What is the primary role of peer review in the publication of research?

The primary role of peer review in the publication of research is to help ensure the quality, validity, and reliability of research before it is published. Peer review involves the evaluation of a manuscript by experts in the same field who assess the research for its methodological rigor, accuracy, and contributions to the field. This process is vital as it helps to identify any flaws, biases, or gaps in the research, thereby enhancing the overall quality of published work.

Through peer review, authors receive constructive feedback, which can lead to improvements in their research, ensuring it meets scholarly standards. This scrutiny builds trust in the scientific community by allowing only high-quality research to be disseminated, fostering scientific integrity and advancing knowledge in an informed manner.
