Since the early 1960s, Scandinavian anthropologists have made considerable contributions to the study of ethnicity, an early high point having been reached with the 1967 Wenner-Gren conference leading to the publication of Ethnic Groups and Boundaries in 1969. Later Scandinavian research on ethnicity and social identification more generally has been varied and rich, covering all continents and many kinds of majority/minority relations. However, over the last twenty years, anthropologists have increasingly focused on the study of the relationship between immigrant minorities and the majorities in their own countries. There are some significant general differences between ethnicity research overseas and at home, shedding light on the theoretical constructions of anthropology as well as the 'double hermeneutics' between social research and society. It can be argued that anthropology at home shares characteristics with both European ethnology (with its traditional nation-building agenda) and with sociology (which, in Scandinavia, is almost tantamount to the sympathetic study of the welfare state), adding a diluted normative relativism associated with the political views of the academic middle class (to which the anthropologists themselves, incidentally, belong). The article reflects on the consequences of embroilment in domestic politics for anthropological theory, using the experiences of overseas ethnicity research as a contrast to ethnicity research at home, where anthropologists have been forced, or enabled, to go public with their work.
