The first is informed consent. This implies that before conducting any research, the anthropologist must provide research participants with all relevant information regarding the study so that they can consent to participate. The second is personal honesty. It is unethical to mislead informants or attempt to obtain information under false pretenses. The third ethical issue is ethical and cultural relativism. Because belief systems and cultural practices are relative, anthropologists often find themselves among groups of people who participate in practices that conflict with the anthropologist's personal ethics. The final important ethical issue anthropologists must grapple with is the researcher's responsibility to research subjects. Field anthropologists are on the front lines of pressing issues in their research community. This raises questions about whether or not the anthropologist should assist them financially or otherwise, which could subsequently skew their findings. If, however, the researcher does nothing to assist the research team, they may find that the informants are unwilling to do so.
