Collective behavior is a field of study that explores how individuals in a group or society behave collectively and how their actions influence one another. This research area often looks at patterns of behavior, decision-making processes, and group dynamics that emerge when individuals interact with one another in social settings. The goal of studying collective behavior is to understand how and why groups of people come together, form identities, and carry out coordinated actions. This research can be applied to a wide range of fields, including sociology, psychology, anthropology, and political science.
