This document discusses and compares the fields of social science, natural science, and humanities. It defines social science as the systematic study of societies and human behavior through disciplines like economics, anthropology, history, political science, psychology, and sociology. Social science and natural science are both empirical sciences that use measurable evidence, but social science deals with human subjects rather than objects and is less predictable. Humanities are concerned with heritage, arts, and what makes us human, while social science applies empirical methodology to present objective facts about human lives and society. The document outlines some of the main branches of social science and what each discipline involves.
