 Ethnographers and development specialists have shown that a long-term relationship is necessary to develop a rapport and mutual respect with the local community, and argue that to succeed at collaboration archaeologists must make a long-term commitment in order to understand the dynamics of the social context of their research.Without this depth of knowledge archaeologists risk making decisions with unintended consequences.For example, collaborations and repatriations have been more successful where archaeologists and American Indians have met on a regular basis and developed both friendship and mutual respect.
