World War II, Barnett returned to the University of Oregon and continued to study Pacific cultures. From 1947 to 1948, Barnett conducted field research on the indigenous people of
Palau. Barnett continued to study American Indians in California and the Pacific Northwest and displaced communities in the Pacific. He served as a visiting lecturer for the
American Anthropological Association from 1960 until 1961. He spoke at college campuses that did not have anthropology departments, trying to spread his knowledge of anthropology.
