The main purpose of conducting peer reviews in science is to ensure research quality and validity. This process involves experts evaluating a study's methodology, data, and conclusions before publication. Peer reviews help identify any biases, errors, or gaps in the research, improving its credibility. Furthermore, this feedback can lead to enhancements in the work, fostering advancements in science as a whole and maintaining a level of rigor in scientific literature. Ultimately, peer review helps the scientific community uphold standards and ensure the reliability of published findings.
