peer review process is important because sometimes it proves difficult for researchers and scientists to notice a mistake in the work they have done. chances are high that when the work is reviewed by the other scientists weaknesses can be easily identified and corrected. it also helps in release of unwarranted claims, irrelevant findings, personal views, unacceptable interpretation and deliberate fraud. again, people have confidence with peer reviewed materials because they are sure they have been independently scrutinized by various researchers.
