Group behavior refers to the ways in which individuals act and interact when they are part of a group. This behavior can be influenced by various factors, including social norms, group dynamics, and the roles individuals take on within the group. People often conform to the expectations of the group, which can lead to changes in their attitudes and actions. Understanding group behavior is important in many fields, such as psychology, sociology, and organizational management. Researchers study phenomena like groupthink, where the desire for harmony in a group leads to poor decision-making, and social loafing, where individuals exert less effort when working in a group compared to working alone.
