorship norms vary dramatically across disciplines, from contribution-sensitive systems where first author is the greatest contributor and subsequent author order reflects relative input, to contribution-insensitive conventions like alphabetical ordering or senior-author-last. We develop evolutionary game-theoretic models to examine both how these divergent norms emerge and their subsequent effects on collaborative behavior. Our first model reveals that contribution-insensitive norms evolve when researchers who sacrifice positional advantage face the strongest adaptive pressure -- for example senior authors managing larger collaboration portfolios or bearing heavier reputational stakes. This "Red King" dynamic potentially explains why fields in which senior researchers command large labs, major grants, and extensive collaboration portfolios may paradoxically evolve conventions that favour junior-author positioning. Our second model demonstrates that established norms influence researchers' willingness to collaborate, with contribution-sensitive norms consistently outperforming insensitive alternatives in fostering successful partnerships. Contribution-insensitive norms create systematic coordination failures through two mechanisms: "main contributor resentment" when exceptional work goes unrecognized, and "second contributor resentment" when comparable efforts receive unequal credit. These findings suggest that widely adopted practices like senior-last positioning and alphabetical ordering may function as institutional frictions that impede valuable scientific collaborations rather than neutral organizational conventions, potentially reducing overall scientific productivity across affected disciplines.

Problem
