The list of authors on a research paper is more than a formality. It tells readers who did the work, who takes responsibility for it, and who deserves credit. When that list is inaccurate, through names added without real contribution or contributors left out, the integrity of research suffers. Two of the best-known problems are gift authorship and ghost authorship.
This article on gift and ghost authorship explains what each practice means, related forms of inappropriate authorship, why they matter, how authorship criteria help prevent them, and practical steps for researchers and institutions.

What Is Authorship?
Authorship signals both credit and accountability. Authors are recognised for their intellectual contribution, but they are also responsible for the accuracy and integrity of the work. Many journals, especially in medicine, follow criteria from the International Committee of Medical Journal Editors (ICMJE), which recommend that authors should:
- Make substantial contributions to the conception or design of the work, or to acquiring, analysing, or interpreting data
- Draft the work or revise it critically for important intellectual content
- Approve the final version to be published
- Agree to be accountable for all aspects of the work
People who contributed but do not meet these criteria are usually listed in the acknowledgements.
Gift and Ghost Authorship at a Glance
| Practice | What Happens | Main Problem |
|---|---|---|
| Gift or honorary authorship | Someone is listed without making a substantial contribution | Unearned credit |
| Guest authorship | A well-known name is added to boost credibility | Misleads readers about who stands behind the work |
| Ghost authorship | A substantial contributor is left off the author list | Hidden influence and missing accountability |
| Coercive authorship | A senior person demands inclusion | Abuse of power |
Gift Authorship Explained
Gift authorship, also called honorary authorship, occurs when a person is listed as an author despite not making a meaningful intellectual contribution to the research.
Common Examples
- A department head added simply because of their position
- A colleague included as a favour or in exchange for future authorship
- Someone who only provided funding, equipment, or general supervision
- A friend added to help their publication record
Guest Authorship
A related practice is guest authorship, where a prominent researcher is added to increase a paper’s chances of acceptance or to give it more authority, even though they played little or no role.
Coercive Authorship
In some cases, senior researchers pressure junior colleagues into listing them as authors. This abuse of power can be difficult for early-career researchers to resist.
Ghost Authorship Explained
Ghost authorship occurs when someone who made a substantial contribution, such as designing the study, analysing data, or writing the manuscript, is not named as an author or acknowledged.
Common Examples
- A professional writer employed by a company drafts a paper but is not acknowledged
- A statistician performs key analyses but is left off the author list
- A junior researcher or student does significant work without credit
- Industry employees shape a study’s content but remain invisible
Ghostwriting in Industry-Sponsored Research
Ghost authorship has been a particular concern in medical research. Documents disclosed in past legal cases showed that some industry-sponsored articles were drafted by company-funded writers, with academic researchers later listed as authors. Readers were not told about the company’s role, raising concerns about hidden bias in medical literature.
Professional medical writers can make valuable contributions when their role is open. Good publication practice guidelines encourage acknowledging their work and disclosing funding sources.
Why Gift and Ghost Authorship Matter
Misleading Readers
Readers rely on author lists to judge expertise and potential conflicts of interest. Inaccurate lists can hide who really shaped the research.
Undermining Accountability
If problems are found in a paper, authors are expected to answer questions and take responsibility. Gift authors may know little about the work, while ghost authors cannot be held accountable at all.
Unfair Credit
Authorship affects hiring, promotion, and funding decisions. Gift authorship gives undeserved advantages, while ghost authorship denies deserving contributors recognition.
Hidden Conflicts of Interest
Ghost authorship can conceal the influence of sponsors or companies, making it harder to assess potential bias.
Damaging Trust
When such practices come to light, they can erode trust in individual researchers, journals, and science as a whole.
Why These Practices Happen
- Pressure to publish and build impressive records
- Hierarchical cultures where seniority is rewarded with authorship
- Unclear or unknown authorship criteria
- Commercial interests in shaping published evidence
- Fear among junior researchers of challenging supervisors
- Lack of early discussion about authorship roles
How to Prevent Inappropriate Authorship
- Discuss authorship early: agree on roles and authorship at the start of a project
- Use clear criteria: follow ICMJE or field-specific guidelines
- Document contributions: use contributor roles, such as the CRediT taxonomy, to describe who did what
- Acknowledge everyone: list non-author contributors, including writers and statisticians
- Disclose funding and writing support: be transparent about sponsors and professional writing help
- Revisit as projects evolve: update authorship agreements when roles change
- Create safe reporting channels: so junior researchers can raise concerns without fear
Contributor vs Author: Where to Draw the Line
Not every helpful person needs to be an author. The following roles are often acknowledged rather than listed as authors, unless the person also meets authorship criteria:
- Providing general laboratory or administrative support
- Securing funding without other intellectual input
- Supplying samples, materials, or equipment
- Offering language editing or proofreading
- General supervision of a research group
On the other hand, people who designed key experiments, analysed data, interpreted results, or wrote substantial parts of the paper usually deserve authorship if they also approve the final version and accept responsibility. Clear, honest acknowledgements give credit to everyone while keeping the author list accurate.
A Note on AI Writing Tools
As generative AI tools become common, new questions have emerged. AI tools cannot be listed as authors, because they cannot take responsibility for the work. However, failing to disclose substantial AI writing assistance may raise transparency concerns similar to ghost authorship. Many journals now require authors to describe any AI use.
What Journals Do
Many journals now ask authors to confirm that they meet authorship criteria, describe individual contributions, disclose writing assistance and funding, and agree to take responsibility for the work. Some require all authors to approve submission directly, and many follow guidance from the Committee on Publication Ethics when handling authorship disputes.
What to Do If You Face an Authorship Problem
- Raise the issue calmly with co-authors, referring to agreed criteria
- Keep records of your contributions
- Seek advice from a mentor, ombudsperson, or research integrity office
- Contact the journal editor if the dispute cannot be resolved
Final Thoughts
Gift and ghost authorship distort one of the most basic signals in research: who did the work and who stands behind it. Gift authorship hands out undeserved credit, while ghost authorship hides real contributors and potential influences. By discussing authorship early, applying clear criteria, documenting contributions, and acknowledging everyone honestly, researchers can ensure that author lists reflect the truth.
