Coercive Authorship

Coercive authorship — also called coercion authorship in the research-integrity literature — occurs when a person with evaluative or supervisory power over a researcher, typically a principal investigator (PI), lab head, department chair, or thesis supervisor, uses that power imbalance to compel an authorship decision that ICMJE or CRediT contribution criteria would not support: adding themselves (or another favored person) as an author who did not substantively contribute, or removing or demoting a junior researcher who did. The defining feature is not the byline itself, which can look identical to other illegitimate-authorship outcomes — it is the mechanism producing it: the junior researcher’s agreement is not freely given, because refusing carries real, foreseeable career consequences the PI controls or strongly influences, such as a weaker reference letter, delayed thesis approval, reduced access to lab resources, or a chillier path through tenure-track or postdoc renewal.

How coercive authorship differs from gift and ghost authorship

CASRAI’s dictionary already covers two other well-established categories of illegitimate authorship, and it is worth being precise about how coercive authorship is mechanistically different from both, even though the resulting byline can look the same from the outside:

• vs. Gift authorship — a gift authorship is a voluntary, uncoerced act: a collaborator is added as a courtesy, in exchange for resources, or for prestige, with no threat or leverage involved on either side. Coercive authorship produces a similar-looking undeserved credit, but the junior party’s consent is compelled rather than freely given. The two can also compound: a PI may coerce a student into “gifting” a colleague’s inclusion.
• vs. Ghost authorship — ghost authorship is about concealment: someone who substantively contributed (often a paid medical writer) is left off the byline and undisclosed entirely. Coercive authorship is about compulsion, not concealment — the disputed name is usually fully visible on the byline (or fully absent from it), and the mechanism is a power imbalance forcing that outcome, not a decision to hide a contributor’s role.

All three are departures from ICMJE’s four-part authorship test and from proper use of CRediT contribution roles, but only coercive authorship is defined by an exploited power relationship rather than by who consented to what.

The power-dynamics mechanism

Coercive authorship is possible because a PI, supervisor, or senior co-author routinely controls or heavily influences resources a junior researcher depends on: thesis sign-off, funding renewal, letters of recommendation, lab access, co-authorship on future papers, and sometimes visa or employment status. Research-integrity literature on the topic identifies the asymmetry itself — not any single bad actor — as the structural condition that makes coercion possible, which is why guidance in this area (see COPE’s authorship discussion documents) places the primary responsibility for fair authorship practice on senior and principal researchers, precisely because they hold the leverage. A junior researcher facing a coercive demand often has no practical, cost-free way to refuse in the moment, which is what separates this from an ordinary authorship-order negotiation between peers of comparable standing.

Typical patterns described in the literature include a PI requiring their own name (often in the senior/last-author position) on every paper produced by their students or lab regardless of documented contribution to a specific paper; a supervisor instructing a student to relegate or remove a collaborator’s name to make room for someone the supervisor wants credited; and implicit rather than explicit pressure — no direct threat is made, but the power differential and the junior researcher’s dependence on the senior party make refusal feel impossible.

How common is it

Coercive authorship is difficult to measure directly because it depends on self-report by the people with the least power to complain, but several published surveys give a consistent picture of a widespread rather than marginal problem. A review of doctoral-student and faculty surveys found rates ranging roughly from the low teens to around half of respondents depending on country, career stage, and how the question was framed — for example, one long-running survey of Oslo doctoral students found rates rising across cohorts through the 2010s, and a separate multi-country European survey put the rate among students who had already published at roughly a third. Figures vary enough by country and survey design that they should be read as evidence the problem is real and not rare, rather than as a single precise global rate.

Institutional and reporting mechanisms

Because coercive authorship exploits an ordinary supervisory relationship rather than fabricating data or plagiarizing text, it does not always fit neatly inside a narrow research-misconduct definition built around fabrication, falsification, and plagiarism — which is exactly why a separate authorship policy and a separate reporting channel matter, rather than relying solely on a general research misconduct process. Mechanisms institutions and researchers can use include:

• A published, specific institutional authorship policy that states authorship is based on ICMJE/CRediT contribution criteria and is not owed to a supervisor by virtue of the supervisory relationship alone.
• A research integrity office or research ethics/integrity officer as a channel for raising an authorship concern outside the direct chain of supervision — see research integrity and, in the US context, the Office of Research Integrity (ORI) — while noting that some institutional misconduct definitions exclude pure authorship-credit disputes, which is one reason a dedicated authorship-dispute or ombuds channel is needed in addition to, not instead of, a misconduct office.
• An ombudsperson or graduate-student ombuds office, appointed specifically to support students and other junior researchers, who can advise or intervene without the junior researcher having to confront their supervisor directly or file a formal complaint through the same person who controls their evaluation.
• An authorship dispute process at the institution or journal level, formally recognized when raised through that channel rather than resolved informally within the lab.
• Journal- and publisher-level mechanisms, such as requiring an author contribution statement mapped to CRediT roles at submission, which creates a documented record a junior researcher can point to and makes an unsupported byline addition harder to wave through silently.
• Early, explicit authorship discussion at the start of a project, before drafting begins, which research-integrity guidance consistently recommends as the most effective preventive step, since it is far easier to agree on contribution-based authorship in advance than to contest an imposed byline after a manuscript is already written.

A researcher who believes they are facing coercive authorship, and who does not feel safe raising it directly with the person applying the pressure, should generally go first to whichever of the channels above is structurally independent of that person’s own authority — an ombudsperson, a graduate school’s student advocate, or the institution’s research integrity office — rather than a journal, since journals typically expect authorship disputes to be resolved by the institution before they intervene.
