What strategies do cultural anthropologists use that is differ from others social scientists?

The closest social science to cultural anthropology is sociology. The biggest difference between these two very similar fields is that cultural anthropology prefers the use of ethnographic observations, integrating with the community, learning the language of the locals and becoming so comfortable that they hopefully can start to observe and think about things more from the perspective and in the language of the community rather then from the perspective of an outsider. Sociologists, alternatively, make more use of statistics and frequently study societies more broadly on a macro scale then on the micro scale that cultural anthropologists attempt. Learning the language and integrating with the society in question is NOT the priority of the sociologist. I'm not saying that either field can't work within the others primary mode of study, but as a general rule this is how it is. Otherwise, they are both social sciences.
