Study: h-index no longer tracks scientific reputation; h-frac works better
anand_bhattad · x · 2026-09-23
A large-scale study by Koltun and Hafner analyzing millions of papers across four fields finds the h-index's correlation with scientific awards has substantially declined due to changing authorship patterns. A fractional citation-allocation analogue, h-frac, outperforms other metrics, suggesting the h-index should be reconsidered in ranking scientists.
