Currently, expert systems are being introduced into almost every facet of social service delivery. Because this technology is sustained by computerization, many practitioners believe that objective knowledge will be available to guide program planning. 0ften overlooked, however, is the micro-world that enables computers to operate. The presuppositions associated with this micro- world provide social life with an abstract identity. Therefore, expert systems tend to be insensitive to situational exigencies and generate precise but irrelevant information. To remedy this situation, these systems must be implemented within a reflexive environment, so that they are sensitive to the logic persons use to organize their lives. Several suggestions are made pertaining to creating a reflexive social service agency.
