What does mean by Double-Blind Peer Review?

Double-blind peer review is the gold standard process used to assess submissions to many academic journals and conferences. It helps ensure the validity and quality of published research.

What is Double-Blind Peer Review?

  • In a double-blind peer review, the identities of both the reviewers and authors are concealed from each other throughout the review process.
  • Neither party knows who the other is. This minimizes bias and enhances the impartiality of the reviews.

The Process

  • When a researcher submits a paper, the editor sends it to 2-3 expert reviewers in the same field.
  • The reviewers assess the work and recommend acceptance, revisions, or rejection. Comments are sent to the author anonymously.
  • The author revises the paper based on the feedback and resubmits it to the journal. The revised paper may be sent out for another round of reviews.
  • Once accepted, the paper is published and the identities of the authors and reviewers may be revealed.


  • Reduces bias based on author’s name, institution, gender, etc.
  • Encourages reviewers to provide candid feedback without fear of reprisal.
  • Focuses assessment on the quality and merit of the work itself.


  • Reviewers may still recognize writing style or self-citations.
  • The process can be time-consuming.
  • Finding willing reviewers with topical expertise can be difficult.
