Sociologists are much interested in groups and organizations and in how groups and organizations function. In their study of society, they apply sociological perspective to their observations. Their perspective is different from ordinary view of world and of ongoing events in world. It is overview, with scientific understanding of society's dynamics and underpinnings.
