Gift authorship

Gift authorship and ghost authorship are opposite failures of the same ICMJE authorship test: gift authorship credits someone who did not make a substantive contribution to conception/design, data acquisition/analysis/interpretation, drafting or critical revision, final approval, and accountability; ghost authorship omits someone who did. A useful diagnostic: if removing the named person from the byline would require no change to the manuscript itself, their inclusion was very likely a gift.

Gift authorship most commonly attaches to people with institutional or resource power over the study rather than intellectual input into it: a department head or laboratory director added to every paper the group publishes regardless of personal involvement, a grant holder credited for having funded but not designed or interpreted the work, or a senior colleague added as a courtesy or in the expectation of reciprocal credit on a future paper. COPE’s own terminology groups gift authorship with ‘guest’ and ‘honorary’ authorship as near-synonyms for the same underlying failure, though ‘guest’ is sometimes used more narrowly for a prominent outside name added to lend a paper credibility.

Gift authorship is distinct from a legitimately senior co-author whose contribution was primarily supervisory design and interpretation rather than hands-on data collection — ICMJE’s criteria do not require every author to have done bench work, only to have made one of the four qualifying contributions and to be accountable for the paper as a whole. It is also distinct from coercive citation, which manipulates a paper’s reference list rather than its byline, though both are exercises of an editorial or supervisory power imbalance against someone with less standing to refuse.

Where a proposed authorship change is contested rather than simply undeserved, COPE’s separate flowchart family for authorship changes before and after publication sets out the escalation path — see CASRAI’s overview of COPE’s flowcharts and dedicated guide to resolving authorship order disputes. Contributor-role statements under the CRediT taxonomy are the main preventive mechanism: a role-by-role disclosure makes it harder to add a name without a corresponding, verifiable contribution attached to it.
