Collective psychology is the study of how groups of people think, feel, and behave together. It examines how social dynamics, cultural influences, and shared experiences shape the mindset of communities. This field explores phenomena such as group identity, social norms, and collective decision-making. Researchers in collective psychology analyze various contexts, including crowds, social movements, and team dynamics. By understanding these group behaviors, psychologists can better address issues like prejudice, conflict, and cooperation. This knowledge can be applied in areas such as education, business, and therapy to improve group interactions and outcomes.
