Ghost authorship
Ghost authorship occurs when a person who made substantial contributions to a research publication is not listed as an author, deliberately hiding their involvement. It is a recognised form of authorship misconduct condemned by the ICMJE, COPE and major publishers.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
What ghost authorship is
A ghost author is a person who has made a substantial contribution to a research publication — often writing or significantly revising the manuscript — but who is not listed as an author and whose involvement is not disclosed. The "ghost" is hidden from the reader, the editor and the record.
The ICMJE requirement is unambiguous: those who meet authorship criteria should be listed, and those who do not meet the criteria but contributed should be acknowledged. Omitting a qualifying contributor from the byline without disclosure breaches both obligations.
Medical ghostwriting scandals
The most extensively documented ghost authorship occurs in medical literature, particularly in industry-funded research. Internal industry documents disclosed in litigation related to Vioxx (rofecoxib) and selective serotonin reuptake inhibitors (SSRIs) revealed that manuscripts were drafted by professional medical communications agencies under pharmaceutical company direction, then submitted under the names of academic physicians who had limited involvement. The named authors provided credibility; the actual drafters were not disclosed. These scandals prompted major reforms, including the ICMJE and COPE positions now in place.
ICMJE and COPE positions
The ICMJE states that ghost authorship is "not acceptable" and requires journals to ask whether anyone who meets authorship criteria was excluded. COPE considers ghost authorship a serious ethical violation and provides guidance for editors who discover undisclosed contributors after publication. Both bodies place the primary responsibility on the listed authors, who must confirm on submission that all contributors meeting authorship criteria are named.
Consequences and how journals detect it
Ghost authorship can result in post-publication corrections, expressions of concern, or retraction if the undisclosed contributor is identified. Journals increasingly ask detailed author-contribution questions at submission, require CRediT statements, and may ask whether professional medical writers were used. Institutional investigations can follow if ghost authorship is suspected, particularly in the context of industry-funded research. Contributorship statements — detailing who wrote the manuscript — are the most practical safeguard.

- Examples: Vioxx and SSRI litigation documents revealed systematic medical ghostwriting
- ICMJE: explicitly states ghost authorship is not acceptable
- COPE: treats it as a serious ethical violation with post-publication remedies
- Safeguard: CRediT contribution statements requiring "Writing — original draft" attribution
- Consequence: corrections, expressions of concern, or retraction if discovered
Common questions
FAQ
What is ghost authorship?+
Ghost authorship is when a person who made a substantial contribution to a research publication — often writing the manuscript — is not listed as an author and their involvement is not disclosed. It is considered research misconduct.
Why is ghost authorship a problem?+
It conceals who actually produced the work, hides potential conflicts of interest (e.g. industry funding), misleads readers about a paper's provenance, and violates the principle that all qualifying contributors must be named.
Is medical ghostwriting illegal?+
It is not generally a criminal offence, but it can be a breach of journal policies, research-integrity codes, and, in some jurisdictions, consumer-protection rules when undisclosed industry involvement influences clinical practice. It has led to regulatory and institutional investigations.
How can ghost authorship be prevented?+
By requiring CRediT contributor-roles statements at submission (particularly "Writing — original draft"), asking authors to confirm that no qualifying contributor is excluded, and having transparent policies about professional medical writer involvement.
What is the difference between ghost authorship and gift authorship?+
Ghost authorship is hiding a contributor who should be listed; gift authorship is listing someone who should not be. Both are forms of authorship misconduct, but they are opposites in direction.
