3.4 Ethnographic Techniques and Perspectives
3.4.1 What is Cultural Relativism and Ethnocentrism?
The guiding philosophy of modern anthropology is cultural relativism—the idea that we should seek to understand another person’s beliefs and behaviors from the perspective of their culture rather than our own. Anthropologists do not judge other cultures based on their values nor view other cultural ways of doing things as inferior. Instead, anthropologists seek to understand people’s beliefs within the system they have for explaining things.
Cultural relativism is an important methodological consideration when conducting research. In the field, anthropologists must temporarily suspend their own value, moral, and esthetic judgments and seek to understand and respect the values, morals, and esthetics of the other culture on their terms. This can be a challenging task, particularly when a culture is significantly different from the one in which they were raised.
During my first field experience in Brazil, I learned firsthand how challenging cultural relativism could be. Preferences for physical proximity and comfort talking about one’s body are among the first differences likely to be noticed by U.S. visitors to Brazil. Compared to Americans, Brazilians generally are much more comfortable standing close, touching, holding hands, and even smelling one another and often discussing each other’s bodies. Children and adults commonly refer to each other using playful nick- names that refer to their body size, body shape, or skin color. Neighbors and even strangers frequently stopped me on the street to comment on the color of my skin (It concerned some as being overly pale or pink—Was I ill? Was I sunburned?), the texture of my hair (How did I get it so smooth? Did I straighten my hair?), and my body size and shape (“You have a nice bust, but if you lost a little weight around the middle you would be even more attractive!”).
During my first few months in Brazil, I had to remind myself constantly that these comments were not rude, disrespectful, or inappropriate as I would have perceived them to be in the United States. On the contrary, it was one of the ways that people showed affection toward me. From a culturally relativistic perspective, the comments demonstrated that they cared about me, were concerned with my well-being, and wanted me to be part of the community. Had I not taken a culturally relativistic view at the outset and instead judged the actions based on my cultural perspective, I would have been continually frustrated and likely would have confused and offended people in the community. And offending your informants and the rest of the community certainly is not conducive to completing high-quality ethnography! Had I not fully understood the importance of body contact and physical proximity in communication in Brazil, I would have missed an important component of the culture.
Trying to perform cultural relativism is difficult even for anthropologists. This is because it is our tendency to try to understand our experience by using cultural experiences we have had previously. The challenge with this is that it can lead to Another perspective that has been rejected by anthropologists is ethnocentrism, —the tendency to view one’s own culture as most important and correct and as a stick by which to measure all other cultures. People who are ethnocentric view their own cultures as central and normal and reject all other cultures as inferior and morally suspect. As it turns out, many people and cultures are ethnocentric to some degree; ethnocentrism is a common human experience. Why do we respond the way we do? Why do we behave the way we do? Why do we believe what we believe? Most people find these kinds of questions difficult to answer. Often the answer is simply “because that is how it is done.” What is missing from this idea of “that’s just the way it is done” is the fact that what, how, and why things are done are culturally determined, ie. they believe what they believe because that is what one normally believes in their culture and doing things any other way seems wrong to their culture.
Ethnocentrism is not a useful perspective in contexts in which people from different cultural backgrounds come into close contact with one another, as is the case in many cities and communities throughout the world. People increasingly find that they must adopt culturally relativistic perspectives in governing communities and as a guide for their interactions with members of the community. This is also helpful when thinking about our global world. If we want to interact as governments in conversation with other governments, we want to try to understand each other even if we do not agree with each other. For anthropologists in the field, cultural relativism is especially important. We must set aside our innate ethnocentrisms and let cultural relativism guide our inquiries and interactions with others so that our observations are not biased. Cultural relativism is, therefore, at the core of the discipline of anthropology.
3.4.2 Can we really be objective? Objectivity and Activist Anthropology?
Despite the importance of cultural relativism, it is not always possible and at times is inappropriate to maintain complete objectivity in the field. Researchers may encounter cultural practices that are an affront to strongly held moral values or that violate the human rights of a segment of a population. In other cases, they may be conducting research in part to advocate for a particular issue or for the rights of a marginalized group.
Take, for example, the practice of female genital cutting (FGC), also known as female genital mutilation (FGM), a practice that is common in various regions of the world, especially in parts of Africa and the Middle East. Such practices involving modification of female genitals for non-medical and cultural reasons range from clitoridectomy (partial or full removal of the clitoris) to infibulation, which involves removal of the clitoris and the inner and outer labia and suturing to narrow the vaginal opening, leaving only a small hole for the passage of urine and menstrual fluid. Anthropologists working in regions where such practices are common often, understandably, have a strong negative opinion, viewing the practice as unnecessary medically and posing a risk of serious infection, infertility, and complications from childbirth. They may also be opposed to it because they feel that it violates the right of women to experience sexual pleasure, something they likely view as a fundamental human right. Should anthropologists intervene to prevent girls and women from being subjected to this practice?
Anthropologist Janice Boddy studied FGC/FGM in rural northern Sudan and sought to explain it from a culturally relativistic perspective. She found that the practice persists, in part, because it is believed to preserve a woman’s chastity and curb her sexual desire, making her less likely to have affairs once she is married. Boddy’s research showed how the practice makes sense in the context of a culture in which a woman’s sexual conduct is a symbol of her family’s honor, which is important culturally.[1]
Boddy’s relativistic explanation helps make the practice comprehensible and allows cultural outsiders to understand how it is internally culturally coherent. But the question remains. Once anthropologists understand why people practice FGC/FGM, should they accept it? Because they uncover the cultural meaning of a practice, must they maintain a neutral stance or should they fight a practice viewed as an injustice? How does an anthropologist know what is right?
Unfortunately, answers to these questions are rarely simple, and anthropologists, as a group, do not always agree on an appropriate professional stance and responsibility. Nevertheless, examining practices such as FGC/FGM can help us understand the debate over objectivity versus “activism” in anthropology more clearly. Some anthropologists feel that striving for objectivity in ethnography is paramount. That even if objectivity cannot be completely achieved, anthropologists’ ethnography should be free from as much subjective opinion as possible. Others take the opposite stance and produce anthropological research and writing as a means of fighting for equality and justice for disempowered or voiceless groups. The debate over how much (if any) activism is acceptable is ongoing. What is clear is that anthropologists are continuing to grapple with the contentious relationship between objectivity and activism in ethnographic research.

3.4.3 Is Anthropology a Science, a Social Science or One of the Humanities?
In truth, anthropology is all of these or just one depending on the type of research being done. Anthropology is all of these because studying humans requires all of these approaches to get a clear and comprehensive understanding of “us”. Anthropologists have described their field as the most humanistic of the sciences and the most scientific of the humanities. Early anthropologists fought to legitimize anthropology as a robust scientific field of study. To do so, they borrowed methods and techniques from the physical sciences and applied them to anthropological inquiry. Indeed, anthropology today is categorized as a social science in most academic institutions in the United States alongside sociology, psychology, economics, and politi- cal science. However, in recent decades, many cultural anthropologists have distanced themselves from science-oriented research and embraced more-humanistic approaches, including symbolic and interpretive perspectives. Interpretive anthropology treats culture as a body of “texts” rather than attempting to test a hypothesis based on deductive or inductive reasoning. The texts present a particular picture from a particular subjective point of view. Interpretive anthropologists believe that it is not necessary (or even possible) to objectively interrogate a text. Rather, they study the texts to untangle the various webs of meaning embedded in them. Consequently, interpretive anthropologists include the context of their interpretations, their own perspectives and, importantly, how the research participants view themselves and the meanings they attribute to their lives.
Anthropologists are unlikely to conclude that a single approach is best. Instead, anthropologists can apply any and all of the approaches that best suit their particular problem. Anthropology is unique among academic disciplines for the diversity of approaches used to conduct research and for the broad range of orientations that fall under its umbrella.
3.4.4 What is the difference between Observation and Participant Observation?
Of the various techniques and tools used to conduct ethnographic research, observation in general and participant observation in particular are among the most important. To some extent we all do observation. Do you ever people-watch at the airport? Ethnographers are trained to pay attention to everything happening around them when in the field—from routine daily activities such as cooking dinner for major events such as an annual religious celebration. They observe how people interact with each other, how the environment affects people, and how people affect the environment. It is essential for anthropologists to rigorously document their observations, usually by writing field notes and recording their feelings and perceptions in a personal journal or diary.
As previously mentioned, participant observation involves ethnographers observing while they participate in activities with their informants. This technique is important because it allows the researcher to better understand why people do what they do from an emic perspective. Malinowski noted that participant observation is an important tool by which “to grasp the native’s point of view, his relation to life, to realize his vision of his world.”[2]
To conduct participant observation, ethnographers must live with or spend considerable time with their informants to establish a strong rapport with them. Rapport is a sense of trust and a comfortable working relationship in which the informant and the ethnographer are at ease with each other and agreeable to working together.
Participant Observation in the Maya Highlands – Katie Nelson
Participant observation was an important part of my own research. In 2003, I spent six months living in two Mayan villages in highland Chiapas, Mexico. I was conducting ethnographic research on behalf of the Science Museum of Minnesota to document changes in huipil textile designs. Huipiles (pronounced “we-peel-ayes”) are a type of hand-woven blouse that Mayan women in the region weave and wear, and every town has its own style and designs. At a large city market, one can easily identify the town each weaver is from by the colors and designs of her huipiles. For hundreds of years, huipil designs changed very little. Then, starting around 1960, the designs and colors of huipiles in some of the towns began to change rapidly. I was interested in learning why some towns’ designs were changing more rapidly than other towns’ as well as in collecting examples of huipiles to supplement the museum’s existing collection.
I spent time in two towns, Zinacantán and San Andrés Larráinzar. Zinacantán was located near the main city, San Cristóbal de las Casas. It received many tourists each year and had regularly established bus and van routes that locals used to travel to San Cristóbal to buy food and other goods. Some of the men in the town had worked in the United States and returned with money to build or improve their family homes and businesses. Other families were supported by remittances from relatives working in the United States or in other parts of Mexico. San Andrés, on the other hand, was relatively isolated and much further from San Cristóbal. Most families there relied on subsistence farming or intermittent agricultural labor and had limited access to tourism or to outside communities. San Andrés was also the site of a major indigenous revolt in the mid-1990s that resulted in greater autonomy, recognition, and rights for indigenous groups throughout Mexico. Politically and socially, it was a progressive community in many ways but remained conservative in others.
I first asked people in Zinacantán why their huipil designs, motifs, and colors seemed to change almost every year. Many women said that they did not know. Others stated that weaving was easy and could be boring so they liked to make changes to keep the huipiles interesting and to keep weaving from getting dull. When I asked people in San Andrés what they thought about what the women in Zinacan- tán had said, the San Andrés women replied that “Yes, perhaps they do get bored easily. But we in San Andrés are superior weavers and we don’t need to change our designs.” Neither response seemed like the full story behind the difference.
Though I spent hundreds of hours observing women preparing to weave, weaving, and selling their textiles to tourists, I did not truly understand what the women were telling me until I tried weaving myself. When I watched them, the process seemed so easy and simple. They attached strings of thread vertically to two ends of the back-strap looms. When weaving, they increased and decreased the ten- sion on the vertical threads by leaning backward and forward with the back strap and teased individual threads horizontally through the vertical threads to create the desired pattern. After each thread was placed, they pushed it down with great force using a smooth, flat wooden trowel. They did the entire process with great ease and fluidity. When I only watched and did not participate, I could believe the Zinacantán women when they told me weaving was easy.
When I began to weave, it took me several days simply to learn how to sit correctly with a back-strap loom and achieve the appropriate tension. I failed repeatedly at setting up the loom with vertically strung threads and never got close to being able to create a design. Thus, I learned through participant observation that weaving is an exceptionally difficult task. Even expert weavers who had decades of experience sometimes made mistakes as half-finished weavings and rejected textiles littered many homes. Although the women appeared to be able to multitask while weaving (stoking the fire, calling after small children, cooking food), weaving still required a great deal of concentration to do well.
Through participant observation, Katie Nelson was able to recognize that other factors likely drove the changes in their textiles. She ultimately concluded that the rate of change in huipil design in Zinacantán was likely related to the pace of cultural change broadly in the community resulting from interactions between its residents and tourists and relatively frequent travel to a more-urban environment. Participant observation was an important tool in her research and is central to most ethnographic studies today.
3.4.5 Let’s Talk: Conversations and Interviews
Another primary technique for gathering ethnographic data is simply talking with people—from casual, unstructured conversations about ordinary topics to formal scheduled interviews about a particular topic. An important element for successful conversations and interviews is establishing rapport, or trust, with informants. Sometimes, engaging in conversation is part of establishing that rapport. Ethnographers frequently use multiple forms of conversation and interviewing for a single research project based on their particular needs. They sometimes record the conversations and interviews with an audio recording device but more often they simply engage in the conversation and then later write down everything they recall about it. Conversations and interviews are an essential part of most ethnographic research designs because spoken communication is central to humans’ experiences.
3.4.6 Let’s Take a Walk: Mapping your Space
Another methodology that anthropologists sometimes use involves mapping our cultural landscape. Whether through drawing, google maps and earth, or through narrative, being able to share images and/or writing about the physical space of your research allows the reader to engage in a different way with the content. I, Vanessa Martinez, decided to create a written narrative of an environmental walk I took in Springfield, Massachusetts as part of my doctoral work to highlight the importance of physical space to my community health equity work.
Walking through Springfield: Vanessa Martínez
On July 19, 2011, I participated in an environmental and educational walk around the North End of Springfield, an area rife with structural barriers to positive health outcomes for its residents. The North End of Springfield is a “food desert” and one of the most socioeconomically disadvantaged neighborhoods in Massachusetts. Originally, the environmental and health coalition had planned a bike event that would allow community members and local leaders to identify the structural violence in the community, understand the history of Springfield’s poor health indicators, and discuss strategies for improving Springfield residents’ health outcomes. After learning about the event, I suggested to Betty Agin, my community collaborator, that the event could also be done as a walk, providing people without bikes the opportunity to participate. She thought it was a great idea and so she contacted the organizers who agreed to promote the event as a bike/walk health event. The day of the event, I arrived wearing workout clothes. I only note my clothing because Betty was dressed as she always was in her Sunday best, only changing her sneakers to walk.
The organizers chose to start our journey at the Pioneer Valley Transit Authority diesel bus garage in the North End neighborhood. The North End may not have a toxic waste dump or a factory emitting smoke into the sky, but the diesel bus garage is a major contributor to air pollution which can pose a serious challenge to human health. Participating in this Springfield community event provided me with a new understanding of the dangers experienced by Springfield residents every day. These dangers are not only what we hear about Springfield in the news nearly every day, violence and poverty; but rather, these dangers stem from being pedestrians in a city after the creation of a highway that split the North End neighborhood in two. This is not unique to Springfield, in fact, many urban centers faced this during Urban Renewal of the 1960s and 70s. However, a consistent thread in the Urban Renewal story across urban America highlights that the newly created highway systems ensured that getting from neighborhood to neighborhood was difficult if not impossible. This remains true today where in some areas, people have to risk crossing railroad tracks or highway entrances in order to get to another neighborhood.
While I walked around Springfield that day, the most prominent features that stood out to me were the elements of hope and community in an urban city that was rife with structural violence. I noticed the vertical ghetto across from the Springfield Riverwalk and Bike Path; this poor community could look across and see the bike path only a few yards away, but the highway divided the community from the river. The only way to access the river would be to walk miles across the city. I was so frustrated that I looked on in amazement searching for hope – we kept walking and I noticed that this same community had a small community garden that was tended to by adults and youth alike. Hope.
When we reached the Gerena School, a community elementary located at 200 Birnie Avenue and built in 1972, our Springfield tour guide discussed the environmental problems experienced by school personnel, students, and community members. The school was built directly under Interstate 91 and adjacent to roadways, a railway, and industrial plant. An underground tunnel was created within Gerena’s property as “a passageway for pedestrians after the construction of Interstate 91 removed the original connecting streets between Memorial Square and Brightwood neighborhoods” (Santana 2012). Construction of the highway system severed the Connecticut River from the rest of the city, just as the railroad had done a century earlier. Recent community outcry over the school’s need for repairs has resulted in local government officials redirecting money for structural repairs. The school suffers from transportation-related indoor air exposures, flooding, moisture, mold, and filth resulting in an unhealthy environment for children. Currently, the EPA is conducting a Health Impact Assessment to determine changes needed to make the school safer and healthier. As we continued our walk past an industrial plant, I had to use my inhaler several times for my asthma.
On our walk, Betty Agin, a Springfield based community organizer, introduced me to Zaida Luna, City Counselor for Ward 1, which includes the North End. Meeting a City Counselor who was committed to the community and showed her support at community events like these was very powerful. As our walk continued, our tour guide pointed out not only what we could see, but what was missing. We saw limited green spaces, barriers to reach the riverwalk, limited pools and family friendly spaces, and the lack of established walking and bike trails. I could not help but think about a framed art piece on my wall with a quote taken from Martin Luther King Jr’s speech “Beyond Vietnam”, an address delivered to the Clergy and Laymen Concerned about Vietnam on April 4, 1967, in New York City; “A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death”.
I began to wonder about the future of the Gerena School, the North End, and Springfield as a whole given that their future was tied up in the narrative of historical oppression, urban renewal, and community action. Furthermore, how is the media driven narrative of personal responsibility mediated by the lived experience of structural and symbolic violence in poor communities? Who was this event really for, and was this experience for the researchers participating in this environmental walk/bike journey to learn about the everyday life experiences of Springfield residents? Was this a healthy event for community members to learn how social factors impact their every-day health choices? Did one’s position as stakeholder change the purpose of the event? The fifty people gathered may have come to the event for different reasons, but at the end of the walk/bike event people seemed eager to take what they had learned and experienced to their fellow community organizers and take action on the disparities existing in their neighborhoods.
3.4.7 Gathering Life Histories
Collecting a personal narrative of someone’s life is a valuable ethnographic technique and is often combined with other techniques. Life histories provide the context in which culture is experienced and created by individuals and describe how individuals have reacted, responded, and contributed to changes that occurred during their lives. They also help anthropologists be more aware of what makes life meaningful to an individual and to focus on the particulars of individual lives, on the tenor of their experiences and the patterns that are important to them. Researchers often include life histories in their ethnographic texts as a way of intimately connecting the reader to the lives of the informants.
3.4.8 The Genealogical Method
The genealogical (kinship) method has a long tradition in ethnography. Developed in the early years of anthropological research to document the family systems of tribal groups, it is still used today to discover connections of kinship, descent, marriage, and the overall social system. Because kinship and genealogy are so important in many nonindustrial societies, the technique is used to collect data on important relationships that form the foundation of the society and to trace social relationships more broadly in communities.
When used by anthropologists, the genealogical method involves using symbols and diagrams to document relationships. Circles represent women and girls, triangles represent men and boys, and squares represent ambiguous or unknown gender. Equal signs between individuals represent their union or marriage and vertical lines descending from a union represent parent-child relationships. The death of an individual and the termination of a marriage are denoted by diagonal lines drawn across the shapes and equal signs. Kinship charts are diagrammed from the perspective of one person who is called the Ego, and all of the relationships in the chart are based on how the others are related to the Ego. Individuals in a chart are sometimes identified by numbers or names, and an accompanying list provides more- detailed information.
3.4.9 Key Informants
Within any culture or subculture, there are always particular individuals who are more knowledge- able about the culture than others and who may have more-detailed or privileged knowledge. Anthro- pologists conducting ethnographic research in the field often seek out such cultural specialists to gain a greater understanding of certain issues and to answer questions they otherwise could not answer. When an anthropologist establishes a rapport with these individuals and begins to rely more on them for information than on others, the cultural specialists are referred to as key informants or key cultural consultants.
Key informants can be exceptional assets in the field, allowing the ethnographer to uncover the meanings of behaviors and practices the researcher cannot otherwise understand. Key informants can also help researchers by directly observing others and reporting those observations to the researchers, especially in situations in which the researcher is not allowed to be present or when the researcher’s presence could alter the participants’ behavior. In addition, ethnographers can check information they obtained from other informants, contextualize it, and review it for accuracy. Having a key informant in the field is like having a research ally. The relationship can grow and become enormously fruitful.
An example of the central role that key informants can play in an ethnographer’s research can be seen in the 2010 Labor and Legality: An Ethnography of a Mexican Immigrant Network where Ruth Gomberg-Munoz provides a complex look at the lives of ten male undocumented immigrants, the Lions, who work as restaurant busboys in Chicago, Illinois. Gomberg-Munoz nicknames her informants “The Lions” because they all come from Leon, Mexico; Leon means lion in Spanish. Gomberg-Munoz writes about their daily lives, which personalizes the faces of illegal immigrants in the context of larger structural violence. Her writing style and the use of the personal stories of undocumented immigrants at the beginning of each chapter allows her readers to become emotionally invested in the lives of these marginalized men. These personal vignettes are contrasted against typical representations of undocumented immigrants found in mainstream media.
3.4.10 Field Notes
Field notes are indispensable when conducting ethnographic research. Although making such notes is time-consuming, they form the primary record of one’s observations. Generally speaking, ethnographers write two kinds of notes: field notes and personal reflections. Field notes are detailed descriptions of everything the ethnographer observes and experiences. They include specific details about what hap- pened at the field site, the ethnographer’s sensory impressions, and specific words and phrases used by the people observed. They also frequently include the content of conversations the ethnographer had and things the ethnographer overheard others say. Ethnographers also sometimes include their personal reflections on the experience of writing field notes. Often, brief notes are jotted down in a notebook while the anthropologist is observing and participating in activities. Later, they expand on those quick notes to make more formal field notes, which may be organized and typed into a report. It is common for ethnographers to spend several hours a day writing and organizing field notes.
Ethnographers often also keep a personal journal or diary that may include information about their emotions and personal experiences while conducting research. These personal reflections can be as important as the field notes. Ethnography is not an objective science. Everything researchers do and experience in the field is filtered through their personal life experiences. Two ethnographers may experience a situation in the field in different ways and understand the experience differently. For this reason, it is important for researchers to be aware of their reactions to situations and be mindful of how their life experiences affect their perceptions. In fact, this sort of reflexive insight can turn out to be a useful data source and analytical tool that improves the researcher’s understanding.
The work of anthropologist Renato Rosaldo provides a useful example of how anthropologists can use their emotional responses to fieldwork situations to advance their research. In 1981, Rosaldo and his wife, Michelle, were conducting research among the Ilongots of Northern Luzon in the Philippines. Rosaldo was studying men in the community who engaged in emotional rampages in which they violently murdered others by cutting off their heads. Although the practice had been banned by the time Rosaldo arrived, a longing to continue headhunting remained in the cultural psyche of the community. Whenever Rosaldo asked a man why he engaged in headhunting, the answer was that rage and grief caused him to kill others. At the beginning of his fieldwork, Rosaldo felt that the response was overly simplistic and assumed that there had to be more to it than that. He was frustrated because he could not uncover a deeper understanding of the phenomenon. Then, on October 11, 1981, Rosaldo’s wife was walking along a ravine when she tripped, lost her footing, and fell 65 feet to her death, leaving Rosaldo a grieving single father. In his essay “Grief and a Headhunter’s Rage,” Rosaldo later wrote that it was his own struggle with rage as he grieved for his wife that helped him truly grasp what the Ilongot men meant when they described their grief and rage.
Only a week before completing the initial draft of an earlier version of this introduction, I rediscovered my journal entry, written some six weeks after Michelle’s death, in which I made a vow to myself about how I would return to writing anthropology, if I ever did so, by writing Grief and a Headhunter’s Rage . . . My journal went on to reflect more broadly on death, rage, and headhunting by speaking of my wish for the Ilongot solution; they are much more in touch with reality than Christians. So, I need a place to carry my anger – and can we say a solution of the imagination is better than theirs? And can we condemn them when we napalm villages? Is our rationale so much sounder than theirs? All this was written in despair and rage.[3]
Only through the very personal and emotionally devastating experience of losing his wife was Rosaldo able to understand the emic perspective of the headhunters. The result was an influential and insightful ethnographic account.
