Intellectual and Ethical Guidelines for Authorship in the Sciences

Intellectual and Ethical Guidelines for Authorship in the Sciences

Authorship in the sciences carries prestige, visibility, and career impact — but it also carries responsibility. Scientific papers form part of the permanent scholarly record; the names on a paper signal who stands behind the design, execution, analysis, and claims. To protect research integrity and ensure fair credit, scientific communities and journals converge on a set of intellectual and ethical guidelines. This article consolidates those expectations, explains how to apply them in day-to-day collaboration, and provides practical tools (templates, checklists, and example statements) you can adapt for your next manuscript.

1) The Core Principle: Substantial Contribution + Accountability

Across major publishers and funders, authorship typically requires both a substantive intellectual contribution and willingness to take responsibility for the work. The widely adopted framework of the International Committee of Medical Journal Editors (ICMJE) is a good benchmark. In short, a scientific author should:

• Contribute substantially to the conception/design of the work or to acquisition, analysis, or interpretation of data;
• Draft or critically revise the manuscript for important intellectual content;
• Approve the final version to be published;
• Agree to be accountable for the integrity of the work, including cooperating in resolving questions about accuracy.

All four conditions should be met. Individuals who helped in other meaningful ways (funding acquisition, administrative support, general supervision, language polishing, routine instrumentation) are important contributors, but those contributions do not necessarily confer authorship. Acknowledge them transparently.

2) Contributors vs. Authors: Drawing the Line

Activity	Typical Credit	Notes
Hypothesis generation; study design; protocol creation	Authorship	Conceptual input is central to authorship.
Data collection with methodological input; specialist analysis	Authorship	When combined with drafting or critical revision.
Statistical modelling; software development specific to study	Authorship	Especially when analysis choices influence conclusions.
Funding acquisition only; general lab oversight	Acknowledgment	Not sufficient for authorship without intellectual contribution.
Administrative support; logistics; scheduling; clerical tasks	Acknowledgment	Credit contributors by name and affiliation if possible.
Language editing; proofreading; typesetting	Acknowledgment	May require permission for public acknowledgment depending on contract.

3) Roles on a Multi-Author Paper

• Guarantor: One (or more) authors who accept full responsibility for the entire paper’s integrity. Often a senior investigator; distinct from the corresponding author role.
• Corresponding Author: The primary contact for editors and readers. Manages submission, revisions, ethics forms, data/code availability statements, permissions, and author approvals.
• Author Order: Typically reflects contribution (first author: largest hands-on intellectual work; last author: senior leadership). In some fields, alphabetical order or co-first/co-senior notes are standard; always follow discipline norms and disclose “equal contribution” explicitly.
• Affiliations & ORCID: Provide complete affiliations and persistent IDs; many journals require ORCID to improve attribution accuracy.

4) Contributorship Statements (CRediT Taxonomy)

Many journals use the CRediT taxonomy to make contributions transparent. Typical roles include: Conceptualization, Methodology, Software, Validation, Formal Analysis, Investigation, Resources, Data Curation, Writing—Original Draft, Writing—Review & Editing, Visualization, Supervision, Project Administration, and Funding Acquisition.

Example CRediT statement:

AB: Conceptualization, Methodology, Investigation, Writing—Original Draft
CD: Software, Formal Analysis, Visualization, Writing—Review & Editing
EF: Resources, Data Curation, Validation
GH: Supervision, Funding Acquisition, Project Administration, Guarantor

5) Deciding Authorship Early: An Agreement You Can Reuse

Misunderstandings often arise late in a project. Prevent them by agreeing in writing on criteria and anticipated order at project start, then revisiting at milestones.

Mini-authorship agreement (template):

Project: [Title]
Criteria: We adopt ICMJE/discipline criteria for authorship.
Provisional order: [Names in order]; equal-contribution notes if applicable.
Roles: [Name] first draft; [Name] analysis; [Name] supervision/guarantor.
Data & code: Repository/DOI; who prepares documentation.
Dispute resolution: Step 1 internal meeting → Step 2 department mediator → Step 3 institution policy.
Signatures & Date

6) Ethical Red Lines (and How to Avoid Crossing Them)

• Honorary/guest authorship: Adding names for prestige or politics undermines integrity. Only list individuals who meet authorship criteria.
• Ghost authorship: Omitting individuals who wrote or analysed substantially is equally problematic. Offer authorship; if declined, acknowledge with permission.
• Duplicate submission/publication: Do not submit the same manuscript to multiple journals simultaneously or republish substantially the same content without transparent cross-reference and editor permission.
• Salami slicing: Do not fragment a single study into minimal publishable units to inflate counts. Distinct questions warrant distinct papers; document prespecified secondary analyses.
• Undeclared conflicts of interest: Financial, personal, or institutional interests can bias interpretation. Disclose fully and early.
• Data fabrication/falsification: Zero tolerance. Guarantors and corresponding authors must ensure data integrity and availability in line with policies.

---

7) Special Situations

• Students and trainees: Substantial work merits authorship and often first authorship. Supervisors should facilitate, not obstruct, fair credit.
• Large consortia & group authorship: Use bylines such as “The XYZ Collaboration,” with a roster and contribution appendix. Make guarantor roles explicit.
• Equal contribution: If two or more authors contributed comparably, include a footnote (“These authors contributed equally”) and reflect it in contributor statements.
• Deceased or incapacitated authors: Journals may allow inclusion if contributions meet criteria and co-authors can vouch for accuracy. Note the circumstance respectfully.
• AI tools: Generative or analytical AI cannot be an author; disclose use (e.g., language assistance, code generation) and take responsibility for content and data security.

8) The Corresponding Author’s Compliance Checklist

• [ ] All listed authors meet field/journal authorship criteria and have approved the final manuscript.
• [ ] Author order, equal contributions, affiliations, and ORCID IDs are confirmed.
• [ ] CRediT contributorship statement drafted and verified by each author.
• [ ] Ethics approvals/IRB numbers, consent statements, clinical trial registration (if applicable) included.
• [ ] Data and code availability statements (with DOIs/links) prepared; permissions for third-party content secured.
• [ ] Funding, conflicts of interest, and role of the funder disclosed precisely.
• [ ] Acknowledgments reviewed for accuracy and permission to name individuals.

9) Acknowledgments: Give Credit Without Diluting Authorship

Use the acknowledgments section to recognize important but non-author contributions. Examples:

• “We thank Dr X for access to the [facility/equipment] and Ms Y for administrative support.”
• “Language editing was provided by [service/individual] (no role in study design, analysis, or interpretation).”
• “We acknowledge the ABC Core for mass spectrometry and the DEF Biobank for sample provision.”

Obtain permission from named individuals to be acknowledged, especially if the wording might imply endorsement.

10) Handling Disputes Fairly

Disagreements over authorship can derail submission. A structured process helps:

1. Revisit written criteria: Compare each person’s contributions to the agreed policy (ICMJE/department guidelines).
2. Facilitated discussion: Meet with a neutral chair (PI or co-PI). Focus on facts and documented contributions.
3. Departmental mediation: Engage graduate program directors or research integrity officers if needed.
4. Institutional policy: Follow formal procedures as a last resort; document all steps.

11) Transparency in the Manuscript and Cover Letter

In-manuscript statements improve trust and speed review:

• “Author contributions (CRediT): …”
• “Data and materials availability: Data are deposited at [repository, DOI]; code available at [URL/DOI].”
• “Competing interests: The authors declare …”

Cover-letter note (example):

All authors meet authorship criteria, have approved the final version, and agree to be accountable for the work. 
CRediT roles are provided in the manuscript. No prior publication overlaps materially with this submission.

---

12) Permissions, Reuse, and Prior Dissemination

• Figures/tables: If reusing or adapting, secure permission or rely on a licence that allows it (e.g., CC BY). Always attribute.
• Preprints & theses: Disclose prior posting, cite it, and explain what is new (data, analysis, scope).
• Conference proceedings: Policies vary; if expanding to a journal paper, clarify additions and obtain necessary permissions.

IJ—Conceptualization, Methodology, Writing—Original Draft; 
KL—Software, Formal Analysis, Visualization; 
MN—Investigation, Data Curation; 
OP—Supervision, Funding Acquisition, Writing—Review & Editing, Guarantor.

13.2 Authorship Confirmation Email (Internal)

Subject: Authorship confirmation for “[Manuscript Title]”
Dear all,
Please review the attached final draft, author order, affiliations, ORCID IDs, and CRediT roles. 
Reply “APPROVE” or propose edits by [date]. Approval indicates you meet authorship criteria, 
approve the final version, and agree to be accountable for the work.
Thanks, [Corresponding Author]

13.3 Guarantor Statement

[Name] serves as guarantor and accepts full responsibility for the work, 
had access to the data, and controlled the decision to publish.

14) Ethics Beyond the Byline: Data, Code, and Reproducibility

Authorship responsibility extends to future verifiability of your results. Where policies permit, deposit data and code in trusted repositories with persistent identifiers. Provide enough documentation (README, data dictionary, environment files) for others to reproduce analyses. If access must be controlled (privacy, IP), state the process and conditions clearly.

15) Key Takeaways

• Earned credit: Authorship requires substantial intellectual contribution plus accountability.
• Clarity: Decide authorship early, document roles, and confirm order before submission.
• Transparency: Use CRediT, conflict disclosures, and data/code statements to make contributions visible.
• Integrity: Avoid honorary/ghost authorship, duplicate submission, and salami slicing.
• Compliance: Follow journal/funder policies on permissions, ethics approvals, and availability statements.

Handled thoughtfully, authorship is more than a list of names — it is a map of responsibility and contribution that strengthens the credibility and impact of your science.
