Peer review is a process used in academic and scientific fields to ensure the quality and credibility of research before it is published. When a researcher submits their work, it is evaluated by other experts in the same field, known as peers. These reviewers assess the study's methodology, findings, and overall contribution to knowledge, providing feedback and suggestions for improvement. This system helps maintain high standards in research and prevents the dissemination of flawed or misleading information. By having peers critically analyze the work, the process fosters trust in published studies, ultimately benefiting the broader community of scientists and scholars.
