Decision-making is the process by which individuals and groups identify, combine, and integrate information in order to choose one of several courses of action. Although some social psychologists and sociologists have taken up decision-making as a focused research interest, social psychology generally is seen as informing the emerging interdisciplinary areas of the decision sciences. Decision-making is not guided by a single theoretical framework. Rather a number of theories in which decision-making is either implicit or explicit can be found within symbolic interactionism, exchange theory, rational choice, cognitive consistency theories, and other research on attitudes, beliefs, values, and behaviors. Decision-making has symbolic importance as well. The reality is that individual and group decisions result in outcomes as significant as life and death, war and peace, prosperity and impoverishment, social justice, foreign relations, and the domestic policies of nations. Organizations can succeed or fail as a consequence of the decision-making skills, mindsets, and practices of managers within businesses. The theories and research of sociologists and social psychologists have contributed to the decision sciences and will undoubtedly continue to fit into and work within this growing network of disciplines.
