The study of people and social phenomena is a broad field which encompasses several subfields such as anthropology, sociology, psychology, and social science. Anthropology is the branch of study that focuses on the study of human societies, cultures, and their development. Sociology, on the other hand, is the study of human behavior in social contexts. Psychology studies the human mind, behavior, and mental processes. Lastly, social science is a broad field that deals with the study of social relationships and interactions. All these fields are different but are related to the study of people and social phenomena. Therefore, these terms can be used as synonyms for the study of people and social phenomena.
