Reversing the byline hierarchy: The effect of equalizing bias on the accreditation of primary, secondary and senior authors

- Equalizing bias (EqB) is the difference between equal and actual coauthor credit.
- EqB accounts for a massive shift of credit from primary to secondary authors.
- Equal credit scores grow increasingly biased as the number of coauthors increases.
- Credit lost by unrecognized senior authors becomes part of other coauthors' EqB.
- EqB is universally unaccounted for in metrics relying on biased equal credit.
