Often, the people that anthropologists study have strong feelings about how they are portrayed to the rest of the world. Professional anthropologists must therefore exercise great care in how they conduct and present their work. Anthropological research also has the potential to disrupt a people’s way of life and bring problems into their societies. Anthropologists try to avoid introducing new ideas, technologies, or even food items into the societies they study, because to do so can make people want things that cannot be readily obtained.

Anthropologists also have ethical obligations to those who fund their research activities as well as to students and the interested public who may want to learn from their work. As a basic rule, anthropologists only conduct research openly, honestly, and with the approval of the people they study. In the United States, federally funded projects and research conducted through a public university might face a formal review procedure to make sure that the rights and safety of human subjects are protected.

Today, anthropologists are also obliged to share their research results with the people who helped produce it and to acknowledge the assistance those people give. Anthropologists do not normally pay for specific information, but they may compensate some of the people they study for their time and effort put in as field assistants or informants.

In rare cases a researcher might decide not to work with a particularly isolated and self-sufficient group because to do so might unavoidably introduce disease and open the way for exploitation by other outsiders. Small, self-sufficient societies may have difficulty defending themselves against more powerful groups. For example, information from anthropological work can familiarize governments and businesses with small-scale societies living in remote regions. This information can convince state and business interests to negotiate with the people of such societies about using their land for such projects as road or dam building, mining, or large-scale farming. These so-called development projects can cause great hardships for people who live off the land.

Anthropologists must practice particularly great care if they work directly for governmental or commercial agencies whose political or economic interests could conflict with the interests of the people being studied. For example, in the 1970s and 1980s the Brazilian government hired anthropologists to pacify people who lived in the rain forest and who were being forcibly relocated to make way for the Trans-Amazon Highway. While some anthropologists considered this work unethical, others felt they could help negotiate with the government to minimize damage to the peoples living in the highway’s future path.

Most anthropologists take a position of cultural relativism when making decisions on issues of ethics and rights. This position calls for respect for all cultural differences and opposes culture change imposed on one society by another. Anthropologists know that people derive their individual identity and sense of dignity from their own cultures. This ethical stance reflects the 1948 United Nations Universal Declaration of Human Rights and the United Nations Declaration on the Rights of Indigenous Peoples (drafted in 1994), both of which recognize cultural practices as basic human rights.

This does not mean, however, that anthropologists believe all cultural practices are necessarily good. Extreme relativism, which anthropologists avoid, could condone such acts as the Holocaust or other instances of mass ethnocide (the killing of people of a particular ethnic group). Many cultures may foster practices that clearly harm some individuals. Such practices include infanticide (the killing of infants), the burning of people thought to be witches, and the surgical modification of women’s sexual organs (known as female genital mutilation). Anthropologists might speak out against such practices, but generally they believe that change should come from within a culture and not be imposed from outside it.

Archaeologists have other ethical concerns to consider. Archaeological excavations may unearth sensitive or sacred remains of past cultures with living descendants. Such remains might include the bones of dead ancestors or ancient religious offerings.

Archaeologists respect the claims of cultural groups to ownership of their ancestors’ cultural and physical remains, and work to prevent unauthorized removal of such materials by commercial collectors. They also commonly hand over most or all of their finds to the rightful owners or to museums of the countries in which excavations took place. Sometimes, however, an archaeologist may argue that certain excavated materials have such great scientific importance that they should be analyzed before being returned or reburied.
