David Schnieder's cultural analysis of American kinship has proven equally influential. Structuralism also influenced a number of developments in 1960s and 1970s, including cognitive anthropology and componential analysis. This understanding of culture confronts anthropologists with two problems: first, how to escape the unconscious bonds of one's own culture, which inevitably bias our perceptions of and reactions to the world, and second, how to make sense of an unfamiliar culture. Radcliffe Brown’s students were developing social anthropology in the United Kingdom. In the 20th century, most cultural and social anthropologists turned to the crafting of ethnographies. Schneider proposes that kinship is not a field that can be applied cross-culturally, as the theory itself relies on European assumptions of normalcy.  However, this critique has been challenged by the argument that it is linguistics, not cultural divergence, that has allowed for a European bias, and that the bias can be lifted by centering the methodology on fundamental human concepts. Some 20th-century ethnologists, like Julian Steward, have instead argued that such similarities reflected similar adaptations to similar environments. Constance Farrington. This was most obvious in the 'Culture and Personality' studies carried out by younger Boasians such as Margaret Mead and Ruth Benedict.

Observable details (like daily time allotment) and more hidden details (like taboo behavior) are more easily observed and interpreted over a longer period of time, and researchers can discover discrepancies between what participants say—and often believe—should happen (the formal system) and what actually does happen, or between different aspects of the formal system; in contrast, a one-time survey of people's answers to a set of questions might be quite consistent, but is less likely to show conflicts between different aspects of the social system or between conscious representations and behavior.. Morgan, like other 19th century social evolutionists, believed there was a more or less orderly progression from the primitive to the civilized. European "social anthropologists" focused on observed social behaviors and on "social structure", that is, on relationships among social roles (for example, husband and wife, or parent and child) and social institutions (for example, religion, economy, and politics). Anthropology is the study of humanity in all times and places. Anthropology is concerned with the lives of people in different parts of the world, particularly in relation to the discourse of beliefs and practices. Typically, the anthropologist lives among people in another society for a period of time, simultaneously participating in and observing the social and cultural life of the group. In keeping with the times, much of anthropology became politicized through the Algerian War of Independence and opposition to the Vietnam War; Marxism became an increasingly popular theoretical approach in the discipline. Frazer in England worked mostly with materials collected by others – usually missionaries, traders, explorers, or colonial officials – earning them the moniker of "arm-chair anthropologists".  Anthropologists can be employed by institutions such as for-profit business, nonprofit organizations, and governments. , Cultural anthropology has a rich methodology, including participant observation (often called fieldwork because it requires the anthropologist spending an extended period of time at the research location), interviews, and surveys. Tylor and J.G. , Within anthropology's "two cultures"—the positivist/objectivist style of comparative anthropology versus a reflexive/interpretative anthropology—Mead has been characterized as a "humanist" heir to Franz Boas's historical particularism—hence, associated with the practices of interpretation and reflexivity [...], Branch of anthropology focused on the study of cultural variation among humans, Franz Boas, founder of the modern discipline, Wolf, Sahlins, Mintz, and political economy, Geertz, Schneider, and interpretive anthropology, Late twentieth-century shifts in interest.  Nevertheless, key aspects of feminist theory and methods became de rigueur as part of the 'post-modern moment' in anthropology: Ethnographies became more interpretative and reflexive, explicitly addressing the author's methodology; cultural, gendered, and racial positioning; and their influence on his or her ethnographic analysis. Prominent British symbolic anthropologists include Victor Turner and Mary Douglas. , The two types of institutions defined in the field of anthropology are total institutions and social institutions. Like other scholars of his day (such as Edward Tylor), Morgan argued that human societies could be classified into categories of cultural evolution on a scale of progression that ranged from savagery, to barbarism, to civilization. Cultural anthropologists study humanity by immersing themselves in the everyday lives of people in particular societies and cultures. Notable proponents of this approach include Arjun Appadurai, James Clifford, George Marcus, Sidney Mintz, Michael Taussig, Eric Wolf and Ronald Daus. The principle of cultural relativism thus forced anthropologists to develop innovative methods and heuristic strategies. Since 1949, its mission has been to encourage and facilitate worldwide comparative studies of human culture, society, and behavior in the past and present. Cultural anthropology is a branch of anthropology focused on the study of cultural variation among humans.  Another critique, explored at length by American anthropologist David Schneider, argues that kinship has been limited by its inherent Western ethnocentrism. , Parallel with the rise of cultural anthropology in the United States, social anthropology developed as an academic discipline in Britain and in France. Others, such as Claude Lévi-Strauss (who was influenced both by American cultural anthropology and by French Durkheimian sociology), have argued that apparently similar patterns of development reflect fundamental similarities in the structure of human thought (see structuralism). An example of multi-sited ethnography is Nancy Scheper-Hughes' work on the international black market for the trade of human organs.  Many American anthropologists adopted his agenda for social reform, and theories of race continue to be popular subjects for anthropologists today. Modern cultural anthropology has its origins in, and developed in reaction to, 19th century ethnology, which involves the organized comparison of human societies. Anthropology studies the evolution of human culture and therefore provides a wide range of anthropology essay topics that spill into history, biology, sociology, etc. At this time, there was the arrival of "Third World feminism", a movement that argued kinship studies could not examine the gender relations of developing countries in isolation, and must pay respect to racial and economic nuance as well. For example, kinship and leadership function both as symbolic systems and as social institutions. The ethnographer, or cultural anthropologist, tries to get information from many angles to see whole picture--again, striving for that holistic view. It is in contrast to social anthropology, which perceives cultural variation as a subset of a posited anthropological constant. Looking at culture as embedded in macro-constructions of a global social order, multi-sited ethnography uses traditional methodology in various locations both spatially and temporally.
