Metascience, also known as science of science, is the systematic study of science itself. It analyzes the practices, structures, and outcomes of Scientific research, including research design, peer review, publication bias, replication, and incentive structures, with the aim of improving the reliability, Transparency, and impact of scientific knowledge production.[1] Emerging at the intersection of the Philosophy of science, the Sociology of science, scientometrics, and research methodology, it draws on empirical and quantitative approaches to evaluate how science is conducted, communicated, and assessed. The field has gained prominence in the context of the replication crisis and broader Debates around open science, research integrity, and evidence-based policy. Its scope encompasses all fields of research and has been described as offering "a bird's eye view of science".
