What is the primary function of peer-review in scientific work?

The primary function of peer review in scientific work is to validate evidence and conclusions by field colleagues. This process involves critical evaluation by experts who are knowledgeable in the same or a closely related field. They assess the quality, relevance, and significance of the research methodology, data, and results presented in a scientific work. Through this rigorous scrutiny, peer review helps ensure that the research is credible, accurate, and contributes valuable insights to the scientific community.

The peer review system is fundamentally designed to uphold the integrity of scientific literature, reinforcing that published studies have undergone a thorough examination by qualified peers prior to dissemination. This validation process not only supports the reliability of the findings but also strengthens the overall body of scientific knowledge by identifying any errors or biases in the research.
