Behavioral sciences is a field that studies human behavior and its development through interpersonal relationships. It includes disciplines like anthropology, education, political science, psychiatry, psychology, and sociology that focus on how human behavior influences and is influenced by others. The behavioral sciences are a subcategory of the social sciences, which more broadly examine human societies and institutions. Major applications of behavioral sciences include political and marketing polls/surveys to predict human behavior. The field has two main categories: decision sciences which examine individual decision-making, and communication sciences which study communication between organisms.
