This Cold War experience and the red-baiting which of course had an even longer history, had an impact which outlasted the Cold War period. The misuses of anthropological knowledge revealed the dangers of an anthropology that was open in its recording of native life. If the anthropologist attempts instead to describe the dynamic processes by which the community adjusts to changing circumstances he concentrates upon particular political battles. In fact, some asked where did scientific anthropology get our informants but exploitation and colonizations of various sorts that sometimes ended in genocide. Some ethnographers just stopped publishing, and some of us delayed our publications for decades.
Native secrets remain secrets and a generation of anthropologists are self-censored.
My own response to closing down was different one. Thus the ethnography of the colonizers would also be revealed to the colonized. And people did start studying up although as if they were isolated, unconnected groups. But by now there was too much generational isolation and self-censorship, the most efficient form of control. This younger generaion of anthropologists who were paving the way to a different anthropology are now in their 50s.
