Functional theory and groupthink theory provide frameworks for analyzing group communication and decision making. Functional theory focuses on the effectiveness of decision making as a whole, examining how interaction between group members can help or hinder reaching high-quality decisions. Groupthink theory zooms in on problems that can arise from striving for cohesion, leading to dysfunctional decisions due to a lack of critical thinking. While the theories examine different aspects, they are not mutually exclusive. Groupthink can be considered a component of functional theory. Both were influenced by psychologists and examine group processes and decision making from socio-cultural perspectives rather than just individual behaviors.
