Sociology is the scientific study of society. Hence, sociology organizes information and data regarding groups by social agents as well as groups social agents independently in accordance with those factors deemed salient to the plausibility of the emergence or formation of some group. It also tries to develop models that describe quantitative relationships among variables relevant to the relationships across or among social agents as well as between extra-social factors and large-scale trends in social behavior. It also seeks to develop causal narratives regarding changes in different aspects of society, or, put in other terms, changes in groups or their formation. However, given the embeddedness and active participation of the sociologist in the object of study (i.e., in society), sociology maintains a philosophical and theoretical comportment as evaluation of empirical study must also retain a critical attitude regarding the social position and social processes involved in the undertaking of empirical study. This aspect of sociology is referred to as ´theoretical sociology,´ and allows for diverse empirical set-ups and more varied evaluation. Sociologist also seek to evaluate the practical consequences of policy. Sociology must of course start from an agnosticism regarding the scope of its object of study given the notion of society is given to it pretheoretically.
