Author Contribution Statements and CRediT Taxonomy Explained

Introduction

Authorship disputes and unclear credit allocation have long been challenges in academic publishing. To address this, many journals now require author contribution statements, often structured using the CRediT taxonomy. These statements clarify who did what in a research project and promote transparency and accountability.

This article explains what author contribution statements are, how the CRediT taxonomy works, and how researchers can use it correctly.

What Are Author Contribution Statements?

Author contribution statements:

• Describe each author’s role
• Accompany the published article
• Are reviewed during editorial assessment

They go beyond author order to explain actual contributions.

Why Journals Require Contribution Statements

Journals use them to:

• Prevent honorary or guest authorship
• Resolve authorship disputes
• Improve accountability and transparency

They support ethical publishing standards.

What Is the CRediT Taxonomy?

The CRediT (Contributor Roles Taxonomy) defines standardized roles such as:

• Conceptualization
• Methodology
• Data curation
• Writing – original draft
• Writing – review & editing

It provides a common language across disciplines.

How to Apply the CRediT Taxonomy

Best practices include:

• Assigning roles collaboratively
• Using multiple roles per author if applicable
• Avoiding vague or inflated claims

Accuracy is more important than appearance.

Common Mistakes to Avoid

Avoid:

• Assigning all roles to all authors
• Copy‑pasting generic statements
• Ignoring journal‑specific instructions

Conclusion

Author contribution statements using the CRediT taxonomy improve transparency, fairness, and trust in academic publishing. When used correctly, they protect both researchers and the integrity of the scholarly record.
