Blind evaluation of papers is a form of evaluation, which means that reviewers evaluate and grade papers without knowing the identity of the author. The purpose of this move is to ensure the fairness and objectivity of the evaluation and avoid the prejudice of the judges on the author's identity, background and other factors from affecting the evaluation results.

In blind evaluation of papers, reviewers can only evaluate papers according to their content and quality, and cannot be interfered by the author's academic reputation or other interpersonal relationships. This evaluation method is not only conducive to protecting the author's academic independence and copyright, but also conducive to ensuring the fairness and objectivity of academic evaluation.

It is worth noting that blind review is not the only way to review. Some journals or academic institutions also adopt different evaluation forms, such as single-blind evaluation or double-blind evaluation, and the specific forms vary from institution to institution.

Blind examination of papers is an important part of academic evaluation and one of the necessary measures to improve the objectivity and fairness of academic evaluation.
