Recognition should match accepted accountability
A byline combines scholarly credit with responsibility for a publication. An acknowledgement recognises useful support without assigning the same role. Contributor statements can describe either level more precisely. Status and goodwill do not determine placement; activity and the applicable policy do.
An acknowledgement must not hide qualifying authorship. Someone who designed central analysis, drafted key findings and accepts accountability should not be relegated because they are external or junior. Equally, a senior leader does not become an author through general supervision or funding alone.
Make the decision for the particular paper. A major contribution to a wider programme may be peripheral to one article, while a limited project role may become central to a specific analysis. Examine verifiable work on the published object rather than job title or reputation.
Do not keep qualifying contributors below the threshold
Under the ICMJE approach, four criteria work together. A person making a substantial contribution to conception, data or analysis should have the opportunity to draft or critically revise, inspect the final version and accept accountability. A team must not deny those steps and then use the resulting absence of manuscript involvement to exclude them.
Authorship requires informed agreement. Nobody should be listed without knowledge because their name adds prestige or meets an institutional expectation. Each author understands their own contribution statement, can explain the paper's central conclusions and knows who is responsible for questions outside their expertise.
CRediT roles reveal different work but do not replace eligibility criteria. Many peripheral roles do not add up mechanically to authorship; a few central roles combined with drafting and accountability may qualify. Never count labels as points.
Describe limited assistance precisely and with consent
A useful acknowledgement names the person or organisation and specific help: methodological consultation, technical assistance, recruitment support, language editing or provision of materials. “For support” is vague. Consent matters because a public name can imply endorsement and constitutes personal information.
Paid assistance remains identifiable where policy requires disclosure. Professional writing or substantive editing must not disappear behind “editorial assistance”. Funding receives a separate statement with identifier and sponsor role. Competing interests are also reported separately rather than buried in thanks.
Use respectful collective recognition for groups and communities. Participatory or Indigenous research may require governance-based credit beyond a conventional acknowledgement. A generic sentence cannot replace agreed involvement, data rights or community approval.
Evaluate advice, software and data provision by substance
A single statistics consultation normally supports acknowledgement; designing the entire analytical strategy and interpreting the principal findings may support authorship. Depth, intellectual effect, drafting and accountability matter. Payment neither prevents nor creates qualification.
Software work ranges from routine implementation to novel methodological design. State the output, review and influence on conclusions. Cite a software package appropriately; its developers do not automatically author every application. Direct collaboration is assessed separately.
Providing a dataset alone does not confer authorship. Data curation, provenance verification and interpretation can, however, become substantial contributions. Contract clauses demanding a byline regardless of work conflict with contribution-based policy and should be referred to the institution.
Routine management, arranging meetings or recruiting under a fixed protocol can be important without becoming authorship. If such work also involved methodological decisions or interpretation, describe that additional layer rather than assuming from the job label.
Confirm every classification before submission
- Collect concrete activities from everyone involved.
- Apply authorship criteria and the target journal's rule.
- Enable unresolved candidates to take part in manuscript review.
- Draft contributor and acknowledgement sections separately.
- Obtain consent from named contributors and final author approval.
- Compare the form, PDF and public metadata after publication.
If a person disagrees with the classification, document the contested contribution and seek neutral mediation. Do not solve the issue by omitting them from discussion or offering an unrelated future byline. Preserve the contribution record and the policy used.
The authorship criteria guide expands the threshold. The CRediT role sheet describes activities. More decisions sit in the publication ethics hub. The one foundation route is the guide to verifiable contribution records.
