Expert consensus in research refers to the general agreement among experts in a particular field on a specific topic or issue. This consensus is usually reached through a formal process in which experts review and analyze relevant evidence, data, and research findings to come to a collective agreement or recommendation. Expert consensus is often used to guide decision-making, policy development, and practice in various fields such as medicine, psychology, and climate science. It provides a valuable and reliable source of information for policymakers, practitioners, and the general public.
