What is the process of double blind peer review and how does it ensure the quality and impartiality of research publications?

Double blind peer review is a process where the identities of both the author and the reviewers are kept confidential from each other. This ensures that the evaluation of the research is based solely on its quality and merit, rather than on the reputation or background of the author. By maintaining anonymity, double blind peer review helps to reduce bias and ensure impartiality in the assessment of research publications.
