Social science
Social science is a category of academic disciplines, concerned with society and the relationships among individuals within a society. Social science as a whole has many branches. These social sciences include, but are not limited to: anthropology, archaeology, communication studies, economics, history, human geography, jurisprudence, linguistics, political science, psychology, public health, and sociology. The term is also sometimes used to refer specifically to the field of sociology, the original "science of society", established in the 19th century. For a more detailed list of sub-disciplines within the social sciences see: Outline of social science.
Behavioural sciences
Behavioural sciences abstract empirical data to investigate the decision processes and communication strategies within and between organisms in a social system. This involves fields like psychology, social neuroscience ethology, and cognitive science. In contrast, social sciences provide a perceptive framework to study the processes of a social system through impacts of social organization on structural adjustment of the individual and of groups. They typically include fields like sociology, economics, public health, anthropology, demography and political science.
